modifications. The reaction mixture consisted of 2 mL of sodium phosphate, pH 7.0, 0.5 mL H 2 O 2 (40 m m ), and 0.5 mL enzyme. The decomposition of H 2 O 2 was measured by the decrease in absorbance at 240 nm. The activity of CAT was expressed as U 240 , in
soil layers, respectively. Statistical analysis. Soil data were expressed on oven-dried soil basis. One-way analysis of variance (ANOVA) was performed to compare the results among the treatments using SPSS 16.0 software (SPSS Inc., Chicago, IL). Means
-through or batch treatment modes with varying hydraulic residence times ( Burgoon et al., 1995 ). Removal or transformation of nitrogen (N) and P occurs through microbial assimilation/transformation, decomposition, plant uptake, adsorption
). Inorganic or organic P, which has no valency changes during its biotic assimilation or microbial decomposition, is mainly removed through microbial and plant uptake ( Vymazal, 2007 ). Roots and rhizomes support rhizospheric microorganisms by providing
resources were identified. The DEA then, as is well-known, allows the decomposition of the overall inefficiency into genuine technical inefficiency or, in other words, into the incapacity of an enterprise to optimally combine the factors of production and to
rainfall frequently occurs in spring and fall, which can induce flooding, especially in areas with poorly drained soils ( Kijne, 2006 ). Flooding affects soils by altering soil structure, depleting O 2 , accumulating CO 2 , inducing anaerobic decomposition
Applications, 2018 ), and from an on-farm station in Monmouth, ME (HOBO U30; Onset Computer Corporation, Bourne, MA). Statistical analysis. Least-squares means were compared using analysis of variance (ANOVA) using R ( R Core Team, 2017 ) with tarp duration as
component in the media that is resistant to decomposition ( Bar-Tal et al., 2019 ; Bilderback et al., 2005 ). Peat and coir, on the other hand, decompose and settle over time, eventually reducing the volume of the media ( Bar-Tal et al., 2019
and SNK differences for main effects and interactions were calculated using the appropriate standard error term. For most of the variables measured, the full analysis of variance, involving first-order variables and interactions, was significant for
Analyzer; elementar Americas, Inc., Mt. Laurel, NJ), whereas P and K were determined with an inductively coupled argon plasma atomic emission spectrophotometer. Statistical analysis. Two-way analyses of variance (α = 0.05) and mean-separation with Tukey
