gypsiferous soils occur in xeric, ustic, and aridic moisture regimes. environmental conditions affect the mode of gypsum formation. gypsiferous soils in fars province, southern iran, are found in piedmont plains, flood plains, and alluvial plains. the objective of this work was to investigate the micromorphology of gypsum crystals formed under different soil moisture regimes. the results indica...

The growth and yield of crops in the arid and semi-arid regions of the world is driven by the amount of soil moisture available to the crop through rainfall and irrigation. Various methods have been developed for quantifying the soil moisture status of agricultural crops. Recent technological advances in remote sensing have shown that soil moisture can be measured with a variety of remote sensi...

      Aridity as a spatial concept and drought as a temporal concept have always been studied in different aspects as two distinct categories. However, both concepts indicate anomalies from normal condition. Several indices have been introduced to examine each of these concepts using one or more hydrological cycle’s components. Meanwhile, soil moisture and changes in its spatial and temporal va...

Currently, remote sensing techniques provide the most feasible capability to monitor soil moisture over a range of space and time scales, such as passive microwave radiometric measurements in the 1-5 GHz range. It is found that variations in the brightness temperature are related most closely to the moisture content in a shallow near surface region, even if the actual sensing depth depends on t...

With black soil (Pachic Udic Argiboroll) of Northeastern China as the test object, an incubation test was conducted to investigate the effects of urease inhibitors, hydroquinone (HQ), phenyl phosphorodiamidate (PPD) and N-(n-Butyl) thiophosphoric triamide (NBPT), on the kinetic characteristics of soil urease under normal moisture and waterlogged conditions, aimed to study the changes of catalyt...

Capacitive methods for determining soil moisture are extremely practical and easily applied in the agriculturalenvironment, but influenced by temperature, salinity type of soil. In this study, aim was to verify performanceof Moisture Sensor Porous Media when subjected saline media. The sensor under evaluation wasdeveloped at Federal University Ceará, provides measurements electrical frequencies...
