Abstract

ABSTRAK Tujuan penelitian adalah untuk mengidentifikasi sifat kimia tanah dan merekomendasikan pemupukan N, P dan K di lahan sawah pasang surut pada tanaman padi. Pengambilan sampel penelitian dilaksanakan di Kelurahan Setapuk Besar Kecamatan Singkawang Utara Kota Singkawang.  Parameter dalam penelitian ini adalah N-Total, P (tersedia), K tersedia, Ca-dd, Mg-dd tanah, Reaksi tanah (pH), C-organik, Al-dd, Salinitas, Uji Pirit dan Bobot isi Hasil analisis menunjukkan bahwa kandungan N-Total antara 0,21% - 0,38%, dengan rata-rata 0,31% termasuk dalam kriteria sedang. P-Tersedia antara 9,46 - 21,74 ppm, dengan nilai rata- rata 13,34 ppm dengan kriteria rendah. K-Tersedia antara 0,37 - 0,59 cmol (+)kg1 dengan rata -rata 0,51 cmol (+)kg1 dengan kriteria sedang.  Ca antara 4,18 - 7,44 cmol (+)kg1 dengan rata-rata 5,91 cmol (+)kg1 dengan kriteria sedang. Mg antara 1,41 - 2,68 cmol (+)kg1 dengan rata – rata = 2,36 cmol (+)kg1 termasuk dalam kriteria tinggi. Reaksi Tanah antara 4,63 – 5,95 dengan rata - rata 5,21 termasuk dalam kriteria masam. C-Organik antara 1,66 – 3,37 % dengan rata-rata 2,62 termasuk dalam kriteria sedang. Kejenuhan Al yang ada dilokasi penelitian menunjukkan kriteria sangat rendah. Salinitas antara 555 – 644 ppm dengan rata-rata 585 ppm termasuk dalam kriteria sangat rendah. Uji Pirit menunjukan bahwa tidak ditemukan kandungan Pirit pada kedalaman 0-20 cm. Bobot isi tanah antara 0,77 – 0,95 gr/cm3 dengan rata-rata 0,87 gr/cm3. Berdasarkan hasil perhitungan rata-rata kebutuhan pupuk dilokasi penelitian, kebutuhan N 128,45 kg/ha (279,25 kg/ha Urea), P2O5 113,92 kg/ha (316,43 kg/ha Sp-36) dan K2O 36 kg/ha (60 kg/ha KCl).   Kata kunci : Sifat kimia tanah, lahan sawah pasang surut dan rekomendasi pemupukan

Abstract

ABSTRACTRice straw is one of agricultural waste that has the potential to add nutrients in the soil. to accelerate the composting process is treated the role of microorganisms such as trichoderma sp and manure. the aim of this research is to know the effect of giving straw compost types with Trichoderma Stimulator and manure to P-available and growth of corn plant (Zea mays L.) on Ultisol soil. This research was conducted from February 25, 2017 to August 13, 2017. Complete Random Design (RAL) design consists of 4 treatments with 5 replications, 2 sets of plants so that the number of plants as many as 40 plants, this research was conducted in the experimental garden of Mount Meliau Garden Four Afdeling Meliau Sub-district, Sanggau District. the treatment is coded K0 (without compost), K1 (compost (straw + tricoderma)), K2 (compost (straw + tricoderma + manure)), K3 (compost (straw + manure)). The results showed that the effect of several straw compost with Trichoderma Stimulator and manure differed significantly on the growth of corn plant (Zea mays L.), but had no significant effect on the availability of P-soil in maize. Keywords: Ultisol, Rice Straw Compost, Trichoderma sp., Corn
