Soils and Soil Solutions

1997
Soils are often extremely heterogeneous in their structure and chemical composition. A soil not only consists of solid matter of mineral or organic origin but also contains numerous pores, which altogether form a cavity system that is connected to the atmosphere.

SOIL EXTRACT IN SOIL MICROBIOLOGY

Canadian Journal of Microbiology, 1958
Soil extract contains unidentified growth factors not present in other materials. In this study the extract was considered critically in so far as various treatments affect numbers of bacteria developing on soil-extract agar. Dilution of the extract to 1/10th concentration produced lower counts in most soils.

Soil data for crop-soil models

1993
Systems approaches for agricultural development can be realized at different levels of detail which are associated with different data needs. For soils five levels were defined, ranging from farmer’s knowledge and expert systems to use of complex simulation models.

Soil genesis, soil classification and soil survey

Geoderma, 1970
Abstract Mutual relationships exist between soil genesis, soil classification and soil survey. The first two subjects are dealt with separately. Some of the general lines in soil genetic investigation are traced. Next trends in soil classification are dealt with.

Soil Biology: Soil Animals and Soil Acidity

1994
The role of soil animals is in general poorly known. Several studies have shown that soil fauna may accelerate the decomposition rate and contribute to the release of plant nutrients, but there is a need for more exact quantitative knowledge in this field (e.g., Anderson et al.

Soil Biology: Soil Microflora and Soil Acidity

1994
The low content of inorganic nutrients in forest soils makes the microbial activities in this ecosystem an important factor in regulating the amounts of available nutrients for the growth of trees. In such soils most of the fine roots of forest trees will be in an intimate symbiotic association with the mycelia of different fungi, thus greatly ...
