METHANE RECOVERY FROM ANIMAL MANURES: THE CURRENT OPPORTUNITIES CASEBOOK Because it is low in volatile fatty acids and does not stick to the leaves, filtrate can be spread on growing plants (e.g., on corn as tall as 20 inches) with only minor risk of burning. As a result, the chance for atmospheric emissions will be even further reduced when filtrate is spread on growing plants. Additionally, legumes such as clover and soybeans have root-dwelling bacteria on them that fix nitrogen. However, raw undigested manures spread on the ground make clover clump into small tight patches in grassland. By digesting manure, the acidic nature of the manure is reduced and clover runs root to root with the grass giving more opportunity for grass to be fed 36 By using AD, it is possible to greatly reduce the use of traditional nutrients in 37 soils. One study using data from the People’s Republic of China reported 6%-20% greater yields using digester effluent to meet crop nutrient requirements. Additional research in the United States is necessary to better document the added availability of nutrients from digested organic residues. This is especially true when much of the current bioenergy focus in this county has the goal to develop and demonstrate environmentally acceptable energy crops and cropping systems for producing large quantities of low-cost, high-quality biomass feedstocks. AD can enrich alternative agricultural practices when the digestion residues are applied to energy crops and other dedicated feedstocks for the production of alternative fuels such as biodiesel or atmospheric nitrogen via the clover’s underground nitrogen-fixing bacteria. Recycling digested nutrients on energy crops like this harvested switchgrass can help create a virtuous cycle of sustainability (photo credit: Oak Ridge National Laboratory) ethanol. Treating commodities to produce another energy yield while recycling nutrients creates a virtuous cycle of sustainability. 2.6 Odor, Pathogens, and Anaerobic Digestion Odor from animal manures has become regarded as a nuisance in almost every state in the union. Although odorants are usually present at levels far below those considered to be toxic 36 Northern Ireland. Gornall, L. (3 April 1998). Personal communication.
