Phosphorus (P) fertilizer is often added to cropping systems to increase yield, but growers should not overlook the importance of micronutrients like Zinc (Zn). Understanding some of the nutrient interactions that affect nutrient availability can help with management decisions like fertilizer source.
Over the last several decades there have been substantial yield improvements in soybean.
Although boron (B) is considered the most deficient micronutrient in the world after zinc, dynamics of B use in plants and soils have continued to perplex farmers, agronomists and researchers for decades.
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).
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 objective of a recently published study conducted by University of Illinois plant physiologist Dr. Fred Below and recent doctoral graduates Dr. Ross Bender and Dr. Jason Haegele was to identify which secondary macronutrients and micronutrients demand attention in a new era of soybean production.
The growing season of 2014 has the potential to yield a record harvest in many areas of the country. With good weather conditions, high soil fertility and a combination of high-yielding varieties, crops look strong and healthy. But there’s more being removed from the fields than just a crop harvest — record yields mean record nutrient removal from the soil.
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.

Record yields equal record removal of nutrients and should indicate a need for record soil nutrient replenishment.
Hybrids designed to resist corn rootworm require an extra boost of one of the most important nutrients, potassium (K).
Corn yields today are skyrocketing. Continued advancements in corn genetics and the next generation of insect-control traits have played a large role in improving yield potential. However, new research shows more than just yield potential of corn is changing.
