rwitreEjen Balance: Nittogen required at fields lr�Nitrogen liquids: 258,2'7lbs. N Nitrogen shortage from liquids: 95,381 lbs.N •Nitrogen from solids: 162,837 lbs.N k 77,766_ lbs.N 1 [Nitrogen shortage! 85,070 lbs:N Nitrogen Loading Concitusion The Current farming operation is adequate to consume all the nitrogen contained in the liquids and solids generated at the site. rAs indicated in the calculations above,the remaining I g nitr Ogen that will be in liquids and solids after storage losses in the flush agoon are fewer than the tabulated nitrogen demand from the proposed farming acreage. ,'3 Composting of the manure solids will condition the solids prior to application to the farm. - 0 Composting converts an organic waste material into a stable organic product by converting nitrogen from the unstable ammonia form to a more stable'o anic form,The .al. r9 end result is a product that is safer to use than raw organic material. ]Composting can reduce the nitrate content of the solids due to anaerobic bacterial activity-Anaerobic act{vitt'wit!cause denitification of nitrate to convert the nitrates to the gaseous form as nitrous azide or nitrogen gas during the composting process. rhis gas then escapes into the atmosphere.Considering that composting is an aerobic activity,anaerobic activity can be controlled by - - simply turning the material to aerate it at the proper tfine which is the point at which aerobic bacterial activity has consumed all the oxygen with in the mix 17 Manure is more carbonaceous than commercial fertilizer and carbon Is a common energy source to bacteria.Consequently,some .ionitiflcation will also take place in the scH naturally. 11 Compost is used primarily as a fertilizer supplement and soil conditioner.Compost improves soil structure and fertility.Nutrients in nished compost will be slowly released over a period of years,thus minimizing the risk of nitrate leaching and high nutrient 1bg concentrations in surface runoff. I A balanced liquidsisolids application rates are favorable to the agronomical management of the sail because of the soil requiring 'organic materials to increase tilth,water intake rate,water retention capabllltles and consequently,nitrate retention capability, 0 It is important to apply nutrients through out the growing season as the trop requires it. 7 The lagoon water needs to be managed{n such a fashion that the irrigation pond is empty prior to the winter rainfall season,yet not applying nutrients to the crops when they are not needed. - Over irrigation needs to be at a minimum for nitrates can be pushed through the soil profile due to the low water holding capacity of the farms'sot's.
