Some fertilizer formulations
Organic Fertilizer #1 - Costs same as NPK fertilizer per N in 50# quantities, and is slow release over time and provides many additional micronutrients and phyto-compounds as well as builds soil and increases structure and porosity over time. In our operations, we ferment the ingredients together and then blend into the compost and allow it to age for a few weeks before applying to the soil. It's non-burning, but the fermentation process makes the nutrients available to the plants much quicker. There is some possibility that some of the nitrogen may be releasing into the atmosphere during the fermentation process. I am still learning about the nitrogen cycle and how nitrogen behaves during the fermentation process.

Fertilizer Summary
Solubility of chemical fertilizers and specific control over nutrient content is a real advantage in many situations compared with natural fertilizers and soil amendments which may provide higher quality nutrition, but without control over time-availability. On a farm, with actual soil, my preference is to apply manures and agricultural residues, perhaps with some fermentation before application to speed availability and prevent negative types of biological activity like molding and creation of rancidity or other noxious odors while the residues are decaying. Even a short soaking in innoculant before application can speed nutrient availability and significantly reduce possibility of negative biological activity.I've been working with food wastes, developing processes for decaying them and applying them without odors, but there is definitely a stigma associated with their processing. Store owners look at me like I'm insane when I tell them that I want their garbage. There's a lot of labor associated with separating them from the garbage stream and processing them safely, and it's just so much cheaper to purchase agricultural residues like soybean meal or cottonseed meal. Agricultural residues are also generally more nutritious for the soil and provide a more balanced nutritional profile.
I am learning a lot about biological processes and how they effect microorganisms while learning about algae production. One of my goals is to produce algae for livestock feed using composted waste products as a nutrient source. There is a lot of labor involved, but it seems like a viable process. I am also learning a lot about porosity and filtration techniques used to prepare the effluent since clarity effects the ability of light to penetrate to all the individual cells of algae, which in turn has an effect on production density, or the ability to achieve a high density of algae.
