Temperature is an important factor regulating microbial activity and shaping the soil microbial community. Little is known, however, on how temperature affects the most important groups of the soil microorganisms, the bacteria and the fungi, in situ. We have therefore measured the instantaneous total activity (respiration rate), bacterial activity (growth rate as thymidine incorporation rate) a...

Different methods to estimate electrical conductivity (EC) of saturated soil paste extract (ECe) 1:2 and 1:5 soil: water suspensions were evaluated. Soil samples taken from different depths (viz. 0-15, 15-30, 30-45, 45-60, 60-90 cm) the wheat field under irrigated saline regimes ranging 1.5 12 dSm-1. The relationship between soil-water suspension extracts (i.e., EC1:2 EC1:5) was established bes...

Soils submitted to the same management system in places with little variation of landscape, manifest differentiated spatial variability of their attributes and crop yield. The aim of this work was to investigate the correlation between spatial variability of the soil attributes and sugarcane yield as a result of soil topography. To achieve this objective, a test area of 42 ha located at the São...

The percentage compositions of soil herbivorous, bacterivorous and fungivorous nematodes in forests, grasslands and scrubs in Romania was analysed. Percentages of nematode abundance, biomass and metabolic footprint methods were used to evaluate the patterns and relative size of herbivory, bacterial- and fungal-mediated channels in organic and mineral soil horizons. Patterns and magnitudes of he...

Post mortem changes are important in estimating post mortem interval (PMI). This project's aim was to study the effect of burial and type of clothing on rate of decomposition, which can contribute to estimating PMI for victims. 12 rabbits (Oryctolagus cuniculus) carcasses were separated into 3 groups: no clothing, light clothing and heavy clothing. Control subjects were placed on the ground sur...

This study aims to determine the characterization of alluvial soil as a place grow Chinese betel (peperomia pellucida L.) in Ambon city. Parameters studied included morphological and description nut (Peperomia pellucid L.). The results observations field analysis samples laboratory that have been collected are used material identify characterization. Meanwhile from was selectively explored by e...

During a rainfall water infiltration into an unsaturated soil, zones of saturation may be developed anywhere within the flow domain. Consequently, a natural question arises: under which conditions depending on the rate at which rain water is supplied, the initial moisture distribution in the soil, the presence of underground sources and the boundary permeability, the flow domain may be separate...
