Phylogenetic surveys of soil ecosystems have shown that the number of prokaryotic species found in a single sample exceeds that of known cultured prokaryotes. Soil metagenomics, which comprises ...

By breaking the linkage between humin and inorganic soil colloids using inorganic (e.g., HF, H 2 SO 4, and Na 2 S 2 O 3) and organic (e .g ... Zhang J, Dou S, Song X. Effect of long-term combined ...

In this study, forced vibration analysis of a non-uniform energy pile in vertically inhomogeneous soil is presented considering non-uniform distributed temperature. In establishing the numerical model ...

Enzyme activities. Urease activity varied from 78 to 258 μg g-1 h-1 N-NH 4 in the soil under the tree canopy and from 63 to 154 μg g-1 h-1 N-NH 4 in-between rows (Table 2).Cultivation of L.

Tasmanian dairy farmers trial microbes across 500 hectares of land with the help of a "top-notch" soil biologist to reduce their reliance on synthetic fertilisers such as urea.

Accurate information on the chemical nature of soil phosphorus is essential for understanding its bioavailability and fate in wetland ecosystems. Solution phosphorus-31 nuclear magnetic resonance (31P ...

One greenhouse pot experiment was used to investigate the availability of phosphorus in struvite derived from urine affected by soil pH (cinnamon soil, pH 7.3; paddy soil, pH 5.3) and irrigation water ...
