Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance (i.e. no-till farming), maintenance of a permanent soil cover, and diversification of plant species.
Soil-conservation farming involves no-till farming, "green manures" and other soil-enhancing practices which make it hard for the soils to be equalized. Such farming methods attempt to mimic the biology of barren lands. They can revive damaged soil, minimize erosion, encourage plant growth, eliminate the use of nitrogen fertilizer or fungicide ...
Conservation agriculture has three main practices: minimizing soil disturbance, maintaining permanent soil coverage, and diversifying crop species. [14] Similarly, regenerative agriculture practices use minimal to no tillage, cover crops, crop rotations, compost, and grazing. [15]
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
The Conservation Reserve Program (CRP) is a cost-share and rental payment program of the United States Department of Agriculture (USDA). Under the program, the government pays farmers to take certain agriculturally used croplands out of production and convert them to vegetative cover, such as cultivated or native bunchgrasses and grasslands, wildlife and pollinators food and shelter plantings ...
Minimum tillage is a soil conservation system like strip-till with the goal of minimum soil manipulation necessary for a successful crop production.It is a tillage method that does not turn the soil over, in contrast to intensive tillage, which changes the soil structure using ploughs.
Modification of agricultural practices is a recognized method of carbon sequestration as soil can act as an effective carbon sink. [58] Soil management techniques include no-till farming, keyline design and windbreaks to reduce wind erosion, reincorporation of organic matter into the soil, reducing soil salinization, and preventing water run ...
The Soil Conservation Service worked with state governments and universities with established agriculture programs, such as the University of Nebraska, to promote the method to farmers. By 1938, the introduction of new agricultural techniques, such as contour plowing, had reduced soil loss by 65% despite the continuation of the drought.
