1. Nutrient Efficiency Concepts for Phosphorus and Potassium Two measures of phosphorus (P) and potassium (K) efficiency that are of interest to producers are agronomic efficiency (AE) and partial nutrient balance (PNB). Agronomic efficiency considers crop response to a nutrient addition while PNBmeasures nutrient removal to nutrient use. Proper evaluation of AE requires long term monitoring. A single, large application of P or K can, over many years, result in an AE similar to smaller, annual applications. A larger initial dose will increase... T. Murrell Download paper
2. On-farm Trials and Statistics New technologies have made on-farm research easier to do. On-farm research networks exist in several states and are also being run by some national programs. These networks are becoming more common. University and/or government agency scientists and educators typically provide statistical expertise. Historical guidance for experimental design has focused on the randomized complete block design (RCBD). Statistical analyses that can be run easily are for an RCBD conducted in one site and one year.... T. Murrell Download paper
