Evapotranspiration Estimation Using Soil Water Balance, Weather and Crop Data
The rise in water demand for agriculture, industry, domestic, and environmental needs requires sagacious use of this limited resource. Since agriculture (mainly irrigation) is the major user of water, improving agricultural water management is essential. Efficient agricultural water management requires reliable estimation of crop water requirement (evapotranspiration). Evapotranspiration (ET) i...
متن کاملDiurnal Method for Evapotranspiration Estimation from Soil Moisture Profile
Water use of plants can be manifested in diurnal signal of soil moisture changes, and also of water table fluctuations in shallow water table environments. The signal can be especially strong in case of groundwater dependent forest vegetation with high water demand, where the water uptake is partly happening across the capillary zone. A new technique for water uptake estimation was elaborated o...
متن کاملImpact of Soil Moisture on Crop Yields over Brazilian Semiarid
The objective of this work was to investigate the relationship between soil water content and rainfall with rice, beans, cassava and corn yields in the semiarid region of Northeast Brazil. Precipitation and modeled soil water content were compared to yields recorded at the county levels in this region. The results were also integrated over the area of the nine States that lie within the officia...
متن کاملeffect of soil texture and bulk density on evapotranspiration and crop coefficient of forage maize
determination of crops water requirement in different environmental conditions is essential for preparation of precise and suitable irrigation scheduling. the effect of soil compaction and texture on crop coefficient and evapotranspiration of maize was investigated in this study, which was conducted as a factorial experiment with a completely randomized design in a research farm in jey and qaha...
متن کاملObserved timescales of evapotranspiration response to soil moisture
[1] The sensitivity of evapotranspiration (ET) to soil moisture storage plays an important role in the landatmosphere system. Yet little is known about its magnitude, or its dependence on vegetation, soil, and/or climate characteristics. Here we relate the sensitivity to the timescale of ET decay in absence of rainfall, and show that it can thus be derived from time series of ET alone. We analy...
