“…The microbial respiratory activities were higher in the sheep manure-enriched soils than control soil, indicating higher organic matter decomposition rates as already described by Moura et al (2015). The microbial respiration with the aim of evaluating the long-term harmful effects during the growth of Avena sativa in the control and sheepmanure-enriched soils with the aim of establishing the possible environmental impacts on soils, plants, animals and mesofauna during the organic fertilizations of different crops.…”

The aim of this study was to evaluate the effects of sheep manure in agricultural soils on the behavior of Folsomia candida and initial growth and development of Avena sativa. For this, an Oxisol was submitted to different doses of sheep manure and was subsequently evaluated for Folsomia candida survival and avoidance behavior through standardized ecotoxicological assays, the initial performance of oats by germination test and the soil basal respiration rate by respirometry methodology. There was an increase in the basal respiration rate of the soil by the application of sheep manure and this was consistent with the increase of the doses. The survival rate and avoidance behavior of springtails were not altered and there was no change in the initial performance of oats, indicating that this manure can be used for organic fertilization of soils with low soil pollutant potential.

“…However, when observing the results of the 2 nd sowing period, it is possible to note that the ORG treatment promoted greater BR, which triggered a greater BR/IBR ratio, stressing that microorganisms, due to lack of carbon, were stimulated by glucose addition, highlighting the resilience and its potential response under favorable conditions (BABUJIA et al, 2010). It can also be highlighted that the greater BR observed reflects the highest microbial biomass activity, which in the short term, might indicate greater nutrient release to the plants (MOURA et al, 2015). Furthermore, in Table 5, in the 2 nd sowing period, for the ORG treatment, higher qCO 2 was observed.…”

Recent research suggests that soybean yield could be doubled in Brazilian conditions, implying that the base fertilization is pivotal, as it might influence chemical and microbiological soil indicators and, hence, the crop grain yield. The current study had the goal of assessing alterations in the chemical and microbiological soil indicators, in the short term, as well as the soybean biometric and grain yield performance as a function of different fertilizers for base fertilization, in two sowing periods. An experiment comprised of two sowing periods was carried out in the 2019/2020 season on a dystrophic Red Latosol, in north Parana state. Five treatments were assessed, comprising: 1) control; 2) mineral fertilizer; 3) organomineral fertilizer; 4) mineral fertilizer mixed with granulated gypsum; and 5) slow release mineral fertilizer. A randomized block design with four replicates was adopted. The following variables were assessed: chemical and microbiological soil indicators; final stand; first pod insertion height; plant height; stem diameter; number of pods per plant; number of grains per plant; number of grains per pod; grain mass per plant; and one thousand grain mass and grain yield. There is no base fertilization effect on the chemical soil indicators in the short term, however, there is an effect on the microbiological soil indicators. Soybean biometric and grain yield performance is decreased with the delayed sowing period, regardless of the type of fertilizer utilized for base fertilization. Analyzing a set of soil quality indicators enables precise and judicious results to be gathered on management practices in the soil environment.

“…Q-CO2 remained practically stable throughout the collection periods; however, a significant effect of the interaction was observed (Table 2). The different types of residues in the soil, in different amounts, alters the behavior of the microbiota, being able to stimulate or inhibit its activity, mainly in relation to the processes of transformation of organic matter and the cycling of nutrients and the exchange interactions with most of the plant species, especially those of agricultural importance (Moura et al, 2015).…”

The objective of this study was to evaluate the microbiological attributes of a Cohesive Yellow Latosol. Collections were carried out in three land use systems (LUS). The first, with natural rainforest (NR), the second with sugarcane (SC) cultivated since 2009, and the third under Mimosa cesalpiniifolia (MC) introduced in 1999. Microbiological analyzes were carried out by determining the carbon from microbial biomass, readily mineralizable carbon, microbial respiration, metabolic quotient, total organic carbon, microbial C/total organic C ratio, and occurrence of cellulolytic and ammonifiers microorganisms. Analysis of variance was performed to verify the different measures of microbiological attributes. The variation obtained from CMB was from 3.06 to 4 µg.C.g-1 in NR, 3.02 to 3.92 µg.C.g-1 in MC, and 3.14 to 3.24 µg.C.g-1 in SC. For accumulated CO2, no differences were found between environments, with values ranging from 77 to 55.70 µg.Kg-1 for NR, 80.30 to 49.56 for MC, and 80.30 to 49.56 for SC. qCO2 had no significant effect, and in relation to total organic carbon the forest soil (NR). These results demonstrate that the microbiological attributes of the soil are influenced by cover, environmental standards and soil management, and the sampling time. The forest soil showed superior microbial biomass when compared to other soils. The metabolic control detected a difference between the collection times. For the accumulated CO2 resources, no changes were observed.
