Humus 400 is an exceptional and highly complex organic soil amendment derived from ancient geological carbon deposits – collectively referred to as Humates.
Humates contain active humic substances including humic acid and fulvic acid – both of which provide multiple benefits for soil health and plant nutrition.
Benefits include: high cation and anion exchange capacity, improving soil structure, buffering Sodium and Aluminium, stimulating beneficial microbes (eg. fungi), retaining soil moisture, and preventing nutrient leaching and/or lock-ups.
Humus 400 is an excellent amendment for most soil types – and is particularly beneficial in high Calcium (calcareous) soils and on sandy soils with low levels of organic matter.
