Measuring soil moisture is important for agriculture, as it allows you to optimize planting times, plant cultivation technologies and improve yield and product quality. More accurate and efficient use of water resources reduces the need for the use of chemical fertilizers, which in turn contributes to the preservation of ecological sustainability of agriculture. In order to ensure the sustainable development of crop production, there is an urgent need to introduce the technology of remote sensing of soil parameters into the practice of precision farming.

The purpose of the work is to obtain more complete information about the distribution of moisture on the earth's surface and at different depths of the productive soil layer for remote determination of the portrait of soil moisture. Observation of the dynamics of weather conditions at various time intervals at the ARRIRL research site in test mode.

The article describes the development and experimental use of a complex installation for radiometric remote determination of soil moisture portraits and weather monitoring at the landfill. The article presents the results of experiments conducted at the landfill for several months. The complex installation consisted of a radiometer, meteorological sensors and a data recording system. The data obtained will allow us to clarify the radiation and humidity characteristics of the soil.

Thanks to the introduction of methods for remote determination of the portrait of humidity and temperature of soils, a significant increase in labor productivity should be expected, and the time for obtaining useful information will decrease by more than ten times.
