Sylvite’s SGN Scale ensures that your fertilizer application is optimized for consistency and efficiency.
- Accurate Size Measurement: Provides an SGN histogram to classify particle size and ensure uniform blending.
- Prevents Segregation: Helps maintain even distribution, reducing uneven growth and application issues.
- Compact & Easy to Use: Designed with five sieves for quick on-site fertilizer testing.
- Versatile Applications: Available in Agriculture, Fairway, Greens, and Specialty models to match different industry needs.
Particle size plays a crucial role in preventing segregation and ensuring uniform fertilizer application. The Size Guide Number (SGN) represents the median particle size, calculated by multiplying its dimension in millimeters by 100. For example, a fertilizer with an average particle size of 2.40 mm would have an SGN of 240. Below are the specifications for each SGN Scale model.

Frequently Asked Questions
The Sylvite SGN Scale is a tool designed to quickly measure the particle size distribution of fertilizer blends. It uses a series of sieves to determine the Size Guide Number (SGN), which helps ensure uniform application and proper nutrient distribution.
Consistent particle size prevents segregation, ensuring even nutrient distribution across fields, fairways, and greens. Proper sizing reduces uneven application, helping crops and turf receive balanced nutrition for optimal growth.
The right SGN Scale depends on the application. The Agriculture model is ideal for general farm fertilizer blends, while the Fairway model is designed for golf course fairways and large turf areas. For precision applications on golf greens, the Greens model provides the most accurate measurement, while the Specialty model offers versatility across various fertilizer and soil applications. If you’re unsure which model best suits your needs, a Sylvite representative can guide you in making the right choice.
By ensuring proper fertilizer sizing and uniform application, SGN Scales help reduce waste, minimize nutrient runoff, and improve efficiency. This supports sustainable nutrient management practices while helping you get the most value from your inputs.
