controlled-release
Controlled-release technology involves the gradual and prolonged delivery of agricultural inputs—such as nutrients, pesticides, or growth regulators—to plants over an extended period rather than in a single application. This approach is critical in plant science because it synchronizes nutrient availability with plant uptake rates, reducing losses from leaching and runoff while minimizing environmental contamination. By improving nutrient efficiency and reducing application frequency, controlled-release systems enhance crop productivity and sustainability while lowering overall input costs.

Researchers developed an eco-friendly fertilizer nanocomposite using cellulose fibers extracted from pineapple peel waste, combined with biodegradable polymers and natural fertilizers. In field trials, the optimized formulation (F1) significantly boosted plant growth and improved nutrient absorption while reducing environmental pollution.
Microwave-assisted extraction of cellulose nanofibers from pineapple peel achieved 40.86% yield, outperforming high-speed blending at 33.21%
Formulation F1 with optimized cellulose nanofiber content improved plant height up to 182.4 cm and leaf area up to 530 cm² compared to controls
The nanocomposite demonstrated enhanced biodegradability, water retention, and controlled nutrient release in both conventional and vertical farming systems
