“…Meskipun demikian, upaya ini biasanya belum dilakukan secara optimal dan berkesinambungan sehingga C-organik tanah di perkebunan kelapa sawit terus mengalami penurunan seiring pertambahan umur tanaman seperti dilaporkan oleh (Guillaume et al 2016). Laju penurunan C-organik yang tidak terkendali dan berlangsung terusmenerus dapat berakibat pada penurunan daya dukung tanah terhadap tanaman (Goh et al 2017;Widiastuti et al 2018).…”

C-organik tanah pada perkebunan kelapa sawit dapat dijadikan salah satu parameter keberlanjutan ekosistem dan kesuburan tanah. Perubahan sifat kimia tanah yang dinamis tidak lepas dari proses biogeokimia dari mineralisasi dan pelapukan bahan organik menjadi C-organik tanah. Penelitian ini bertujuan untuk mengkaji status C-organik tanah serta kaitannya dengan sifat kimia tanah lainnya dalam kurun waktu 5 tahun dari tahun 2009 sampai tahun 2014 di perkebunan kelapa sawit Sumatera Utara, dengan jenis tanah Inceptisols dan Ultisols. Metode pengambilan sampel menggunakan purposive random sampling. Data dianalisis menggunakan uji komparatif T-paired antara kebun yang diamati pada tahun 2009 dan 2014 untuk melihat perubahan nilai C-organik, dan parameter sifat kimia tanah. Uji korelasi dilakukan untuk melihat keterkaitan antara C-organik dengan parameter sifat kimia tanah lainnya, yaitu kadar N, kejenuhan Al, pH, dan kapasitas tukar kation (KTK). Hasil penelitian menunjukkan bahwa dari 25 kebun pengamatan, nilai C-organik dari 3 kebun meningkat dan 6 kebun menurun secara signifikan, sedangkan 16 lainnya tidak berbeda nyata. Dalam periode 5 tahun, kandungan Corganik tanah cenderung fluktuatif namun tetap berada pada kelas yang sama dengan kisaran rendah hingga sedang (<1,75%). Peningkatan nilai C-organik hanya berkorelasi linier dan nyata dengan N pada tanah Inceptisols (r = 0,392). Sedangkan, pada tanah Ultisols, peningkatan Corganik tanah secara nyata diikuti dengan penurunan nilai pH (r =-0,141).

“…Demikian juga dengan total populasi jamur dan bakteri yang ada pada setiap blok, baik pada kedalaman 0 -15 maupun 50 -60 cm, cenderung tidak berkorelasi dengan intensitas serangan Ganoderma. Hasil ini relatif sama dengan hasil penelitian Widiastuti et al, (2018) di mana korelasi antara total bakteri dengan Ganoderma sp. paling umum meskipun sangat rendah.…”

The relationship of biological properties of peat with oil palm basal stem rot (BSR) caused by Ganoderma. Indonesia as the largest palm oil producer in the world, has the large percentage of oil palm on peatland. The serious problems of cultivating oil palm on peatland is the presence of BSR disease caused by Ganoderma. There are no effective methods to control the spread of this disease. Biological control is an environmentally friendly alternative method focus, but on peatland, the development of this method is constrained by lack of information about the effect of biological environmental factors. This study aims to determine the effect of the biological propertiess of peat on the intensity of Ganoderma attacks on oil palm. The relationship between the intensity of Ganoderma attacks and biological properties of peat was carried out by correlation test. The correlation analysis showed that the biological properties of peat has not correlated with the Ganoderma attacks, except Summed Dominant Ratio of vegetation which tends to positively correlate to the number of Ganoderma antagonists. These results indicate that peatland vegetation management by maintaining the diversity of vegetation around oil palm can help reduce Ganoderma attacks.

“…At the global level, palm oil crops are dealing with numerous pressures [ 4 ], like pathogens represented by fungi, bacteria, viroids, and viruses [ 5 ], which are affecting the oil palm by reducing yield or retarding growth [ 6 ]. At various times, oil palm plantations from southeast Asia, Africa, and South America were affected by almost 32 diseases and disorders [ 7 ].…”

The oil palm Elaeis guineensis represents one of the most important crops in Ecuador. Considering that bud rot disease is deadly in Ecuador, more attention has been given to identifying possible causes for palm debility from this disease. We studied the involvement of fungi and nutrients in triggering bud rot disease in E. guineensis. Special emphasis was given to the molecules synthesized by the plant to protect against this devastating disease. Techniques like Diagnosis and Recommendation Integrated System (DRIS) and metagenomic analysis were used to understand the possible implications of biotic and abiotic factors in the development of bud rot disease in oil palm in Ecuador. Liquid chromatography-mass spectrometry (LC-MS) analysis was used to identify the phenolic protection barrier of the palm facing the disease. Our results indicate that fungi from Ascomyceta phylum were found in the tested samples. The species directly involved are different in soil compared with plants. The results indicate a deficiency of chemical elements, such as Ca, Mn, Mg, and Fe, which are responsible for palm debility from bud rot disease. More than 30 compounds with protective roles were identified in the leaves of symptomatic plants from the first stage of the infection.
