GREAT ROOT is a functional fertilizer developed using SOBEL’s proprietary Black Links® technology. It is rich in six highly active functional groups: quinone, carboxyl, hydroxyl, phosphate, amine, and methoxy. SST delivery technology enables rapid delivery to the areas around capillary and main roots, resulting in high absorption and utilization by crops.

Main Crops: Grapes, greenhouse cucumbers, sweet tomatoes, peppers, citrus, potatoes, rice seedling beds, strawberries, watermelons, melons
Application Method: Throughout the entire growth cycle, use 75~150L/ha via drip irrigation or fertigation, or dilute 300~400times for root irrigation.
1.Blacklinks® Technology for Comprehensive Stress Resistance
2.SST (Smart Nutrient Delivery System) Technology to Directly Target Root Systems
Surface Tension and Contact Angle Reduction for Rapid Spreading
3.Added surfactants enable uniform lateral distribution
Incorporation of polymeric alcohol surfactants synergizes with modified functional groups, ensuring effective expression of active ingredients while facilitating rapid movement and uniform distribution throughout the tillage layer.
4.Small particle size enhances soil penetration, diffusion, and crop absorption
4 molecular-level certifications for optimized crop uptake—GPC, FA/HA, Humic acid E4/E6, H/C ratios.
GPC Value FA/HA Value
Note: GPC is a liquid chromatography-based technique for analyzing polymer molecular weight distribution, serving as a critical method for macromolecular characterization.
Humic Acid E4/E6 H/C Value
5.Soil Column Leaching Test
GREAT ROOT demonstrates higher HA content across all soil layers versus controls and competitors, with total HA accumulation concentrated at 2.5–20cm depth (primary root distribution zone of crops).
