Environmentally Friendly Carboxymethyl Cellulose Hydrogels Derived from Waste Paper and Sawdust as a Urea Release Agent.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study investigates the development and application of cellulose hydrogel-based slow-release fertilizers derived from waste materials, specifically waste paper and sawdust, in cultivating water convolvulus. The slow-release fertilizers were created using carboxymethyl cellulose (CMC) derived from these waste sources with citric acid as a cross-linker, aiming to enhance nutrient efficiency and sustainable agricultural practices. The CMC hydrogels demonstrated high water swelling-approximately 10 times its dry weight, enhancing soil moisture holding levels across different soil types. Notably, the slow-release fertilizer derived from sawdust (HyU_CMC_SD) showed the highest urea absorption (330.8 ± 2.3 mg/g) and a high urea release rate in water and soil owing to its polymeric chain property. Cultivation trials over 25 days revealed that water convolvulus grown with the sawdust-derived slow-release fertilizer had the most extended stem growth, while the slow-release fertilizer from waste paper (HyU_CMC_P) provided gradual, more prolonged release, supporting consistent plant growth post-14 days of growing. Overall, slow-release fertilizers from the CMC hydrogels proved effective in slowing nutrient release, conserving soil moisture, and minimizing nutrient leaching. This research suggests that cellulose hydrogel-based slow-release fertilizers from waste materials offer a promising approach for sustainable and efficient agricultural production.
