Abstract

AbstrakPenelitian dilaksanakan di Desa Tri Kembang dengan luas lahan ± 6 ha pada lahan pasang surut khususnya pada tanaman lada. Penelitian dilakukan pada lahan petani yang terdiri dari 4 pemilik lahan  dengan tujuan  penelitian untuk Mengetahui status hara nitrogen (N), fosfor (P), kalium (K) dan saran pemupukan N, P dan K pada tanaman lada dengan metode survey dan wawancara pada petani yang lahannya diambil sebagai sampel di lokasi penelitian untuk mengetahui teknik budidaya yang digunakan, cara pengolahan tanah, pemupukan, waktu aplikasi, pemeliharaan (pengendalian gulma dan pengendalian hama penyakit tanaman), dan waktu panen. Variabel penelitian yang diamati adalah Reaksi tanah (pH), C-organik Tanah, N–Total, P-tersedia, K-dd, Ca-dd, Mg-dd, Na-dd  KTK, KB, Pirit, Kedalaman Muka Air Tanah, Tekstur Tanah dan Bobot isi. Berdasarkan hasil analisis yang dilakukan dapat simpulkan bahwa : pH pada lokasi penelitian rata-rata 4,10 yang termasuk dalam kriteria sangat masam, Ca-dd Tanah, Mg-dd Tanah dan Kejenuhan Basa Tanah masing – masing dengan nilai rata – rata 1,17 Cmol(+)kg-1,0,48 Cmol(+)kg-1, 19,05%, termasuk dalam kriteria sangat rendah, C-Organik Tanah, N-Total Tanah, K-dd Tanah dan KTK-Tanah masing – masing dengan nilai rata – rata 1,52%, 0,19%, 0,26 Cmol(+)kg-1, 11,21 Cmol(+)kg-1, termasuk dalam kriteria rendah, Na-dd Tanah dengan rata –rata 0,54 termasuk dalam kriteria sedang dan P-Tersedia Tanah dengan rata – rata 110,66, termasuk dalam kriteria sangat tinggi. Muka Air Tanah pada lokasi penelitian rata-rata 62,35 termasuk dalam kriteria agak dalam, Uji pirit  pada kedalaman 0 – 30cm  berbuih, berbau dan berasap, Tekstur Tanah liat berdebu dan Bobot isi pada 4 lokasi penelitian dengan nilai rata – rata 0,95 termasuk dalam kriteria sedang. Hasil perhitungan kebutuhan pupuk di lokasi penelitian masing – masing adalah Urea 1.185,75kg/ha/tahun, SP-36 314,73 kg/ha/tahun dan KCL 1.240,15 kg/ha.tahun.  Kata kunci : lada, lahan pasang surut, sifat kimia tanah.

Abstract

Based on West Kalimantan BPS data for 2017, West Kalimantan has 1,543,752 ha of peatlands spread across several districts. One district that has peatlands is Kubu Raya Regency where the peatlands in this region are 130,248 ha. the purpose of this study was to determine the chemical nature of the soil and the fertility status of peat soils in several types of land use for oil palm, rubber, and horticulture.The location of this research is in Rasau Jaya III Village, Rasau Jaya Sub-District, Kubu Raya District. This research was conducted from May to July from the start of preparation, field sampling, soil analysis in the laboratory to the presentation of results. The parameters in this study are, ground water table, pyrite, N-total, P-total, K-total, C-organic, soil pH, C/N ratio, cation exchange capacity, base saturation and bulk density.The results of the analysis showed that the ground water table in the upper layer in each study area included shallow criteria while for the lower layer had rather deep criteria. Pyrite at the study site was no sulfidic. N-total between 0.21-0.45% with very low criteria. P-total between 0.93-3.94 mg / 100g with very low to low criteria. K-total between 0.98-3.98 mg / 100g with very low to low criteria. C-Organic between 4.94-12.96 mg / 100g with very high criteria. Soil pH between 2.65-3.01 with very acid criteria. C/N Ratio between 1.03-5.70% with very low criteria. Cation exchange capacity between 60.74-103.82 cmol (+) kg-1 with very high criteria. Base saturation between 9.41-16.58% with very low criteria. Bulk density from 0.15-0.34 gram / cm3. From the results of this analysis obtained criteria of soil fertility which are classified as low criteria.       Keywords: Chemical properties, fertility status  peat soils
