Nitrogen Loading Conclusion - Phase IV • The current farming operation is adequate to consume all the nitrogen contained in the liquids and solids generated at the site if agronomical procedures and application practices are followed based on double cropping farmed fields. • As indicated in the calculations, the remaining nitrogen that will be in liquids and solids after storage losses in the flush lagoon, irrigation pond, and corrals are fewer than the calculated nitrogen demand from the proposed farming acreage. • Composting converts an organic waste material into a stable organic product by converting nitrogen from the unstable ammonia form to a more stable organic form. The end result is a product that is safer to use than raw organic material. I' • Considering that the ability to slow the leaching of nitrates through the soil profile, the application of organic materials to build the water holding capacity and tilth of the lolls at the site is necessary. k: Composting of the manure solids will condition the solids prior to application to 1 the farm. E Composted manure is safer to use than raw organic material. Composting can reduce the nitrate content of the solids due to anaerobic bacterial activity. Caution will be taken �o prevent anaerobic activity that will cause denitification of nitrate and convert the nitrates to the gaseous form as nitrous oxide or nitrogen gas during the composting process. This gas then escapes I' into the atmosphere which is not a desired result. Considering that composting is an aerobic activity, anaerobic activity can be controlled by simply turning the material to aerate it at the proper time at which aerobic bacterial activity has consumed all the available oxygen;,with in the mix. Compost is used primarily as a fertilizer supplement and soil conditioner. ' Compost improves soil structure and fertility. Nutrients in finished compost will be slowly released over a period of years, thus minimizing the risk of nitrate leaching and high nutrient concentrations in surface runoff.
