Document Summary
Piles: if you can"t spread on the land (due to frozen ground or snow-cover) Leave in a barn: depends on the type of farm (ex. at dairy farm you don"t want to leave the manure with the cows) Lagoons: anaerobic and generally not the best option. Keeps livestock comfortable: also absorbs urine and the nutrients that come with it. Composting kills bacteria and diseases: if the compost is still high in bedding and it"s not broken down correctly then you cannot apply it to the land according to organic certi cation. Keep in mind april 15th is approximately two weeks before planting typically occurs. Over application (per year: 20 tons per acre = for nutrients, 30 tons per acre = for increasing organic matter content. Neither of the above are polluting: disposal -> 40-100 tons per acre = polluting. > 100-300+ = ne, there"s less pollution problems due to microorganisms and nitri cation.
