A farming practice which attempts to manage and reduce the damage done to cultivated soils by repeated passes of heavy agricultural machinery such as tractors over the same area of land, particularly soil compaction, which often has negative consequences for numerous aspects of crop production. controlled-environment agriculture (CEA)
The word "cultivation" has several senses that overlap substantially with those of "tillage". In a general context, both can refer to agriculture. Within agriculture, both can refer to any kind of soil agitation.
Soil is used in agriculture, where it serves as the anchor and primary nutrient base for plants. The types of soil and available moisture determine the species of plants that can be cultivated. Agricultural soil science was the primeval domain of soil knowledge, long time before the advent of pedology in the 19th century.
Shifting cultivation (or slash and burn) is a system in which forests are burnt, releasing nutrients to support cultivation of annual and then perennial crops for a period of several years. [144] Then the plot is left fallow to regrow forest, and the farmer moves to a new plot, returning after many more years (10–20).
No-till farming is a soil conservation practice used in the United States, with adoption increasing due to its potential to reduce costs and improve soil health. By minimizing soil disturbance, no-till farming reduces the number of passes required with machinery, leading to lower fuel and labor expenses.
Soil depletion occurs when the components which contribute to fertility are removed and not replaced, and the conditions which support soil's fertility are not maintained. This leads to poor crop yields. In agriculture, depletion can be due to excessively intense cultivation and inadequate soil management.
(In cultivated soils the thickness of the hardsetting horizon is frequently equal to or greater than that of the cultivated layer.) Hardsetting soil is not permanently cemented and is soft when wet. The clods in a hardsetting horizon that has been cultivated will partially or totally disintegrate upon wetting. If the soil has been sufficiently ...
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.
