Hum-Amend MAX
Granular High-Carbon Stable Humus Soil CEC Amendment

Hum-Amend MAX is a powerful soil restoration amendment that provides high levels of organic carbon and stable humus to feed soil biology and increase soil cation exchange capacity (CEC). Hum-Amend MAX contains no animal manures; it is a homogenized blend of natural mined Leonardite and raw kelp meal combined with two of Nature’s most powerful substances, soluble humate (a biologically active source of humic and fulvic acids) and soluble seaweed extract (a biologically active source of trace elements and natural plant growth hormones). Hum-Amend MAX is safe for use on all types of plants at any time of year. Hum-Amend MAX can be used, along with Quantum Growth controlled soil inoculant, as part of a soil-building program to rejuvenate the soil structure quickly and naturally.

Hum-Amend MAX Benefits:

• Enhances soil organic matter naturally.
• Provides essential soil micronutrients.
• Feeds soil biology to provide a longer-lasting and quicker acting soil building program.
• Homogeneously blended prills (pellets)  for a convenient granular application.

Hum-Amend MAX is an easy and natural way to build soil structure, add organic matter and micronutrients and increase essential soil biology.
