Background - Scientific Crop Agronomy, Inc. has been heavily involved in the agronomy service industry for over 15 years in central Nebraska. We pride ourselves in discovering, testing and applying safe and economic ways to promote soil/plant health and bringing proven products/practices to mainstream agriculture. We have successfully improved yields and increased soil health with countless customers over thousands of acres with both products and practices we have tested over the years.
The Goal of the Test - Our goal with this test was to see if there were any significant benefits of applying AgPhRx through the center pivot irrigation system. This test would focus on two crops; corn and soybeans. As agronomists we were looking for agronomic benefits including (but not limited to) the following: plant vigor, canopy height/coverage, mid to late season plant health, grain quality and overall yield throughout the growing season. We would then compare the findings and results with the control area.
Test Protocol - We recommended 16 ounce passes three times throughout the growing season at particular growth stages of both the corn and soybeans. On the corn we applied the first pass at V7 (7-Leaf), second at V18 (Pre-Tassel), and the final pass at R2 (Mid-Milk). On the soybeans we applied the first pass at V3 (3-Trifoliolate), second at R1 (Flower), and the final pass at R3 (Early Pod). In total we used 48 ounces of AgPhRx per acre on both the corn and soybeans. The control area that we selected was a “pie-shaped” flagged area on the corn soybean border. We shut the injection pump down between the flags on every pass of AgPhRx.
Test Field Information:
Corn - Overall plant health (especially after the second pass of AgPhRx) began to separate out shortly after full canopy though V16. The plant height of the treated areas were an average of 6-8” taller at beginning tassel than the control. Also the plant color/health was noticeably better in the acres with the full rate of AgPhRx. The corn yielded on average 10.74 bushel better than the corn in the control area over the scale. The ears seemed to be retained better on the treated areas with the late October winds vs. the control. We did not observe any noticeable difference in grain quality.
Soybeans - There was no true height separation on the soybeans throughout the growing season, but the difference truly showed up on the canopy closure (due to the increased leaf diameter). The 20” rows canopied 5 days sooner than the control. The plant color/health was slightly better in the acres with the full rate of AgPhRx. The soybeans yielded on average 9.74 bushel better than the soybeans in the control area.
Overall we would defiantly recommend and encourage the use of AgPhRx in any situation where ground or surface water is the carrier for corn and soybeans.
