This study examined the efficiency of different organic waste materials as NPK fertilizer, in addition to the risk for leaching losses related to shower precipitation in the first part of the growing season. The experiment was tested in a pot trial on a sandy soil in a greenhouse. Six organic fertilizers were evaluated: liquid anaerobic digestate (LAD) sourced from separated household waste, ni...

Increasing food demand has resulted in an ever increasing for nitrogen fertilizers. Ammonium is the main constituent of these fertilizers and a threat to aquatic environments around world. With focus on treatment drinking water, scope this study was investigate influence key parameters suitability granular natural zeolites as adsorbents ammonium. Sorption experiments were performed artificial m...

Perchlorate, an iodide uptake inhibitor, is increasingly being detected in new places and new matrices. Perchlorate contamination has been attributed largelyto the manufacture and use of ammonium perchlorate (the oxidizer in solid fuel rockets) and/or the earlier use of Chilean nitrate as fertilizer (approximately 0.1% perchlorate). However, there are regions such as the southern high plains (T...

The aims of the study were to analyse the concentration of nitrate and ammonium ions in soil solutions obtained using MacroRhizon miniaturized composite suction cups under field conditions and to determine potential nitrogen leaching from soil fertilized with three types of fertilizers (standard urea, slow-release urea, and ammonium nitrate) at the doses of 90 and 180 kg ha-1, applied once or d...

abstractabout 30 to 50 percent of applied nitrogen fertilizers leached from soil to ground waters which can causes environment contamination and various human health problems. the rotation type can affect nitrogen mobility rate, so it is necessary to study effect of rotation type in on nitrogen movement. in order to evaluate effects of three main rotations in khuzestan province on inorganic for...
