Oil palm (Elaes guineensis Jack) is an annual plantation crop that is widely cultivated by the community and large companies, oil palm plants produce fresh fruit bunches which are produced to produce Crude Palm Oil (CPO). This study aims to determine the nutrient content contained in oil palm plants and determine the productivity level of oil palm given various types of fertilizers. The research was conducted at the company PT. Perkebunan Nusantara XIII (Persero) Pelaihari and at the Laboratory of the Environmental Research Center, Lambung Mangkurat University, Banjarbaru. carried out in December 2019 to January 2020. This study uses a field survey method on oil palm fields of the same age, sampling is carried out by purposive sampling, namely sampling by determining special characteristics according to the research objectives. The nutrient content given by the three types of fertilizers, namely PK, LC, and TKKS was less effective because the balance of one nutrient with another had not been achieved. The nutrient content of the application of PK fertilizer, namely the element N is high (3.85%), P element is high (0.27%), K element is low (0.69%), Ca element is high (2.47%), Mg is high (0.85%), and Fe is low (0.21%). Nutrient content of the type of LC fertilizer, namely element N is classified as high (3.74%), element P is classified as high (0.29%), element K is classified as low (0.42%), element Ca is classified as optimum (0.71%), elemental Ca is classified as optimum (0.71%) Mg is low (0.08%), and Fe is low (0.14%). Nutrient content of the type of OPEFB fertilizer, namely element N is high (4 %), element P is high (0.29 %), element K is low (0.53%), element Ca is classified as high (7.87 %), element Mg is high ( 2.03%), and the element Fe is classified as low (0.20%). The productivity of oil palm plants given the three types of fertilizers (PK, LC, and TKKS) based on the potential for land suitability for S2 of 28 tons/ha/year is still low at 19.8 tons/ha/year (PK), 17.7 tons/ha /year (LC), and 17.3 tons/ha/year (TKKS) Keywords: oil palm, fertilizer content, nutrients, productivity
