Rice Yield Mystery Solved? Key clues revealed about declines in Asia On GlobalSpec

A high-tech look into how nitrogen interacts with organic matter and decomposing crop residues in submerged soils may have confirmed the cause of a potentially serious problem facing Asia's rice farmers. Growers of lowland rice ( ) have described significant declines in yield after several years of intensive cropping. Opinions vary, but researchers have eyed a decrease in availability of soil organic nitrogen—a key crop nutrient—as a cause. Annual cultivation of two or three rice crops

SAW Filters

SAW filters are electronic filters that are designed and manufactured using surface acoustic wave (SAW) technology. SAW uses piezoelectric transducers that, when excited, produce waves that are used to filter frequencies.

Video Cameras

Video cameras record live-action scenes that are available for viewing via a stored or transmitted video feed. This allows the user to create a permanent and detailed chronicle of events. Video cameras record dozens of pictures (or frames) a second that when viewed in succession, clearly distinguish the translation of an object or person over time.
