how to use super absorbent polymer in agriculture?
Chinafloc-sap is a high performance super absorbent polymer based water retainer scientifically formulated using an innovative cross-linked co-polymer of acrylamide and potassium acetate.
Chinafloc super absorbent polymer has a range of applications but is primarily used as a highly effective water retainer for soils and substrates in farming, agriculture and horticulture.
Chinafloc-sap is a highly efficient polymer based water retainer that, when incorporated into a soil or a substrate will absorb and retain large quantities of water and nutrients. Unlike most products that become hydrated, Chinafloc-sap can easily release absorbed water and nutrients, thereby allowing crops to access the water and nutrients available at will, as a function of the absorption and release cycles.
1.Chinafloc sap is a kind of potassium SAP.you can find at least 7 different SAP like sodium ,polyacrylamide sap or cross-linked copolymer and others ,but they are not the real SAP ,it is harmful to the plants and the price is very lowder. potassium SAP is the only suitable SAP for agriculture.
2.The colour of our SAP is brown,it is the only brown colour SAP in china market.becasue we add a nature soil in it with some microelements in it like N,K,P.
3.how to judge if the supplier have the qualify for production of SAP for agriculture in China?just ask for a license of fertilizer .if the supplier can not supply it ,that mean this supplier can not produce SAP for agriculture.
Benefits of Chinafloc-super absorbent polymer
· High performance super absorbent polymer based water retainer.
· Increases the water holding capacity of soils for several years.

DBH: diameter at breast height
3)Adult tree
Dressing:The canopy projection shall prevail,digging circular furrow or strip furrow along the edge of projection, (width:10-15cm depth: To expose the partial root shall prevail),Mixing SAP and soil which is 10cm from ditch bottom, then fertilize into ditch, filling the ditch after irrigation. If fertilizing with fertilizer, fertilizer should be above SAP, fertilizer and SAP should be separated by soil.
