Soil dehydrogenase activity in agro-ecological sub regions of black soil regions in India

Changes in the persistence of two phenylurea herbicides in two Mediterranean soils under irrigation with low- and high-quality water: A laboratory approach

“…Non-sterile soils behave similarly with a maximum at the beginning of the incubation and reaching a constant value thereafter, when soil enzymatic activity stabilises (Hernández-Soriano et al, 2009;Herrero-Hernández et al, 2011;Marín-Benito et al, 2012). The higher DHA values for S2 soil are probably due to higher nutrient availability and OC content (Table 1) (Yuan and Yue, 2012;Velmourougane et al, 2013). Furthermore, the higher DOC content of S2, less humified as evidenced by the lower HIX value (Table 1), also reflects a more available OC for soil microorganisms (Cox et al, 2000;Zaman et al, 2002).…”

Relationship between microbial functions and community structure following agricultural intensification in South American Chaco

“…It is widely known that DHA is susceptible to low pH (Velmourougane et al 2013), then in NV this enzymatic activity was probably performed by different microbial groups than those found in the agricultural treatments, which may explain the lower values obtained in NV compared to crop rotation treatments (R15 and R4).…”

Soil Quality Index Models for Assessing Walnut Orchards in Northern Erbil Province, Iraq

“…Soil enzymes are among the essential soil parameters related to the nutrient cycle in nature which reflects microbial activities in the soil [24,50] and acts as soil Table 3. Table 4.…”
