“Key soil properties and their relationships with crop yields as affected by soil-landscape rehabilitation” with Dr. Sharon Schneider. Soil erosion is one of the major issues in agriculture that causes loss of the topsoil layer, reducing soil health and crop productivity. There are several ways to check soil erosion and its impacts on crop and soil health. One of the potential strategies to reduce the effect of past soil erosion is to reverse the soil erosion process by moving soil from where it was

“Recalibrating the Pennsylvania pre-sidedress soil nitrate test recommendations for modern corn production” with Charles White. Nitrogen management is one of the most important agronomic practices in modern crop production systems. The Pre-Sidedress Soil Nitrate Test, also known as the PSNT, gives farmers an estimation of plant available nitrogen in the soil, allowing them to calculate how much nitrogen the plants still need. The existing PSNT method was developed during the 1990’s. Now, farming
