HyMax Phosphorus is a liquid biological additive formulated with beneficial microorganisms designed to assist with phosphorus availability in the plant root zone. Phosphorus is an essential element for plant development, playing a critical role in root establishment, energy transfer, and overall plant metabolism. In many growing environments, however, phosphorus can become bound within the media and unavailable for plant uptake.
HyMax Phosphorus contains naturally occurring phosphate-solubilising microorganisms that help convert unavailable phosphorus compounds into forms that plants can absorb. By supporting microbial activity in the rhizosphere, the product helps maintain a biologically active root environment where phosphorus can be more efficiently cycled and utilised.
The liquid formulation allows HyMax Phosphorus to be applied easily through reservoirs, irrigation systems, or direct root-zone drenches. It is suitable for use across hydroponic systems, coco substrates, and soil-based growing media, making it a versatile biological additive for a wide range of cultivation methods.
