Methods of identification models of soil humidity

For the operational forecasting of the dynamics of moisture reserves, it is reduced to the prediction of precipitation and total evaporation (E). The remaining elements of the balance either do not change over time, are either known or are defined as functions of P and E. The plant’s need for water E (evapotranspiration) is determined on the basis of the bioclimatic method in the modification of B.V. Danilchenko (2) by the formula: Eu = Е К b K M (1
