Experimentally induced root mortality increased nitrous oxide emission from tropical forest soils [PDF]

open access: yes, 2003
We conducted an experiment on sand and clay tropical forest soils to test the short‐term effect of root mortality on the soil‐atmosphere flux of nitrous oxide, nitric oxide, methane, and carbon dioxide.

Ameliorating effects of palm oil mill effluent on the chemical properties of soils and maize growth in pots [PDF]

open access: yes, 1995
Highly weathered Malaysian soils are mostly acidic having high Al saturation and low Ca and/or l\1g contents. A leaching experiment in PVC columns and a pot trial were carried out to alleviate these acid soil infertilities by application of palm oil ...

Mass Proportion of Microaggregates and Bulk Density in a Brazilian Clayey Oxisol.

open access: yes, 2005
The physical properties of Brazilian Oxisols are closely related to the development of their microstructure, which typically consists of stable microaggregates smaller than 1 mm. There is no model available to predict changes in microstructure in Oxisols.

Effect of ground basalt on chemical properties of an ultisol and oxisol in Malaysia [PDF]

open access: yes, 2010
Highly weathered soils in Malaysia need to be amended to rejuvenate their chemical fertility. In particular, soil pH should be increased sufficiently, while exchangeable Al eliminated in order to make them productive.
