The specialised line of Best Green Technologies is part of an innovative family of fertilizers, called “Humofolates”, whose production technology is internationally patented. The main feature of these high-tech formulated is the use of the purest raw materials during the production processes that guarantee excellent results in a very short time and in any pedoclimatic condition. Kalium maximum is an EC fertilizer with a high content of Potassium salts in suspension and Ureic Nitrogen. It is the result of extensive research and many scientific field trials conducted in different areas of the world, cultures and pedo-environmental conditions. It allows for the improvement of the efficiency of potassium fertilization through the quickly stimulation of the root system (which is a very important chemical element) with valuable results within a few days from the application. Kalium maximum can be applied on foliages and on root systems showing a rapid assimilation.
