1. Nitrogen Management for no-till Grain SorghumField experiments evaluating the effects of nitrogen management for no-till dryland grain sorghum were coacted in 1985 and 1986. Nitrogen rates (0, 50, 100 lbs N/A and placement methods for urea ammonium nitrate solution (UAN) have been evaluated in eastern Kansas. Placement methods have included surface broadcast, surface banded, pressure injected, and knifed. Results to date shm that nitrogen consistently increases yields and tissue and grain N contents, and that method of UAN placement produces... |
2. Effects of Chloride Rates and Sources on Winter Wheat in KansasOn wheat, and some other cereal grains, chloride has been reported to have an effect on plant diseases, either suppressing the disease organism or causing the plant to be able to withstand infection. It is hypothesized that yield increases are due to these effects. Researchers from several states have been able to show yield increases from chloride containing fertilizers. The most common source is potassium chloride, KC1. In many cases, soil test potassium levels are high, and most soil test recommendations... |
3. Hypoxia in the Northern Gulf of Mexico- a 2006 UpdateBased on several science reports and opinions, hypoxia (dissolved oxygen of -Mexico was previously thought to be caused by excessive loads or discharge of nitrogen (N) - primarily as nitrate plus nitrite-N (hereafter referred to as nitrate-N), and exacerbated by fertilizer N inputs (CENR, 2000). These science reports estimated lhat about 90% of the nitrate load to the Gulf was from nonpoint sources in the Mississippi and Atchafalaya River Basin (MARB). They also estimated about 56% of the nitrate-N... |
