Changes in soil microbial biomasses and their quotients over the succession of karst rocky desertification [PDF]

open access: yesProceedings of the 3rd International Conference on Advances in Energy and Environmental Science 2015, 2015
To evaluate soil fertility of karst land undergoing rocky desertification (RD), the changing trend of soil microbial biomass properties over the succession of RD were studied by investigating the stands and analyzing the soil samples with four different RD grades in the northwestern Hunan province, China.

Microbiological indicators of tropical soils quality in ecosystems of the north-east area of Peru

open access: yesScientia Agropecuaria, 2019
Tropical soils withstand heavy pressure due to deforestation as a result of the change in land use, decreasing their quality. Traditionally, the quality of soil has been based on physical and chemical indicators; however, the biological ones can predict ...

Mechanism of endocarp-imposed constraints of germination of Lannea microcarpa seeds [PDF]

open access: yes, 2008
Lannea microcarpa, a multipurpose tree species from the dry African savanna, sheds seeds that often display inhibition of germination. The underlying mechanism was investigated using seeds processed from fully matured fruits collected from natural stands
