What is cropping system?

The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. It includes all spatial and temporal aspects of managing an agricultural system. Historically, cropping systems have been designed to maximise yield, but modern agriculture is increasingly concerned with promoting environmental sustainability in cropping systems.


What is tillage in agriculture?

Tillage is the primary method by which farmers manage crop residues. Different types of tillage result in varying amounts of crop residue being incorporated into the soil profile. Conventional or intensive tillage typically leaves less than 15% of crop residues on a field, reduced tillage leaves 15–30%, and conservation tillage systems leave at least 30% on the soil surface. The differences observed across these systems are diverse, and there is still considerable debate concerning their relative economic and environmental impact, but a number of widely reported benefits have led to a major shift towards reduced tillage in modern cropping systems.


What does leaving residues on the soil surface do?

In general, leaving residues on the soil surface results in a mulching effect which helps control erosion, prevents excessive evaporation, and suppresses weeds , but may necessitate the use of specialised planting equipment. Incorporating residues into the soil profile results in rapid decomposition by soil microorganisms, which makes planting easier and in some cases could mean that nutrients will be made available to plants sooner, but limited erosion control and weed suppression are provided.


What is crop choice?

Crop choice. Crop choice is central to any cropping system. In evaluating whether a given crop will be planted, a farmer must consider its profitability, adaptability to changing conditions, resistance to disease, and requirement for specific technologies during growth or harvesting. They must also consider the prevailing environmental conditions …


Why is it important to manage crop residues?

Some of the nutrients contained in these dead tissues are made available to crops during decomposition, reducing the need for fertiliser inputs. Leaving residues in place also increases the soil organic matter (SOM), which has a number of benefits. Specific management practices can have a number of other impacts.


What is the importance of soil moisture?

Soil moisture content is an important factor in plant development, and must be maintained within a range throughout the growing period. The range of tolerable moisture conditions varies from crop to crop. Irrigation and fine-textured amendments can be used to increase soil moisture, whereas coarser-textured amendments and technologies such as tile drainage can be used to decrease it.


Which crop is used as both food and fodder?

It grows in the regions which experience rainfall throughout the year. Maize: This Kharif crop is used as both food and fodder. It grows well in alluvial soil. Pulses: India is the largest consumer and producer of pulses in the world.


What are the crops that are grown to feed the human population?

The crops that are grown to feed the human population are known as food crops . There are a number of food crops grown in the country. Rice: It is the staple food crop in a majority of regions in the country. Rice is a Kharif crop that requires high temperature, heavy rainfall and high humidity for proper growth.


What is a rabi crop?

Why is strip cropping used in agriculture?

It is a regular practice on sloped lands to control soil erosion. However, strip cropping in agriculture applies to even terrains as well when two or more species are cultivated together. It is similar to intercropping this way because alternative species grow in-between the cash plants.


What is strip cropping used for?

Besides soil protection, strip cropping with cover crop may be additionally used as green manure or grazing and forage material. Rotations of ground cover bands with high and low soil-holding properties mitigate dust emissions and reduce the destruction by winds.


Why do we use strip cropping?

It is typical to use strip cropping to reduce soil erosion, both on sloped and flat fields, especially by combining species with different root systems. Deep-rooted plants fix the soil with their roots and protect it from rill water erosion, being a natural barrier to flowing streams.


How does strip cropping help the environment?

By reducing soil erosion, preserving field fertility, and eliminating environmental pollution, strip cropping makes farmlands suitable for use in the future as well. Thus, the approach is not only beneficial for soil and yields but belongs to sustainable farming practices, meeting their primary goal of soil conservation and rational consumption of natural resources. With smart agricultural software, the feasibility of strip cropping agriculture implementation considerably increases. Request a demo and see how Crop Monitoring can help you manage your fields.


Why are crop bands important?

Compared with up and down rows, planting along the contour simplifies machinery movement and field operations. It also protects soil from rill formation and sedimentation by slowing runoffs down.


How does strip farming work?

Cultivation with strip farming implies that each of the bands will be managed separately. That’s why tracking the vegetation state and conducting activities will also be separate for each species. By generating vegetation and productivity maps with the Zoning feature, a farmer will get important information as to differentiated fertilization and irrigation needs in each of 2 to 7 zones. Thus, satellite imagery enables crop producers to identify exact areas requiring fertilization or irrigation and decide application amounts. In the case of strip cropping, this approach makes particular sense because different bands consist of different plants, at possibly different development stages, and different needs.


What is crop band?

Crop bands are arranged in parallel lines across the field without following the contours. This method is suitable either for flat areas or gentle slopes, and it is used if the soil is not too prone to erosion. Field strip farming is also a solution when the previous practice is not feasible or rational due to relief specifics (e.g., irregular or wavy lands).


What is cropping system?

The term cropping system refers to the crops and crop sequences and the management techniques used on a par-ticular field over a period of years. This term is not a new one, but it has been used more often in recent years in dis-cussions about sustainability of our agricultural production systems. Several other terms have also been used during these discussions:


How does cropping affect water quality?

A cropping system thus affects water quality to the extent that it keeps soil in place, releases little pesticide, and takes up nutrients that would otherwise leave fields in drainage or runoff water. Perennial cropping systems such as permanent pasture that are managed with-out use of excess nutrients or pesticides generally excel at preserving water quality. More common systems such as the corn–soybean rotation, even if managed well by using appropriate amounts and forms of nitrogen fertilizer, only those pesticides needed, and little or no tillage, will still in many cases lose more nitrogen to surface water than will perennial crops. Tile drainage, by making it possible for water to move out of a field to a stream or river, often increases nutrient loss from a field. But with proper care it is possible to produce crops with minimal effects on water quality.


What are winter cover crops?

Rye, wheat, ryegrass, hairy vetch, and other grasses and legumes are sometimes used as winter cover crops in the Midwest. The primary purpose for using cover crops is to provide plant cover for soil to help reduce erosion dur-ing the winter and spring. Winter cover crops have been shown to reduce total water runoff and soil loss by 50% or more, although the actual effect on any one field will de-pend on soil type and slope, the amount of cover, planting and tillage methods, and intensity of rainfall. A cover crop can protect soil only while it or its residue is present, and a field planted after cover crop residue has been displaced or buried by tillage may lose a great deal of soil if there is intense rainfall after planting. The use of winter cover crops in combination with no-till corn may reduce soil loss by more than 90%. Cover crops are promoted as a way to improve soil tilth, and they sometimes contribute nitrogen tothe followingcrop.


What crops can grow in Illinois?

Many crops other than corn, soybean, and small grains will grow in Illinois, and many will grow quite well, but most have not been produced commercially. A few such crops have been produced on a limited scale and sold in limited quantities, either to local markets or for transpor-tation to processing or export facilities. Many alternative crops are associated with high market prices and high potential income per acre, and thus they catch the attention of entrepreneurial producers who might hear about them. But such crops may have requirements (especially for quality) that can be difficult to meet under Illinois condi-tions, have high labor costs or other costs of production, or have very limited or inconsistent markets due to unpredict-able production elsewhere.


What is the most common crop rotation in Illinois?

The corn–soybean rotation (with only one year of each crop) is still by far the most common one in Illinois. This crop sequence offers several advantages over growing either crop continuously. These advantages have been affected by the development of glyphosate-tolerant corn and soybean (which has tended to lessen the advantages of rotation with regard to weed control) and by the develop-ment of Bt-rootworm hybrids in corn (which has lessened the disadvantage in cost of control, and possibly in loss of yield, historically tied to rootworm control in continu-ous corn). The rotation with soybean reduces nitrogen fertilizer rate compared to continuous corn, but today the perceived disadvantage for continuous corn is less of an incentive to rotate than it has been in the past.


Is canola rapeseed oil?

Rapeseed, a member of the mustard family, is a crop that has been used as an oilseed in many countries for centu-ries. Canola is rapeseed that was genetically improved by Canadian scientists (hence, the “can” in “canola”), result-ing in low erucic acid content in the oil and low levels of glucosinolates in the meal produced from the seed. These developments improved the quality of both edible oil and protein meal used in animal feed.


Is sunflower a crop in Illinois?

Sunflower is an alternative crop that some Illinois farmers have produced profitably. Sunflower usually grows in areas of low humidity, and Illinois weather is often more humid than is ideal.


How does cropping affect soil health?

Cropping systems, including crop diversification, crop rotation and intercropping, and related agronomic practices used in agriculture impact soil health and quality from various spatial and temporal aspects ( Vukicevich et al., 2016 ). Cropping systems were initially designed to maximize yield from agro-systems, but modern agriculture has become increasingly concerned about the environmental sustainability of cropping systems ( Fargione et al., 2018 ). The goal of soil health maintenance is to ensure long-term stable high productivity and environmental sustainability of cropping systems under five essential function evaluation standards, namely nutrient cycling, water relations, biodiversity and habitat, filtering and buffering, and physical stability and support ( Hatfield et al., 2017 ). Fig. 1 illustrates an example of how an optimized cropping system increases soil health, relative to monoculture.


What are the limitations of cropping systems?

One of the most important, well-known limitations of the evaluation of soil health in our current cropping systems is the lack of a healthy control soil that could be used for reference and comparison purposes. This is not surprising because soil is spatially heterogenous (in fact, it is defined more by the heterogeneity of its properties and processes than any average measure) and temporally dynamic. In response to this lack of a healthy reference soil, Karlen et al. (2001) reported that trends over time provide the most suitable way to assess the effects of soil management on soil functional sustainability (i.e., soil health) under different cropping systems. Another problem with the definition of soil health as “the capacity of a given soil to perform its functions” is that often, and specifically depending on the intended soil use, the abovementioned soil functions can be conflicting or incompatible. Therefore, this paper reviews the impact of conventional cropping systems on soil health, microbiological indicators, and other indicators related to soil health evaluation and soil degradation caused by anthropogenic activities in agriculture to provide useful information for future cropping system design and optimization in agriculture.


How do prairie strips help the ecosystem?

Compared with other cropping systems, prairie strips can improve soil water infiltration, soil organic matter content, and nutrient retention with fewer management challenges in agroecosystems ( Poeplau and Don, 2015 ). While longer crop rotations can reduce soil disease levels and enhance financial impacts of some additional crops, such as small grains and forages, these require additional labor, equipment, and management practices. Therefore, prairie strip practices could be combined with other crop rotations to provide better ecosystem services for soil health ( Schulte et al., 2017 ). For example, perennial native grass species grown with other crops in rotation offer substantial diversification opportunities to help meet both economic and environmental goals ( Robertson et al., 2017; Werling et al., 2014 ), but the levels of benefits brought by prairie strips varies with crop species planted close to prairie strips and agronomic managements practiced in field ( Brandes et al., 2016 ). Overall, prairie strips are a relatively low-cost approach with many benefits for improving soil health, requiring minimal changes to existing farming operations.


Why is crop diversification important?

Crop diversification is often described as the ‘planned diversity’ of cropping systems ( Matson et al., 1997 ). It is not only critical for optimizing crop production but also important for increasing soil health by balancing soil biodiversity, enhancing soil nutrient use efficiency, and reducing soil-borne pathogens ( Barbieri et al., 2019; Gurr et al., 2016 ). It is well accepted that optimized crop diversification has various benefits, not only to growers but also to the environment, as increasing crop diversity can enhance heterogeneity of soil chemical nutrients, soil physical structures, and functional microorganisms at different spatial scales, leading to improved soil health and crop yields ( Bardgett and van der Putten, 2014; Maron et al., 2011 ). However, this relationship can vary with species redundancy and host-specificity of some soil-borne pathogens ( Naeem, 1998; Zhu et al., 2000 ). For example, Bainard et al. (2017b) reported that increased crop diversity did not necessarily reduce soil-borne diseases; in particular, including more pulse crops in rotations significantly increased the pathogen index, which may be due to an increase in pulse-specific pathogens.


How does intercropping improve soil health?

Intercropping practices can enhance soil health by reducing artificial chemical pollution ( Lemaire et al., 2014 ), inhibiting soil disease ( Vukicevich et al., 2016 ), increasing plant root function ( Bukovsky-Reyes et al., 2019 ), enhancing soil nutrient and spatial use efficiency ( Hinsinger et al., 2011) and promoting bio-functionalities of soil microorganisms ( Sun et al., 2019 ). For example, a study in a semi-arid area in Gansu, China, found that intercropping systems, including corn, wheat, and faba beans, had about 23%, 4%, and 11% higher root biomass and organic C and N contents in the top 20 cm soil layer than those species in rotation ( Cong et al., 2015 ). In Pernambuco, Brazil, intercropping cassava with pigeon pea and beans significantly reduced black root rot ( Scytalidium lignicola) in cassava by up to 50% compared with cassava in monoculture ( de Medeiros et al., 2019 ). In addition, the intercropping soil had higher organic C and other nutrients, microbial biomass, and enzyme activities, than the monoculture soil, which were correlated with a decline in disease severity ( de Medeiros et al., 2019 ).


What are the benefits of intercropping?

Although increased spatial plant diversity is typically associated with enhanced resource use in intercropping systems, substantial environmental benefits can be gained by intercropping with carefully chosen crop species ( Matson et al., 1997 ). For example, grasses usually dominate in soils with high nitrogen availability, and legumes are advantageous for soils due to their symbiotic relationship with nitrogen-fixing bacteria; thus, grass–legume intercrops can self-regulate soil nitrogen levels to optimize soil nutrient use and reduce the carbon footprint ( de Araújo Santos et al., 2019 ). However, the ecological influences and biological functions of these crops in intercropping systems are not well understood, as intercropping systems with higher yields do not necessarily reflect better soil health ( Jungers et al., 2019 ). For example, total shoot biomass increased significantly in an intercropping practice using Medicago sativa and Dactylis glomerata, relative to sole cropping, but the N 2 O production rate also increased, suggesting that understanding the nature of these intercropping designs is critical for soil and environmental health maintenance ( Graf et al., 2019 ).


Is soil a resource?

Soil is an extremely complex ecosystem and a highly valuable resource from an ecocentric and anthropocentric perspective. Soil is undoubtedly one of our most essential and strategic resources, due to its many crucial functions, including: (i) provision of food, fiber, and fuel; (ii) decomposition of organic matter (e.g., dead plant and animal material); (iii) recycling of essential nutrients; (iv) detoxification of organic contaminants; (v) carbon sequestration; (vi) regulation of water quality and supply; (vii) habitat provision for myriad of animals and microorganisms (soil is an important biodiversity reservoir); (viii) source of raw materials (clay, sand, gravel). Unfortunately, soil has been and is currently being rapidly degraded at a global scale due to a range of invasive anthropic activities in intensive agriculture, with concomitant adverse effects on human and ecosystem health. This is concerning as soil is a non-renewable resource at a human temporal scale (i.e., soil loss and degradation are not recoverable within a human lifespan).


How has multiple cropping changed the way of farming?

Multiple cropping or Multi cropping system in agriculture has changed the way of farming. With continuous growing population in the world the demand of food supply is increasing every year. In every part of the world, mainly in developing countries like India there is a huge potential of growth in agriculture sector.


What is multiple cropping?

Multiple cropping is the practice of growing two or more crops in the same farm land. Instead of growing one crop in a field we grow two or more than two crops in the field in the same season. But this doesn’t mean that we can grow any two or more crops together.


How does multi cropping help?

Adopting this cropping system helps in reducing the food crises of a country. Multi cropping system reduces the overall cost of production. For more than one crop growing on the same field that have similar water, sunlight, fertilizer needs helps to reduce the overall cost.


Why is multiple cropping important?

Multiple cropping system helps farmers to double their crop productivity and income. It also helps to reduce the dependency on growing a single crop in a particular growing season.


How does the farming system affect crop selection?

System of farming adopted affects the crop selection. It depends on whether a farmer is doing purely crop farming or farming integrated with livestock production. Selection of crop depends on the crop production practices such as: Monoculture, Multiple Cropping, Hedge row-strip cropping,


Why should crops be selected?

The crops and therefore the varieties to be grown should be selected supported their adaptability to the prevailing conditions within the farm.


Why are there wide possibilities in crop selection?

Wide possibilities in crop selection could be generated because of stable supply of water. In addition, the accessibility of the farm to and from the market will influence the selection of crops.


What is double cropping?

Get Matched with a Lender, Click Here. Double cropping is a way to double (or increase) the amount of produce you grow without increasing the size of your acreage. The most common crop to double crop is wheat, with soybeans being the next most popular crop to be double-cropped.


How to make double cropping successful?

Tips to Make Double Cropping Successful. Timing and weather are two of the most important factors in the success of double cropping. While you can’t control the weather, you can control your timing.


How to double crop wheat?

Other tips for double cropping include: 1 Make sure to manage the residue during the wheat harvest to protect the integrity of the soybeans 2 Choose soybeans with a later harvest date to ensure that you have enough time before the first frost to harvest the soybeans 3 Try to control the pests and potential disease to your acreage to ensure that you don’t lose both crops


Can you spread the cost of land over the various crops?

You can spread the cost of the land over the various crops, giving you a greater return on your investment per acre


Is double cropping profitable?

Double cropping is a fragile process that if it works, can be very profitable. Understanding the ins and doubts of the process and timing it perfectly is the best way to have a great outcome.


What is cover crop?

Cover Crops. Cover crops can be broadly defined as any non-cash crop grown in addition to the primary cash crop. These crops have the potential to increase soil organic matter and fertility, reduce erosion, improve soil structure, promote water infiltration, and limit pest and disease outbreaks. There are numerous benefits to cover cropping, …


Why do farmers use cover crops?

Some reasons to implement cover crops into a crop management regime include to slow erosion, improve soil health, enhance water infiltration, smother weeds, control pests and diseases, and increase biodiversity. For organic farmers and farms that do not rely on chemical applications of fertilizer, a common reason for growing cover crops is to add nitrogen to the soil; leguminous cover crops can provide a substantial amount of nitrogen. Crops planted following a cover crop can more readily utilize this plant-available form of nitrogen. Conventional farming systems may include cover crops as a method of increasing soil organic matter and improving the physical structure of the soil. In these situations, farmers may choose rapidly growing grasses or species with extensive root systems as a cover crop.


Why are cover crops left in the field?

Because cover crops are left in the field, there is no direct profit to the farmer for harvested crop products.


When did cover cropping start?

Cover cropping was extensively used around the country in the first half of the 20th century. With the development of selective pre- and post-emergent herbicides, many farmers transitioned away from growing cover crops in the 1950s. In recent years the increased focus on soil quality and reducing chemical inputs has led to a renewed interest in the potential benefits of including cover crops in an agricultural production system.


Why are cover crops considered weeds?

While they can reduce the impact of specific pests and pathogens, some cover crops may act as reservoirs for other insects, rodents, weeds, or diseases. If improperly selected or managed, some cover crops can persist as weeds when the field is transitioned and prepared for subsequent plantings.


What are the factors that determine the success of a cover crop?

Site specification , timing, and cropping history are all factors in choosing the most appropriate cover crop species to introduce into a system.


Is cover cropping good for agriculture?

There are numerous benefits to cover cropping, though, as with any management technique, there are tradeoffs and limitations that must be considered. In many situations cover cropping can lead to a decreased reliance on fossil fuels and improved agricultural productivity.
