List two major benefits of high-yield modern agriculture. Uses less land to produce more food Help to protect biodiversity in many areas by reducing the destruction of forests and grasslands for farming
How to increase the yields of a farm?
Proper and timely watering of the farm is critical for better yields. Thus, without adequate irrigation measures, it is not possible to plant high-yielding seeds and do a proper fertilization.
What are the advantages of modern agriculture?
Advantages of modern agriculture During the latter half of the twentieth century, what is known today as modern agriculture was very successful in meeting a growing demand for food by the world’s population.
What is average crop yield and why is it important?
It is considered to be probably the most important measure of each farmer’s performance, as it embodies the result of all the efforts and resources invested by agrarians in the development of plants on their fields. Given this, no wonder that most farmers find themselves in a constant quest called “How to increase the average crop yield per acre?”.
Is high-yield farming good for the environment?
Extensive field data suggest that impacts on wild populations would be greatly reduced through boosting yields on existing farmland so as to spare remaining natural habitats. High-yield farming raises other concerns because expressed per unit area it can generate high levels of externalities such as greenhouse gas emissions and nutrient losses.
What are the advantages of modern agriculture?
Advantages of modern agriculture Modern technology has been able to catch up with a growing demand for food by world’s population. An increase in yield of primary crops and lower food prices is as the result of modern technology like new crop varieties, the use of big data and precision agriculture.
What is high yield agriculture?
Examples of high-yield strategies include enhanced pasture systems and livestock breeds in beef production, use of chemical fertilizer on crops, and keeping dairy cows indoors for longer.
What are the major harmful environmental impacts of agriculture?
Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
What is the advantages in agriculture?
Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world’s working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.
What is the benefit of high yield crops?
Some of the advantages are mentioned below: Higher and improved yield of crops. Most of the high yield crops are dwarf and hence, their plants are stronger and can withstand strong winds. The high yield crops give better response to fertilizers and thus, their production rate increases substantially.
Why is crop yield important in agriculture?
Sometimes crop yield is referred to as “agricultural output.” In a global economy, crop yield data is vital to measure if crops that are produced can adequately provide enough food for a nation’s food supply, livestock feed, and energy sources.
What is modern agriculture?
Modern agriculture is an ever-changing approach to agricultural innovations and farming practices that helps farmers increase efficiency and reduce the amount of natural resources needed to meet the world’s food, fuel and fiber demands.

What were the advantages of modern agriculture?
Advantages of modern agriculture During the latter half of the twentieth century, what is known today as modern agriculture was very successful in meeting a growing demand for food by the world’s population. Yields of primary crops such as rice and wheat increased dramatically, the price of food declined, the rate of increase in crop yields generally kept pace with population growth, and the number of people who consistently go hungry was slightly reduced.
What are the basic practices of modern agricultural systems?
Basic Practices of Modern Agricultural Systems Modern agricultural systems have been developed with two related goals in mind: to obtain the highest yields possible and to get the highest economic profit possible.
What are the key factors that contribute to the success of modern agriculture?
Access to modern machinery and machinery are key factors for success of modern agriculture. Modern agricultural machinery plays different roles on different cop stages that will eventually result to better production. Activities such as planting, tilling, fertilizer application, and pest control processes heavily rely on modern machinery.
Why is agriculture technology important?
Agricultural technology is one of the most amazing and a revolutionary area of agricultural field since it focuses on sufficient food production to meet the ever- rising demand of the population. Modern farmers can now do better than the previous farmers.
What is the purpose of crop rotation?
The rotation of different types of crops in the same piece of land gives the soil an allowance to recover the nutrients that were used up by the previous crop. This technique is one of the powerful natural tools in modern agriculture, eradicating effects of same cultivation year after year.
What is the purpose of pesticides in agriculture?
Pesticides. Chemical substances that are used to control pests attacking crops are essential farming practise. However, there are quite a number of that contaminate plants causing health issues. In modern agriculture, growers are adopting the use of integrated pest management as a sustainable alternative for pesticides.
Why is irrigation important?
Irrigation practices. Water is essential for any growth in crops. It is the blood of agriculture life. The development of the crop pattern, crop combination, and the extent of the size to be planted is water dependent. Proper and timely watering of the farm is critical for better yields.
Why is bio fertilizer important?
They facilitate increased production of high yielding seed culture. Using bio-fertilizers is even better because they are sustainable and environmentally friendly.
How do we manage farming and food systems to meet rising demand?
How we manage farming and food systems to meet rising demand is pivotal to the future of biodiversity. Extensive field data suggest that impacts on wild populations would be greatly reduced through boosting yields on existing farmland so as to spare remaining natural habitats. High-yield farming raises other concerns because expressed per unit area it can generate high levels of externalities such as greenhouse gas emissions and nutrient losses. However, such metrics underestimate the overall impacts of lower-yield systems. Here we develop a framework that instead compares externality and land costs per unit production. We apply this framework to diverse data sets that describe the externalities of four major farm sectors and reveal that, rather than involving trade-offs, the externality and land costs of alternative production systems can covary positively: per unit production, land-efficient systems often produce lower externalities. For greenhouse gas emissions, these associations become more strongly positive once forgone sequestration is included. Our conclusions are limited: remarkably few studies report externalities alongside yields; many important externalities and farming systems are inadequately measured; and realizing the environmental benefits of high-yield systems typically requires additional measures to limit farmland expansion. Nevertheless, our results suggest that trade-offs among key cost metrics are not as ubiquitous as sometimes perceived.
Can comparisons be made across production systems?
Comparisons must be made across production systems that could, in principle, be substituted for one another, so they must be measured or modelled identically and in the same place or, if not, potential confounding effects of different methods, climate and soils must be removed statistically.
How does intensive agriculture work?
In traditional intensive agriculture, farmers increase their inputs of human and draft-animal labor, animal manure for fertilizer, and water to obtain higher crop yields. If the weather cooperates, farmers can produce enough food to feed their families and have some left over to sell for income. 4.
How many people survive on grain crops?
About two of every three people in the world survive primarily by eating one or more of three grain crops–rice, wheat, and corn. Only a few species of mammals and fish provide most of the world’s meat and seafood.
How do farmers save water?
A newer form of industrialized agriculture uses large arrays of greenhouses to raise crops indoors, in water-short, arid areas such as parts of Spain, farmers can save water by using greenhouses, because they can deliver water more efficiently to greenhouse crops than they can to outdoor crops.
How does the Yarra Valley Farm work?
It is powered partly by solar electric and solar hot water systems and makes use of several greenhouses to capture solar energy for growing food throughout the year. The farm produces an amazing diversity of crops–150 varieties of vegetables along with organic herbs and sunflowers.
What are the crops that are produced by the farm?
It also produces chickens, turkeys, goats, fish such as tilapia and perch, and honeybees. And the farm’s nutrients are recycled in creative ways. For example, wastes from the farmed fish are used as nutrients to raise some of the crops.
Is agriculture an agribusiness?
In the United States, industrialized farming has evolved into agribusiness, as a small number of giant multinational corporations increasingly control the growing, processing, distribution, and sale of food in U.S. and global markets.
How do agrarians increase crop yields?
Agrarians aiming to increase crop yields must take care of their plants throughout their development and up the end of the growing season. Depending on the problem that may arise, farmers use different substances to diminish the impact of weeds, pests or diseases on crop yield.
How does soil affect crop yield?
The quality of soil, i.e. its fertility, is one of the main factors that affect crop yields. Apart from agricultural productivity, the soil quality also influences the cost for a farmer to grow one or another plant, as some of them require certain ratios of specific elements in the soil, like mineral particles, organic matter, water, air, etc. To attain increased crop yields, farmers need to closely monitor soil conditions on their land plots. One of the best ways to maintain the soil in good health is to practice crop rotation, among others. Alternating plants on a given field plot prevents soil exhaustion and breaks pest cycles, which will result in better agricultural output and, therefore, will increase the average crop yield per acre.
Why do agrarians need to sow seeds?
Agricultural productivity depends on the quality of seeds with which farmers sow their fields. Therefore, in order to increase crop yield on their farmlands , agrarians are recommended to sow only certified seeds that have passed all the necessary quality controls.
Why is scouting important?
Scouting is one of the important parts of agribusiness management aimed to ensure proper development of plants and increase crop yields. Often, when a grower has large fields, it is difficult and non-effective to scout acre by acre, as it is time-consuming and resource-intensive.
Why is it important to monitor crop growth?
From the early stage of development through budding and up to harvesting, it is very important to monitor plant health in order to timely detect any problem that can arise on a given farmland (be it related to pest infestations, plant diseases, weeds, etc.) and that can affect the crop yield .
How to maintain soil health?
One of the best ways to maintain the soil in good health is to practice crop rotation, among others. Alternating plants on a given field plot prevents soil exhaustion and breaks pest cycles, which will result in better agricultural output and, therefore, will increase the average crop yield per acre.
Why is the agrarian performance important?
It is considered to be probably the most important measure of each farmer’s performance, as it embodies the result of all the efforts and resources invested by agrarians in the development of plants on their fields.
