Program calendars, application calculators, product data, soil science and downloadable guides for the Sigma Foundation Program, built on GCSAA best management practices.

Where it's manufactured
From raw material to finished granule. Every Foundation Program product is manufactured in our granulation plants and packaged in our packaging facilities, ready for the course.
We source natural raw materials and check them against Sigma specifications before they go into production.
Two granulation plants formulate and manufacture each product into a consistent granule, with quality control checks throughout production.
Finished product is packaged in our packaging facilities and shipped to the course, ready to spread.
Each market uses the same agronomic framework. What changes is the scheduling logic: playing surface on a golf course, the competition schedule on a sports field, service rounds in lawn care, production stages on a sod farm.
Sigma's agronomic programs team includes former golf course superintendents and turf agronomists. Every calendar starts where turf performance starts: rooting, soil structure and the biology in the root zone.

Every product use is tied to a soil test, a trigger and a measurement.
Reviewed against product labels and piloted before release.

One row per application event. Products with different handling get their own rows. Nothing goes on the calendar without a reason to apply it and a way to measure the result.
Soil temperature, growth stage, weather or event schedule.
What the application is meant to change.
Aerification, topdressing, mowing, irrigation and traffic work that goes with it.
Selected only where nutrient need or a defined purpose supports it.
Per 1,000 ft² for greens, tees, fields and lawns; per acre for fairways and rough.
Days or weeks to the next event, or once.
Spreader or spray volume, tank mixing, irrigation after application.
How it fits the conventional fungicide, herbicide, insecticide and PGR plan.
GCSAA's national initiative asks every facility to document its BMPs. Each Sigma calendar row is tagged with the BMP area it supports, so a program can be referenced directly in your facility plan.
