The Importance of Early Season Phosphorus Nutrition
Phosphorus (P) fertilization is a major input in crop production on the Great Plains, as many soils lack sufficient P for effective crop production. To optimize crop nutrition, P must be available to the crop in adequate amounts early in the growing season. Phosphorus is needed from the earliest stages of crop growth, because it is important in nearly all energy-requiring processes in the plant...
متن کاملCorn yield response to polymer and non-coated urea placement and timings
Poorly drained claypan soils can increase the importance of tillage and N management for corn (Zea mays L.) production. Field research in 2008, 2009 and 2010 (high rainfall years) near Novelty, MO (40° 1' N, 92° 11' W) sought to determine the effect of polymer-coated urea (PCU) placement [strip-tillage (ST) deep banded and no-till (NT) broadcast] and application timing (fall, early preplant...
متن کاملCorn Response to within Row Plant Spacing
Key planting factors that influence corn stand establishment includes uniform depth and spacing of seed, correct seed population and optimizing the soil environment for rapid germination and uniform emergence. Other variables affecting stand establishment are seedbed quality (including soil moisture and temperature), seed quality and planter speed. Differences among fields for stand establishme...
متن کاملComparison of Exactrix and Conventional Fertilizer Application in Corn
Introduction The cost of nitrogen fertilizer increased dramatically in 2008 compared to previous years. As a result, producers began looking for ways to increase their nitrogen use efficiency. One product being promoted was an Exactrix system that injects anhydrous ammonia (NH3) as a liquid. The manufacturer of the Exactrix system claimed that nitrogen (N) rates could be reduced by as much as 3...
متن کاملCorn response to subsoiling and nematicide application.
A 2-year field study evaluated the influence of subsoiling and nematicide application, alone and in combination, on the growth and yield of field corn in a sandy soil in north-central Florida. The field had a 25-30-cm-deep tillage pan (plowpan) and was infested with Belonolaimus longicaudatus, Hoplolaimus galeatus, Trichodorus christei, and Pratylenchus spp. Subsoiling increased corn yield both...
