- Conservation agriculture and tillage effects on soil organic matter and residual moisture content in selected upland crop production systems in the PhilippinesElla, Victor B.; Reyes, Manuel R.; Padre, R.; Mercado, Agustin R. Jr. (2014)This presentation describes a study to analyze the influence of conservation agriculture and tillage on soil organic matter and residual moisture content in selected upland crop production systems in the Philippines
- Improving the water distribution uniformity of a low-cost drip irrigation system using adjustable pressure-loss lateral takeoff valvesElla, Victor B.; Keller, J.; Reyes, Manuel R.; Yoder, R. (2010)This presentation explains a study conducted at the University of the Philippines Los Baños which measured the effect of using Adjustable Pressure-Loss Lateral Takeoff Valves (APLTVs) on the water distribution uniformity of a low-cost drip irrigation system under sloping conditions. These researchers used many calculations and graphs to show that in general, the inclusion of APLTVs as a built-in component of the low-cost drip irrigation system can potentially increase crop productivity and yield.
- Influence of conservation agriculture and tillage on soil quality in selected crop production systems in the PhilippinesElla, Victor B.; Reyes, Manuel R.; Padre, R.; Mercado, Agustin R. Jr. (2014)The presentation describes a study to evaluate the influence of conservation agriculture and tillage on selected physical and chemical soil quality parameters in selected upland crop production systems in the Philippines
- Soil quality assessment under Conservation Agriculture Production Systems in the PhilippinesElla, Victor B.; Reyes, Manuel R.; Padre, R.; Mercado, Agustin R. Jr. (2014)This poster presents research on the impact of conservation agriculture practices on soil quality parameters in Claveria, the Philippines.
- Variability of selected physical and chemical soil quality parameters under conservation agriculture production systems in the PhilippinesElla, Victor B.; Reyes, Manuel R.; Padre, R.; Mercado, Agustin R. Jr. (2013)This presentation describes the results of tests on soil from fields under conservation agriculture production systems.
- Water distribution uniformity improvement of microtube-type and button-type drip irrigation system using adjustable pressure-loss lateral takeoff valvesElla, Victor B.; Keller, J.; Reyes, Manuel R.; Yoder, R. (Hokaido, Japan: International Commission of Agricultural and Biosystems Engineers (CIGR), 2012)Irrigation application using microtube-type and button-type drip irrigation systems tends to be relatively non-uniform especially under steep slopes and low operating heads. This study was conducted to determine the effect of using a device called Adjustable Pressure-Loss Lateral Takeoff Valves (APLTVs) on water distribution uniformity of both types of drip systems
