through several mechanisms. Competition between weeds and cover crops will occur to varying degrees based on the vineyard environment and management. Allelopathic suppression of weeds has been observed upon decomposition of legume residues, such as clovers
new stems (2006 stems and leaves) and old stems (2005 and 2004 stems) were determined. All data were tested for homogeneity of variance using Levene's test and for normality using the Shapiro-Wilk W test. Biomass and composition data were analyzed
from each treatment replication at corresponding dates to represent the net mineralization of the amendment or amendment/crop combination. A repeated measures analysis of variance (Proc Mixed, SAS version 9.2; SAS Institute, Cary, NC) with an
Soil water content has an important impact on many fundamental biophysical processes. It affects the germination of seeds, plant growth and nutrition, microbial decomposition of the soil organic matter, nutrient transformations in the root zone, as
decomposition, the origin of the material, and the particle size or surface area ( Ahmad et al., 2001 ; Aslam et al., 2013 ; Benoit et al., 2008 ; Dao, 1991 ). There have been few studies focusing on sorption of preemergence herbicides used in ornamentals
measured using three methods: graph paper, image, and weight. The three mulch area measurement methods were then compared for accuracy, and the weight method was then used to compare treatments. Mixed model analysis of variance (version 9.4; SAS Institute
microbial immobilization, and wood substrate stability (decomposition) over time have been major concerns of researchers and growers ( Boyer et al., 2012 ; Jackson et al., 2008b , 2009). Wright and Browder (2005) demonstrated ‘Inca Gold’ marigold could be
the field prevented a third harvest for the study. Data were subjected to analysis of variance (ANOVA) with mean separation by least significant difference P ≤ 0.05 (SAS version 9.1; SAS Institute, Cary, NC). Expt. 2. Hurricane Wilma occurred on 24
firmness was measured using a penetrometer (Fruit Tester; Wagner Instruments, Greenwich, CT) with an 8-mm plunger. Statistical analyses. Analysis of variance was performed using the Proc Mixed procedure of SAS (version 9.2C for Windows; SAS Institute, Cary
. CEC of bark batches. Three samples from each of the four bark batches were collected for CEC analysis. Three separate samples were collected and measured for D b . Data were subjected to analysis of variance (ANOVA) and means were separated with Fisher
