Biological farming does not mean less production; it means eliminating obstacles to healthy, efficient production. It is a safe and sustainable system designed to keep production up. Once the chemical, physical and biological properties of the soil are in balance, you can expect optimal outputs, even in bad years. Biological farming improves the environment, reduces erosion, reduces disease and insect problems, and alters weed pressure - and it accomplishes this by working in harmony with nature. Skilled biological farmers learn how to take care of soil life - they nurture it, feed it a blanced diet, and use tillage tools and methods to enhance soil life. Biological farmers learn proper fertilizer uses to correct mineral and nutrient imbalances to feed plants and soil life.
