Strip-Till Vs. Broadcast Trial
This trial was designed to demonstrate the benefit of nutrient replacement. Roots move down by gravity and temperature and when nutrients are placed directly below the seed the likelihood of them accessing the nutrients is much more than it would be in broadcast. This precision placement of nutrients will also result in better nutrient use efficiencies. Both replications demonstrated that precision
nutrient placement with strip-till produced more yield than the same nutrients when applied by broadcast application. For the only strip-till treatment, nutrients were applied with the strip-till applicator. For the broadcast treatment, the strip- till unit was ran to address compaction and did not apply nutrients. The nutrients were applied with the dry spreader for the broadcast section of the treatment. This study had similar results to trials that Orthman has conducted around the globe. The data from this trial demonstrated an advantage of R3588/ha using strip-till over broadcast fertilizer application.
