The Humuson range

Crop nutrition and biological solutions, from soil to leaf.

Microbiological fertilisers, biostimulants and crop nutrition — foliar and irrigation feeds, trace elements, and basal and top dressings. Each carries its own published composition, rates and crop suitability — nothing is listed for a job its documentation does not claim.
