The Effect of Whey-Based Hydrogel Addition on Soil Water Holding Capacity and Availability of Nutrients

Popis výsledku v původním jazyce

The paper is focused on testing the effect of whey-based hydrogels on chemical and physical soil properties. Prepared hydrogel analysed and its potential impact on soil properties was assessed in a pot trial. The artificial soil, suitable for pot experiment, was selected. The necessary volumes of soil were prepared in the laboratory. A control and three hydrogel variants were studied. In the next phase, pot trial was set up; subsequently soil samples were taken from the different variants. The samples were analysed by accredited methods in the Research Institute for Soil and Water Conservation. By adding the elements important for plant nutrition, whey hydrogels can directly contribute to plant nutrition both by directly adding microelements to the soil and by increasing binding sites and can be economically helpful in reducing the cost of further nutrition of plant production. Our results showed the perspective of whey-based hydrogel for practical use in agriculture because the natural nutritional benefits of agricultural utilization of whey are enhanced by water retention abilities via the chemical cross-link of whey with citric acid. In the soil experiment, the positive effects of 1%, 2%, and 3% hydrogel addition on both water-holding properties and the temporal availability of nutrients were determined.
