Insect and weed problems can arise throughout the growing season. But what about mineral deficiencies? Today, we are going to discuss nitrogen and sulfur fertilization in soybeans! Does it improve yield? That is what this latest blog will look at!<\/p>\n\n\n\n

Nitrogen (N)<\/h2>\n\n\n\n

Even though soybeans capture N from the air, deficiencies<\/a> are common. Nitrogen requirements increase at stages R4 and R5, more especially when a soybean yield surpasses 70 bushels per acre. To produce such a high yield, a population needs 200 to 300 pounds of N per acre. <\/p>\n\n\n\n

Deficiencies most often arise when soil is too wet, poorly aerated or too dry. Nitrogen fixation becomes more difficult in these conditions. Leaves turn light green, and problems with nodulation or roots may be observed.<\/p>\n\n\n\n

Important<\/u><\/strong>: If nitrogen deficiencies are not corrected, they can cause leaves to turn brown and necrotic.<\/p>\n\n\n\n

Sulfur (S)<\/h2>\n\n\n\n

Sulfur aids in the formation of essential amino acids and nitrogen absorption. It allows the soybean to maintain optimum growth throughout the vegetative and reproductive stages. In other words, this nutrient plays an important role in seed development and the process of photosynthesis.<\/p>\n\n\n\n

Several factors contribute to sulfur deficiencies in soybeans:<\/p>\n\n\n\n
