Product overview
FERTISORB™ is a water-absorbing and water-retaining polymer designed to be compounded, coated or blended with fertilizers to produce organic, compound and slow/controlled-release fertilizers. When combined with fertilizer, it absorbs nutrients and moisture, releases nutrients gradually for plant uptake, reduces leaching losses, and helps save water and fertilizer while improving yield.

Key benefits

• Enhanced fertilizer release: FERTISORB™-231 accelerates granule disintegration and increases fertilizer release speed and use efficiency by 35–65% (application-dependent).
• Improved fertilizer performance: Retains moisture and nutrients to provide a steady supply to crops; improves granule appearance and uniformity.
• Soil structure improvement: Expands in soil to improve permeability and looseness and alleviates compaction.
• Versatile granulation application: Compatible with disc, drum and extrusion granulation processes.
• Environmentally friendly and biodegradable: Biodegrades in soil and supports sustainable use.

Applications / Usage

• Blend with fertilizers (co-application), coat or compound into organic, compound, slow/controlled-release fertilizers.
• Suitable for integration into granulation or bulk blending operations to ensure uniform distribution and consistent field performance.

Practical notes & tips

• FERTISORB™ accelerates fertilizer granule breakdown for timely nutrient availability and early crop vigor.
• Available in multiple mesh sizes for different processing and field needs.
• Typical blend guidance: example field mix 750 kg/ha fertilizer with 30–90 kg/ha FERTISORB™ using professional mixing equipment; adjust per crop and conditions.
• After application, irrigation can activate the polymer and maximize performance.

FAQs (selected)

• Recommended addition rate: 0.2%–2% of total fertilizer weight (2‰–2%); adjust by fertilizer type and needs.
• How to use in granulation: Add to raw materials at the recommended rate, mix thoroughly, then granulate (suitable for disc, drum and extrusion).
• Is it environmentally friendly? Yes — biodegradable in soil.
