    Key Features:

    All-Natural & Compost-Based: Derived from biologically stable compost, natural potash, and feathermeal, providing a balanced supply of slow-release nitrogen and essential nutrients.

    Builds Soil Health: Adds 50% organic matter by weight, increasing Cation Exchange Capacity (CEC) and improving soil's nutrient-holding capability over time.

    Enhances Plant Resilience: Improves tolerance to hot, dry conditions and supports healthy root development.

    Rich in Humic Acid: Contains approximately 5% humic acid to stimulate beneficial microbial activity and nutrient uptake.

    Safe & Clean: Pathogen-free and weed-seed-free with no wait times required between application and harvest for edible crops.

    Improves Soil Structure: Boosts soil aggregate stability, porosity, and water-holding capacity, creating an optimal environment for root growth.

    Enhances Soil Biology: Introduces beneficial post-based microorganisms to restore life in poor or degraded soils.

    Buffers Soil pH: Increases soil’s buffering capacity to maintain a stable pH environment and suppress plant pathogens naturally.
