Hydrogel Polymer Improves Agrophysical Properties of Soil

Mar 29, 2022

By David Bradley

Arid regions of the world have always struggled to grow crops but climate change and drought coupled with stronger winds can lead to a greater rate of soil erosion exacerbating the problem. Work in the International Journal of Agricultural Resources, Governance and Ecology, looks at how the problems facing horticulture might be addressed with the use of innovative technology

Alevtina Danilova, Andrey Vinokurov, and Elena Isakova of the Altai Botanic Garden part of the Kazakh Academy of Sciences in Leninogorsk, and Naziya Suleimenova and Yerzhan Abildaev of Kazakhstan National Agricultural University in Almat, Kazakhstan, have focused on a group of fruit trees and other trees and shrubs grown in the arid South-East and East Kazakhstan. They have investigated the water-saving potential of an absorbent hydrogel polymer "AQUASORB," which can improve the agrophysical properties of soil. Aquasorb is a polyacrylamide that can absorb 400 times its own weight in water. The soluble material has been used elsewhere to flocculate irrigated soil, which improves water penetration, soil aeration, and reduces soil erosion.

Video: EP 73 Diversity is Resiliency – Stories of Regeneration Part 6

During the growing season of 2023 as summer turned into fall, the Rural Routes to Climate Solutions podcast and Regeneration Canada were on the final leg of the Stories of Regeneration tour. After covering most of the Prairies and most of central and eastern Canada in the summer, our months-long journey came to an end in Canada’s two most western provinces around harvest time.

This next phase of our journey brought us to Cawston, British Columbia, acclaimed as the Organic Farming Capital of Canada. At Snowy Mountain Farms, managed by Aaron Goddard and his family, you will find a 12-acre farm that boasts over 70 varieties of fruits such as cherries, apricots, peaches, plums, pears, apples, and quince. Aaron employs regenerative agriculture practices to cultivate and sustain living soils, which are essential for producing fruit that is not only delicious but also rich in nutrients.
