摘要:This paper briefly reviews certain aspects of man's response on exposure to a hot climate. The value of applying the concepts of thermal exchange analysis to evaluate the severity of a particular heat stress situation is emphasised. The possible effects of the Rome climate on a m...

摘要:Numerous experiments have been conducted in Maryland and Pennsylvania since 1981 to determine if adding the nitrification inhibitor dicyandiamide (DCD) to an ammonium-containing or producing N fertilizer source would increase the efficiency of that source with turfgrass, wheat, o...

摘要:The exchangeable soil Mg level recommended for agronomic crop production by different soil testing services ranges from 25 to over 180 ppm (?10% saturation of the cation exchange capacity). In some cases the justification for high soil Mg recommendations is to ensure that forage ...

摘要:Two new double-buffer methods have been proposed recently by Yuan and McLean, et al. to more accurately predict the lime requirement (L.R.) in sandy, low buffer capacity soils and in low L.R. soils respectively. The L.R. of 20 typical acid agricultural soils in Pennsylvania were ...

摘要:A total of seventy-three U.S. corn (Zea mays L.) inbreds and hybrids were grown in the greenhouse for two to four weeks in low and high available P nutrient solutions and soils to select for phosphorus efficiency based on yield differences in a low available P medium. Variation i...

摘要:Although it has been shown that the nitrogen (N) concentration of winter wheat (Triticum aestivum L. em Thell) at Feeke's growth stage 5 (GS 5) can be used to assist in making more accurate spring N fertilizer recommendations, the need remains to find a more convenient and accura...

摘要:The effects of a hot environment on physical work have been studied in 10 subjocts, divided into two groups of eight. Both groups performed work daily for four hours in cool conditions for two weeks, and thon on one day in a hot environment, Thoroufter, both groups continued...

摘要:A soil nitrate test taken about 4 weeks after emergence has been proposed to predict the corn (Zea mays L.) yield reponse to sidedress N fertilizer applications. Use of this test would be increased if the soil analysis and interpretation could be done rapidly, since the fertilize...
