Potassium polyacrylate, also known as TRUE HYDROGEL, is a potassium salt of polyacrylic acid that functions as a water-retaining polymer. It can be applied dry by mixing 2-5 kg of TRUE HYDROGEL per cubic meter of backfill soil or 5 grams per liter of smaller soil quantities. TRUE HYDROGEL can also be used wet by dipping plant roots in a prepared solution before planting or in greenhouses by mixing 1-3 g of TRUE HYDROGEL per liter of growing substrate. For broadcast application, TRUE HYDROGEL is mixed into soil at a depth of 10 to 15 cm at a recommended rate before seeding or planting
