When using organic amendments, make sure that they have not been treated with herbicides, as it can carry over into the soil. Inorganic amendments include pumice, perlite, vermiculite and sand.
A new study overturns assumptions about how phosphorus becomes available in soils and sediments for plant growth.
Its website states that arsenic is "a naturally occurring element in soil and water" and "all plants take up arsenic." But "natural" does not equal safe. Inorganic arsenic, the predominant form of ...
Northwestern researchers made progress on new biochemical possibilities this week, in both the human brain and everyday ...
Of this amount, nearly 80% (2500 GT) is found in soil (Lal 2008). Soil carbon can be either organic (1550 GT) or inorganic carbon (950 GT). The latter consists of elemental carbon and carbonate ...
Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that ...
Plants and microbes are known to secrete enzymes to transform organic phosphorus into bioavailable inorganic phosphorus. Now, researchers report iron oxides can drive the same conversion at comparable ...
A critical nutrient for life, most phosphorus in the soil is organic—from remains of plants, microbes or animals. But plants need inorganic phosphorus—the type found in fertilizers—for food.
