In this breakthrough work — now available in English for the first time — the independent German-Norwegian explorer of soil life, graduate permaculture designer and graduate engineer Herwig Pommeresche shares his lifetime of research into humus.
His entire career has focused on the theory and practice of humus management in gardening and farming. Digging deep into a myriad of little-known research papers, he compares their findings with the usual conventional methods.
He found we have an inadequate understanding of the mechanisms by which plants absorb and process their nutrients. Our conventional model is that plants only get nutrients in the form of water-soluble salts, hence common conventional fertilizers. Fertilization methods in agriculture and horticulture have been based on this model, which the author calls “mineral model,” since the mid-nineteenth century. They largely have not been questioned since then despite the problems they cause. FREE – SHOP NOW /
