Effects of Liming on Soil Properties and Its Roles in Increasing the Productivity and Profitability of the Oil Palm Industry in Malaysia

As global demand for edible oil increases, palm oil-producing countries in Southeast Asia are experiencing a rapid expansion of agricultural land industrial cultivation by converting existing lands and some tropical rainforests; however, soil acidity nutrient depletion two major constraints the tropics. Several factors may cause acidification, including natural processes, pollutants extensive production. Soil increases leaching many essential plant elements availability toxic modifying various geochemical biological reactions soil. Even though acidic is less fertile, productivity among highest world once chemical removed applying sufficient quantity lime fertilizers. Lime widely used alkali to improve fertility retaining nutrients, increasing biota, decreasing heavy-metal potentially achieving resistance against Ganoderma disease at estates. Liming materials not simple compounds with consistent properties; thus, selecting appropriate must be based on type price compared products neutralizing value, composition, fineness. Since primary aim liming pH, numerous reviews have been reported impacts deficiencies toxicity; no review has published that discusses effects growth yield. It enough emphasize just alone, thorough assessment also given crops (oil palm) biodiversity. This synthesizes current understanding introduces holistic approach provide insights into far-reaching biogeochemical properties crops.
