FAQ
Why a maize-specific fertilizer?
The organic matter, humic acid and nutrient balance and the application timing are set for maize (corn), so the product fits the crop programme without extra blending.
Does it replace NPK fertilizer?
No. It provides organic carbon and a modest nutrient base. Keep your mineral programme and adjust it to soil tests.
