“…Within this critical range, the soil performs its specific functions in natural ecosystems. As reported by Benintende et al [19], Stone et al [20] and Mbuthia et al [21], biological variables can be used as soil quality and health indicators. Soil respiration and enzymatic activities, particularly hydrolase activities, involved in organic matter turnover, hence in nutrient cycles and plant nutrition, are used by soil scientists to investigate the effects of different soil management strategies and agricultural practices including organic amendments on the soil quality and health [22][23][24].…”

“…The state of soil environment can be monitored using selected indicators. De la Rosa and Sobral [18] claimed that critical limits of soil quality indicators are threshold values, which must be adhered to for the normal functioning of the soil system [19]. Within this critical range, the soil performs its specific functions in natural ecosystems.…”

Response of Microbial Activities in Soil to Various Organic and Mineral Amendments as an Indicator of Soil Quality

et al. 2019

The presented paper deals with the analysis of potential differences between organic waste compost (CBD), vermicompost (CVER) and mineral fertilizer (MF; 27% of N) applications affecting the quality of arable soil by influencing microbial activity therein. The selected types of compost represent alternatives to conventional organic fertilizers, which are, however, not available to Czech and Slovak farmers in sufficient amounts. Their mutual comparison and the comparison with organic fertilizers aim to provide farmers further information about their influence on arable land and thus to give them the possibility of deciding on the most suitable amendments. To demonstrate the effect of these amendments, six variants were prepared: one without the addition of fertilizers; two variants with the addition of 40 Mg/ha of CVER and CBD; one variant with the addition of double dosed CVER (80 Mg/ha), and the remaining two variants were fertilized only with MF (0.22 Mg/ha) and with the combination of CVER (0.20 Mg/ha) and MF (0.11 Mg/ha). Substrate induced respiration (SIR), basal respiration (BS), microbial carbon (Cmic) and enzymatic activities (hydrolysis of fluorescein diacetate—FDA, dehydrogenase activity—DHA, and phosphatase activity—PA) were used to evaluate the effect of CBD, CVER and MF application on the soil quality. Both organic and mineral amendments affected BS and SIR. The highest BS and SIR rates were found in variants with compost application (CVER and CBD). All variants treated with the mineral fertilizer showed the lowest level of enzyme activities; lower by about 30% in comparison with variants where CVER, CBD and the combination of MF and CVER were applied. We found insignificant differences between the individual types of compost. More importantly, we compared the situation at the beginning of the experiment and after its end. It was found that the application of mineral fertilizers automatically led to the deterioration of all enzymatic parameters, on average by more than 25%, as compared with the situation at the beginning of the experiment. However, when the mineral fertilizer dose was supplemented with organic amendments (CVER), this negative effect was eliminated or significantly reduced. Furthermore, both composts (CVER and CBD) positively affected plant biomass production, which reached a level of production enhanced by the MF. Results clearly showed that the application of both compost types could be used to improve soil quality in agriculture.

“…This was an expected outcome, and agrees with previous studies on this issue (Anriquez et al 2005;Paz-Ferreiro et al, 2013;Benintende et al, 2015). Soil moisture is known to have a strong effect on soil microbiological activity (Lavelle et al, 2006).…”

1The processes involved in the flows of matter and energy of terrestrial ecosystems depends 2 heavily on soil biological activity, the current conventional agricultural managements could alter 3 the biological mechanisms involved in decomposition and nutrient cycling in agroecosystems. 4The aim of this study was to compare the activity levels and soil microbial biomass between 5 different agricultural pampean soil uses and its relationship to carbon mineralization. 25 years of 6 agricultural use were compared with 25 years of ecological reserve naturalized where each 7 agroecosystem soil were collected at 61 -125 -183 -236 -302 -368 -431 -488 days for 8 measuring their moisture, organic matter, enzymatic activity, microbial biomass carbon, soil 9 respiration, metabolic quotient, microbial quotient and carbon mineralization rate. The distance 10 between agroecosystems is less than 800 m, thus assuming the same soil and climatic conditions. 11The data were evaluated by Friedman test finding significant differences in moisture, organic 12 matter, enzymatic activity, soil respiration y microbial quotient (p< 0.01). Difference was also 13 found in the microbial mineralization rate of carbon (p< 0.1). 14 KEY WORDS 15Microbiological activity; carbon mineralization; soil use. 16PeerJ PrePrints | https://doi.org/10.7287/peerj.preprints.1608v1 | CC-BY 4.0 Open Access |

“…Most of these selected properties are also used as quality criteria in the CASH and SMAF. Several other researchers reported that lime, Ca, TN, and NO 3 -N that are not used in these assessment systems could be used as quality indicators (Baridón and Casas, 2014;Benintende et al, 2015;Liu et al, 2014;Mojiri et al, 2011;Sánchez-Navarro et al, 2015;Shirani et al, 2015;Viana et al, 2014;Zdruli et al, 2014).…”
