Soil enzyme activities during the 2011 Texas record drought/heat wave and implications to biogeochemical cycling and organic matter dynamics

Enzymatic activity, microbial biomass, and organic carbon of Entisols from Brazilian tropical dry forest and annual and perennial crops

“…Specific activity per unit of MBC shows that enzymatic activity was produced by microorganisms because enzyme activity could be produced by animals, plants, and microorganisms (Acosta-Martínez et al, 2014). This specific activity is an important indicator that provides ecological information (Lagomarsino et al, 2011) and has been used in recent studies.…”

“…To determine the specific enzyme activity per unit of SOC, each absolute enzyme activity was divided by SOC (Acosta-Martínez et al, 2014). To determine the specific enzyme activity per unit of MBC, the enzymatic activity was divided by MBC according to previous methods (Medeiros et al, 2015).…”

“…Biochemical attributes are used extensively in the literature to assess quality in different land uses compared to forest (Raiesi and Beheshti, 2014;Acosta-Martínez et al, 2014;Medeiros et al, 2015). Yé et al (2017) studied soil chemical and biological characteristics of a perennially and annually grazed Sudanian savanna and showed that perennial grasses have a greater influence on soil attributes than annuals.…”

Dynamic characteristics of soil properties in a Robinia pseudoacacia vegetation and coastal eco-restoration

“…With the increase of soil moisture, enzyme potential activities increase (Baldrian et al, 2013;ÁBear et al, 2014). Whereas, Acosta-Martinez et al (2011) reported high enzyme activities in drought soil. This can be explained with the report that under waterlogging condition, enzyme activities were impeded (Kang and Freeman, 1999).…”

Socio-Economic Implications of Drought in the Agricultural Sector and the State Economy

“…For instance, Venkataramana et al [12] projected multi-year droughts in the late 21st century to occur across the state, with the worst droughts anticipated in El Paso. Effects of severe drought conditions on dissolved organic matter and ecosystems have been estimated by Miller and Shank [13], Acosta-Martinez et al [14], Lebreton et al [15], and Schwantes et al [16]. Specifically, the 2011 drought has accounted for considerable losses in agricultural production of $7.62 billion in Texas (not including timber production) [1,2,17].…”
