The effect of different combinations of vermicompost and coir dust on microbial
respiration and nitrogen mineralization in soil was studied under laboratory
conditions. Treatment with 75% vermicompost and 25% coir dust ...

Identification of nitrous oxide (N2O) and carbon dioxide (CO2) emissions from soils amended with different types of compost is needed for appropriate use of manure in agriculture. This study aimed at investigating the ...
Liyanage, T.D.P.; Maeda, M.; Somura, H.; Mori, M.; Fujiwara, T.(Taylor & Francis, 2022-06-15)
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 ...

Purpose : Combine use of phosphate solubilizing microorganisms and organic manure has greater
agronomic utility as it could improve phosphorous (P) utilization efficiency through conversion of insoluble
P to accessible ...
Walpola, Buddhi Charana; Arunakumara, K.K.I.U.; Yoon, Min Ho(Chungnam National University, Korea, 2022)
Phosphorous (P) is considered to be one of the key essential elements demanded by crop
plants. Approximately 70 - 90% of phosphatic fertilizers applied to crops are fixed in soil as
Ca, Fe, and Al metal cations, which ...
