Effects of Different Macromolecule Absorbent Resins on the Moisture Characteristics of Major Soil Type on Loess Plateau

“…It can improve the state of soil particles and lower bulk density and improve soil porosity, impact resilience and water retentivity in soil 9 . Although research on PAA has achieved numerous results, most of these papers have focused on the study on the application methods of PAA 10 , effects of fertilizer maintenance 11,12 , comparison of the effects of PAA on water retention and fertilizer maintenance with those of other water holding materials, synthesis of PAA with other new organic and inorganic water retention pharmaceutics 13 and properties of PAA such as water absorption, fertilizer maintenance 14 and salt absorption 15 . Wote super absorbent is an organicinorganic compound water retention agent synthesized using the hybridizing process of polyacrylic acid and attapulgite.…”
