FNi'trogen Balance: Nitrogen required at fields 256,517 lbs.N Nltrngen from liquids: 121,22$ Abs,N 9 Nitrogen shortage from liquids: 135,289lbs.-N Nitrogen from solids: 96,654 lbs.N f Nitrogen shortage: 36,635 !bs:N. } FNitrogen Loading Conclusion The current farming operation is adequate to consume all the nitrogen contained in the liquids and solids generated at the site. FD As ln&cated in the calculations above,the remaining nitrogen that will be in liquids and solids after storage losses ih the flush agoon are fewer than the calculated nitrogen demand from the proposed farming acreage. Composting of the manure solids will condition thesolids prior to application to the farm. n Composting converts an organic waste material into a stable organic product by converting nitrogen tram the unstable ammonia formto a more stable organic form.The end result is a product that is safer to use than raw organic Material'. Fri Composting can reduce the nitrate content of the solids due to anaerobic bacterial activity.Anaerobic activity will cause deniffication of nitrate to convert the nitrates to the gaseous form as nitrous oxide or nitrogen gas during the composting process. FFF Thisigas 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 time which is the point at which aerobic bacterial activity has oonsuroed all the Foxygen with in the mix n Manure i,more carbonsaous than commercial fertilizer and carbon is a common energy source to bacteria.Consequently,some denitification will also take place in the soil naturally. Q Compost is used primarily as a fertilizer supplement and soil conditioner.Compost improves soil structure and fertility.Nutrients in tnioed compost will be slowly released aver a period of years,thus minimizing the risk of nitrate leaching and high nutrient - corieentrations in surface runoff. 7 A balancad tiquids/soiids application rates are favorable to the agronomical management of the soil because of the soil requiring organic materials to increase With,water intake rate,watef retention capabilities and consequently,nitrate retention capability. ❑It is important to apply nutrients through out the growing season as the crop requires it. ❑The lagoori water needs to be managed in such a fashion that the irrigation pond is empty prior to the wintevrainfall 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 row water holding capacity of tfie farms'soils. Fi 3 I` �f y Fj 1 Fr ._ F.1
