Is organic fertilizer the answer?
While the nutrients in organic fertilizers such as animal manure are from natural sources, and may be at lower concentrations than synthetic fertilizers, they are still chemical elements that impact the environment. The nitrogen, phosphorus, and potassium enter the soil where they are added and inevitably become a part of that particular ecosystem.
While waste is a natural component of the life cycle, humans exploiting animals for their own resources has a larger environmental impact than wild animals living, consuming, and defecating naturally without human intervention.

I have come to the realization that fertilizer has a negative impact on the environment whether it is organic or not. Synthetic fertilizers have more chemicals in them and I believe that they impact the environment to a harsher extent than organic fertilizers. I have started to question the relationship between inorganic fertilizers and pesticide use. I assume that people who use synthetic fertilizers are more likely to use pesticides and I am curious to find out whether this is true. I am also interested in learning about the impact that pesticides have on the environment and on the foods that they are used on. In general this research has increased my curiosity about horticulture and agricultural practices and has reaffirmed my belief that everything is interconnected in the environment.

I have come to the conclusion that that if your soil requires nutritional intervention it is best to go as organic as possible. It is impossible to eliminate human impact on the environment, but we can do our best to minimize and control our footprint.
