Overview

About this product

TerraPlus K 6-3-18(+3) — organo-mineral fertilizer with a high potassium content (18% K2O) and 35% organic matter, supplemented with humic acids and alginates. Per the maker, humic acids improve the soil's ability to hold nutrients and water, and alginates promote the formation of stable clay-humus complexes; on humus-poor areas, applying organic matter increases biological activity.

Nitrogen is 6% in three forms, most of it organic (3.1%); it also contains 3% MgO, 7.5% sulfur and 0.5% iron. Recommended for areas with robotic mowers.

Granules 1–3 mm, 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.
