Balance Nutrients to Optimise Humus
by Dr Ash Martin PhD BSc(For)Hons
Storing carbon in resistant soil organic matter has multiple benefits to soil health and productivity, but retaining crop residues is not enough to make this happen. Australian research has shown that matching soil nutrient ratios close to those of humus is essential to build resistant carbon stocks in the soil.
For an in-depth view of how balancing soil nutrients can help to build soil humus have a look at this research:
