Abstract:
With the growth of the global human population, the demand for agricultural products has increased. The increased yield is a result of the application of agrochemicals and advanced technologies. Excessive use of agrochemicals leads to environmental pollution and endangering human health, so more and more attention is focused on the proper and controlled cultivation of crops in agriculture. In this work, three types of polyurethane hydrogels were synthesized and the structure was examined by Fourier transform (FTIR) infrared spectroscopy, differential scanning calorimetry (DSC), swelling rate, and plant culture growth with and without hydrogels on tomato crop culture were monitored. Fertilizers are water-soluble systems that hydrogels can absorb and later release into the soil along with water. The results of monitoring the crop showed that the application of hydrogels with the controlled release of fertilizers has an extremely favorable effect on the tomato crop.

Key words:
