“…Seasonal changes in soil enzyme activity were also noted in other study areas. For example, soil phosphatase and β-glucosidase was higher in spring [54]; whereas peak invertase activity occurred in autumn [55]. The four soil enzymes we evaluated had peak activity in the summer when trees are actively growing.…”

Changes in forest stand structure may alter the activity of invertase, urease, catalase and phenol oxidase after thinning Pinus tabuliformis (Carriére) plantations in Yanqing County of Beijing, China. We examined changes in these soil enzymes as influenced by time since thinning (24, 32, and 40 years since thinning) for 3 seasons (spring, summer and autumn) following harvesting at two depths in the mineral soil (0-10 cm and 10-20 cm). Invertase and urease increased significantly with time since thinning. Catalase activity was highest in the 24-year-old stand and there were no statistically significant differences between the 32-and 40-year-old stands. In addition, maximum invertase, urease, catalase, and phenol oxidase activities occurred during the summer; minimum activities occurred in autumn. Invertase and urease were positively correlated with each other, as were catalase and phenol oxidase. Most soil enzyme activity was higher in the 0-10 cm layer than at the 10-20 cm depth. As time from thinning increased, differences among soil depth became less significant. These results suggest that seasonal changes of these enzymes have different roles, as the time since thinning and thinning treatments may have both short-and long-term impacts on soil microbial activity.

“…For instance, flow paths in coastal solonchak soils were observed to switch from runoff to leaching as a result of biochar addition due to the changes in the density of the soil structure (Kotroczó et al, 2014). Bailey et al, (2011) reported that some enzymatic activities increased after 7 d of biochar application to soil, which may be attributed to stimulation of microbial activity by the biochar.…”

“…Other organic amendment benefits are soil stability and buffering capacity (Ling et al, 2016), increase in soil carbon stocks (Xie et al, 2014) and improvement in soil structure and water retention (Yu et al, 2012), soil enzyme activities (Bowles et al, 2014;Kotroczo et al, 2014), and that they simultaneously provides maintenance of soil health (Chaparro et al, 2012) and suppression of soil-borne diseases (Qiu et al, 2012) Diverse types of long-term fertilization management at the study site exert significantly different effects on soil physical and chemical properties (Xun et al, 2016). In the long run organic farming system emerges as a sustainable adaptive agricultural practice that is less dependent on external high inputs and maintains the productive agro ecosystem that will meet our food and nutritional requirements.…”
