Evaluating spatial and temporal variations in sub-field level crop water demands
Frontiers in Agronomy, 2022 Variable rate irrigation (VRI) requires accurate knowledge of crop water demands at the sub-field level. Existing VRI practices commonly use one or more variables like soil electrical conductivity, historical yields, and topographic maps to delineate ...

Predicting soil moisture conditions for arable free draining soils in Ireland under spring cereal crop production [PDF]
, 2010 peer-reviewedTemporal prediction of soil moisture and evapotranspiration has a crucial role in agricultural and environmental management. A lack of Irish models for predicting evapotranspiration and soil moisture conditions for arable soils still ...

New Approaches to Irrigation Scheduling of Vegetables
Horticulturae, 2017 Using evapotranspiration (ET) data for scheduling irrigations on vegetable farms is challenging due to imprecise crop coefficients, time consuming computations, and the need to simultaneously manage many fields.

Estimation of crop water requirements: extending the one-step approach to dual crop coefficients [PDF]
Hydrology and Earth System Sciences, 2015 Crop water requirements are commonly estimated with the FAO-56 methodology based upon a two-step approach: first a reference evapotranspiration (ET0) is calculated from weather variables with the Penman–Monteith equation, then ET0 is multiplied by a ...
