Iron (Fe) toxicity is one of the major constraints in lowland paddy soils in Southern Sri Lanka. The toxicity
is associated with reduced soil condition of flooded soils, which increases concentration of iron (Fe2+). Iron ...
Plant growth promoting traits which include indoleacetic acid (IAA), ammonia, siderophore and
hydrogen cyanide (HCN) production were assessed in two phosphate solubilizing bacterial (PSB)
isolates (Pantoea agglomerans ...

Ammonium nitrogen (NH4+-N) content in soil is a key factor affecting nitrous oxide (N2O) emissions due to its role as a primary substrate of nitrification. This study aimed at investigating the effects of different application ...
Oil palm (Elaeis guineensis) cultivation in Sri Lanka began several decades ago in the Galle district. Oil palm
cultivation expanded to the other regions of the Low country wet zone to reach the national edible oil ...
