Concentrated liquid fertilizer for foliar application that provides the plants with nutrients in such a proportion as to meet the special nutritional needs of rapeseed and other oilseeds. It has particularly high concentrations of sulfur, magnesium and of course nitrogen from the trace elements boron, manganese, iron and zinc while it also contains molybdenum, copper and titanium which are all important trace elements. It is noted that oilseed crops have increased sulfur requirements and are sensitive to boron, manganese and molybdenum deficiencies. Thanks to the complete chelation of trace elements, the nitrogen and magnesium content but also the revolutionary INT technology (Innovative Nutrient Transfer Technology), they have good and fast absorption of nutrients from plants and their utilization resulting in improved photosynthesis, growth and production. .
