The "Green Revolution" of White Carbon Black in Agriculture
Pesticide efficiency enhancement:
Suspension agent stability: White carbon black acts as a disintegrant, increasing the suspension rate of 75% atrazine water dispersible granules from 75% to 95%, with no clumping after 14 days of thermal storage (54 ℃).
Extended shelf life: After adding 10% white carbon black to imidacloprid, the half-life on leaves was extended from 7 days to 21 days, with a 40% increase in efficacy.
Fertilizer Innovation:
Slow release carrier: White carbon black coated urea, nitrogen release cycle extended from 30 days to 90 days, utilization rate increased from 35% to 55%.
Trace element chelation: After loading iron fertilizer with white carbon black, the absorption rate of crops is three times higher than that of traditional ferrous sulfate, and the cure rate of yellow leaf disease is 90%.
Soil improvement:
Water retention and drought resistance: White carbon black/polyacrylamide composite material, with a water holding capacity of 500 times its own weight, can increase crop survival rate by 60% under drought conditions.
Saline alkali treatment: White carbon black reduces soil pH by 0.5-1.0 through ion exchange, increasing sunflower emergence rate from 40% to 85%.
