SAP is a new functional material with good water absorption and water-holding capacity.
We can use it to absorb, retain, or block liquid – SAP can absorb water up to hundreds of times its own weight and turn to water gel.
As an eco-friendly material, it is totally non-toxic, harmless, and nonpolluting.
Agriculture grade SAP is just like a “Mini-reservoir”: absorbs the water when it is raining and releases water back when it is dry.
-improve seed germination & emergence, give plants an early, healthy start;
-contains Potassium 18.3% and releases the fertilizer efficiency slowly;
-save the irrigation and improve the soil water holding capacity by 85% (for sand);
– increase crops and fruit yield by 70% (for melon planting in California).
Agriculture grade SAP consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by cross-linking agents, thus forming a network.
When water comes into contact with one of these chains, it is drawn into the molecule by osmosis. Water rapidly migrates into the interior of the polymer network where it is stored. That’s how SAP powder turns to water gel.
As this water gel’s absorption ability is bigger than soil but less than the roots of plants, the absorbed water by SAP will be released to plants when it is dry.
Tips: the specific retention of agriculture SAP is 1.3-1.4 MPa and the specific retention of roots is about 1.6-1.7 MPa.
Common plants and crops
15 to 30 kg per Hectare dosage, along with seeds hole application or ditch application to the soil around the seed, the seed germination rate can effectively improve and promote seedling growth. Gets success planting corn in the U.S, pature in the arid area of Inner Mongolia, potatoes are grown in Cape Verde Africa, and melon yield increased more than 70%.
Seed coating use SAP should be a fine particle size of 0.3 mm or less, after SAP coating the seed emergence quickly, with strong and good disease resistance, this is the easily available way to use SAP for plants in a drought area, which also with small quantity, low cost and good performance.
Gardening, Horticulture, and landscape
SAP is ideal for mixing soil matrix, indoor and outdoor pots, planters, window boxes, balconies, terraces, roofs, hanging, gardens, and city landscapes. Planting shrub, flowers, grass, and vegetables are available. Using SAP can bring water-saving, labor-saving, and time-saving benefits and reduce the drought or wilting risk caused by a long time no watering the plants, longer green time, and the blossom period.
Lawn and Golf course
Application in golf and lawn can save about 50%-70% water, Reduce the cost of maintenance, and Save about 30%-50% fertilizer. Lawn grows faster, and healthier, and the green lasts longer, with less pollution caused by the loss of fertilizer.
Using 10-20g SAP can double the survival rate of young trees when planting tree seedlings (bare root).
For adult deciduous fruit trees, put SAP with organic fertilizer, taken with a ring groove or furrow in the root area. The dosage is on the soil condition, tree size, and the ditching situation should generally be 0.3% of the backfill soil and fertilizer.
