Agricultural soil science studies the chemical, physical, biological, and mineralogical composition of soils as they relate to agriculture. Agricultural soil scientists develop methods that will improve the use of soil and increase the production of food and fiber crops. Emphasis continues to grow on the importance of soil sustainability.
A semi-wild area, mainly used for forage and collecting wild plants as well as production of timber for construction or firewood. [33] Zone 5 A wilderness area. Humans do not intervene in zone 5 apart from observing natural ecosystems and cycles. This zone hosts a natural reserve of bacteria, molds, and insects that can aid the zones above it ...
Plant and Soil is a monthly peer-reviewed scientific journal covering research on the relationships between plants and soil, such as relationships and interactions of plants with minerals, water and microbes, the anatomy and morphology of roots, soil biology and ecology, etc.
The Food and Agricultural Organization of the United Nations (FAO) uses good agricultural practice as a collection of principles applying to on-farm production and post-production processes, resulting in safe and healthy food and non-food agricultural products, while taking into account economical, social and environmental sustainability.
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.
Cognisant of agriculture's role in the economy, the 11th five-year economic plan that runs from 2007 to 2012 recognises the importance of proper soil management in agriculture. Soil degradation through excessive and miscalculated fertiliser use because of emphasis on increased output has led to nearly two-thirds of India's farmlands to be ...
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 ...
Soil that was removed and stockpiled (e.g. during the operation of a mine), can become part of a constructed soil once a site is being reclaimed. [4] The goal in designing a constructed soil is to replicate the physical, chemical, and biological functions of natural soils. The target soil properties depend on the site location and final land use.
