Calculation of moisture in various soil layers under corn crops according to the agrohydrometeorological dat
Journal Title: Agrology - Year 2019, Vol 2, Issue 3
Abstract
Agricultural crops during the growing season use moisture from various layers of soil. The root-bearing layer of corn varies from 10 cm in the period of sowing to 70‒80 cm in the period of ripeness. It raises the question of determining the soil moisture for every day of vegetation at any depth. It is proved that now the agrohydrometeorological method for determining the moisture reserves in the meter and half-meter soil layers yields good results. Therefore, in this work, the use of this method for calculating soil moisture throughout the soil profile with an interval of 10 cm is substantiated. The proposed model for the formation of moisture reserves yields good results both in natural moisture and in the case of irrigation. The use of this model for soil moisture formation according to seven meteorological stations in Dnipropetrovsk region is explored. As an example, the results of the meteorological station Gubinicha are presented. The results obtained in this way can be presented in the form of moisture content as a percentage of the mass of dry soil or as a fraction of the lowest moisture content in depth during the vegetation. The method allows the use of meteorological values, measured directly on the studied areas. This is especially true of rainfall and irrigation. The application of research results will help to more accurately determine the moisture reserves in the roots of the soil layer, to plan the optimal timing of sowing crops, to effectively carry out care activities, to target mineral fertilizers, and to maintain soil moisture in the required limits for irrigation.
