1. Effect of Residual Profile Nitrate on Corn Response to N Fertilization in WisconsinResearch in several Great Plains and Western states has shown that crop yield response to fertilizer N is closely related to the amounts of residual nitrate in soil profiles. Based on this work, nitrogen fertilizer recommendations in these low-rainfall areas are adjusted to reflect the contribution of residual nitrate to the total crop nitrogen requirement. Use of residual profile nitrate data in development of N fertilizer recommendations has received much less research attention in the higher rainfall... |
2. Interrelationship of the Nitrogen Cycle and Carbon Sequestration- Greenhouse Gas Mitigation in Row CropsAgiculture's contribution to global warming is principally through its historical release of carbon in soil and vegetation to the atmosphere and through its contemporary release of nitrous oxide and methane. The sequestration of soil carbon in soils now depleted in soil organic matter is a well-known strategy for mitigating the buildup of COz in the atmosphere. Less well- recognized are other mitigation potentials such as better management of nitrogen fertility. A full-cost accounting of the effects... |
3. Overview of Biostimulant Classification and Industry PerspectiveThere are many but what is the definition of biostimulant? How are these products categorized? We will start off with definitions of commonly used terms around biostimulant products used in agriculture. The current categories in which biostimulant products fit, or do not fit into, are continually evolving as industry and regulatory work towards fine-toning definitions. As more products become commercially available, producers need to be aware of their advantages, as well as challenges, to maximize... C. Preston |
