the effects of land use, crop type and crop management on soil fauna were investigated with survey of four habitats in jajarm. the habitats included rangelands, alfalfa (medicago sativa l.) fields and low-input and high-input of wheat (triticum aestivum l.) fields, each with four sample units. in each sample unit, the macrofauna collected with pitfall traps, sorted and counted in terms of famil...

abstract information about the spatial patterns of soil biodiversity is limited though required, e.g. for understanding effects of biodiversity on ecosystem processes. this study was conducted to determine whether soil macrofauna biodiversity parameters display spatial patterns in the riparian forest landscape of karkhe. soil macrofauna were sampled using 200 sampling point along parallel trans...

abstract soil invertebrate and their spatial pattern are affected strongly by environmental factors. spatial variability of soil properties is one of the most important reasons of the macrofauna variability. this study was conducted to investigate the spatial variability of soil properties and soil macrofauna biomass in the riparian forest landscape of karkhe river. soil macro fauna were sample...

Soil is the most basic resource for sustainable agricultural production; it promotes water quality, is a key component of the biogeochemical cycles and hosts a huge diversity of organisms. However, we are not paying enough attention to soil degradation produced by land use. Modern agriculture has been successful in increasing yields but has also caused extensive environmental damage, particular...

Microbiological activity is a general term which includes all metabolic reactions and interactions of the soil microflora and macrofauna.1 Soil microorganisms contribute to soil fertility and aggregate formation in degraded soils.2 However, it is only during the last decades that ecologists have beginning to explore the underground communities and their functional significance for the plant com...

This work presents a survey of the macrofauna and chemical fertility soil in two sample areas same valley; it verifies if type vegetation cover positively impacts on greater diversity quantity edaphic macrofauna; as consequence increase macrofauna, there is correlation between population fertility. The comparison made areas: area 01, occupied with Brachiaria brizantha integrated native cerrado ...

Although soil invertebrates play a decisive role in maintaining ecosystem functioning, little is known about their structural composition in Alpine soils and how their abundances are affected by the currently ongoing land-use changes. In this study, we re-assessed the soil macrofauna community structure of managed and abandoned Alpine pastureland, which has already been evaluated 14 years earli...
