About Organic Fertilizers and Soil Amendments

First, a few words about chemical fertilizers... Fertilization with high concentrations of Nitrogen, Potassium, and/or Phosphorus (N-P-K such as 15-15-15 or 20-20-20), stimulates rapid initial plant uptake of trace minerals (also known as trace elements) without providing for their replacement. It is common knowledge that excessive nitrogen reduces the valuable calcium available to the plant. Calcium is a "cation", together with Magnesium, Potassium, and Sodium. A reduction in the available Calcium, always leads to an imbalance in the "cation exchange". If cations are out of balance, anions will also not work properly, nor will several important trace elements.   The question now is no longer whether to re-mineralize, but where to get the best universal rock dust. Excessive Nitrogen use is also leading to a "tightening" of vast amounts of soil on agricultural land. Additionally, a mostly unknown fact is that the carrier materials for chemical fertilizers can be sewage sludge, and sludge represents about 80% of the weight of that fertilizer. This type of granulated fertilizer is commonly used for lawns and turfs. Liquid fertilizer, which is widely used in commercial agriculture, is causing the leaching of a large amount of N-P-K into the ground. This is one of the most serious environmental problems we have today. The government will soon require water run-off impact permits if this problem isn't dealt with by industry and consumers. For some time, researchers, using fairly coarse rock dust (the only kind available to them) have tried to justify the remineralization of the soil with rock dust. The question now is no longer whether to re-mineralize, but where to get the best universal rock dust.
