Influence of hillslope on biological pools of carbon, nitrogen, and phosphorus in acidic alfisols of citrus orchard
This study assessed how different hill slope positions under uniform management practice within a Khasi mandarin orchard (Citrus reticulata Blanco) influence biological pools of carbon (C), nitrogen (N), and phosphorus (P), and soil quality
that hill slope position and soil moisture had significant influence on variability of soil biological pools. Sizes of biological pools were significantly higher in post-monsoon than post-winter. It is highlighted that hill slope position and soil moisture

Negative and positive effects of topsoil biological crusts on water availability along a rainfall gradient in a sandy arid area
of the prevailing idea regarding the positive relationship between average annual rainfall and ecosystem characteristics. The findings are attributed to the decisive role played by the non-uniform properties of the topsoil biological crusts along the rainfall

The reclamation activity of the opencast bauxite mines has two phases : technical and biological. During technical reclamation, land is transformed into a state comparable to the original conditions. Biological recultivation includes soil
This paper sketches out a method for a quantitative description of landscape structure, which can be used for biologically optimal landscape management. The approach suggested is based on a landscape ecological framework and emphasis is laid
on spatial characterisation of the landscape. It aims at supplementing conventional landscape descriptive parameters of biological importance, which are derived from a range of empirical data, with a spatial characterization. The method is implemented
surface community, and thus the style of biological weathering. A simple, preliminary conceptual model can be drawn, which relates biological weathering activity to an environmental stress gradient and which is applicable at a range of scales.

The measured values presented in the paper indicate that the soil biological activity must not be neglected even at soil temperatures below the freezing-point. At low temperatures, too, a marked dependency was found to exist between soil temperature
and CO exhalation which can be quantified with high statistical significance. Equally, the supply of plant substance markedly increases the biological activity. (HL).
