BioAg Digest-it for Stubble has been formulated to rapidly digest and convert stubbles, crop residues, and other organic wastes (ideal as a compost starter) into humus and plant food, as well as increase soil microbial activity.

  • converts stubbles, residues, and other organic wastes into humus.
  • ideal for use as a compost starter.
  • eliminates need for stubble burning.
  • reduces carry-over of soil-borne pathogens.
  • reduces reliance on herbicides to control fallow weeds.
  • results in a loamy soil with improved workability and structurally able to support plant growth

As in the process of composting, microorganisms involved in the digestion of stubble require moisture to do their job.

As a general rule a 20 mm rainfall event provides enough moisture to warrant a stubble digestion program.

Average summer rainfall  in NSW and Victoria usually provides sufficient moisture for the digestion process to take place.

The key is timing applications with coming rains and gaining sufficient stubble contact with the soil.

Benefits of a well-managed and timely stubble digestion program 

During preparation and planting, there is better trash clearance and less “balling up”.

The stubble is more completely broken down, providing a source of nitrogen to better balance the carbon:nitrogen ratio.

This improves the breakdown process and reduces nitrogen immobilisation (draw down) during the critical early growth stage of the crop.

Sequestration of atmospheric nitrogen occurs during the decomposition process which means that there is less competition for nitrogen overall, resulting in less dependence on manufactured nitrogen fertilisers.

The improved biological activity has the ability to hold onto more nitrogen which is released in a more balanced manner during mineralisation and symbiotic plant biological processes.

Well-digested stubble decreases the hosts for fungal diseases and improves the soil biology habitat, offering better natural plant protection.
