_Treating the wastewater with high level of urea and ammonia-nitrogen is one of the problems faced by urea fertilizer plants in Indonesia. The alternative treatment being studied is the one which uses Fenton oxidation process which is continued with the use of Pseudomonas fluorescens bacteria. This study is conducted with the concentration of ammonia-nitrogen of 2500 ppm, 2000 ppm, and 1500 ppm...

in order to understand the effects of different organic and chemical fertilizer on stigma yield, corm characterstics and leaf dry matter yield (as a forage) of saffron (crocus sativus l.), an experiment was conducted in the research station of faculty of agriculture, ferdowsi university of mashhad, iran, in 2005-2009; as a randomized complete block design with 12 treatments and three replicatio...

Abstract Urea, an agricultural fertilizer, nourishes humanity. The century‐old Bosch–Meiser process provides the world's urea. It is multi‐step, consumes enormous amounts of non‐renewable energy, and has a large CO 2 footprint. Thus, developing eco‐friendly synthesis for urea priority. Herein we report single‐step Pd/LTA‐3A catalyzed from NH 3 under ambient conditions powered solely by solar en...

background & aim: nowadays, tendency to agricultural biotic product sustainable agriculture instead of chemical ‎fertilizers has been going up in all over the world. so, most pharmaceutical industries prefer to ‎use raw material which is produced from organic and stable system. producing organic ‎medicinal plants, such as peppermint, seems important in economical, ecological and ‎bio enviro...

Abstract In this study, an eco-friendly controlled release fertilizer cellulose-based hydrogel was prepared from cellulose fibers derived wastepaper, epichlorohydrin (ECH) as a crosslinker and carboxy methyl (CMC) gelling agent. A maximum swelling capacity of 2000% achieved for with optimum composition. The soil moisture contents in the presence optimized hydrogels were determined using digital...

BACKGROUND The aim of this study was to evaluate the effects of nitroxin biofertilizer and chemical fertilizer on the growth, yield, and essential oil composition of dill. The experiment was conducted under field condition in randomized complete block design with three replications and two factors. RESULTS The first factor was the concentrations of nitroxin biofertilizer (0%, 50%, and 100%) o...

Recent human population increase has been enabled by a massive expansion of global agricultural production. A key component of this "Green Revolution" has been application of inorganic fertilizers to produce and maintain high crop yields. However, the long-term sustainability of these practices is unclear given the eutrophying effects of fertilizer runoff as well as the reliance of fertilizer p...
