Nitrate-N and Manure Nitrogen Index NH4-N, whether applied directly or from the mineralization of organic-N, is further converted to nitrate-N (NO3-N) by microbial action in the soil. This process occurs rapidly (weeks) during the growing season. Unlike NH4-N, which will adhere to soil particles, the nitrate ion can move freely with soil water. Loss of … Continue reading Environmental Considerations with Manure (Organic Amendments) […]
