|Fertilizer Macro||N -First year 125 tons /year/ ha. Second-year, 250 tons/year/ha and 370 tons/ha/year after the third year
P- First year 180 tons /year/ ha. Second-year, 360 tons/year/ha and 520 tons/ha/year after the third year
K- First year 90 tons /year/ ha. Second-year, 190 tons/year/ha and 280 tons/ha/year after the third year
|Fertilizer micronutrients||Magnesium and Boron are critical for Oil palm growth.
Magnesium applies at a rate of 15, 30 and 45 tons/ha/year from 1st, 2nd and 3rd year onward.
Boron 5, 10 and 20 tons/ha/year from 1st, 2nd and 3rd year onward.
Kc = Crop co-efficient.
ETo = Reference evapo-transpiration (mm)
ETm = Maximum evapo-transpiration = Kc x ETo (mm)
ETa = Evapo-transpiration actual (mm)
Ya = Actual yield
Ym = Maximum yield
