Stable isotope techniques can be used to investigate evapotranspiration and its partitioning into evaporation transpiration. However, verification is often difficult due missing information about actual evapotranspiration. Therefore, in this study a methodology tested for laboratory conditions was modified field applications. Evapotranspiration, which determined by weighing lysimeters, were com...

This study aimed to assess the accuracy of SIMULAT, a computer model primarily designed for predicting the fate of pesticides in soil. The evaluation was carried out by comparing simulated results on herbicide degradation with results obtained from ®eld and lysimeters experiments. For model validation four different data sets were available. The data sets included ®eld, lysimeter, and laborator...

A brief history of development of the 1985 Hargreaves equation and its comparison to evapotranspiration ~ET! predicted by the Food and Agricultural Organization of the United Nations ~FAO! Penman-Monteith method are described to provide background and information helpful in selecting an appropriate reference ET equation under various data situations. Early efforts in irrigation water requiremen...

Crop model intercomparison studies have mostly focused on the assessment of predictive capabilities for crop development using weather and basic soil data from same location. Still challenging is performance when considering complex interrelations between dynamics under a changing climate. The objective this study was to test agronomic environmental flux-related set models. aim predict weighing...
