1. Soybean Response to Potassium Rates and PlacementSoils of northeast Missouri in heavy soybean producing counties have generally become depleted of available potassium. Reason for depletion can largely be pointed to soybean production and a general perception that soybeans do not respond to direct fertilizer application. With a significant portion of the soybean acres in east and northeast Missouri being tenant farmed, efficiency and utilization of direct fertilizer application by the current crop is even more important to the grower. Band application... |
2. On-Farm Nitrogen Fertilizer DemonstrationsThe Magdoff Pre-Sidedress Nitrate Test (PSNT) has been successful 1y used in the Northeast and humid parts of Midwest to improve N fertilizer recommendations. A modified version of the Magdoff PSNT was evaluated in 1989 and 1990 in Michigan. Fifty-three large scale on-farm corn N demonstrations were carried out. Two rates of N (a reduced rate and a high rate) were rep1 icated 3 to 6 times in each field. Forty-six sites showed no significant (p=.05) yield reduction due to the reduce N rate. Forty-nine... |
