Abstract:

As a contribution to an agroclimate study, a simple method was set up to estimate the available waterholding-capacity (AWC) of soils in Europe. Soil data taken from maps were stored on the basis of a 1/2 x 1/2 degree grid. For each grid cell three dominant soil types were recorded, with information on topsoil texture, stoniness and slope. The dataset covers the European territory up to the 44th degree of longitude. The method for estimating AWC is based on texture available reserve relations, given in the literature. For five texture classes mean values of available reserve (cm/cm soil) were summarized in a conversion table. The crop rooting depth determines the thickness of the soil layer contribution to the AWC. The rooting depth was derived from the soil type. A reduction factor was proposed for stony soils. For each grid cell a mean AWC figure can be determined by taking into account the relative proportions of the soil types concerned. An example was worked out for the cells covering The Netherlands.
