In general, the finer the polymer particle size, the greater its capacity and speed of absorption and vice versa. When applying Tramfloc® 1001A, the 0.1-0.5 mm product, Tramfloc® 1001, the 1 mm product, Tramfloc® 1002, the 2 mm product or Tramfloc® 1004, the 4 mm product, to very porous soils such as sand or compost, use a smaller particle size, Tramfloc® 1001, for more rapid water absorption. In heavy soils such as clay, use the two larger particle size products, Tramfloc® 1002 or 1004. These granules improve the porosity of the soil due to their great expansion capacity. In preparing of dressings, use Tramfloc® 1001 to achieve adequate protection of the root hairs.
