General Information

SoilFuel Plus solution is versatile and can be applied to agricultural and horticultural plants through soil and foliar application. It is compatible with a wide range of farm fertilizers, making it suitable for various crops such as vegetables, cucurbits, field and row crops, deciduous fruit and nut trees, citrus, olives, potatoes, grapes, avocados, berries, etc. The solution can be applied directly to soils or injected through irrigation systems.

Foliar Applications

For foliar applications, SoilFuel Plus solution should be diluted based on specific crop requirements. Dilute 1 gallon (4 liters) of SoilFuel Plus solution in 25 gallons (100 liters) of water before application. Ensure thorough agitation and mixing with water.

Timing of Soil Application

Apply SoilFuel Plus Solution to the soil in the fall or early spring. Multiple applications, up to five per growing season, can provide optimal results.

Water Requirements

Maintain a water pH of no less than 6.5 to prevent fallout. Water with high levels of calcium, especially hard water, is not ideal.
