What role do soil and vegetation play in the spatial variability of non-rainfall water inputs in agroecosystems under water-limited conditions?
What role do soil and vegetation play in the spatial variability of non-rainfall water inputs in agroecosystems under water-limited conditions?
Non-rainfall water inputs from dew, hoar frost, rime, fog, or soil water vapor adsorption are often neglected as water inputs to the ecosystem. Such sources are particularly important to maintenance of ecosystem services and for the survival of the flora and fauna in the ecosystem under water-limite...

Non-rainfall water inputs from dew, hoar frost, rime, fog, or soil water vapor adsorption are often neglected as water inputs to the ecosystem. Such sources are particularly important to maintenance of ecosystem services and for the survival of the flora and fauna in the ecosystem under water-limited conditions.The determination of the different non-rainfall water input fractions for different soils and land cover forms under similar climatic conditions has not been investigated. We present a conceptual measurement setup that allows us to determine each non-rainfall water component for natural and extensive grasslands as well as for agricultural ecosystems. Using this conceptual system, we will compare the temporal development and occurrence of different NRW components for eight different agroecosystems under the same climatic conditions and determine the influence of land cover form and soil on the formation of different non-rainfall water input fractions. |
