Suståne Means Compost
Intentional, Stable, Predictable

Product quality and consistency are Suståne’s first objectives toward achieving total customer satisfaction. For any product to be accepted AND successful in today’s market, it must provide efficacy, efficiency, safety and cost- effectiveness. Without these four criteria satisfied, one is simply producing just another product to fill the marketplace. Suståne staff are passionate about the job we do and the products we offer. The goal is simple: To produce the best organic on planet. With that, Suståne is one of the few organic fertilizer companies that is basic in its manufacturing. This means that Suståne controls the raw materials, the composting process and manufacturing process from start to finish. Unlike many of the other “organic fertilizer” companies Suståne is not simply a marketing company that purchases finished product from toll manufacturers, wraps it in fancy packaging and hypes it with generalized platitudes about how good it is. Suståne operates its own full time, in-house analytical chemistry lab. Every product is tested to assure that it meets the labeled guarantee, uniformity and safety. Periodically samples of finished product are sent out to independent certified analytical labs to assure that the Suståne methods and equipment are producing accurate test results. And, Suståne retains product samples from every lot manufactured for up to two years after shipment, complete with production logs and ingredient samples. If there is ever a question about the integrity of the Suståne product used in the field, the customer can call to inquire or ask for a split sample or retest of the same lot number. It is because of this attention to quality assurance and product safety that Suståne is the only organic fertilizer allowed for export worldwide. You can count on the Suståne commitment to quality. |

to what some popular
For the Suståne process to be complete 50 separate turning or aeration events are required over a 26-week time period. Total biological stabilization produces a consistent, uniform predictable biomass. The finished compost is the base material from which all Suståne natural fertilizers are built. This attention to process detail, along with uniform parent materials, creates organic fertilizers that safe to use and provide reproducible results in the field every time. We measure compost maturity or compost stability, in addition to continuous on-site temperature monitoring and record keeping Suståne routinely performs two analytical tests that provide objective measurements of compost maturity. The Solvita Compost Stability Analysis and the Dewar Self-Heating Flask Test. |

Solvita® by Woods End® Research The Solvita® test gives the Maturity Index for a sample of compost by measuring carbon dioxide respiration and ammonia content. Compost is placed inside a jar with two separate color- indicator “paddles” (one measuring carbon dioxide and one measuring ammonia). After four hours, the gel color is read by comparing the color to the provided color charts. Values are referenced on the tables provided and maturity is determined. Maturity is defined by resistant to further decomposition and free of compounds such as ammonia and organic acids, which can be toxic to plant growth.

Dewar Flask Test The Dewar Flask test was first developed in Germany as a simple, reliable means to determine relative compost maturity. After placing a sample of compost inside the flask the temperature is measured over a 3-10 day time period to determine the rise in temperature before declining for at least two days after the maximum is reached. Based on the difference between the highest temperature minus the ambient temperature, the compost is rated into five classes ranging from fresh, raw compost to stable finished compost. Test run between September 14 – 19, 2001 on Suståne compost showed a temperature rise of 2o F for a result of Class V = Stable, Finished compost. |
