Water-soluble complex NPK fertilizer 18-18-18 with micronutrients, of which Cu, Fe, Mn and Zn are chelated with EDTA, and an acidic solution reaction (pH 4–5) for fertigation.

Main advantages

  • Solution pH 4–5 — less dripper clogging
  • NPK 18-18-18 — balanced nutrition
  • Cu, Fe, Mn, Zn chelated with EDTA — per the maker
  • Granulometry — less dust and caking

Overview

About this product

Basaplant Black — water-soluble NPK fertilizer 18-18-18 with a balanced formula, which the maker recommends for better flowering and balanced plant growth. The 18% nitrogen consists of 9.9% nitrate and 8.1% ammonium, the phosphorus is fully water-soluble, and copper, iron, manganese and zinc are chelated with EDTA.

A 1:10 solution in neutral water has pH 4–5: the acidic reaction acidifies the irrigation water and reduces dripper clogging. The granulometry reduces dusting and caking.

It is used for fertigation, with the concentration chosen by crop and water salinity; it is not mixed with calcium salts. 25 kg bag.

Questions & answers

What farmers ask most

  • Rates depend on crop, prior history, soil-analysis results, and current soil nutrient status. A typical NPK complex on cereals is 150–300 kg/ha. Use the NPK calculator on adam.ua or consult an agronomist for an exact dose.
