Lebosol-PK-Max — a liquid phosphorus-potassium fertilizer for foliar nutrition with 23.8% water-soluble P₂O₅ (385 g/l) and 27.4% K₂O (440 g/l), canister of 10 l.

Main advantages

  • P₂O₅ 385 g/l and K₂O 440 g/l — a concentrated PK solution
  • Potatoes 6–10 l/ha — for stolon thickening
  • Pome fruit at 4 and 2 weeks — storability and transport
  • Phosphorus and potassium — more efficient nitrogen uptake

Overview

About this product

Lebosol-PK-Max — a colourless solution for foliar nutrition with 23.8% water-soluble P₂O₅ (385 g/l) and 27.4% water-soluble K₂O (440 g/l); density 1.61 kg/l, pH 8.0. Per the maker, phosphorus supports the development of the root system, flowers and fruit, potassium regulates water balance, and a plant well supplied with them takes up nitrogen more efficiently and keeps the harvested produce longer.

Rates from 6 l/ha on sunflower and legumes to 6–10 l/ha on potatoes during stolon thickening; on pome fruit and table grapes 6–8 l/ha. Canister of 10 l.
