Abstract
Intisari Indonesia memiliki lebih dari 30 juta hektar lahan rawa, dengan sekitar 20,1 juta hektar berupa lahan pasang surut. Namun, hanya 5,27 juta hektar yang dimanfaatkan untuk pertanian, sementara 13,3 juta hektar lainnya berpotensi dikembangkan. Di Provinsi Jambi, khususnya Desa Pemusiran, lahan pasang surut yang digunakan untuk pertanian masih terbatas, dengan kendala utama berupa tingkat salinitas tinggi, kemasaman tanah, serta rendahnya ketersediaan unsur hara makro seperti nitrogen (N), fosfor (P), dan kalium (K). Tujuan dari penelitian ini untuk mengevaluasi status hara tanah sawah pasang surut di Desa Pemusiran, Kecamatan Nipah Panjang, Kabupaten Tanjung Jabung Timur, serta memberikan rekomendasi pemupukan guna meningkatkan hasil produksi padi. Pengambilan sampel berdasarkan Satuan Lahan Homogen (SLH). Sebanyak 16 sampel tanah diambil pada kedalaman 0-30 cm, kemudian dianalisis di Laboratorium Research and Development (R&D) PT. Nusa Pusaka Kencana. Hasil analisis menunjukkan bahwa status hara makro primer di lahan penelitian relatif rendah. N-total tanah berkisar dari rendah hingga sedang, P-total sangat rendah hingga sedang, sedangkan K-total tergolong sangat tinggi. Kandungan K yang tinggi diduga akibat kebiasaan petani mengembalikan sisa jerami ke lahan, sementara rendahnya P disebabkan oleh tingkat kemasaman tanah yang tinggi. Oleh karena itu, diperlukan strategi pemupukan yang tepat untuk meningkatkan kesuburan tanah dan produktivitas pertanian di lahan pasang surut ini. Kata kunci: lahan pasang surut, status hara tanah, pemupukan, kesuburan tanah, produksi padi. Abstract Indonesia has over 30 million hectares of wetlands, with approximately 20.1 million hectares classified as tidal wetlands. However, only 5.27 million hectares are utilized for agriculture, while the remaining 13.3 million hectares have the potential for development. In Jambi Province, particularly in Pemusiran Village, tidal wetlands used for agriculture remain limited, with major constraints including high salinity levels, soil acidity, and low availability of essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K). The objective of this study is to evaluate the nutrient status of tidal rice field soils in Pemusiran Village, Nipah Panjang Sub-district, Tanjung Jabung Timur Regency, and to provide fertilizer recommendations to enhance rice production. Soil sampling was based on Homogeneous Land Units (HLU). A total of 16 soil samples were collected at a depth of 0–30 cm and analyzed at the Research and Development (R&D) Laboratory of PT. Nusa Pusaka Kencana. The analysis results indicated that the primary macronutrient status in the study area was relatively low. The total N content ranged from low to moderate, total P was very low to moderate, while total K was categorized as very high. The high K content is suspected to be due to the farmers' practice of returning rice straw residues to the soil, while the low P content is attributed to the high soil acidity. Therefore, an appropriate fertilization strategy is needed to improve soil fertility and agricultural productivity in these tidal wetlands. Keyword: tidal wetlands, soil nutrient status, fertilization, soil fertility, rice production.
