Soybean production factors out as follows: a 50-bushel crop takes 280 pounds of nitrogen.
It is a big mistake to consider that just adding enough fertilizer to grow the crop is what determines soil fertility.
Herwig Pommeresche, a German-Norwegian explorer of soil life, graduate permaculture designer and graduate engineer, shares his lifetime of research into humus. Humusphere, translated into English for the first time, digs deep into a myriad of little-known research papers, comparing their findings with the usual conventional methods. Herwig Pommeresche offers an ecologically oriented understanding as a check to the […]
It’s strange to think that plants have a hard time getting enough nutrients when soils are composed of around 45 percent minerals. Many of those minerals are the nutrients plants need to grow, photosynthesize, flower, pollinate and produce fruit or seeds. Although soil is a huge bank of minerals, most of those minerals are not […]

Soil fertility in turn is related to the growth and reproduction of soil organisms and to the plants that grow in the soil. In due process this affects the health, well-being and fertility of the animals and humans […]
