Assessment of the water content of the soil and utilization of the energy balance model to promote environmental-friendly development of green, low-carbon industries

Abstract The use of energy balance models to study the water content of soil can effectively solve some problems in agricultural production, ecosystem management, and environmental management. The application of the energy balance model requires a large amount of data, and its application in agricultural production is proposed mainly for the prediction and evaluation of the water content of the soil. Various water content values of the soil were determined using an energy balance model and an oven-drying method. The natural water content of the sandy soil determined by oven drying was between 30 and 40% for the sample soil from the same batch, with the second sandy soil sample having the highest value of 39.2% and the 15th sandy soil sample having the lowest value of 30.3%. The natural water content of sandy soils determined using an energy balance model was between 30 and 35%, among which, the natural water content of the fifth sandy soil sample was the lowest at 30.12% and the natural water content of the third sandy soil sample was the highest at 34.46%.
