Soybeans
Soybeans require comprehensive fertility programs if they are to realize optimal plant health and maximize crop success. Soybeans frequently experience potassium deficiency which can be spotted as chlorosis at leaf margins and between veins. This is initially visible on older leaves. However, in severe cases, all but the youngest leaves might display these symptoms.
Stunted plants have a pale green color, which is similar in appearance to plants with a nitrogen deficiency. However, when the plant is experiencing a sulfur deficiency, chlorosis may be more apparent on the upper leaves. The deficiency is most likely to present during cool, wet conditions or in sandy soils with a low organic matter content.
Our Crop Vitality product portfolio will successfully address your crop nutrition needs and correct any nutrient deficiencies.

Potassium
Meeting the high potassium demand of soybeans in-season can be problematic depending on climate conditions. In drought conditions, root growth is reduced, leading to less “scavenging” for potassium in the soil profile. Less water means less diffusion and movement of potassium to the root system for uptake, which reduces plant availability. When moisture is in great supply, potassium could be lost from coarse textured soils, a concern when potassium chloride has been applied and larger rainfall events occur.
K-Row 23® and KTS® are both excellent sources of potassium and sulfur. K-Row 23 can be applied safely in-furrow and out of furrow, in many starter fertilizer blends. KTS provides sulfur (S) in the thiosulfate form. Thiosulfate has been shown to help improve availability of nutrients like phosphorous and micronutrients like manganese, zinc, and iron.

Sulfur
Sulfur is essential for nitrogen fixation and utilization within soybeans. Early-season sulfur applications are critical to early planted soybeans, as sulfur is less available in soil during cooler temperatures. Peak sulfur uptake occurs during the reproductive growth stages. This illustrates the importance of having sulfur available throughout the season. Crop Vitality fertilizers pair sulfur with essential nutrients, delivering multiple benefits to the crop in one product.
Consult with your local agronomist or Crop Vitality Specialist to determine appropriate in-season crop nutrient plans.
