Abstract

Entisols had a great potential for maize planting area expansion in increasing its production. The low soil fertility could be improved by application of coastal sediment. This current research examined the effect of different amount of coastal sediment on nutrient availability and maize production on Entisols, West Kalimantan. The research was conducted from July to November, 2013 in green house, Faculty of Agriculture, Tanjungpura University, West Kalimantan. The treatment conducted was the application of coastal sediment at dosage of: 0 Mg ha-1 (L0), 14 Mg ha-1 (L1), 28 Mg ha-1 (L2), 42 Mg ha-1 (L3), 56 Mg ha-1 (L4), 72 ton ha-1 (L5), 86 Mg ha-1 (L6) and 100 Mg ha-1 (L7). The treatments were arranged by completely randomized design with 3 replications. Research results showed that 42 Mg ha-1 coastal sediment was the best treatment and able to increase soil nutrients availability and maize productivity. The provision of coastal sediment increased the availability of K, Ca, Mg and Na, also the availability of nutrients in accordance with the increase of the dosage of coastal sediment.

Abstract

KAJIAN MIKROBIA PELARUT FOSFAT PADA BEBERAPA PENGGUNAAN LAHAN DI DESA ROBAN, KOTA SINGKAWANG Muhammad Shalleh(1), Saeri Sagiman(2), Sulakhudin(2) (1)Mahasiswa Fakultas Pertanian dan (2)Staf  Pengajar dari Program Studi Ilmu Tanah Fakultas Pertanian Universitas Tanjungpura Pontianak ABSTRAKFosfat (P) merupakan unsur hara esensial kedua setelah nitrogen yang berperan penting pada pertumbuhan tanaman. Ketersedian P di dalam tanah rendah oleh karena mudah terikat oleh unsur lain Fe, Al, Ca dan Mg. Beberapa mikrobia mampu melarutkan P sehingga peranannya sangat penting dalam budidaya tanaman. Tujuan penelitian untuk mengetahui jumlah populasi mikrobia pelarut fosfat (MPF), mengidentifikasi jenis serta kemampuannya dalam melarutkan fosfat yang diisolasi dari beberapa penggunaan lahan yakni lahan hutan sekunder, lahan pasca penambangan emas tanpa izin (PETI) tanpa tanaman dan lahan pasca PETI yang ditanami kelapa sawit di Desa Roban, Kota Singkawang. Isolasi MPF dilakukan  menggunakan media pikovskaya Ca3(PO4)2 dan FePO4 sebagai sumber P. Penghitungan kepadatan MPF dengan metode cawan hitung (total plate count). Hasil penelitian menunjukkan bahwa hanya ditemukan bakteri pelarut fosfat (BPF) pada sumber P Ca3(PO4)2 yakni isolat SP1, SP2,SP3, SP4 dan SP5. Cendawan pelarut fosfat (CPF) ditemukan pada sumber P media pikovskaya ikatan Ca3(PO4)2 dan FePO4. Isolat CPF Ca3(PO4)2 yakni SP1, SP2 dan SP3. Isolat CPF FePO4 yakni SP10.1 dan SP10.2. Isolat BPF yang memiliki indeks pelarutan P terbesar adalah SP1 sebesar 69 mm2. Isolat CPF Ca3(PO4)2 memiliki indeks pelarutan terbesar adalah SP3 sebesar 105 mm2 sedangkan pada isolat CPF FePO4 adalah SP10.1 sebesar 46 mm2. Kepadatan populasi BPF menurun setelah adanya kegiatan PETI sedangkan populasi cendawan meningkat di lokasi pasca PETI tanpa tanaman.Kata kunci : Fosfat, hutan sekunder, sawit, bakteri, cendawan.

Abstract

This study aimed to determine the effect of coastal sediment on peat soil for soybean planting medium to soil chemical properties and CO2 emissions. The research lasted for 3 months starting from preparation to presentation of the results. This research was conducted at the Laboratory of Soil Quality and Health, Laboratory of Chemistry and Soil Fertility and in the Faculty of Agriculture experimental garden Tanjungpura University. The method used is experiment with a completely randomized design (CRD), which consists of 5 treatments and 4 replications. Each polybag contained 1 plant sample. So the number of plants altogether 20 units of the plant. Treatment as follows: LL0 : Without treatment coastal sediment, LL1 : coastal sediment 25.2 tonnes/ha equivalent to 180 g/polybag, LL2 : coastal sediment 33.6 tonnes/ha equivalent to 240 g/polybag, LL3 : coastal sediment 42 ton / ha equivalent to 300 grams/polybag, LL4 : coastal sediment 50.4 tonnes/ha equivalent to 360 g/polybag. The variables observed in this study are soil pH, cation exchange capacity (CEC), Base Saturation, C/N, CO2 emissions and the dry weight of soybean. The results showed that application   of coastal sediment with various doses on peat soil can increase soil pH, Base Saturation and C/N ratio, with decreasing CEC. There is just a little correlation of costal sediment on CO2 emissions of soil (R2=0.0009). Coastal sediment 33.6 tonnes/ha equivalent to 240 grams/polybag was resulted dry weight of soybean   to maximum vegetative phase.
