General Application Rate

Apply 15–30 L/ha throughout the growing season. Apply 8–15 L/ha per application during planting or after transplanting, before flowering, and after fruit set and fruit development. For perennial crops, apply after flowering.

Orchard and Ornamental Crops

Soil Application (Drip Irrigation)

Orchards and Flowers:
Apply a total of 20–30 L/ha weekly during the growing season, starting 7–10 days after planting. Begin with 3–6 L/ha after transplanting, then gradually reduce to 1.5–3 L/ha toward the end of the growth cycle.

Flood Irrigation:
Apply a total of 25–30 L/ha divided into 4–5 applications. The first application should be made a few days after planting or 7–10 days after transplanting, followed by applications during peak vegetative growth, flowering, fruit set, and fruit development.

Broadcast Application:
Apply 20–25 L/ha during the early growth stages (before, during, or immediately after planting or transplanting) using a minimum of 200 L of water per hectare.

Band Application (e.g., along planting rows):
Apply 25 L/ha during the early growth stages (before, during, or immediately after planting or transplanting) with a minimum of 200 L of water per hectare.

Perennial Crops

(Fruit Trees, Citrus, Banana, Grapevine, Olive)

Drip Irrigation:
Apply a total of 25–35 L/ha every 2–3 weeks, beginning at bud break.

Sprinkler Irrigation:
Apply a total of 30–40 L/ha, divided across several applications.

Field Crops

(Maize, Sugar Beet, Alfalfa, Potato, etc.)

Apply 10–20 L/ha through irrigation.

Growing Media Enrichment

Mix 3–5 L per 1,000 L of growing substrate.

Seed Treatment

Apply 0.5–1 L per 100 kg of seed.

Compatibility

Compatible with most commonly used agricultural products, except calcium nitrate, mineral oils, acidic formulations, and herbicides incompatible with organic compounds. A compatibility test is recommended before mixing.
