Carbon and Nitrogen Mineralization of a Plant Residue Amended Soil: The Effect of Salinity Stress

Walpola, B. C.; Arunakumara, K. K. I. U. (2011)

A factorial combination of saline and non-saline soil with three residue types (Sesbania grandiflora, Caliandra calothyrsus and Gliricidia maculata leaves) was used in laboratory incubation. The CO2-C content of plant ...
EFFECT OF PARTICLE SIZE OF GLIRICIDIA LEAVES AND SOIL TEXTURE ON N MINERALIZATION

Walpola, B. C.; Arunakumara, K. K. I. U. (Belihuloya, Sabaragamuwa University of Sri Lanka, 2009)

Decline in soil productivity and environmental quality in the tropics have led to a search for new methods to sustain crop production via more efficient nutrient cycling. In tropical agricultural systems with limited ...
EFFECT OF SALT STRESS ON DECOMPOSITION OF ORGANIC MATTER AND NITROGEN MINERALIZATION IN ANIMAL MANURE AMENDED SOILS

Walpola, B. C.; Arunakumara, K. K. I. U. (The Faculty of Agricultural Sciences of the Sabaragamuwa University of Sri Lanka, 2010)

As it is believed that soil salinity can alter the organic matter turnover process, the present study discussed the influence of soil salinity on the decomposition of organic matter and nitrogen mineralization in animal ...
