Modelling soil water content variations under drought stress on soil column cropped with winter wheat

Winter Wheat Growth in Artificially Compacted Soil

Bound Water in Durum Wheat under Drought Stress.

To study drought stress effects on bound water, adsorption isotherms and pressure-volume curves were constructed for two durum wheat (Triticum durum Desf.) cultivars: Capeiti 8 (drought tolerant) and Creso (drought sensitive). Plants were grown under well-watered and water-stressed conditions in a controlled environment. Differential enthalpy (DeltaH) was calculated through van't Hoff analysis ...

Legume Green Fallow Effect on Soil Water Content at Wheat Planting and Wheat Yield

a system has been referred to as green fallow (Gardner et al., 1993). These systems have sometimes been sucGrowing a legume cover crop in place of fallow in a winter wheat cessful in the cooler regions of the northern Great Plains (Triticum aestivum L.)–fallow system can provide protection against (Zentner et al., 2001). Zentner et al. (2004) reported that erosion while adding N to the soil. Ho...

Preliminary Study on Soil Moisture Forecast of Winter Wheat

Using four groups of survey data of soil moisture of winter wheat from returning green stage to harvest stage in Daxing region, the variation laws of soil moisture exponential depletion relations in 0-60cm depths during different growth stage are analyzed ,and based on soil moisture exponential depletion relations the forecast model of soil moisture depletion is built. The results indicate that...

Water balance modelling of a cropped soil: deterministic and stochastic approaches

A capacity-based simulation model has been developed to predict components of the field water balance. The model requires daily information such as the atmospheric evaporative demand and rain events, maximum-available soil water storage (MAWS) and root growth characteristics as weil as crop and soil factors. Actual evapotranspiration is modelled using Eagleman's parameterization. The model was ...
