Renisco KCS 68 is a clay-coated, controlled-release potassium sulfate fertilizer granule containing approximately 68% K₂O equivalent. The clay coating regulates potassium release, aligning nutrient availability with plant uptake over an extended period. This minimizes leaching and enhances nutrient-use efficiency. Renisco KCS 68 is widely used in horticulture, agriculture, turf management, and specialty crop production.

Description

 

Primary Uses

Agriculture & Field Crops
Provides essential potassium supply for crops like corn, wheat, soybeans, and cotton.

Enhances plant stress resistance, improved yield, and quality.

Reduces soil salinity impact by replacing chloride-based potassium sources.

Horticulture & Specialty Crops
Used in fruit trees (citrus, apple, stone fruits), grapes, berries, and vegetables.

Promotes fruit size, flavor, sugar content, and shelf life.

Applied in sustained-release programs for consistent nutrient delivery.

Turf & Ornamental Plantings
Used in golf course greens, sports fields, and ornamental landscapes.

Supports turf strength, drought tolerance, and uniform color.

Ideal for slow-release fertilization to reduce burn risk and runoff.

Secondary Uses

Controlled-Release Nursery Media
Incorporated in potting soils and nursery mixes to provide prolonged potassium supply.

Reduces frequency of nutrient application in containers.

Greenhouse Production
Used in greenhouse bedding plants and container-grown ornamentals where consistent nutrient release is desirable.

Golf Course & Landscaping Projects
Applied in maintenance of EMBANKMENTS and MITIGATION plantings requiring slow-release nutrition.
