“…It was also demonstrated in this study, that the abundance was found parallel with the available phosphorus concentrations in the soil. In connection with this finding Fekete et al (2011) found, that more organic P can enhance the alkaline phosphatase activities, which finally increase the Pavailability in the soil. The alkaline phosphatase is mainly produced by the soil microorganisms and the extent of its synthesis and excretion of it can be coupled to the microbial activity and/or the population size, as it was shown by Garg (2008) and Kaleeswari (2007).…”

Sugars, acids, and antioxidants as biologically active compounds, are significant elements of healthy tomato foods. The question arises if beneficial bioeffector microbes are able to improve the food quality of the tomato up scaled, among organic environmental conditions? Spore-forming bacteria used in the industry of Bacillus amyloliquefaciens FZB42 as single inoculums and its combinations with other Bacillus strains and N-fixing siderophore bacteria were used on tomato test plant in pots and in an organic field experiment. Soil nutrients, yield, and inside fruit quality, the content of some essential organic acids and sugars were measured during the growth period. The abundance of aerob heterotroph soil microbes was determined by the Most Probable Number method. A single industrial inoculum of used bioeffector had a positive effect on P-availability and yield in the pots. Among field conditions, the greater variability in environmental parameters could diminish the final significant differences of soluble P in soil and fruit yield. The soil available P-content and the fruit Total Soluble Solid content (TSS) and soluble sugar and organic acid content were significantly improved (p<0.05) both in pots and in the organic field conditions. Combination of different microbial treatments did not give further enhancement. There were seasonal differences also recorded in sugar-acid ratio, mainly at the field experiment. Appropriate bioeffector applications are the part of sustainable, organic and healthier tomato food production.

“…Likely, the low canopy coverage of this young stand (3000 trees/ha as compared to 5600 or 3770 in the older stands) was less, thereby resulting in greater understory vegetation and root production [70]. Higher numbers of fine roots in the upper mineral soil horizons may have also contributed to increased enzyme activity [71,72].…”

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.
