10-10-20 Controlled-Release Fertilizer Description
Risso’s 10-10-20 controlled-release fertilizer is engineered to deliver a balanced and consistent supply of essential macronutrients—nitrogen (N), phosphorus (P), and potassium (K)—critical for optimal plant development. Leveraging advanced polymer-coated slow-release technology, this fertilizer ensures nutrient availability aligns precisely with crop demand, maximizing nutrient use efficiency while minimizing losses from leaching or volatilization.
This product is ideally formulated for diverse agricultural and horticultural applications, including high-value vegetable production, ornamental landscaping, turf management, and fruit tree cultivation. By choosing Risso 10-10-20, growers benefit from enhanced crop vigor, yield stability, and reduced environmental impact.
Key Features & Benefits of Controlled-Release Fertilizer
Balanced Macronutrient Profile (N-P-K 10-10-20): Provides a synergistic ratio tailored to support vegetative growth, root establishment, and fruit development. This balanced formula is ideal for sustained growth cycles across various crops.
State-of-the-Art Controlled-Release Coating: Utilizes a premium polymer or polymer–sulfur composite coating that regulates nutrient release based on soil moisture and temperature, ensuring a steady nutrient supply over 2 to 4 months.
Enhanced Nutrient Use Efficiency (NUE): Significantly reduces nutrient losses due to leaching and volatilization, improving fertilizer uptake by plants and lowering the risk of environmental contamination.
Environmental Compliance & Sustainability: Meets international quality standards (including AAPFCO and CEN) with a controlled nutrient release profile—less than 15% release in the first 24 hours and up to 75% release after 28 days—aligning with global sustainability goals.
Labor-Saving Application: Prolonged nutrient release reduces application frequency, cutting down labor costs and enhancing operational efficiency for large-scale farming and landscaping projects.

Recommended Applications & Crop Suitability
Vegetables & Greenhouse Crops: Ensures balanced nutrient supply throughout growth phases, promoting healthy leaf development, strong root systems, and consistent flowering and fruiting.
Ornamental Plants & Landscaping: Sustains vibrant foliage and flowering with minimized risk of fertilizer burn, suitable for both containerized and in-ground applications.
Turfgrass & Lawn Care: Provides long-lasting greening effect and wear tolerance, enhancing turf resilience and aesthetic quality.
Fruit Trees & Vineyards: Supports balanced vegetative growth and fruit quality, optimizing yield and crop uniformity.
Usage Guidelines & Best Practices
Soil Testing: Conduct pre-application soil analysis to tailor application rates and maximize fertilizer efficiency.
Application Rates: Generally recommended at 200–400 kg/ha for field crops; adjust rates for containerized plants based on volume.
Timing: Apply at planting or early growth stages. For extended growth cycles, a mid-season supplemental application can be considered.
Application Method: Apply evenly and incorporate lightly into the soil; irrigation post-application is recommended to activate nutrient release.
Storage: Store in a cool, dry environment away from direct moisture and sunlight to preserve coating integrity and nutrient efficacy.
Controlled by diffusion through the polymer membrane, ensuring gradual and synchronized nutrient availability.
