“…It did follow the air temperature trend -when the air temperature dropped so did the maximum temperature in each treatment (Figure 2), unlike the results obtained by Nascimento et al (2016a), which showed that in the period from 10 to 18 days after transplanting the melon seedlings the treatment with vegetable cover + polyethylene mulch had the highest soil temperature. However, the same did not occur in the period from 30 to 46 days after the transplant, the soil temperature dropped during that treatment.…”

“…Polyethylene mulch can also capture volatile and nonvolatile substances, released from the soil and organic matter, that can potentially affect the soil microflora. However, practices to raise soil temperature need to be taken with caution as such high temperature can be detrimental to the beneficial soil microorganisms that are important for agriculture (NASCIMENTO et al, 2016a).…”

“…These microbes promote soil health and consequently plant growth by catalyzing unique and indispensable transformations in soil formation, soil biogenesis, organic matter decomposition, toxins degradation, and biogeochemical cycling (SHEN et al, 2018). The composition of the soil microbial community is influenced by several factors, such as temperature, moisture, soil aeration, organic substrates, and nutrient availability (NASCIMENTO et al, 2016a). These factors are likely to be affected when soilborne pathogen management strategies are performed.…”

Growers have adopted monoculture to maintain the high melon (Cucumis melo L.) production demand in the Northeastern region of Brazil. This cultivating practice culminates in up to three crop cycles per year being used in the same growing area. The main objective of this study was to evaluate if the incorporation of plant material used with polyethylene mulch and or in association with commercial soil amendment products can help to condition an environment that is beneficial to soil microbial communities. Two identical greenhouse experiments were conducted using a completely randomized design with seven treatments and seven replications. The treatments were: (C) – Control, (M) - polyethylene mulch, (C+M) - incorporation of Crotalaria juncea L. + polyethylene mulch, (P+M) - incorporation of Pennisetum glaucum L. + polyethylene mulch, (M+CS) - polyethylene mulch + (Compost-Aid® + Soil-Set®, trade names of products produced by Alltech Crop Science), (C+M+CS) - incorporation of C. juncea L. + polyethylene mulch + (Compost-Aid® + Soil-Set®), and (P+M+CS) - incorporation of P. glaucum L. + polyethylene mulch + (Compost-Aid® + Soil-Set®). To quantify the target soil microbiota (fungi, bacteria, sporulating bacteria, and actinomycetes), isolations were attempted on selective culture media specific for each group of microorganisms. The incorporation of P. glaucum together with the use of polyethylene mulch and commercial products (Compost-Aid® and Soil-Set®), (P+M+CS), increased the total fungal population by 183%, total bacteria by 55%, sporulating bacteria by 21%, and actinomycetes by 146% in relation to the control treatment.

“…The use of conservationist cultivation practices and maintaining residues influence the soil microclimate, the distribution and decomposition of crop residues, mineralization and immobilization of nutrients, besides the edaphic fauna structure in soil (CHENG et al, 2017;SILVA et al, 2018). These changes can alter the microbial activity and biomass of the soil, besides the structure of the microbial community in agricultural soils (NASCIMENTO et al, 2016). Thus, agricultural soil management practices may markedly affect microbial activity, the rate of organic matter rotation and, finally carbon and nitrogen cycling in soil (LI et al, 2018).…”

Carbon and nitrogen from the soil microbial biomass play a significant role in the rotation of C and N, and promote nutrient cycling. Thus, the objective of this study was to evaluate changes in the soil microbial biomass with growing doses of cover plant straw species. The cover plants cultivated in the cerrado biome region were incorporated an Oxisol Ustox. The straw of each cover plant was incorporated at doses of 0; 10; 20 and 30 Mg ha-1. The soil basal respiration was determined by incubating, after 21 days. The microbial biomass carbon and nitrogen were determined by the method the microwave irradiation. The microbial biomass carbon and nitrogen contents in extracts were determined by the wet combustion method and Kjeldahl-N. The metabolic quotient was calculated as the ratio between soil basal respiration rate and microbial biomass C, and the microbial quotient as the ratio between soil microbial biomass C and total carbon of soil. The soil microbial population measured by the attributes of quality responds to the addition of the of grass and legume straws incorporated to the soil; The treatments that cause the greatest stress to the microbial population, at 21 days, mediated by the metabolic quotient, are guandu-anão at a dose of 10 Mg ha-1; Guandu-anão and Guandu fava-larga at 20 Mg ha-1 and Brachiária at a dose of 30 Mg ha-1; The best result regarding microbial attributes of soil quality evaluated was observed with the incorporation of all doses of the straw of Crotalaria-ocroleuca.

Soils with appropriate water and air conditions improve microbiological activity, but agriculture frequently deteriorates soil’s physical requirements and impairs microbes’ survival. The main aim of this study was to evaluate the relationship between physical soil conditions and microbiological activity under different agricultural use and management systems in the warm tropical climate of Colombia. To evaluate physical soil conditions, bulk density (Bd), total porosity (Pt), macroporosity (MPt), water content, temperature, and mechanical penetration resistance (MPR) were measured on surface soil (0 to 10 cm) at three different use and management systems: irrigated rice (IR), pasture (P) and native forest with cacao (FC). The measured biological properties were the carbon of microbial biomass (C-MB) and the presence of bacteria and fungi. Soil organic carbon (SOC) was determined to calculate the microbiological quotient (MQ). The C-MB was significantly higher in FC (132.25) and P (148.11) but lower in IR (41.61). No significant differences were observed between the soil use system in the count of bacteria and fungi. The MQ (0.44) was higher in IR (0.22), revealing a significant effect of the soil use system on microbiological activity. Less anthropic intervention and permanent plant covers, such as FC and P, enhance microorganism’s survival, evidenced by higher C-MB content, correlated with soil Bd and MPt. The abundance of bacteria and fungi in the soil is affected by the physical conditions, primarily by Pt and MPt. However, fungi survive better with less water content, existing a differentiated effect of the physical conditions of the soil.
