Soil Carbon

Microsoil's range of liquid biological fertilisers has a proven efficacy in improving soil health and building soil carbon levels. This provides significant benefits to the environment via the sequestration of CO2 from the atmosphere as well as quantifiable improvements to agriculture. An increased level of soil carbon has a direct influence on enhanced soil biology and greater Water Use Efficiency.

Microsoil is ideally positioned to play a positive role in any future 'carbon based' economy. Of more importance to the Australian farmer though is the dramatic effect that increased soil carbon levels can have on the soil’s ability to retain moisture for longer periods.

The below trials monitored a transition to significantly reduced synthetic fertiliser input whilst applying Microsoil’s biological mineral fertilisers that fostered microbial development of carbon in the soil.

Widespread soil samples tested by Charles Sturt University have highlighted significant improvements in many aspects of soil health. As an indicator of Water Use Efficiency the trials tracked improvements in Total Carbon levels.  

 
Soil Carbon increased 1.3pp or 180%

Carbon trading aside, there are substantial benefits to be gained by farmers who increase their soil carbon level. Importantly an increase in soil carbon allows the soil to retain more moisture and this can be vital in the latter stages of crop development and ongoing pasture improvement. The soil's ability to retain extra water as carbon levels increase is highlighted in the table below.
