Nutrient Management

Advantages:
Overview:

Nutrient management is perhaps the most time consuming planning part for an upcoming cropping season. It is also one of the most important, whether you are thinking about using a starter fertilizer, placement of that starter, or what form of N will be used. These decisions often significantly impact your ability to meet your yield goal. Any nutrient management plan should be based off of a good soil testing program whether it is grid-based or management zone based.

There are two main options for producers in regards to P and K, depending on circumstances for specific producers, fields and situations. ‘Sufficiency’ fertility programs are intended to estimate the long-term average amount of fertilizer phosphorus required to, on the average, provide optimum economic return in the year of nutrient application. In some years greater amounts of nutrient are required for optimum yield and economic return, while in other years less than recommended amounts of nutrient would suffice.

There is little consideration of future soil test values and soil test values will likely stabilize in the ‘low’, crop responsive range. ‘Build-maintenance’ recommendations are intended to apply enough phosphorus or potassium to build soil test values to a target soil test value over a planned timeframe (typically 4 to 8 years) and then maintain soil test values in a target range in future years.  Build-maintenance fertility programs are not intended to provide optimum economic returns in a given year, but rather attempt to minimize the probability of phosphorus or potassium limiting crop yields while providing for near maximum yield potential.

What you receive:

You will receive a detailed plan that outlines a “total fertility” package for your field. This will include steps to take to correct all deficiencies and increase nutrient use efficiency in order to get the biggest bang for your buck as possible. Specifics included in the plan:
