Balancing Soil Using Organic Minerals
Soil Fertility Fertile soil is a mixture of well-balanced minerals, high organic matter, humus, humic, fulvic and carbonic acids, good aeration and bountiful soil life. The biology or life in the soil is at its healthiest when the nutrients are plentiful and balanced, and there is sufficient oxygen and water. The top few inches of soil is the most vital, holding about 70% of the life and 70% of the organic matter. Below 6 inches the roots are feeding on mostly soluble nutrients since the micro-organisms are not able to thrive without sufficient oxygen. It is possible to create biological activity deeper with deep double dug or mechanical disturbance like spading. Compost The best and cheapest organic fertilizer is compost. Taking a Soil Sample The aerobic zone is usually only 6-7” deep and should be all you need to sample for annual crops. Reading the Soil Test There are many labs around the country that give soil results. Organic Matter (O.M.) Phosphorus Potassium Magnesium Calcium Sodium pH C.
