Measuring soil carbon change
soilcarboncoalition.orgMuch of world agriculture has long depended on purchased inputs of nitrogen, potas-sium, and phosphorus. Carbon, the principal dry-weight constituent of crop residue and manure, has typically been regarded as a waste product and a disposal problem, to be dumped somewhere else, or burned.

Thus, control of tile drainage is important in reducing stream and ground-water nitrate concentrations. In addition, tile drainage changes soil chemistry, which
Phosphorus Fertilizer Production and Technology
www.ipni.netPhosphorus (P) Cycling in Crop Production Systems. Phosphorus is an essential element for all forms of life. Phosphorus in the earth’s crust is mostly contained in soils and sed\൩ments. Soils contain both organic and inorganic P containing compounds. Phosphorus reactions in soils can be quite complex.
