Efficiency Of Nitrogen Use With Corn On A Tiled And Untiled Soil, Lloyd W. Murdock, John Kavanaugh, Harold F. Miller, Grant Thomas, Monroe Rasnake

Agronomy Notes

Excessive water is one of the largest contributors to the inefficient use of nitrogen in Kentucky. Because of this, nitrogen is often lost by both leaching and,denitrification. The amount, of these losses can be great depending on soil type and weather. Well-drained soils in Kentucky have been shown to lose less nitrogen than poorly drained soils. The nitrogen lost from well drained soils is usually due, to leaching. The nitrogen in the soil, even soon after applying non-nitrate forms of fertilizer N, is mostly in the water soluble nitrate form. When more water falls onto a well-drained soil than the …
