Release characteristics of Scotts
 coated fertilizers
The difference between Resin and Poly-S coating
Poly-S
Moderate influence of temperature on release
Start release high
Urea granules
Resin  coating
Temperature defines release
Start release low
NPK granules
Coumpounds versus straights
Good quality particles
Better to coat
Better quality coating
More choice in raw material
Better nutrient mixture
Less segregation
Poor quality particles
Difficult to coat
Low quality coating
Few raw materials
Poor nutrient mixture
More segregation
Recipe of 15-8-9-2.5
Chemical breakdown of 15-8-17-+2.5
15-8-17+2.5 dummy (straights)
Chemical breakdown of 15-8-17+2.5 dummy (straights)
Segregation is unpredictable
Possible reasons for segregation
Particle size
Particle weight (bulk density)
Particle shape
Particle sphericity
Particle smoothiness
Way of mixing
Methods to detect segregation
Visual method
View, picture
Picking particles
Chemical analyses of samples
