Scouting and Treating for Sheath Blight in Rice As various fields pass midseason it’s time to scout closely for disease. Conditions seem to be nearly ideal for sheath blight development. […]
Changes were recently made to the University of Minnesota’s potassium (K) fertilizer guidelines for corn and soybean. These changes were made to reflect research evaluating critical soil test levels and […]
Decisions on optimal fertilizer management can be challenging in years with low commodity prices. Work is underway to overhaul the corn and soybean potassium (K) guidelines in Minnesota. When making […]
Every year, I see more potassium (K) deficiency in cotton. This isn’t surprising, since yields have increased with modern cultivars and yield expectations (Fig. 1). The bolls we’re asking plants […]
It has been said, “If it don’t rain, it don’t matter.” We are putting out landplaster in peanuts now to supplement calcium. If we don’t have enough calcium, we get “pops”. This […]
As crops are being harvested and grain is taken to the storage or elevator, it is time to recognize the amount of nutrients that are removed from your field by […]
If you have been applying potassium fertilizer at levels determined through routine soil sampling and are still observing potassium deficiency, there are 6 possible contributions to the problem.
Potassium is needed to regulate normal metabolic processes in the plant including photosynthesis and protein synthesis as well as maintaining plant osmotic pressure. Deficiencies of K in rice have been […]
