dc.description.abstractTanah Ultisol yang mendominasi wilayah Sumatra Utara memiliki karakteristik masam dan miskin hara, sehingga memerlukan intervensi tambahan untuk mendukung budidaya tanaman, termasuk tanaman karet (Hevea brasiliensis). Salah satu pendekatan yang potensial adalah pemanfaatan mikroorganisme tanah sebagai pupuk hayati, terutama bakteri penambat nitrogen dan pelarut fosfat. Studi literatur ini bertujuan untuk mengkaji populasi bakteri tanah pada zona rizosfer tanaman karet serta peran ekologisnya dalam meningkatkan kesuburan dan produktivitas tanaman. Data diperoleh dari 25 sumber ilmiah, termasuk jurnal nasional dan internasional, serta buku referensi yang diterbitkan antara tahun 2000 hingga 2024. Hasil kajian menunjukkan bahwa bakteri seperti Azotobacter, Azospirillum, Rhizobium, Bacillus, dan Pseudomonas mendominasi rizosfer karet dan memiliki kemampuan dalam fiksasi nitrogen, pelarutan fosfat, produksi hormon tumbuh, serta pengendalian hayati patogen. Keberhasilan implementasi pupuk hayati sangat ditentukan oleh kesesuaian mikroorganisme dengan kondisi agroekosistem lokal. Oleh karena itu, eksplorasi mikroba spesifik Sumatra Utara menjadi penting sebagai dasar pengembangan strategi pemupukan yang lebih efisien dan berkelanjutan. The Ultisol soil, which dominates the North Sumatra region, is characterized by sour and nutrient poverty, so it requires additional interventions to support crop cultivation, including rubber plants (Hevea brasiliensis). One potential approach is the use of soil microorganisms as biological fertilizers, especially nitrogen-anchoring bacteria and phosphate solvents. This literature review aims to examine the population of soil bacteria in the rhizosphere zone of rubber plants and their ecological role in increasing plant fertility and productivity. Data was obtained from 25 scientific sources, including national and international journals, as well as reference books published between 2000 and 2024. The results showed that bacteria such as Azotobacter, Azospirillum, Rhizobium, Bacillus, and Pseudomonas dominate the rubber rhizosphere and have the ability to regulate nitrogen fixation, phosphate dissolution, growth hormone production, and pathogen biological control. The success of the implementation of biofertilizers is largely determined by the suitability of microorganisms with the conditions of the local agroecosystem. Therefore, exploration of North Sumatra-specific microbes is important as the basis for the development of more efficient and sustainable fertilization strategies.en_US
