Intensive farming methods to satisfy high food demands with high crop yields and growing crops in monocultures can deplete the soil nutrients and damage the soil microbiome. These factors can affect the consistency and quality of the soil resulting in increased erosion. Surface runoff from farm fields is a type of nonpoint source pollution.
Chernozem (/ ˈ tʃ ɜːr n ə z ɛ m / CHUR-nə-zem), [a] also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus [3] (4% to 16%) and high percentages of phosphorus and ammonia compounds. [4] Chernozem is very fertile soil and can produce high agricultural yields with its high ...
Finding that they did not approve of dunging their vineyards, Tull readily adduced the fact in favour of his own favourite theory: that manuring soil is an unnecessary operation. [2] Returning to England, in 1709 he took into his own hands the farm called Prosperous, at Shalbourne [ 3 ] (then in Berkshire, now in Wiltshire).
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.
The use of artifices does not make the land arable. Rock still remains rock, and shallow – less than 6 feet (1.8 metres) – turnable soil is still not considered toilable. The use of artifice is an open-air non-recycled water hydroponics relationship.
The best way to determine if the soil is acidic or deficient in calcium or magnesium is with a soil test which a university can provide with an agricultural education department for under $30.00 for United States residents. [8] Farmers typically become interested in soil testing when they notice a decrease in crop response to applied fertilizer.

Some soil variables of special interest to agricultural soil science are Soil texture or soil composition: Soils are composed of solid particles of various sizes. In decreasing order, these particles are sand, silt and clay. Every soil can be classified according to the relative percentage of sand, silt and clay it contains.
