Since only inorganic forms of nitrogen and phosphorus are available to plants, only a portion of the total nutrients can be utilized in the year of application. This can be advantageous for the crop because not all of the nutrients from manure are immediately available. The slow release of nutrients minimizes possible crop damage and prevents excess nutrients from being lost before plant uptake occurs. 2 O 5 as a starter fertilizer with the seed. Check the fertilizer recommendations of specific crops for any seed placed fertilizer restrictions.
Organic nitrogen is determined by the difference between total nitrogen and ammonia nitrogen.
Soil testing should be conducted to confirm the actual amount of available nitrogen in any specific situation. In some cases, it may be necessary to add a starter fertilizer to ensure the crop has enough nutrients available during its early growth stages. Volatilization of ammonia represents a significant means of nitrogen loss. 25-35 broadcast, immediate incorp. 15-25 broadcast, no incorp.
