Overview

About this product

NPK 15:15:15+10S (nitroammophoska) — a complex nitrogen-phosphorus-potassium fertilizer with 15% nitrogen, 15% phosphates, 15% potassium and 10% sulphur. The seller advises it for basal, pre-sowing and at-sowing application and for root and foliar feeding of growing plants of various crops on almost any soil, including legumes, cereals and garden crops.

Granules under 1 mm make up not more than 2%, 2–4 mm not less than 80%, and there are none larger than 6 mm. Per the seller, the substances dissolve easily and are taken up well, and sulphur promotes the uptake of nitrogen and phosphorus.

Questions & answers

What farmers ask most

  • Rates depend on crop, prior history and soil analysis. Urea and other straight nitrogen grades are not an NPK complex: a cereal ballpark is often 100–250 kg/ha of product, but the exact dose is an agronomist's call.
