Sulfur and nitrogen are an important component of crop production. They often come from multiple sources and can be lost to the environment or immobilized during decomposition. Accounting for all sources of these nutrients can improve farm profitability by reducing application needs or accounting for shortfalls with additional commercial fertilizer. Although the release of some sources of these nutrients are harder to predict than others. Currently, the corn nitrogen rate calculator has the most profitable nitrogen rate based on a nitrogen price of $0.70 per pound and corn price of $5.50 per bushel ranging from 156 to 182 pounds of nitrogen per acre.
Nitrogen availability from manure
Manure is an excellent source of nitrogen but the way it is applied greatly affects how much of the manure test nitrogen will be plant available. When liquid or solid manure is incorporated at application or shortly after for a pre-plant or sidedress application 95% of the Ammonium-N will be available for this year’s crop.… Continue readingRead More »
