Erosion process: |
Runoff
and soil loss. |
|
8.2
Location (town, state, country): |
China,
Indonesia, Laos, Malaysia, Philippines, Thailand and Vietnam. |

LABORATORY EXPERIMENTS Description of the laboratory
and the type of experiments and equipment involved for each
of the erosion processes studied: |
|
All
the cooperators have their own laboratory to analyze both physical
and chemical properties of the soils collected from the experimental
plots, including erosion samples. The analyses include N, P,
K, OM, pH, CEC, Ca, Mg, aggregate stability, Db and mechanical
analysis. |
