The fertilizer will offer vital nutrients to paddy crops cultivated by in excess of a million paddy farmers in the impending Yala cultivation time and beyond.
Apatite in Sri Lanka is mined from Eppawala (Eppawala Rock Phosphate or ERP). The finely ground product is employed to be a direct application fertilizer for tea, rubber and coconut. ERP can be an indiscriminate combination of much more soluble primary crystals and a significantly less soluble secondary phosphate matrix full of ferruginous and aluminous compounds with a median P2O5 written content of 30%. The main crystals can certainly be separated through the groundmass by mechanical separation to provide selectively mined Most important crystals (SERP) that has better P2O5 (35 to forty two%) and lower R2O3 contents (about one%) compared to matrix.

Application ERP at a amount of twenty five P2O5 kg/contains a break up application and 50 P2O5 kg/ha (both break up and solitary applications) confirmed a TSP in sustainable agriculture Sri Lanka similar plant peak and an increase in dry make any difference production increment in comparison to the control. Significantly larger common panicle lengths and grain yields ended up noticed in each TSP and ERP utilized therapies compared to the control in Yala 2015.Nevertheless, comparable increments had been noticed only in TSP utilized remedy and ERP applications in a amount of 25 P2O5 kg/ha as a split application and fifty P2O5 kg/ha in Maha2015/2016. Inconsistency of growth and yield performances of ERP treatment options indicated the importance of long lasting experiments to determine appropriate rates and methods of ERP TSP for tea plantations Sri Lanka application.
