Black Ultra® is very different to any other humic, humate or fulvic substance material in the market. An advanced manufacturing process is used to fully react materials using a specific patent regulated by heat, pressure, time and pH in a highly controlled environment. This creates a very soluble, stable, free flowing and efficacious final material that can be used straight and/or in combination with other liquid N or N-P-K liquid fertilisers, resulting in better soil and plant health, increased yield potential and higher quality produce.
