Book excerpt: Humusphere by Herwig Pommeresche

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 […]

Building the Microbial Bridge to Support Nutrient Availability

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 […]
