Along with nitrogen, phosphor and potassium, sulfur is the fourth obligatory component of mineral manures.

In the 1970s companies in Canada and the USA started to produce sulfuric bentonite in the form of granules with dimensions of about 4mm and consisting of a bentonite core and a sulfur covering. After application and watering, water reaches the core, the core expands by 7-11 times and breaks the covering into small particles. Owing to the high surface area of sulfur particles, sulfur passes into soluble forms, which are well digested by plants. Weight composition of grains: sulfur - 85-90% bentonite - 10-15%.

Tests of these Canadian manures conducted in 2002-2004 showed the favorable result.

Our technology of production of small-grained sulfur allows to produce sulfur in the form of a powder with a high surface area of grains that doesn’t dust and cake as a standard mineral manure. In a standard wet soil small-grained sulfur passes to soluble forms during a day. Grains contain about 99, 9% of sulfur. This solution allows to refuse from the use of sulfur with bentonite, because bentonite disimproves the quality of soils.

Application of manures on the basis of small-grained sulfur has a notable influence on:

1. Protein syntesis. This is of particular importance that such manures improve the quality of protein.

2. Increase of cysteine and mediotine content in wheat and barley.

3. Better drought resistance, cold resistance and resistance to illnesses of plants.

Tests conducted in the last two years revealed that plants set out to the soil with sulfur additives showed the better growth of green material (by 15-20%).
