1. P and K Fertilizer on Bottomland SoilsP and K Fertility on Bottomland Soils 1 William 0. Thom 2 Most of the bottomland soils of western Kentucky are important areas for corn and soybean production. They consist of the Belknap, Karnak, Melvin, Sadler, Stendal and Waverly soil series that are somewhat poorl y to poorl y drained. A phosphorus and potassium study was initiated on the Belknap soil in Webster County. Soybeans and corn were alternated during the 4 year study. The P study consisted of 5 rates (0, 50, 100, 150 and 200 Ibs P 0... |
2. Trapping Function of Grassed FiltersThe potential to contaminate rivers, streams, and other natural water bodies with sediment, nutrients, pesticides and bacteria in runoff from agricultural land is a very important water quality issue. Conservation tillage has proven to be effective in decreasing soil exposure to rainfall, thus decreasing water runoff and erosion potential. Vegetative filters slow down runoff that allows sediment, nutrients, pesticides and bacteria to be deposited. Combining conservation tillage with vegetative filters... |
