A form of nitrogen which is readily available to both aquatic and terrestrial plants as a nutrient. The oxidation of ammonia to nitrate and nitrite, yielding energy for decomposing organisms. An element that is a component of protein structures in living organisms. The practice of leaving the soil undisturbed from harvest to planting except for nutrient injection. Planting or drilling is accomplished in a narrow seedbed or slot created by coulters, row cleaners, disk openers, in-row chisels, or rototillers.
Weed control is accomplished primarily with herbicides.
This may involve changing fertilizer application techniques, placement, rate, or timing. The term fertilizer includes both commercial fertilizers and manure. In water resources, if other physical and chemical conditions are optimal, excessive amounts of nutrients can lead to degradation of water quality by promoting excessive growth, accumulation, and subsequent decay of plants, especially algae. Some nutrients can be toxic to animals at high concentrations. Same as a live stream.
