Influence of long-term fertilization on soil enzyme activities

The soil under coffee, recent reforestation and secondary forest showed higher concentrations of organic carbon, but microbial biomass and enzyme activities were higher in soils

of 0-20, 20-40, and 40-60 cm, we determined the following soil properties: soil density, total porosity, macroporosity, microporosity, organic matter, clay dispersed

The highest root concentration, root length density (RLD), and root density (RD) were observed in the superficial layers of soil (0-20 cm), and under the dripline (30 and 70 cm

linear correlation between soil moisture determined in the field, at depths of 10, 20, 30, 40, 60 and 100 cm and the water storage in 0-100 cm depth, and the topographic and

The characters analysed included effect of pH (4 - 10) and temperature (30 - 80 o C) on enzyme activity and stability, effect of NaCl (0 - 20%) on enzyme activity, effect of

The soil tillage systems and groundcover crops influenced the soil enzyme activities both under the tree canopy and in the inter-row space.. humidicola provided higher amylase,

Ratio of soil enzyme activities to microbial biomass carbon (MBC) at the 0-20 depth, as affected by application of pig slurry doses under different soil tillage systems.. All

Number of subsamples per sampling point required to obtain soil penetration resistance (SPR) values with maximum errors of 10, 20 and 30% around the mean, for different soil layers
