Liming is often applied to alleviate soil acidification and increase crop yield on acidic soils,but its effect on soil phosphorus(P)availability is unclear,particularly in rice *** objective of this study was to examine the effect of liming on rice production,yield and P uptake in a three-year field experiment in a double rice cropping system in subtropical *** also conducted an incubation experiment to investigate the direct effect of liming on soil available P and phosphatase activities on paddy soils in the absence of *** the incubation experiment,liming reduced soil P availability(measured as Olsenextractable P)by 14–17%and inhibited the activity of soil acid ***,lime application increased grain yield,biomass,and P uptake in the *** increased grain yield and P uptake more strongly for late rice(26 and 21%,respectively)than for early rice(15 and 8%,respectively).Liming reduced the concentration of soil available P in the field as well,reflecting the increase in rice P uptake and the direct negative effect of liming on soil P *** together,these results suggest that by stimulating rice growth,liming can overcome direct negative effects on soil P availability and increase plant P uptake in this acidic paddy soil where P is not the limiting factor.

To assess safety and efficacy of propofol and thiopental for refractory status epilepticus (RSE) in children, the authors reviewed 34 episodes of RSE. Thiopental was effective in most patients, but there were serious side effects. Propofol was used according to a strict protocol. It was effective in most patients, so that thiopental was not needed. Side effects were infrequent, of minor severity, and fully reversible. The authors suggest the use of propofol before thiopental.
