In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure , crop planting, type and application rates of fertilizers , and other factors are taken into account to avoid excessive nutrient loss.
A nitrate vulnerable zone is a conservation designation of the Environment Agency for areas of land that drain into nitrate polluted waters, or waterways that could become polluted by nitrates due to environmental and health threats.
Nitrate may be lost from the soil to the atmosphere when bacteria metabolise it to the gases NH 3, N 2 and N 2 O, a process called denitrification. Nitrogen may also be leached from the vadose zone if in the form of nitrate, acting as a pollutant if it reaches the water table or flows over land , more especially in agricultural soils under high ...
Nitrification is important in agricultural systems, where fertilizer is often applied as ammonia. Conversion of this ammonia to nitrate increases nitrogen leaching because nitrate is more water-soluble than ammonia. Nitrification also plays an important role in the removal of nitrogen from municipal wastewater.
A saltpetre works or nitrary [1] is a place of production of potassium nitrate or saltpetre used primarily for the manufacture of gunpowder. The saltpeter occurs naturally in certain places like the "Caves of Salnitre" ( Collbató ) known since the Neolithic.
Climate-driven extreme weather conditions, such as droughts and intense precipitation, may be accelerating the pace at which toxic nitrates are polluting groundwater, a recent study has found.
Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent. [1] Leaching is a naturally occurring process which ...
Denitrification is a microbially facilitated process where nitrate ... Since denitrification can remove NO 3 −, reducing its leaching to groundwater, ...
