1. Previous Management Impacts on Soil Phosphorus LevelsThe Homestead Acts of the early 19th century across many areas of the United States resulted in the formation of 65 ha (160 acre) farms. The areas where livestock were concentrated on these farms consisted of a small portion of the 65 ha. As farms have become larger, many of the original farm building sites have been abandoned. These abandoned farmsteads still affect management decisions today. The objectives of this study are to show the visual and statistical relationships between both existing... |
2. Delivering Continuing Education to Ag Professionals- The Crop Adviser InstituteContinuing education is essential for agricultural professionals, whether required by a certifjmg organization or completed voluntarily as a supplemental educational opportunity. Agricultural continuing education has traditionally been delivered on-site, but temporal, geographical, and other constraints often prevent individuals from attending these courses. The Crop Adviser Institute (CAI) has been established to provide an alternative method of delivering continuing education. Implementation of... |
3. Some Thoughts on Nutrient Mineralization and Cycling in No-Till SystemsHigh post-harvest residue accumulations (10+ tons/acre) often occur in crop sequences involving high yielding corn, spring wheat and soybean. Over the last decade, we have conducted several studies that show that N or P availability may be suppressed either through slow residue decomposition, slow mineralization or immobilization. Although several states provide fertilizer recommendation adjustments for no-till and for high residue accumulations, the recommendations are sometimes contradictory.... L. Cihacek, R. Alghamdi |
