The soil is teeming with life. In a handful of dirt, you will find earthworms, centipedes, beetles, millions of fungi and bacteria, air and water. We truly know that good soil makes bigger and stronger plants. Most of the plant’s nourishment comes from the soil. When they have ample and the right amount of minerals and nutrients from the soil, plants are able to defend themselves from pests and diseases. This is because organic matter feeds the bacteria and fungi in the soil. The bacteria and fungi, in turn, break down the compost into compounds, and minerals, to small portions so the plants can absorb them. Thus, the more minerals and nutrients in the soil, the more the plant can take up.
However, improper farming practices have taken a toll on our planet’s soil. We only have thirty percent (30%) of farmable soil left in our planet. Thirty! Our soil is rapidly being depleted. Not only this, nature takes approximately five hundred (500) years to build one inch of top soil and a good crop yield takes an average of six inches of good top soil. How do we destroy our important resource? We lose or contaminate the soil by erosion, pollution, and through the voluminous use of artificial fertilizers, pesticides or herbicides. For example, in conventional farming, pests and disease are controlled with pesticides and herbicides. These chemicals kill the bacteria and fungi, which reduces the mineral content of the soil dramatically. To counteract this, they use a chemical fertilizer that contains only nitrogen, phosphorus and potassium – NPK. Plants can grow with these limited available minerals but they are less nutritious and far more susceptible to disease. It becomes a vicious cycle of more pesticides and more chemical fertilizers to sustain life. This method is especially absurd when you realize that the same effect can occur naturally on its own and provide us with a healthier outcome.
We need to recognize the fundamental role of soil in life and know that it is crucial that we maintain and develop our soil’s fertility. How do we respect the soil? Natural farming methods such as organic farming and biodynamic, when practiced sustainably, nourishes the soil more than it destroys it. Some of the methods we use at the farm for soil fertility are: (1) adding more nutrients to the soil through manure, compost and green waste; (2) suppressing the use of artificial fertilizers and pesticides; (3) composting through organic material; (4) using seaweed and fermented fish waste as foliar spray; (5) using legumes as cover crops. Cover crops protect the soil from wind, water and nutrient loss; and (5) crop rotation because different crops put in or take out different nutrients.
