| Judul Artikel | Studi Kandungan Unsur Hara Sulfur dan C-Organik Tanah Sawah untuk Rekomendasi Pemupukan Padi di WIlayah Sub DAS Serayu Hilir di Kecamatan Kesugihan, Kabupaten Cailacap |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui: (i) persebaran unsur hara Sulfur dan C-Organik di lahan sawah sub DAS serayu hilir Kecamatan Kesugihan, Cilacap, (ii) hubungan Sulfur dan C-Organik tanah dengan hasil tanaman padi sawah di sub DAS serayu hilir Kecamatan Kesugihan, Cilacap, dan (iii) rekomendasi pemberian pupuk organik untuk pertanaman di Kecamatan Kesugihan, Cilacap. Penelitian ini dilaksanakan pada Desember-Juli 2020 dengan metode survei pada tingkat ketelitian semi detail dengan skala 1:50.000. Penentuan titik sampel dilakukan berdasarkan Peta Satuan Lahan Homogen (SLH) yang dibuat dengan cara menumpang susunkan (overlay) peta yaitu Peta Administrasi, Peta Tata Guna Lahan, Peta Kemiringan Lereng dan Peta Jenis Tanah Kecamatan Kesugihan. Pengukuran sifat kimia tanah menggunakan metode yang biasa digunakan oleh Laboratorium Tanah Fakultas Pertanian Unsoed. Hasil analisis sifat kimia tanah di lahan sawah Kesugihan menunjukkan bahwa pH tanah rata-rata bersifat netral, daya hantar listrik sangat rendah, potensial redoks rata-rata termasuk pada kelas tereduksi sedang, kandungan C-organik sangat rendah (0,02-0,18 %), kandungan sulfur tersedia rata-rata tersedia rendah (21-46 ppm). Rekomendasi pemupukan untuk meningkatkan unsur hara sulfur di Kesugihan dengan pupuk ZA sebesar 63,68 kg ZA/ha. Rekomendasi pemupukan untuk meningkatkan C-Organik tanah di Kecamatan Kesugihan dengan pupuk kandang sebesar 7-8 Ton/ha. Kata Kunci : C-Organik, Sulfur, Rekomendasi Pemupukan, Padi. |
| Abtrak (Bhs. Inggris) | This study aims to: (i) determine the distribution of Sulfur and C-Organic nutrients in the rice fields, (ii) know the relationship between Sulfur and C-Organic soil with rice fields; and, (iii) find out recommendations for giving organic fertilizers for rice crop in the downstream Serayu sub-watershed Kesugihan District, Cilacap. This research was conducted in December-July 2020 with a survey method at a semi-detailed level of accuracy with a scale of 1:50,000. Determination of the sample point is based on the Homogeneous Land Unit Map (SLH) which is made by overlaying the map, namely the Administration Map, Land Use Map, Slope Slope Map, and Soil Type Map in Kesugihan District. The measurement of soil chemical properties uses the method commonly used by the Soil Laboratory of the Unsoed Faculty of Agriculture. The results of the analysis of the chemical properties of the soil in the Kesugihan rice fields showed that the average soil pH was neutral, the electrical conductivity was very low, the average redox potential was in the moderately reduced class, the C-organic content was very low (0.02-0.18 %), available sulfur content is available low (21-46 ppm). Fertilization recommendation to increase sulfur nutrients in Kesugihan with ZA fertilizer is 63.68 kg ZA/ha. Fertilization recommendations to increase soil C-Organic in Kesugihan District with manure of 7-8 tons/ha. Keywords : C-Organic, Sulfur, Fertilizer Recommendation, Rice |
