For general use, the dilution recommendation is 1 part Terreplenish® to 25 parts water. Terreplenish® can be applied 1:10 only in-furrow, pre-plant or post harvest. The following are recommended diluation rates for specific applications: For a quart use: 1.25 oz/ 37 ml For a gallon use: 5 oz/ 148 ml For a 2-gallon use: 12.5 oz/ 370 ml.


For Pre-Plant Application: Apply 7-10 days ahead of seeding For Post-Plant Application: Apply directly after plant emergence For Greenhouse Agriculture: Apply foliar bi-weekly Application may be repeated every 7 days or less based on preference. Apply in low sun. Soil applied Terreplenish® is optimal in fall and will accelerate breakdown of crop residue. Note: Once Terreplenish® is mixed with water, it should be applied within 6 hours and used completely.


Stored Terreplenish® is useful for up to 24 months in normal conditions. Optimal storage conditions are out of direct sunlight and within a temperature range of 39° to 110° Fahrenheit. Avoid prolonged exposure to oxygen by closing container cap after each use. Do not reuse unused product that has been mixed and held in one location for more than 4 hours. PH of product is 3.4-4.2. This range is a good indicator of viability with no requirement for pH balance.


Our range of 1-5 gallons per acre is seemingly wide except when you consider how many guests are coming to dinner. 1,000 apple trees per acre have root structures underground that are 20 times as great as a typical corn field. Thinking of our production acre on a three-dimensional basis, the density, age and complexity of the part of the plant that lives in the rhizosphere has vast variability that can only be imagined as it cannot be seen. Using apple trees compared to corn as an example, 1 gallon per acre of TP in corn is a much higher rate than 5 gallons per acre in apple trees. Compounding the rate per acre decision is the environment where we a placing these living communities of microbes that we call Terreplenish. Is it hostile or friendly? Is it dry or water logged? Generally, the more friendly the soil environment, the more likely that a lower rate will be sufficient. In the most hostile soil environment, the highest recommended rate may not be sufficient. When considering foliar application, the same considerations should be used. The above ground plant structure has a living biome when plants are healthy. This is known as the phyllosphere.

The phyllosphere is a term used in microbiology to refer to the total above-ground portions of plants as habitat for microorganisms. When determining application rate, the questions need to be answered about the volume and condition of the phyllosphere. The more friendly, the more forgiving and the lower rates will provide excellent performance. If the condition is more hostile, the higher rates may prove to be less effective than desired.

Once a proper rate application is established, Terreplenish® has a regnerative effect in replenishing soil multiple years following initial application.


Terreplenish is compatible with most herbicides, minor nutritional formulations and other low rate fertilizers. There are two issues to consider when tank mixing Terreplenish. A common jar test will indicate if the physical properties of the substances being combined have any caking, separating or any other adverse reaction. When tank mixing Terreplensih, the other consideration is detriment effects on the living microbes. Generally, avoid salts, soaps and oils in addition to all insecticides, fungicides and nematicides.


Terreplenish® is a free living bacteria suspended in our proprietary liquid media concentrate and contains: Azotobacter, Lactobacillus, and Organic Acids.


Our label states to dilute Terreplenish with water 1-25 or 1-50. Why? What does this mean?

Terreplenish is not a fertilizer, however, the acid formed by the many microbes is a pH of 3.2-3.8. This is a moderate strength acid. It will irritate skin, not from toxicity, but from acidity which is slightly more acidic than vinegar. Some organic growers use vinegar diluted with water to kill weeds. We do not want any grower to harm actively growing plants with Terreplenish. 1-25 dilution of Terreplenish to water will not harm actively growing plants. Dilution recommendations are only a guideline to prevent plant injury and does not typically correlate with the recommended effective rate of Terreplenish per acre. When living plants are not present, dilution recommendations are not relevant and most commonly refer to foliar applications only. However, for liability requirements of the label, we have to state a minimum of 1-25 dilution with clean water. When no plants are present, mix only to get good physical distribution with the equipment being used. For most crops, we strive to effectively apply 1-5 gallons of Terreplenish per acre per application, regardless of how much water we mix.
