Weeds are often a problem people think can only be solved with herbicides. The fact is they are symptomatic of problems with your soil and using herbicides have many undesirable side effects by killing off beneficial microbes in your soil which leads to increased problems for any animals grazing the land. Nutrient balance in the soil is vital if one wants to discourage weed growth. Farmers can use the identity of the weeds that grow on their land to evaluate what is wrong with their soils. Broadleaf weeds, for example, generally present to correct an imbalanced ratio between phosphorous (P) and potassium (K). They are also a symptom of calcium deficiency. Succulents frequently point to soils deficient in the appropriate type of biologically active carbon. Weeds from the Crucifaerae family thrive in soils that have been subjected to the overuse of salty fertilizers such as potassium chloride. “Sandy, alkaline and badly drained soils all produce different kinds of weeds,” Graeme explains.
