Beware of potassium deficiency: A three-front assault to the profitability of crop production

Описание к видео Beware of potassium deficiency: A three-front assault to the profitability of crop production

Soil testing for potassium (K) is useful but is a less reliable diagnostic tool for phosphorus or lime requirements. The presentation will provide information to back Antonio's old saying "For K is better to err for higher tests and rates than to err for less than actually needed". A K deficiency can have more severe impacts on yield because it reduces the corn capacity to response to nitrogen and can increase the severity of various soybean
diseases and pests.
