To approach the objectives of the
study, the experiment was designed in a
step-by-step fashion as seen in Figure 1.
Which chemical fertilizer with N:P:K
ratio (20:8:20), dried centrifuged residue,
dried swine dung are then mixed into 4
treatments as detailed more in TableThen, the values of 1) the growth
enhancement of Para rubber seedling, 2)
chemical properties of soil after blends
usage, and 3) chemical properties of water
leachate, of all 4 treatments are measured
and analyzed for the feasibility of the
studied blends
