Start Right With Starter Fertilizer:Farm Journal Test Plots show strong yield responses to placement, product combinations

摘要

Every year, we learn valuable lessons from the Farm Journal Test Plots due to ever-changing field environments and weather conditions. Regardless of the variations, Farm Journal Field Agronomist Ken Ferrie can pinpoint yield gain and loss thanks to established and consistent protocols. Those procedures were especially beneficial in 2015 when documenting aggressive and consistent yield responses in a starter test plot in Illinois.Based on past data, we've found dual starter placement yields more than just in-furrow or just 2x2 applications. On average, there's a 7 bu. to 10 bu. response to starter placed 2x2 and a 3 bu. to 5 bu. response to in-furrow application. With dual placement, the plots have shown a 15 bu. to 20 bu. yield increase.
