ADOB® NPK Foliar 4-12-38 + micro

Characteristics

ADOB® NPK Foliar 4-12-38 + micro is a multinutrient, multifunctional crystalline fertiliser. This fully water-soluble product is designed for foliar, fertigation and soilless applications to arable, vegetable, floriculture and orchard crops. It supplies plants with the essential nutrients nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and sulphur (S), ensuring the optimal development of their roots and aboveground parts. Thanks to its very high content of potassium (the quality nutrient), it stimulates the bulking up of fruits and tubers by boosting accumulation of carbohydrates and oils. It also contains all six micronutrients: boron (B), copper (Cu), iron (Fe), molybdenum (Mo), manganese (Mn) and zinc (Zn).

All micronutrients (except boron and molybdenum) are chelated by the modern, biodegradable IDHA agent, while boron and molybdenum (which cannot be chelated) are present as water-soluble, inorganic components. As a result, all nutrients are readily and quickly available to all crop plants. This unique combination of essential nutrients ensures the optimal development of plant roots, flowers and fruits.

ADOB® NPK Foliar 4-12-38 + micro also improves both the health and quality of plants during their preharvest and postharvest life. It reduces lodging, effectively prevents nutrient deficiencies and enhances plant resistance to salinity and occasional water-stress conditions.
