What is SAP (Super Absorbent Polymer)?
Super absorbent polymer (SAP) is a polymer material with good water absorption
and water-holding capacity. It can absorb water up to several hundred times of
its own weight, and turn into natural gel from within seconds. SAP can be mainly
divided into three major categories which are Hygiene grade, Agriculture grade
and Industry grade. The main uses of SAP are absorbing, retaining or to block
liquid.
Application
Our SAP are widely used in agriculture, forestry and gardening, such as Soil
water retention agent, seed coating, soil-less cultivation, artificial turf, forest
fire, etc. It applies to water-saving agriculture and forestry in the drought-wide
application prospects.
It is a new functional polymer material: innocuous and can absorb/release
water circularly because of its strong absorption group and special structure
(mesh structure). People usually compare it to ‘mini-reservoir’. Besides, it can
also absorb fertilizer and release them slowly to increase the efficacy. This
product is not only conducive to crop growth, but also conducive to soil
improvement.

Advantage
1. Common plants and crops
15 to 30 kg per acre 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 arid area of inner Mongolia, potatoes grown
in Cape Verde Africa, and potato yield increase more than 2 times.
2. Seed coating
Seed coating use SAP should be fine particle size of 0.3 mm or less,
after SAP coating the seed emergence quickly, strong and good
disease resistance, this is the easy available way use SAP to plants
in drought area, which also with small quantity, low cost and good
performance.
3. Gardening, Horticulture and landscape
SAP is ideal for mixing soil matrix, for indoor and outdoor pots,
planters, window boxes, balconies, terraces, roofs, hanging,
gardens, city landscape. Planting shrub, flower, grass, vegetables
are available. Using SAP can bring water-saving, labor saving,
time-saving benefits and reduce the drought or wilting risk
causing by long time no watering the plants, longer the green
time and the blossom period.
4. Lawn and Golf course
Application in golf and lawn can save about 50%-70% water,
Reduce the cost of maintenance, Save about 30%-50% fertilizer.
Lawn grows faster, healthier, and the green last longer, less
pollution caused by the loss of fertilizer.
5. Trees
SAP as important role like fertilizers, pesticides, it is because
the development of planting saplings and fruit, a continuous
supply of water is very important. Using 10-20g SAP can
double the survival rate of young trees when planting tree
seedlings (bare root)
For adult deciduous fruit trees, put the SAP with organic fertilizer,
taken with a ring groove or furrow in the root area. The dosage is
up on the soil condition, tree size and the ditching situation, should
generally be 0.3% of the backfill soil and fertilizer. Liaoning and
Shandong planting apple in Liaoning and Shandong, lychee and
pineapple in Guangxi, bananas and peaches in Yunnan, get very
good result after using SAP.
