Description / L-CBF BOOST™ 220L Barrel

L-CBF BOOST™ is a Liquid-Carbon Based Fertiliser that is suitable for use across agriculture. It combines readily available carbon (as sucrose) with a balanced nutritional package and is designed to feed the soil biology and enhance plant nutrient availability.

L-CBF BOOST™ brings readily available carbon and other growth factors to the soil biology. It works by feeding the microbes in the soil, hence promoting the health of the soil leading to improved nutrient availability for the growing plant. Extensive use on farm and commercial enterprises over the last 7 years, along with independent and university trial work has demonstrated significant yield responses across a wide variety of crops.

L-CBF BOOST™  is a safe, simple and cost effective way of providing readily available carbon to complement an existing fertiliser plan. For more information on L-CBF BOOST™ please click here.
