Effectiveness of Dicyandiamide (DCD) in Suppressing Nitrification in Tropical Soils: Relevance of Soil Type, Fertilizer Type and Soil Temperature

Dandeniya W.S., Konara K.M.B.M. & Hansika K.D. · Asian Journal of Soil Science and Plant Nutrition · 2025

Rapid nitrification under warm humid climate in the tropics leads to high nitrogen losses from soil. Understanding the factors deciding the performance of dicyandiamide (DCD) as a nitrification inhibitor (NI) is important for its applications in tropical agriculture. This study i...

Evaluating the Impact of Integrated Nutrient Management Practices on Land Productivity, Crop Residue Decomposition and Abundance of Soil Organisms in a Banana Plantation in Sri Lanka

Premarathne H.P.S.R., Dandeniya W.S. & Haputhantri T.R. · Asian Journal of Soil Science and Plant Nutrition · 2024

The fertilization practices heavily influence the decomposition rate of organic materials added to soil. Hence, the nutrient management strategies that aim to improve crop yields may not necessarily support organic carbon accumulation in soil and overall soil fertility. This stud...

Suitability of Potential Nitrification Rate Determined by Shaken Slurry Method to Capture the Contingent Effect of Liming of Two Tropical Soils

Konara K.M.B.M & Dandeniya W.S. · Asian Journal of Soil Science and Plant Nutrition · 2024

Potential nitrification rate (PNR) provides maximum soil nitrification rate under optimal incubation conditions, but optimum conditions may vary for different nitrifier species. This study investigated whether the estimates from PNR and nitrifying potential (NP) assays reflect th...
