1. Fertilizer and Manure Management Comparisons for Corn-Soybean Rotataions in MinnesotaA study was designed to evaluate the impact of P sources (fertilizer and manure), nutrient application methods (broadcast and subsurface bands), P rates (crop removal and twice crop removal), and tillage systems (no-till and conventional) on corn-soybean response. Results to date show higher yields using manure as compared to fertilizer as the P source. This could be attributed to a higher rate of P being applied using the manure. No-till systems measured greater yields in 1999 and 2000, primarily... |
2. Incorporating Cover Crops into No-till Production SystemsAlthough no-till soil management has many benef its, including protecting the soil from erosion, improving soil organic matter, and improving soil moisture storage, depending on environmental conditions there could be a number of potentia l problems. Implementation of no-till soil management in eastern South Da kota can lead to wet and cold soils at the time of planting. Cover crops have the potential to utilize exce ss soil moisture and improve soil conditions at planting. A field experiment was... |
3. Nutrient Deficiency Diagnostic Training with Field and Hydroponically Grown CropsThe Manitoba Crop Diagnostic School was initiated in 1995 and annually provides training for 350 - 400 field agronomists over a two week period in mid July. Symptons of nutrient deficiencies, other than Nitrogen (N), have proven difficult to demonstrate on the fertile high organic matter loam texturd soiles of the Carman Researh Station. The following techniques have been developed to demonstrate many of the macro and micronutient deficiencies which may occur in prairie crops.... |
