Little River, TX | You have a point as long as your soil is a neutral Ph or not a heavy clay.
All this presupposes the operation is done properly, and not leave an open slit behind the strip till fertilizer application.
If the soil is strongly acid or alkaline then phosphate will be tied up as an aluminum or calcium complex. In that case the less fertilizer that is outnumbered by the soil will be delayed in the tie up process.
Up in Oklahoma they did some work on phosphate fertilization for alfalfa. The short answer was the total alfalfa production was greater with putting out 6 years supply of phosphate than annual or biannual applications. Then they deep banded 6 years worth of 10-34-0 on 20 inch centers and the improved production more than paid the increased cost. In talking with one of the Oklahoma people I find using 30 inch centers would be even better but the equipment they borrowed was on 20 inch centers. | |
