Herbaceous communities located within forest openings increase plant species diversity of forests in the Knobs Region of Kentucky. Although these grass-dominated communities are protected and managed for rare plant species conservation, it is unclear how soil conditions may delineate the grassland-forest ...
In the Horqin Sand Land, more than half of the original pasture area has been converted to farmland over the last century. A field experiment was conducted from 2000 to 2001 on five croplands in the Horqin Sand Land of Inner Mongolia to examine differences in soil properties, crop productivity...

Properties of nitrogen mineralization and nitrification of brown forest soil were examined in mature plantations of Japanese cedar and hinoki cypress in the southern part of the Shikoku district. Net nitrogen mineralization rate of the surface soil was 8.4 mg N kg-1d-1 and 2.7 mg N kg-1d-1 ...
Analysis of soil properties, the compositional traits in bulk soil and different fractions and their responses to afforestation practices may possibly facilitate clarification of the mechanisms underlying soil changes. Soil properties, the compositional functional groups and minerals were determined in the bu...
