1. New Techniques and Methods of Disseminating Information in View of Budgetary Constraints by the University of Illinois The Cooperative Extension Service a t the University faces increased demands for educational services. This increaase is in an environment marked by increasing costs, and stable to decreased financial support--especially from the Federal partner. The situation we face in Illinois is similar to that faced by many other State Cooperative Extension Services. We are better o f f than some states--worse o f f than others. What of the future? Will we be able to deliver viable programs to farmers and agri-business... Download paper
2. Phosphorus Runoff From Incorporated and Surface-Applied Fertilizer and Manure Continued inputs of fertiher and manure in excess of crop requirements have led to a build-up of soil phosphorus (I?) levels, creating an environmental rather than agronomic concern (Sharpley et al., 1994). The objective of this study was to evaluate the effects of soil test P level, source of P amendments, tillage, and manure application method on P runoff from agricultural soils. The treatments consisted of swine manure surface applied and injected at rates of 29 and 59 Ib acre-' of P, and triple... Download paper
3. What Do You Do When Your N-Rich Reference Fails? In recent years, canopy reflectance sensing has b een investigated for in-season assessment of crop N health and fertilization. Typically, the procedure followed co mpares the crop in an area known to be non-limiting in N (the N-rich area) to the crop in a target area, which may be inadequately fertilized. Measurements from the two areas are used to calculate a relative reflectance to represent the potential need for add itional N fertilizer. Establishing N rich areas or strips is often inconvenient...
