Review of the development of POME applications.

Methods	Dosage	Results	References
Randomly sampling on peat soil (soil analysis)	@700 g mixed with the liquid waste of palm oil	There was a change in composition for the pH value and mineral content of the peat soil after the application of POME with a pH value of 6.20, C-organic 2.38%, N-total 0.28%, phosphorus 63.34 ppm, Calcium 2.40 cmol/kg, magnesium 1.37 cmol kg−1, potassium 1.06 cmol kg−1, and CEC 9.47 cmol kg−1.	[67]
Biopore (palm oil mill effluent from an aerobic pool)	5; 7.5; and 10 liters of liquid waste of palm oil are provided in 1, 2, 3, and 4 biopore/plant holes, respectively	The application of POME dose of 7.5 liters in four biopores/plant holes increased the number of midribs and leaves, leaf width and length compared to the control and the highest form of other treatments.	[98]
Mulching with the size of 1.2 × 1.4 m with plant spacing 60,70 cm.	100, 200, and 300 ml per plan Mixed crops with palm ash	The interaction of POME and ash significantly affected plant height and weight of fruit/plant with the best dose of giving POME 300 ml with a fruit weight of 670 g per plant.	[99]
Mulching plot size 4 × 4 m with a spacing of 20 × 40 cm)	25000, 50000, 75000, 100000, and 150000 L/ha	Applying 150000 L ha−1 POME can replace dolomite lime, manure, urea fertilizer, and KCl in improving the chemical properties of ultisol soil for soybean production.	[97]
