Conservation agriculture was developed in Brazil and Argentina in the 1970s, and adheres to three core principles:
- Minimize soil disturbance: absent tilling, farmers seed directly into the soil.
- Maintain soil cover: farmers leave crop residues after harvesting or grow cover crops.
- Manage crop rotation: farmers change what is grown and where.

What are examples of conservation agriculture?
Here are some examples:Hoe farming. Many African farmers cultivate by hand, using hoes. … Small holder farming with draught animals. Farmers who own (or can hire) oxen or donkeys to pull implements can use a different set of conservation agriculture practices.
What is conservation agriculture PDF?
Conservation agriculture (CA) is characterized by minimal soil disturbance, diversified crop rotations, and surface crop residue retention to reduce soil and environmental degradation while sustaining crop production.
What is conservation agriculture Upsc?
Conservation Agriculture (CA) is a set of soil management practices that minimize the disruption of the soil’s structure, composition and natural biodiversity. CA has proven potential to improve crop yields, while improving the long-term environmental and financial sustainability of farming.
How conservation agriculture is done?
What are the principles of conservation agriculture? Conservation agriculture is based on the interrelated principles of minimal mechanical soil disturbance, permanent soil cover with living or dead plant material, and crop diversification through rotation or intercropping.
What are the principles of conservation agriculture?
The 3 principles of CA are: minimun tillage and soil disturbance. permanent soil cover with crop residues and live mulches. crop rotation and intercropping.
What is conservation agriculture?
Conservation agriculture is based on the interrelated principles of minimal mechanical soil disturbance, permanent soil cover with living or dead plant material, and crop diversification through rotation or intercropping.
Why is conservation agriculture important?
While conservation agriculture provides many benefits for farmers and the environment, farmers can face constraints to adopt these practices. Wetlands or soils with poor drainage can make adoption challenging.
What do farmers use to remove weeds?
Organic farmers apply tillage to remove weeds without using inorganic fertilizers. Conservation agriculture farmers, on the other hand, use a permanent soil cover and plant seeds through this layer. They may initially use inorganic fertilizers to manage weeds, especially in soils with low fertility.
What is sustainable intensification?
Sustainable intensification is a process to increase agriculture yields without adverse impacts on the environment, taking the whole ecosystem into consideration. It aims for the same goals as conservation agriculture. Conservation agriculture practices lead to or enable sustainable intensification.
How does conservation agriculture help the environment?
Conservation agriculture conserves natural resources, biodiversity and labor. It increases available soil water, reduces heat and drought stress, and builds up soil health in the longer term.
What is zero tillage?
Zero tillage is combined with intercropping and crop rotation, which means either growing two or more crops at the same time on the same piece of land, or growing two different crops on the same land in a sequential manner . These are also core principles of sustainable intensification.
How can sustainable farming improve resilience?
However, sustainable farming methods can do the opposite — increase resilience to climate change, protect biodiversity and sustainably use natural resources . One of these methods is conservation agriculture. Conservation agriculture conserves natural resources, biodiversity and labor.
What is conservation agriculture?
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as “A farming system that promotes minimum soil disturbance (i.e. No-till farming ), maintenance of a permanent soil cover, and diversification of plant species. It enhances Biodiversity and natural biological processes …
Why is conservation important?
Conservation has become critical because the global population has increased over the years and more food needs to be produced every year (New Standard 1992).
What is the role of mulch in agriculture?
According to the article “The role of conservation agriculture and sustainable agriculture”, the layer of mulch that is built up over time will become like a buffer zone between soil and mulch and this will help reduce wind and water erosion.
Why is no till farming important?
No-till farming has caught on as a process that can save soil organic levels for a longer period and still allow the soil to be productive for longer periods (FAO 2007). Additionally, the process of tilling can increase time and labor for producing that crop.
What are the benefits of conservation?
These benefits include less erosion possibilities, better water conservation, improvement in air quality due to lower emissions being produced, and a chance for larger biodiversity in a given area.
What is land sparing?
Land sparing is another way that producer and conservationist can be on the same page. Land sparing advocates for the land that is being used for agricultural purposes to continue to produce crops at increased yield. With an increase in yield on all land that is in use, other land can be set aside for conservation and production for biodiversity. Agricultural land stays in production but would have to increase its yield potential to keep up with demand. Land that is not being put into agriculture would be used for conserving biodiversity (Green, et al. 2005). In fact, data from the Food and Agriculture Organization shows that between 1961 and 2012, the amount of arable land needed to produce the same amount of food declined by 68 percent worldwide.
What is no till farming?
These practices are well known by most producers. The process of no-till is one that follows the first principle of CA, causing minimal mechanical soil disturbance.
What is conservation agriculture?
Conservation Agriculture (CA) is a sustainable approach to agricultural production which aims to protect soil from erosion and degradation, improve its quality and biodiversity, contribute to the preservation of natural resources, water and air, whilst optimising yields.
What are the economic benefits of the approach?
Economic benefits of the approach include labour and fuel saving in perennial crops, cost-savings in annual crops, increase of yields, reduction of run-off and erosion which contribute to increased agricultural production costs.
Where did conservation agriculture originate?
Conservation agriculture was developed in Brazil and Argentina in the 1970s, and adheres to three core principles: Minimize soil disturbance: absent tilling, farmers seed directly into the soil. Maintain soil cover: farmers leave crop residues after harvesting or grow cover crops.
How many hectares of land will be in conservation agriculture by 2035?
Based on historic growth on large farming operations, our analysis projects the total area under conservation agriculture will continue growing from 148 million hectares to peak at 400-327 million hectares by 2035.
What does “conserve” mean in Latin?
The Latin root of conserve means “to keep together. ”. Conservation agriculture abides by these principles to keep the soil together as a living ecosystem that enables food production and helps redress climate change.
Soil management in Conservation agriculture
The biological activity of soil like the spatial arrangement of soil components is fundamental to sustaining agricultural productivity and determines in their complexity the soil health and fertility.
Conventional Vs Conservation Agriculture
Both conventional farming and Conservation agriculture include a different variety of operations. The main operations are field preparation, planting, fertilization, weeding, harvesting, and field operations after the harvest.
Organic Agriculture Vs Conservation Agriculture
These two agricultural systems maintain a balance between agricultural resources by using crop rotation and protect the soil’s organic matter.
How does Conservation agriculture differ from climate-smart agriculture?
Both conservation and climate-smart agriculture are similar, their purposes are different. These agriculture systems aim to have a positive effect on the environment and sustainably intensify smallholder farming systems. It helps farmers to adapt to and increase crop yields despite climate risks.
Pest, weed, and fertility management in Conservation agriculture
In any agricultural system, pest, weed, and fertility management are critical issues. Any limitation related to pest, weed, and soil fertility should be assessed and addressed before implementing conservation agriculture.
What is conservation agriculture?
Conservation agriculture means farming in harmony with nature. In a forest, the ground is covered with a per- manent layer of litter. The soil is rich in or- ganic matter and has many earthworms, beetles and other tiny animals. There is a wide range of different plants, all growing together.
Why is conservation important in agriculture?
Conservation agriculture helps these farmers cut costs while increasing their yields. To overcome shortages of labour and farm power. Many farm households suffer from a severe lack of labour and farm power. Hunger and malnutrition combine to make people weak, unable to work hard, and vulnerable to disease.
What is the purpose of mulch in conservation agriculture?
In conservation agriculture, crop residues left on the field, mulch and special cover crops protect the soil from erosion and limit weed growth throughout the year. Mix and rotate crops. In conventional farming, the same crop is sometimes planted each season.
How can conservation agriculture be sustainable?
Conservation agriculture has three basic principles: Disturb the soil as little as possible Keep the soil covered as much as possible Mix and rotate crops. We will look at each of these in turn. Disturb the soil as little as possible.
What is mix and rotate agriculture?
mix and rotate crops. ) can be applied in a wide range of conditions. How farmers put them into practice will vary from place to place, depending on many factors. Conservation agriculture can be practised on different types of farms, with different combinations of crops and sources of power.
Why do farmers use more and more fertilizer?
To get a good yield, farmers often apply more and more fertilizer. With less moisture in the soil, plants are more vulnerable to drought. They start to wilt after a few days without rain. Conservation agriculture enables farmers to reverse this trend.
When to slash cover crop residue?
Slashing and spreading of crop and cover crop residues in year 2 and beyond, followed by planting directly through residues. Complete weeding may not be required; roguing and shallow weeding instead. Needs training to use weed wiper. Planting of cover crops is possible after applying herbicide.
Improving soil conditions
Concerns about soil erosion affecting soil productivity in rainfed areas have resulted in an emphasis on trying to stop negative effects on crop yields attributed to erosion and runoff. This has been attempted by putting cross-slope barriers in fields designed to catch or divert soil and water moving downslope.
Zero tillage has been successfully practised in the United States for several decades, with regular annual growth in the total area. In Latin America there has been an impressive rate of adoption and accelerating growth over the past two decades.
Implementing conservation agriculture
Planting a crop in the residues of the previous crop, which is the essence of conservation agriculture, is fast becoming a successful and sustainable cropping practice, especially in the subhumid tropics. Implicit in this practice is the absence or limitation of tillage practices that incorporate surface residues or disrupts soil porosity.
Effects of conservation agriculture
Farmers’ own experiences confirm what was anticipated by results of two six-year experiments with wheat and soybean between 1978 and 1984, comparing effects of conventional tillage, minimum tillage/scarification and zero tillage (Table 14).
Observations about residue-based zero tillage systems in Latin America
From the full application of both the concepts and integrated techniques of residue-based zero tillage (also called Conservation Agriculture), farmers have achieved many direct and indirect benefits, often recorded together on individual farms (Instituto CEPA/SC, 1999; FAO, 2001b).
Constraints of conservation agriculture and some approaches to overcome them
Conservation agriculture has been successfully employed in subhumid as well as humid climates, but there are still some constraints in semiarid environments that may hinder its immediate application. Typical of these constraints are:
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as “A farming system that promotes minimum soil disturbance (i.e. no-till farming), maintenance of a permanent soil cover, and diversification of plant species. It enhances biodiversity and natural biological processes above and below the ground surf…
The Food and Agriculture Organization of the United Nations (FAO) has determined that conservation agriculture (CA) has three key principles that producers (farmers) can proceed through in the process of CA. These three principles outline what conservationists and producers believe can be done to conserve what we use for a longer period of time.
The first key principle in CA is practicing minimum soil disturbance which is essential to maintai…
In the field of CA there are many benefits that both the producer and conservationist can obtain.
On the side of the conservationist, CA can be seen as beneficial because there is an effort to conserve what people use every day. Since agriculture is one of the most destructive forces against biodiversity, CA can change the way humans produce food and energy. With conservation come environmental benefits of CA. These benefits include less erosion possibilities, better wat…
As in any other business, producers and conservationists are always looking towards the future. In this case CA is a very important process to be looked at for future generation. There are many organizations that have been created to help educate and inform producers and conservationists in the world of CA. These organizations can help to inform, conduct research, and buy land in order to preserve animals and plants (New Standard 1992).
As much as conservation agriculture can benefit the world, there are some problems that come with it. There are many reasons why conservation agriculture cannot always be a win-win situation. Examples of these disadvantages include high initial costs of specialized planting equipment, and a new dynamic farming system that requires new management skills and a learning process by the farmer. Long term experience with conservation farming all over the wor…
