Discerning shifting irrigation practices from passive microwave radiometry over Punjab and Haryana
Overexploitation of groundwater (GW) in the recent past is a well-known fact for the Punjab and Haryana region of India, as reported by several studies using satellite-based gravity anomaly from the Gravity Recovery and Climate Experiment mission and also by using observed data. This decline in GW has enforced the Punjab Preservation of Sub-Soil Water Act 2009, and resulted in change in rice ...

In-situ soil moisture conservation: utilisation and management of rainwater for crop production
The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally cultivated fields. ...

Total Suction of Artificial Mixtures of Soil Compacted at Optimum Water Content
The effect of soil composition on total suction is investigated. Thermocouple psychrometers are used to measure total suction of compacted specimens of artificial soil mixtures prepared using kaolinite, sodium montmorillonite, and a fine sand. Specimens are compacted in a Harvard miniature compaction mold at the optimum water content. The measured total suction is related to fine fraction and ...
