Its well known that fertilizers are analyzed on the basis of their value of Nitrogen, Phosphorus and Potassium or Potash (N-P-K). They provide and enhance nutrient sources for the plant, but the difference between the two lies in the benefits to the soil itself. Some of the downfalls of using fertilizer is how hard it can be on the soil health, how much of it gets washed away by water and deposited to water bodies like rivers or lakes, and how it’s effectiveness is compromised in sub-optimal soil conditions. Over time the chemicals and overuse of fertilizer can take its toll on soil. So what can we do to improve soil for grass or gardens if this is the case?
