The use of biochar has received growing attention because of its ability to improve the physicochemical properties of highly weathered Ultisols and Oxisols, yet very little research has focused on its effects in Aridisols. We investigated the effect of low or high temperature (250 or 500°C) pyrolyzed switchgrass () biochar on two Aridisols. In a pot study, biochar was added at 2% w/w to a Declo...
Abstract In terrestrial settings, the Permo-Triassic mass extinction is commonly linked to major changes in sedimentological and climatic conditions that include a switch from meandering braided fluvial systems increased aridity. We examined predominantly strata of North China reveal that, on contrary, there was little substantial change during extinction. The crisis level occurs upper Sunjiago...
Fodder yield and quality must be improved for sustainable livestock production. A lack of or low application phosphorus (P) potassium are among the leading constraints lower fodder sorghum [most cultivated crop during kharif season (crop cultivation in summer harvesting winter] Aridisol Pakistan. Therefore, this two-year field study evaluated role different P K levels on cultivar ‘Ijar-2002’ pl...
Biochar is one of the important recycling methods in sustainable development, as it ensures transformation agricultural wastes into fertilizers and conditioners that improve soil properties fertility. In current study, corn cob-derived biochar (CB) was used to reduce negative effects saline water on quinoa (Chenopodium cv. Utosaya Q37) grown Aridisols Entisols, which are major groups Egyptian s...
The North East area of El Baharya Oases represents one the highest priority areas for future agricultural development in Egypt. study is located between longitudes 29° 9' 28.354" , 27' 38.264" and latitudes 28° 47' 26.562" 3' 17.531" covers an about 101294 feddans. A physiographic map was produced to present mapping units area. classified into two landscapes, i.e., plateau 23.77 % total plain w...
the kinetics of zn sorption by ten calcareous soils of iran were measured and fitted to several equations (zero-, first-, second-, third-order, parabolic diffusion, simple elovich, and exponential equations). two initial concentrations of zinc i.e. 20 and 80 mg zn l-1 were used and observations were carried out for 100 hours. the time required to reach the near equilibrium state was about 24 ho...
Herbicide degradation is one of the key processes determining whether use herbicide will have any impact on environmental quality, and it dependent various biotic abiotic factors. The present study evaluates factors such as soil type, application rate, incubation temperature, pH, microorganisms sunlight persistence metribuzin its effect enzymes. Half-lives (DT50) varied significantly with rate ...
