The weight a soil can withstand before severe damage occurs to the structure of the soil. Bearing capacity varies throughout the year, based upon the moisture content of the soil. For instance a very heavy tractor that causes no damage on dry soils may cause a lot of damage to the soil structure of wetted [...]
Total amount of water in the root zone that is available for evapotranspiration, usually expressed in mm.
Underground reserve of freshwater usually contained in a discrete layer of water-permeable rock or other material (such as gravel, sand etc.) from which water can be extracted using a well or other appropriate extraction technology.
Synthetic biocide directed at destroying insects, nematodes, molluscs, mammals, plants, fungi or bacteria.
The use of machines to bury, cut or uproot the weeds.
The use of biological agents (intact organisms, components derived from organisms) to destroy or deter pests and diseases or to promote natural enemies.
A crop grown under a nurse crop and intended to become either a non-harvested crop grown in between two main crop seasons or become a main crop itself in a next season.
The process whereby plants lose water by evaporation of liquid water at the surface of the stomatal cells, the water vapour diffusing out through the leaf via the stomata openings.
Growing crops in a systematic arrangement of strips or bands which provide vegetative barriers to wind and water erosion.
The extent to which a soil is covered (in space and/or time) by a vegetation, including crops, or dead crop residues on the surface of the soil, directed at reducing soil erosion and the loss of particulate pollutants (i.e. those attached to soil) including nutrients, plant protection products and fecal microbes. Measures directed at increasing [...]
