Modeling soil evaporation and the response of the crop coefficient to leaf area index in mature Populus tomentosa plantations growing under different soil water availabilities

In order to improve water management in Populus tomentosa plantations, the variation in the FAO-56 parameters of the basal crop coefficient (Kcb) and soil evaporation (Es) in mature P. tomentosa plantations under different soil water availability treatments were investigated over two growing seasons. Empirical models for predicting Es in well-watered drip irrigated stands were constructed and validated. Changes in the relationship between Kcb...
