Scientists meet to chart future course for improving P nutrition

A small group of internationally recognized scientists met recently in Kona Beach, Hawaii to brainstorm the future of potassium (K) nutrition of crops. The Frontiers in Potassium Science Workshop focused on creating a list of strategies for explaining and managing significant spatial and temporal variability in the contributions of fertilizer K and soil K to plant nutrition.

Micronutrients

Understanding and applying chelated fertilizer based on soil pH

Plant nutrients are one of the environmental factors essential for crop growth and development. Nutrient management is crucial for optimal productivity in commercial crop production. Those nutrients in concentrations of ≤ 100 parts per million (ppm) in plant tissues are described as micronutrients and include iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), boron (B), chlorine (Cl), molybdenum (Mo), and nickel (Ni). Micronutrients such as Fe, Mn, Zn, and Cu are easily oxidized or precipitated in soil, and their utilization is, therefore, not very efficient. Chelated fertilizers have been developed to increase micronutrient utilization efficiency.

Should you consider in-furrow starter in corn?

The use of starter fertilizer placement on the seed (known as in-furrow placement) is commonplace in many areas of Minnesota. Daniel Kaiser, Extension nutrient management specialist, University of Minnesota, says he commonly receives questions on the value of in-furrow starter fertilizer when corn prices are low. The application of liquid fertilizer with the planter presents additional costs, which may or may not be warranted depending on the year and where a field is located within Minnesota. There are a few things to consider the when and what when utilizing starter fertilizer banded on the corn seed.

Micronutrient management in Nebraska

Of the 16 elements known to be essential for plant growth, seven are used in very small amounts and, with the exception of iron, have an uptake of less than 1 pound per acre per year. These are classified as micronutrients and include zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), boron (B), molybdenum (Mo), and chlorine (Cl). Interest in micronutrients has increased with increasing yield levels, increasing rates of nutrient removal in harvests, and availability of alternative micronutrient products.
