Improve biological properties of soil

Biological Properties Soil

Improving soil physical and chemical properties is important for both conventional and organic production, but improving biological properties is particularly important for organic production. Producers describe soil biological health in terms of earthy smell, soil crumbliness, and greasy feel. Soil scientists measure soil biological health in terms of microbial biomass, microbial communities, and rate of organic matter decomposition. Organic production relies on nutrients released through the...

Management of crop nutrients and soil fertility

Organic soil fertility management is based on feeding the soil a rich, complex diet of plant residues, animal manures, and compost. In contrast, conventional agriculture simplifies crop nutrient and soil fertility management by feeding the plant soluble nutrients. Thus, crop nutrition in conventional agriculture can be managed with three pieces of information 1 the amounts of nutrients used by the crop during the growing season, 2 the amount of plant-available nutrients in the soil, and 3 the...
