Implementing the dual crop coefficient approach in interactive software. 1. Background and computational strategy

Irrigation planning and scheduling require the availability of modeling tools that are accurate, quick and easy to use. The crop coefficient (Kc)-reference evapotranspiration (ET) method is a traditional method for estimating ET, but has become relatively complicated with the introduction of the dual Kc procedure. The dual crop coefficient approach (Kcb + Ke) gives a better estimation of daily crop evapotranspiration because it separately...
