PVOH in Agriculture Applications

The physical and chemical properties are what make polyvinyl alcohol very versatile and ideal for use in agriculture. It features water-solubility, excellent film forming characteristics, high tensile strength and elasticity, as well as resistance against organic solvents and dispersing power and is inherently biodegradable in water/soil in aqueous solution form. PVOH can be used in a wide range of agricultural applications.

Applications

Soil improver


Soil improver

Polyvinyl alcohol is used for improving soil structure and soil fertility. The polyvinyl alcohol can be either be mixed into the soil or sprayed onto the soil as a solution. The goal is to create a crumb structure to the soil, like this the roots can penetrate the soil more easily. With a crumb structure some parameters are improved, creating a good environment for soil organisms. These include water retention, drainage and good air permeability.


Biodegradable and microplastic free solution

Polyvinyl alcohol (PVOH) is recognized as one of the very few vinyl polymers which are water soluble and inherently biodegradable in water in the presence of micro-organisms. The biodegradability of PVOH is affected by its specification or biodegradation condition.
