Product Application Rates



Product General Mixing Ratios

Agrostim™, Agroprime™, SuperGrow™Citrastim™ and Agrogen 7-7-7™.

All products are manufactured for foliar application but can also be applied through drip, irrigation or fertigation systems. All products are dry shipped. They can be applied as foliar applications at a general application rate or ratio of 50 to 1 (i.e. 50 gallons water to 1 lb. of product applied on a per acre basis.)

Products can be applied every 3 weeks to promote crop health, fruit quality and yield. For crops that are in need of accelerated recovery due to frost damage, stress, poor soil conditions, plant nematodes, fungal diseases, etc., then a more concentrated solution can be utilized. For example, 1.5 – 2.0 lbs. per acre per application.

Given the organic composition of the products, they can be mixed with most anything else you’re applying (i.e. fungicides) without any negative impact on the mixed product’s performance, our product’s performance or the plant itself. Products are compatible with low volumes sprayers at 20 gallons up to higher volumes at 100 gallons per acre.

Products can be used in commercial sprayers or applied via irrigation and drip systems. All products are water soluble and shouldn’t clog emitters or sprayers if they are first mixed into a 5 gallon bucket to dissolve the product thoroughly prior to placing into the sprayer holding tank or fertigation feeder system.

Agrogen™ 7-7-7 was developed for soil application to provide ongoing nutrition (i.e. application every 2-3 weeks) throughout the season to the vines via the drip system. It’s extremely soluble (98.5% solubility) so it won’t clog emitters. Application rate is one half (1/2) lb. of product every 2-3 weeks via the drip or irrigation system. It can also be applied as foliar using the standard rate of 1 lb. of product to 50 gallons of water per acre.

Agrostim™, Agroprime™, Citrastim™, SuperGrow™ and Agrogen™ have a minimum shelf life of 3 years if stored in a dry, cool location.

Microstim™ (Micronutrients)

Use 1/2 to 1 lb. of Microstim per acre for vegetables, trees, and row crops as a foliar application depending on the level of deficiency.

Apply Microstim at no more than 2 lbs. per acre as a foliar in post harvest sprays for trees, vines, nuts and citrus. Use sufficient water for good coverage. Follow all other directions and safety precautions currently on the label.


Fulvistim™ is compatible with most organic and non-organic fertilizers, nutrients, soil amendments foliars and may be added to most tank mixes. When used as a stand alone foliar spray, it may promote bloom and fruit set and stimulate root growth along with many other functions.

Typical foliar rates are 1 to 2 quarts per acre.

Consult ANDAMAN AG representative for crop specific mixing and application rates. We recommend always conducting a jar test prior to application if there are any concerns. 


Humistim is compatible with most organic and non-organic fertilizers, nutrients, pesticides, and fungicides. Humistim may be used on all crops, trees, vines, grasses, ornamental, and vegetable gardens.

Caution: If blended with acids or acid based fertilizers with a pH of 4 or less product must be continuously agitated during application to avoid settling out. 

Row Plants and Field Crops: Side dress 2 to 4 gallons per acre or water run 3 to 5 gallons per acre from 1 to 3 times per growing season. Consult ANDAMAN representative for crop specific application rates.

Citrus and Nut Groves: Side dress or water run at the rate of 2 to 4 gallons per acre combined with fertilizer or water run alone at the above rate. Product may also be spoon fed through drip or sprinkler irrigation.

Trees and Shrubs: Apply at the rate of 6 oz. per one gallon of container size after diluting with water at a rate of 4 to 1, then blend into bottom and sides of transplant plant cavity.

Lawn and Garden: Apply during over seeding, transition or to established turf at the rate of 1 gallon per 10,000 sq. ft.   Dilute at a minimum of 10 to 1 with water or other liquid fertilizers. May also be spoon fed through drip or sprinkler irrigation.



Suggested Applications and Rates:

General information: When in solution, use a recirculation pump to provide mild agitation to prevent settling. If excessive foaming occurs, add 4 to 8 fluid ounces of corn oil to the tank. Do not use commercial anti-foaming agents. For maximum benefits, use lower analysis fertilizers. Avoid the use of semi drench or systemic fungicides, although contact type fungicides are not generally harmful. Insecticides and herbicides that do not hurt the host plant are generally not harmful to FertiZONE’s beneficial inoculants.

Seeded crops: Dilute ten pounds of FertiZONE WP in a minimum of fifteen gallons of water. Apply at a rate of ten pounds of FertiZONE WP per gross acre. If possible, drip the solution directly down the seed line, right on top of the seed before covering with soil. This placement will give the microbes in FertiZONE the opportunity to benefit the plant from the time of germination. If unable to drop the solution on the seed, inject as close to the seedline as possible

Transplants: If using transplant water, dilute 10 pounds of FertiZONE WP in a minimum of fifteen gallons of water. Inject ten pounds per acre as close to the transplants as possible. If using transplant water, apply the solution through the transplant rig, if hand planting, dip the transplants into the solution and plant immediately.

Trees and vines: Dilute FertiZONE WP in a minimum of 25 gallons of water. Use a pump driven injector to put the solution directly into the root zone of the plant. Prior to injecting, use an 8 ounce container and note the amount of time it takes for the pump to fill the container. This will be the standard amount of time necessary for an injection. For large plants like mature trees, inject 5 to 15 times within the drip line of the tree. For smaller plants, like vines, inject one or two times on each side of the vine.

FertiZONE Granular

General Information: For maximum benefits, use with lower analysis fertilizers. Avoid the use of semi drench or systemic fungicides, although contact type fungicides are not generally harmful. Insecticides and herbicides that do not kill the host plant are generally not harmful to the FertiZONE Granular soil improver beneficial inoculants.

Seeding and Potting: Mix with potting or seeding mix at the rate of 2 to 4 lbs. per cubic yard of mix.

Row crops: Apply directly on the seed or in transplant hole, at planting, at a rate of 5 to 25 lbs. per acre.

Vegetable crops: tomatoes, peppers, potatoes, lettuce, broccoli, celery, squash, onions, garlic, eggplant, cucumbers, beans, sweet corn, herbs.

Specialty crops: sugar cane, sugar beets, strawberries, raspberries, blueberries, bananas.

Tree crops & vines: apples, peaches, pears, apricots, papayas, bananas, cherries, plums, prunes, avocados, oranges, grapefruit, lemons, limes, melons, grapes, kiwi.


General Information: FertiBOOST WP should be diluted in water to ensure uniform coverage and to prevent leaf damage. FertiBOOST WP may be applied through drip, sprinkler, and flood or furrow irrigation.

Soil application: Apply at a rate of 1 to 2 lbs. per acre, dissolved in appropriate amount of water for complete coverage. Apply 1 to 6 times depending on crop economics and growing conditions. Time the applications about 1 month apart.

Foliar application: Apply at a rate of 1 to 2 lbs. per acre dissolved in 20-40 gallons of water. Apply 1 to 6 times per crop per growing cycle. Apply late in the day to avoid excessive heat. Temperature should be below 90° F at application. Irrigate normally following application.



Metagrow Compost Teas can be applied through most irrigation systems, in transplant water, preplant seed treatment, dribbled over a seed line at planting, side dressed, sprayed on a berm, or water run in furrow irrigation. See product filter mesh size at the bottom of the label for application method compatibility. Use rates will vary from 2 gallons per acre up to 5 gallons per acre, depending on crop, the number of applications, and application timing. If injecting into an irrigation system, irrigate normally injecting the desired rate of Compost Tea. With other application methods, dilute the Compost Tea with 4 parts water (or more) for each part of Compost Tea. When soil applied, follow the application with additional water to ensure the Compost Tea is washed into the soil.


 Tree and Vine Rooting

CropBioLife Application Rates

CropBioLife is generally applied at a rate of 3-4 ounces per acre for vines, shrubs and trees. Row crop general application rates are 1 ml of CropBioLife per 1 liter of water. Minimum application is 3 times per crop cycle and can be as many as 6 times per crop cycle including post harvest applications


Earthworm Organics

Vermigrow Stable Compost Tea contains a one..two punch. First is the immediate effect of the metabolites and second are the benefits from an increased and diverse microbial population. We typically advise adding .5-1 lb. of FertiBOOST to the application of the compost tea as it provides more raw
materials for the microbes as they awaken. Application rate is 3-5 gallons per acre with 4-6 applications throughout the growing season.
