Influence of soil properties on fluorescein diacetate hydrolyzing activity under different agro-ecosystems
TLDR
In this paper, the FDHA in both soil pretreatments showed positive correlation with organic matter (0.98∗∗ for field moist soil and 0.92∗ ∗ for air-dried soil) and clay content.Abstract:
Fluorescein diacetate hydrolyzing activity (FDHA) of soils, both in field moist and air dried, of different agro-ecosystems in alluvial soil was studied. Field moist soils recorded higher values than in air-dried soils, but they showed significant positive correlation (0.93∗∗). FDHA in both soil pretreatments showed positive correlation with organic matter (0.98∗∗ for field moist soil and 0.92∗∗ for air-dried soil) and clay content (0.85∗∗ for field moist soil and 0.82∗ for air-dried soil) of the soils. Multiple regression analysis showed that the stabilization of FDHA in the studied soils was due to organic matter-enzyme complex. Among the organic matter fractions, humus C plays dominating role to control the FDHA of the soils.read more

Influence of different forms of acidities on soil microbiological properties and enzyme activities at an acid mine drainage contaminated site
Prafulla Kumar Sahoo,Pradip Bhattacharyya,S. Tripathy,Sk. Md. Equeenuddin,Mruganka K. Panigrahi +4 more
TL;DR: Though acid mine drainage affected soils had higher microbial biomass and activities due to higher organic matter content than those of the baseline soils, the ratios of microbial parameters/organic carbon indicated suppression of microbial growth and activitiesdue to acidity stress.

Parthenium hysterophorus L. (Asteraceae) invasion had limited impact on major soil nutrients and enzyme activity: Is the null effect real or reflects data insensitivity?

TL;DR: Overall, there was a tendency for increased soil major nutrients and microbial traits with Parthenium weed invasion, and the magnitude and/or direction of the weed invasion is affected by complex interactions among environmental factors that might change across invaded habitats and survey periods, making broad generalizations un-informative for management.
