FORTA is a high-quality micronized calcium sulfate powder derived from Diamond K mined gypsum. Naturally rich in calcium and sulfur, it supplies two essential plant nutrients that support strong growth, soil structure, and overall crop performance.
Designed for drench, foliar, or top-dress applications, FORTA helps maintain calcium availability throughout the growing cycle while supplying sulfur for important plant metabolic processes.
Ideal for growers looking to strengthen plant structure, support healthy development, and supplement calcium and sulfur without adding nitrogen.
Provides readily available calcium and sulfur
Supports strong plant cell walls and structural growth
Promotes healthy root and shoot development
Helps maintain balanced plant nutrition
Supports improved soil structure and aggregation
Provides calcium without adding nitrogen
Suitable for use throughout vegetative and flowering growth
Drench:
Mix 1/4–1 teaspoon per gallon of water. Apply weekly or every two weeks as needed.
Foliar Spray:
Mix 1/4–1 teaspoon per gallon of water. Apply weekly as needed.
For liquid applications, mix thoroughly before use. Maintain agitation when possible to keep the micronized powder evenly suspended.
Top Dress:
Apply 1/2–1 teaspoon per gallon of growing medium as needed. Spread evenly across the surface, work in lightly, and water thoroughly. Use a soil test to determine the most appropriate rate and frequency.
Suitable for vegetative, flowering, and perennial crops.
FORTA acts as a concentrated source of calcium and sulfur, helping to:
Support strong plant cell walls and tissue development
Maintain healthy structural growth
Supply sulfur for enzyme, protein, and chlorophyll production
Support root-zone nutrient balance
Improve the physical structure of suitable soils
Supplement calcium without adding excess nitrogen
Best used as part of a balanced fertility program wherever additional calcium and sulfur are required.
Guaranteed Analysis:
Total Calcium (Ca): 22.5%
Total Sulfur (S): 18.0%
Calcium Sulfate Dihydrate: 97.0%
Form: Micronized calcium sulfate powder
Source: mined gypsum
Application: Root drench, foliar spray, or top dress
Use Case: Soil, soilless growing media, gardens, field crops, and container plants
Compatible with many nutrient and soil-amendment programs.
Because calcium may react with certain concentrated fertilizer ingredients, avoid combining FORTA directly with concentrated phosphate solutions. When mixing with other products, add each ingredient separately to water and perform a small compatibility test before preparing a full batch.
Use adequate agitation and check application equipment to prevent settling or clogging.
Store tightly sealed in a cool, dry place away from humidity and direct sunlight.
Avoid inhaling dust; wear a suitable dust mask during handling. Avoid contact with the eyes and skin. Do not ingest. Keep out of reach of children and animals.
