From natural plant nutrition and trace-element correction to complete NPK programmes — a full nutrition palette from Bio Plant Solutions BCT biological fertilizers, 100% vegan.
Liquid natural chelated trace elements, proven stable and effective up to pH 7–7.5. Each one corrects a specific deficiency without disturbing the rest of the nutrient balance.
100% water-soluble NPK for drip and foliar feeding, in three balanced varieties that carry the crop from vegetative into generative growth.
Fast-acting granular NPK 11–0–5 with directly available nitrogen, then a slow release that feeds the crop for weeks. Spread with standard equipment.
Clean inputs, fast availability, and no compromise on compatibility with the programme you already run.
