Corn planting is right upon us in many areas. Once the weather cooperates, it won’t be long before planters begin hitting the field. Make sure field conditions are acceptable before beginning planting. A general rule of thumb is that if soil makes a ribbon when pressed between the thumb and finger, it’s too wet and compaction could become an issue. Another critical piece to remember is planting depth. Most extension services recommend planting corn at a depth of 1.5-2 inches. My preference is a 2 inch minimum, as soil temperature swings are reduced at deeper depth, and this could be used as insulation against chilling injury in early planted corn.
Pioneer Premium Seed Treatment (PPST)
A new corn seed treatment offering from DuPont Pioneer, PPST 250 plus LumiviaTM, provides added protection to early corn growth by providing broad spectrum fungicides, as well as a new novel mode of action for added insect control. With an average yield advantage of 2.6 bu/A across all locations, this offering is exclusive to most new corn hybrid platforms offered in 2017.
Fertility Requirements for Corn and Soybeans
Determining yield goals can allow growers to better manage fertility needs on their farm for corn and soybeans. Proper nutrient availability is key to obtaining optimum yield potential for any crop. Nutrient uptake and removal rates vary among crops, as does the timing of uptake for individual nutrients. By analyzing soil tests, setting yield goals and understanding the nutrient removal amounts, growers can create a fertility plan to properly meet crop needs.
Nutrient uptake amounts should be the total of the amounts removed in the grain and the stover. Fertilizer amounts should be applied with respect to uptake periods of the specific crop. For example, nitrogen uptake in corn accelerates at approximately V6 growth stage, with 1/3 of total nitrogen taken up post-tassel. By applying the entire crop need at or soon after planting, potential for nutrient losses can occur, due to events such as heavy rains that may leach nutrients from the root zone. Split applications that provide nutrient needs closer to key uptake periods can improve nutrient efficiency and profitability.
