Fertilizer programs should begin with accurate soil testing. Growers who can self-sample reduce costs and better understand their soil situations. Review best practices so your samples lead to more reliable results and more educated management decisions.

Many farmers feel it is a greater agronomic benefit to apply nitrogen (N) in the spring rather than in the fall, because it coincides with the nitrogen needs of the corn crop. With this thought, a key question of many growers is, “Is a spring nitrogen stabilizer application still needed?”

Before planting, producers planning to use Mycogen^® brand BMR and TMF corn hybrids should carefully select which fields will be used for corn silage in order to maximize quality and yield.

The optimum time to select corn hybrids for the next season is often in the fall, shortly after harvest is complete and your observations from harvest are still fresh in your mind or can be reviewed in your records. Additionally, early ordering often can help ensure availability of hybrids and seed sizes that best fit your farming practices.

Harvesting corn for silage leaves little plant residue on the ground to help control water runoff and soil erosion. A cover crop either interseeded before or planted immediately after silage harvest will help protect the soil from wind and heavy rains. An established cover crop also helps improve soil structure and uptake of nutrients.

Since the adoption of corn hybrids with biotechnology traits, growers have continued to see more consistent 200-bushel-plus corn crops in past seasons. However, increased yields have created the challenge of dealing with increased levels of residue when planting next year’s crop.

Soil acidity is one of the primary fertility issues that can limit crop growth. High levels of acid can reduce nutrient availability, restrict root growth and increase the toxicity of some elements. Soil acidification occurs naturally as the result of rainfall, plant growth, breakdown of organic matter and the application of ammonia fertilizers. Applying lime reduces soil acidity and is a source of calcium (Ca) and magnesium (Mg).

Crop harvest removes valuable nutrients from the soil. Understanding the amount of nutrients removed is crucial to understanding how to fertilize for the highest yield potential next season. With high input costs, it can be tempting to skimp on nutrients to save cost. Over time, however, this approach can reduce yield potential and profitability.

Mastering foliar fertilizer application methods and timing help maximize your crop’s efficiency. Follow these guidelines for proper foliar fertilizer application.

Applying a portion of your crop’s nitrogen (N) requirement with irrigation water is a best management practice to reduce nitrate leaching in coarse soils. New irrigation technology systems have made the process of chemigating easier.
