متن کاملGrowing Potatoes with Slow-release Nitrogen Fertilizer
Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

-brain levels of HCP varied between 0-442 and 1-204 nmol[g (0-18 and 0 49 ig/g).4 So myelinopathy in case 2 was probably attributable to HCP, despite the absence of clinical signs of toxicity. The trace level in case 1 suggests that myelinopathy was unrelated to HCP, for other causes of infantile spongioform myelinopathy are known, though none has been identified in small premature infants. Nev...
متن کاملSynthesis of merlinoite from Chinese coal fly ashes and its potential utilization as slow release K-fertilizer.
This study focuses on the synthesis of merlinoite from Chinese coal fly ashes by KOH direct conversion method, with special emphasis on the application of synthetic merlinoite as fertilizer. These fly ashes were collected from two pulverized-coal combustion (PCC) power plants in Xinjiang, Northwest China. The synthesis results are influenced by fly ash characteristics and different synthesis co...
