In a world of diminishing water reservoirs and a rising demand for food, the practice and development of water stress indicators and sensors are in rapid progress. The heat dissipation method, originally established by Granier, is herein applied and modified to enable sap flow measurements in date palm trees in the southern Arava desert of Israel. A long and tough sensor was constructed to with...

Meltwater discharge and electrical conductivity were measured in eight 1 3 1 m lysimeters, and snow accumulation and electrical conductivity of melted samples were measured in snow pits during four snowmelt seasons at Mammoth Mountain, California. The peak snow-water equivalent ranged from 0.57 to 2.92 m over the four melt seasons. Lysimeter discharges ranged from 20% to 205% of the mean flow; ...

Equilibrium-tension lysimeters were used to evaluate and compare dissolved reactive phosphorus (DRP) leaching from a prairie and fertilized no-tillage and chisel-plowed corn agroecosystems on Plano silt loam (fine-silty, mixed, superactive, mesic Typic Argiudolls) in south central Wisconsin during four monitoring periods, March through April 1996, 1997, and 1998, and from January 1999 through S...

The purpose of this investigation is to study the effect 1) leachate recirculation (LR) and dilution (LD), 2) increment waste ratio, 3) co-digestion using poultry as co-substrate for enhancing acidogenesis process organic municipal solid (OMSW), thereby increasing medium chain fatty acids (MCFAs) production. results experiment carried in a batch pilot reactor show that LR increases hydrolysis w...

Systematic and elaborate multidisciplinary research of pedunculate oak and common hornbeam began in the Forest Research Institute in Jastrebarsko in 1991. That led to a development of a method for monitoring deposition in forest ecosystems which is now closely related to the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forest. Several forest comm...
