Topdressing canola: How to maximize the benefits

To maximize the yield potential of winter canola, producers should topdress with nitrogen, sulfur, and possibly boron in the winter. Producers should make topdress applications with consideration for the environmental conditions, the nutrients needed, and the application method.

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.

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.

Is your plant nutrition program healthy?

One of the most important things you can do throughout the season to help increase yield potential is to ensure your crops have adequate nutrition. You can check nutrient levels by working with your agronomist to take multiple tissue samples throughout the season (often in concert with soil samples) to determine if critical nutrients are lacking.
