Boron – A Critical Nutrient Required for Root Growth and Potassium Uptake

A balanced supply of essential macro- and micronutrients is one of the most important factors to achieve higher crop yields. Boron (B) is one of eight micronutrients needed for proper plant growth. Lack of B in plant tissue can reduce cell wall function and stability, cell elongation, root growth, nutrient uptake and crop yields. This article describes the role of B in root growth and nutrient uptake, with a special emphasis on potassium (K).

Macronutrients for 'Macro' Soybean Yields

While soybeans were introduced to the United States in the late 1800s as a forage source for cattle, it wasn't until 1935 that the number of acres for soybean grain exceeded forage-based acres. This milestone marked the beginning of a new era in soybean production, which has influenced the fertility needs of soybeans.

The Gap Between Macros and Micros Is Smaller than You Think

Even with the increased focus on micronutrients and their importance to crop health and yields, basing a solid nutrient management plan on macronutrients is still critical. While macronutrients and micronutrients certainly work best together to create a balanced approach to crop nutrition, the key difference between them is the amount needed for proper plant growth.

Phosphorus Fertility – Do We Need to Look Deeper?

When measuring phosphorus (P) availability in the soil profile, agronomists tend to focus on the first few inches of topsoil. After all, P fertilizer is applied to the upper soil layer, reduced tillage limits soil mixing, most roots are present at upper depths and P is relatively immobile in the soil. So, the top layer should be where plants take most P from, right? Not entirely.

Availability of Phosphorus Fertilizer

A recent study of phosphorus (P) reaction to dry and wet soils offers insight about the fate and availability of phosphorus fertilizer when applied to dry soils.
