Overview

About this product

NPK 5-18-18 (chlorine-free) — a mineral complex fertilizer without chlorine, intended for crops that tolerate chlorine poorly: potato, tomatoes, cucumbers, pepper, strawberry, raspberry, currant, beans, pea, other vegetable and fruit crops. Its nutrients are fast-dissolving and fully available.

The maker stresses the high water-soluble phosphorus content for a strong root system at the early stages and kieserite (MgSO4·H2O) as the basis of effectiveness. Rate: garden crops 100–300 kg/ha at a time, vegetable crops 100–300 kg/ha under irrigation and 300–800 kg/ha without irrigation, lawn grasses 2–4 kg per 100 m².
