Over twenty years ago Sir Albert Howard insisted on the importance of the biological, as distinct from the chemical, assessment of soil fertility. He declared that chemical soil analysis was, at very best, nothing more than a rough guide, to be checked against physical examination and a close observation of biological and botanical indications.
Learn what humus is and why it’s essential to your farm – whether you grow crops or livestock. Humus is formed by the relationships between organic life forms like microbes and other organic and inorganic elements in the soil, like minerals and nutrients.
The proportion of minerals has increased in cultivated soils during our era in comparison with past eras in which consistently humid heat promoted the formation of organic soil material over huge swaths of forest for thousands of years. The ratio between the organic and mineral portions of the material has shifted, to the detriment of […]
All any farmer really wants is the best uptake of plant nutrients for his or her crops. In order to make sure crops efficiently uptake all they need, crop expert Esper K. Chandler says, “We have to reestablish the humus function of the soil, the basis for natural/organic sustainable farming.” And this means putting water […]
Carbon is an often overlooked, but very important component of the soil. We know how to manage nitrogen, phosphorus and potassium for maximum production, and that micronutrients play a critical role in crop yield and disease resistance. Deficiencies can usually be corrected relatively quickly through the addition of soil or foliar fertilizer applications. While soil […]
It is a big mistake to consider that just adding enough fertilizer to grow the crop is what determines soil fertility.
The abundance of the earth is made possible by just a few elements, and the primary ones are free. Carbon, hydrogen, oxygen and nitrogen are everywhere, in air and rain. I have really good news. We know how to grow food without hurting the land, air or water, in a way that is good for […]
