Natural topsoil is mined and conditioned for human use and makes up the bulk of commercial topsoil available. The current rate of use and erosion outpaces soil generation. [4] It is possible to create artificial topsoil which supports some of the engineering or biological uses of topsoil. [4]
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.
Regenerative agriculture uses traditional farming practices developed by Native Americans, such as avoiding or reducing soil tillage, using livestock, diversifying crops, and planting cover crops ...
Agricultural machinery – machinery used in the operation of an agricultural area or farm. Fertilizers – any organic or inorganic material of natural or synthetic origin (other than liming materials) that is added to a soil to supply one or more plant nutrients essential to the growth of plants.
Permaculture (from "permanent" and "agriculture") is a type of conservation agriculture, which is a systems thinking approach that seeks to increase the carbon content of soil by utilizing natural patterns and processes. There is a strong emphasis on knowledge of plants, animals, and natural cycles to promote high-efficiency food production ...
Soil compaction causes reductions in crop growth, yield and quality. Locally, these effects may have minor impacts on food security. If one aggregates the losses in food supply due to soil compaction, however, compaction may threaten food security. This is especially relevant for regions that are prone to droughts and floodings.
In food distribution, increasing food supply is a production problem, as it takes time for products to get marketed, and as they wait to get distributed the food goes to waste. Despite the fact that throughout all food production an estimated 20-30% of food is wasted, there have been efforts to combat this issue, such as campaigns conducted to ...
The Food and Agriculture Organization of the United Nations (FAO) estimates world demand for nitrogen fertilizers increased by 1.7% annually between 2011 and 2015, an increase of 7.5 million tonnes. Regional increases of nitrogen fertilizer use are expected to be 67% by Asia, 18% by the Americas, 10% by Europe, 3% by Africa, and 1% by Oceania. [5]
