Use of Tensiometers in Measuring Availability of Water to Plants.
Efforts by several investigators to measure availability of water to plants by vapor pressure (2, 12) and other methods (10, 14) have indicated that the potential of water at the permanent wilting percentage is approximately 16 x 106 ergs per gram, whereas others (1, 11) have obtained results which indicate somewhat lower values. A great many experiments (3, 4, 5, 6, 13) have demonstrated that ...
متن کاملPermanent Wilting Percentages of Soils Obtained from Field and Laboratory Trials.
In experimental work on the soil-water relations of plants in the field, it is advantageous to have some knowledge of the water-holding characteristics of the soil before the field trials are started. If the moisture equivalents or the field capacities and the permanent wilting percentages are known, an irrigation program for the various plots can be laid out in advance, with assurance that the...
متن کاملPolarimetric Soil Moisture Retrieval at Short Wavelength
Soil moisture was assessed with quad-polarimetric TerraSAR-X and dual-polarimetric (HH/VV) TanDEM-X data from the agricultural region of Wallerfing, Germany. The investigations included a bare soil case in April 2009 (TerraSAR-X) and a time series of 04-07/2011 (TanDEM-X) to estimate soil moisture on bare and vegetated soils including different agricultural crop types at various phenological st...
متن کاملAdsorption of arsenic on soil under different soil moisture conditions
The adsorption study was conducted on three Japanese soils with different soil properties to characterize the adsorption pattern of Arsenic (As). Double tube method was used to find out the effect of soil moisture levels on As adsorption. For this study, besides double tube method, conventional batch method also was used. The As adsorption showed two phase kinetics. An initial and rapid adsorpt...
