Super Absorbent Polymer, also known as SAP, is a hydrophilic polymer with a three-dimensional network that has the ability to absorb and retain a large amount of water and aqueous solutions, even under pressure; In general, a superabsorbent is a dry, usually sugar-like substance with the ability to absorb water and some dissolved substances several times its weight; Superabsorbent powder has 4 different meshes (granulations), which are available to farmers and gardeners based on the advice of experts according to different conditions such as type of cultivation, soil texture, climatic conditions, etc.

The structure of these materials is such that they can absorb, retain water and dissolved substances for several years under ionic conditions, pressure, soil microorganisms, like a reservoir, and provide them to the plant according to the needs of the roots (due to the difference in osmotic pressure).

The superabsorbent never returns to its original materials and the reactions of this polymer are completely non-toxic. These polymers are organic materials that slowly decompose under the ionic and microbial conditions of the soil and are eventually converted into water, carbon dioxide, and non-toxic nitrogenous compounds, including ammonia, and added to the soil organic matter.

• The permeable superabsorbent comes in two forms: dry powder and hydrogel (soluble in water). It is placed next to the roots. In agriculture, it is used by row-work machines and in gardening, when planting seedlings or in fertilizer pits next to planted trees.
  • Use for fruit trees
  • Herbaceous and cultivated plants
  • Rainfed cultivation
  • Non-fruitful trees
  • Green spaces, lawns and golf courses
  • Seedling relocation
  • Hydroponics

The permeable superabsorbent with ion exchange properties of 450-480 milliequivalents per 100 grams has the highest percentage of nutrient absorption, which reduces fertilizer and nutrient consumption by up to 35%, and absorbs all mineral, animal and chemical fertilizers added to the soil and desorbs them when needed by the roots.

Due to the presence of potash in the permeable superabsorbent formulation, this material is a very complete nutrient for plants and soil in itself.

The permeable superabsorbent is produced from biodegradable and completely neutral polymers that, after being used in the soil, decomposes through the reaction between soil microorganisms and turns into potash fertilizer. As a result, the use of permeable superabsorbent in the soil, in addition to improving the soil structure, causes root formation and, due to the swelling of the permeable superabsorbent grains, causes root ventilation and prevents the growth of fungi.

The permeable superabsorbent has been used in dryland wheat cultivation in Kermanshah Province, irrigated wheat cultivation in Tehran, Varamin region, chickpea and bean cultivation in Zanjan, cotton cultivation in Gorgan, irrigated rice cultivation in Sepidan, Fars, potato cultivation in Kabutar-Ahang, Hamadan, used in lawns in Khuzestan Province, and the green spaces of the petrochemical industry in Omidieh County, Isfahan Steel Complex, and chemical industries, as well as in pistachio, citrus, olive, grape, etc. orchards, and in summer greenhouses and seedling and transplant production.

The use of permeable superabsorbent in agriculture and horticulture is very small, but it has a long life in the soil.

Due to the retention of water in its grains next to the plant roots, the absorption of nutrients and the prevention of leaching, and as a result, the constant presence of nutrients and abundant water next to the roots, the permeable superabsorbent increases crop yield and reduces the consumption of fertilizers and nutrients.

The most notable function of superabsorbent in dry and low-rainfall areas and during irregular rainfall is to conserve water and provide normal yield to dear farmers.
