In the past I’ve applied my starter in a 2x2 application. Will I get the same results by dribbling my starter fertilizer? I plan on applying the starter (30-30-0-5) on the soil surface as a band a couple inches from the seed trench.
Posted on April 4, 2011W. Barney Gordon, Ph.D., M.S.
Research studies in north central Kansas and in Iowa indicate dribbling starter fertilizer next to the seed row is as effective as 2x2 applications. Low volume application (five gallons/acre or less) may not be as effective, but the volume necessary to make a 30-30-0-5 starter should be adequate to achieve good results with surface applied starter.
My wheat crop looks great, but I'm concerned about harvesting high yields with low protein; I need at least 14 percent protein to maintain profits. Will late applications of nitrogen increase protein, and when is the best time to apply to manage protein levels?Larry Murphy, Ph.D.
Depending on wheat yield and total nitrogen availability for the crop, late N applications often will help boost protein content. Adequate N must be available throughout the growing season in order to maximize yield and grain protein content. The first step in achieving high wheat grain protein is to ensure an adequate fertility program (especially N) for expected yield. Late N… Read Full Answer
How late this year can I apply AVAIL-treated phosphate fertilizer to my bermuda grass and still get benefit?Dale Leikam, Ph.D.
Forage (Bermuda) grasses are very good surface feeders due to the large root mass immediately under the soil surface. In order for surface-applied phosphorus to benefit grasses, however, soil needs to be moist at the surface/thatch interface, so root uptake can occur. The best time to apply Phosphate fertilizer is right before the grass undergoes rapid growth (dry matter accumulation)… Read Full Answer
