“…An increase in soil temperature may lead to changes in bacterial protein profiles, kinetic parameters related to breathing, and the decomposition rate of organic matter in the soil (Jezierska-Tys and Frąc 2008;Wyszkowska et al, 2013). Both own research and literature (Papatheodorou et al, 2004) indicate that bacterial diversity is limited by low temperatures.…”

“…The soil temperature slightly changed the ecophysiological diversity of the studied groups of microorganisms. In turn, Papatheodorou et al (2004) claim that bacterial diversity is greater in soils at higher temperatures. An increase in soil temperature may lead to changes in bacterial protein profiles, kinetic parameters related to breathing, and the decomposition rate of organic matter in the soil (Jezierska-Tys and Frąc 2008;Wyszkowska et al, 2013).…”

“…Biochemical activity, as well as microbial activity, is modified by the changing temperature of the soil (Jefferies et al, 2010;Papatheodorou et al, 2004;Vorboyova et al, 1996). Own research indicates that it is not possible to assume a constant temperature, because a stable temperature does not exist in the environment.…”

The aim of the study was to determine the response of soil microorganisms and enzymes to the temperature of soil. The effect of the temperatures: 5, 10, 15, 20, and 25°C on the biological properties of soil was investigated under laboratory conditions. The study was performed using four different soils differing in their granulometric composition. It was found that 15°C was the optimal temperature for the development of microorganisms in soil. Typically, in the soil, the highest activity of dehydrogenases was observed at 10-15°C, catalase and acid phosphatase – at 15°C, alkaline phosphatase at 20°C, urease and β-glucosidase at 25°C. The highest colony development index for heterotrophic bacteria was recorded in soils incubated at 25°C, while for actinomycetes and fungi at 15°C. The incubation temperature of soil only slightly changed the ecophysiological variety of the investigated groups of microorganisms. Therefore, the observed climate changes might have a limited impact on the soil microbiological activity, because of the high ability of microorganisms to adopt. The response of soil microorganisms and enzymes was more dependent on the soil granulometric composition, organic carbon, and total nitrogen than on its temperature.

“…diversity index for the BG soil bacterial community in comparison with the DEF soil, and the difference in soil moisture content was suggested to be the primary cause (Doi and Sakurai, 2003). Contrary to this, bacterial communities in Greek grassland soils scored increased values of the Shannon diversity index as the dryness became intensive (Papatheodorou et al, 2004). Thus, the diversity measurement for soils in question must be done at the same time.…”

“…Thus, the addition of organic matter is one of the foundations to obtain a biological equilibrium in the soil, favoring the microfauna and, consequently, increasing the dominance of free-living nematodes (PAPATHEODOROU; ARGYROPOULOU; STAMOU, 2004;BERRY;SPAULL, 2005).…”

Sugarcane plays an important socio-economic role in northeastern Brazil. However, the low yield in this region is associated with several factors (e.g. frequent occurrence of plant-parasitic nematodes). In order to observe the influence of soil organic matter on the nematodes, this study aimed to characterize the spatial nematode distribution in a sugarcane field. The study was carried out in Goiana -Pernambuco State (Brazil), fifty days after sugarcane cutting (10 days after vinasse application). The sampling scheme consisted of a regular 60 × 50-m grid, 10 m spaced, through 0 to 0.2 m depth. Spatial distribution was evaluated by semivariograms fit and performed by ordinary kriging interpolation for mapping. Exponential and spherical models promoted the best fit to semivariograms, resulting in ranges from 16 to 19 m. There was a strong negative correlation between soil organic matter and plantparasitic nematode population density. Free-living nematodes had a similar distribution pattern as soil organic matter content. These results indicated that soil organic matter had important effects on spatial distribution of both plant-parasitic and free-living nematodes. Key words: Soil microfauna. Semivariogram. Spatial variability. Vinasse. ResumoA cana-de-açúcar desempenha importante papel socioeconômico para o Nordeste Brasileiro. Por outro lado, a baixa produtividade nesta região está associada a diversos fatores, dentre estes, a relevante presença de nematoides fitoparasitas. A fim de verificar a influência da matéria orgânica sobre os nematoides, o objetivo deste estudo foi caracterizar a distribuição espacial da matéria orgânica e da nematofauna em área cultivada com cana-de-açúcar fertirrigada com vinhaça. O estudo foi realizado no município de Goiana, Zona da Mata Norte de Pernambuco, 50 dias após corte da cana (10 dias após aplicação da vinhaça). Utilizou-se um sistema de amostragem em malha regular de 60 × 50 m, com espaçamento de 10 m, na profundidade de 0-0,2 m. A distribuição espacial foi avaliada por meio de ajustes de semivariogramas e realizada interpolação por krigagem ordinária para mapeamento. O modelo esférico e o exponencial proporcionaram melhor ajuste aos semivariogramas, com alcances de 16 a 19 m. A matéria orgânica correlacionou-se negativamente com a população dos nematoides fitoparasitas. O mapeamento permitiu observar padrões de distribuição espacial similares entre as comunidades de nematoides de vida livre e a matéria orgânica. Esses resultados indicam que a matéria orgânica tem um papel importante na distribuição espacial dos nematoides fitoparasitas e de vida livre. Palavras-chave: Microfauna do solo. Semivariograma. Variabilidade espacial. Vinhaça.
