1. Can Soil Information Better Inform Canopy Sensor Algorithms for Corn? Corn production is often limited by the loss of nitrogen (N) due to leaching, volatilization and denitrification. The use of canopy sensors for making in-season N fertilizer applications has been proven effective in matching plant N requirements with periods of rapid N uptake (V7-V11), reducing the amount of N lost to these processes. However, N recommendation algorithms used in conjunction with canopy sensor measurements have not proven accurate in many fields of the U.S. Cornbelt, resulting in... , N.R. Kitchen, J.

2. Changes in Soil Test Phosphorus as a Function of Inorganic and Organic Phosphorus in Animal Manure Understanding how and why soil test phosphorus (P) levels increase with manure and fertilizer application is important to assist in improvi ng any nutrient management plan. An incubation study investigated the change in soil test P (STP) after 42 different animal manures (dairy, beef, swine, chicken, turkey, goat, sheep, and horse) or fer tilizer were applied at a rate of 40 mg total P kg -1 to 25 different agriculturally important soils of Wisconsin. Both liquid and solid dairy and swine manure... Download paper
