Soybean Fertilizer Recommendations – How to Increase Soybean Yields

Soybean fertilizer recommendations will vary depending on the type of soil, but there are some general guidelines that can help you get started. So whether you’re a seasoned pro or just starting out with soybean production, be sure to read on for the latest information on soybean fertilizer!

How to Choose the Best Soybean Fertilizer? N, P and K Nutrients

Soil type is one of the most important factors to consider when determining the best soybean fertilizer for your needs. For example, sandy and loamy soils usually require more nitrogen (N) than clay or silty soils since they tend to drain faster and are less likely to hold onto nutrients. In addition, if you have a soil test, this will help you determine the exact nutrient levels in your soil and how much of each nutrient to add to get the most of your soybean plants.

When Is N Fertilizer a Good Choice?

Nitrogen is the most commonly used nutrient for soybeans, and it’s generally applied as a side-dressing in mid-season or after full bloom. However, you may need to apply a starter fertilizer containing additional N when planting your soybean seeds.

Other important nutrients include phosphorus (P) and potassium (K), which are often referred to as “macronutrients” because they’re needed in relatively large amounts. Application rates will vary depending on your soil test results and other factors, such as crop rotation, previous crop residue levels, and rainfall amounts.

Fertilizer Application

In addition to the type of fertilizer you use, the application method is another important factor for the nutrient uptake. In general, there are three main types of application methods: broadcast, banding, and fertigation.

Broadcast applications are made by spreading the soybean fertilizer evenly over the entire field using a granular applicator or spreader. With banding, a narrow band of fertilizer is applied directly below the crop rows. This method is often used when it’s necessary to apply large amounts of N and/or P, since these nutrients can easily be washed away if not properly incorporated into the soil.

Fertigation involves injecting liquid fertilizer through drip irrigation systems or sprinkler systems. This method offers several advantages, including improved fertilizer utilization efficiency and more uniform distribution of nutrients.

Fertilization: How Much Fertilizer to Use Per Acre?

The exact amount of soybean fertilizer to apply per acre will depend on your soil type, soybean yield potential and goals, previous soybean crops, and other factors. In general, the recommended rates for N are between 50 and 150 pounds per acre (depending on the method of application), while P rates are typically 15-30 pounds per acre and K rates range from 75-150 pounds per acre. However, it’s important to consult a trusted source (such as a local extension agent or agricultural consultant) for more specific recommendations based on your individual soil and crop needs.

Soybean Production: How to Increase Soybean Crops?

Soybean growers who want to grow more bushels per acre should focus not only on choosing the right soybean fertilizer, but also on the following things:

  • nutrient management – this involves using the right amount and type of fertilizer;
  • yield response – this refers to the relationship between soil nutrient levels and soybean yield;
  • soil test levels – soil tests can help determine the nutrient levels in your soil, which will in turn help you identify any deficiencies;
  • soybean variety – different varieties of soybeans have different nutrient demands.
