PLONVIT^® KALPRIM used prophylactically is an effective source of potassium during periods of increased plant demand for potassium. The fertilizer is recommended when there are soil and cultivation conditions that limit the availability of this nutrient to plants (low pH, low soil moisture, high calcium and/or magnesium content, medium and heavy soils, high light intensity).
PLONVIT^® KALPRIM applied at the times and doses recommended in the fertilization programs of individual species, effectively supplements and/or corrects soil fertilization and provides potassium easily assimilated by plants at the stages when they show the greatest need for this element.

Intervention feeding is indicated when there are visual symptoms of potassium deficiency on plants or when the results of analysis of plant material indicate too low potassium content (latent deficiency).
