Where to use

  • icon Long Description

    EnviroPlex is a unique, highly concentrated liquid organic soil conditioner produced from a proprietary humate extraction process. EnviroPlex contains 22% humic acids derived from leonardite ore. These humates have an extremely high cation exchange capacity (CEC) that is several times higher than soil organic matter. Humic acids have the proven ability to hold positively charged ions such as potassium, calcium, magnesium, iron, and manganese, as well as several other metal nutrients. This effect allows EnviroPlex to chelate metal nutrients and increase nutrient availability to the plant.

    In addition, the high concentration of carbon in EnviroPlex helps stimulate and enhance microbial activity. Stimulated microbes improve nutrient cycling, organic matter digestion, and other beneficial processes within the soil. This is particularly beneficial in sandy soils.

  • icon Problems Addressed

    Use of EnviroPlex may improve the following soil conditions:

    • Poor nutrient retention in sandy soils
    • Low levels of soil microbial activity
    • Anaerobic soil conditions
    • Soil compaction
    • Poor water infiltration

  • icon Application Instructions

    EnviroPlex can be applied through fertigation, conventional spray, or root injection. It may be applied alone or tank mixed with other products. Shake well before using.

    Apply 3 to 6 oz. diluted in 1 to 2 gallons of water per 1,000 sq. ft. (1 to 2 gallons diluted in 40 to 80 gallons of water per acre) per month.

    Dilution Rate: Mix 12 fl. oz. of EnviroPlex per 100-gallon tank. Apply up to 4 times per year or as needed.
    Operating pressure: 150 – 200 lbs PSI or ½ gal per 4 seconds

    Area Method:
    Trees: Apply 50 gallons of solution per 1,000 sq. ft. Inject 4-8 inches into the soil where the feeder roots typically occur. Begin injections 1-3 feet out from the trunk to avoid injury to large roots and work in a grid pattern away from the tree to within 2 feet of the drip line.
    Apply 1 pint (16 fl. oz.) of diluted solution per injection site at 18 inch spacing or ½ gallon (64 fl. oz.) of diluted solution per injection site at 3 foot spacing.
    Shrubs: Apply 50 gallons of solution per 1,000 sq. ft. Inject one pint (16 fl. oz.) of diluted solution per injection site. Inject 4-6 inches into the soil with 18 inch spacing between injections.

    DBH Method: Use the chart below to determine the volume of diluted solution to apply per inch of trunk diameter at breast height (DBH).

    Tree Size (DBH Inch) Diluted Solution / Inch DBH
    Very Small (1-4″) 0.5 gallon (64 fl. oz.)
    Sm (5-7″) 1 gallon
    Sm – Med (8-11″) 1.5 gallons
    Medium (12-15″) 2 gallons
    Med – Lrg (15-19″) 2.5 gallons
    Large (20+”) 3 gallons

    ✝ Compatibility: perform a standard jar test to check compatibility with other products before mixing.
