Abstract Fixed NH 4+(NH 4+ f) and fixation and defixation of NH 4+ in soils have been the
subject of a number of investigations with conflicting results. The results vary because of …

This paper reviews the use of charcoal and wood ash in acid soils as adsorbents to improve
N availability at the same time improving their soil fertility and crop productivity. Soil …

Abstract The ammonium sulphate ((NH 4) 2 SO 4) in-situ leaching process is the most widely
used extraction technology for weathered crust elution-deposited rare earth ores (WCED …

Impacts of biochar addition on nitrous oxide (N 2 O) and carbon dioxide (CO 2) emissions
from paddy soils are not well documented. Here, we have hypothesized that N 2 O …

Urea is an important source of ammonia (NH3) emissions to the atmosphere from
agricultural soils. Abatement strategies are necessary in order to achieve NH3 emission …

Irrigation management has an important influence on emissions of nitrous oxide (N2O) and
nitric oxide (NO) from irrigated agricultural soils. In order to develop strategies to reduce the …

Weathered crust elution-deposited rare earth ore (WCE-DREO) are rich in middle and heavy
rare earth, and ammonium sulfate ((NH 4) 2 SO 4) was often used as leaching agent to …

The 15N isotope pool dilution (IPD) technique is the only available method for measuring
gross ammonium (NH4+) production and consumption rates. Rapid consumption of the …

Soil nitrogen (N) retention capacity can influence crop production, soil health, and
environmental quality, especially in greenhouse agroecosystem with multiple cropping and …

The water extract of compost termed “compost tea” retains all the beneficial soluble bioactive
components, making it a potent source of plant stimulatory and defensive compounds. The …
