Variable Rate Technology 04/08/09 2:07:29 PM|
|VRT or Variable Rate Technology involves applying fertilizers at a variable rate rather than a constant rate. This allows you to place your nutrients where they are needed. This, in turn, will maximize your crop production, promote an even ripening and reduce lodging. This means that you get greater yields, and your overall crop quality will improve. By using VRT technology we can identify, analyze and manage the natural variability within your fields. This will allow you to fully tap the profit by field.|
Example: If a field of corn averages 150 bushels per acre, then maintenance fertilizer recommendations call for replacement of P and K removed by the crop across the whole field. In reality, fields have a wide range of yield (for example, from 90-210 bu./ac). Using soil type zone testing, you can eliminate over fertilizing the lower producing soil types and place more fertilizer in the higher producing soil types, thus you would have your VRT.
Can VRT save me money?
It is best to see VRT as a profit generating tool, creating better efficiencies at the front end in order to produce highter yields at the back end. It is possible that your input costs could drop, however, in order to get the highest return on investment it is usually recommended that what is saved in one zone be invested in another. One of the most appealing features of VRT is the ability to make these decisions based on a given set of factors.
