Abstract

ABSTRACT : Land is a natural resource which is very important foragriculture and. This study aims to determine the level of land suitability classes as well as inhibited factorsfor orange fruit crop. Land to be evaluated is located in the village of Semelagi Kecil district Singkawang Utara. Parameter study include ; state of the environment, physic, and chemical properties of the soil. The environment factors are and topography, climate, the flooding , drainage, land use. Soil physic properties observed color of soil, soil texture and structure of soil, groundwater level, depth of sulfidic and effective depth, ripeness soil,and kosistensi soil. Soil chemical properties in laboratory analysis, including pH, CEC, KB, Organic C, total-N, P, K, Ca, mg and Salinity.The results showed that among the sites there are two soil mapping unit (SPT) is Typic Endoaquepts that have actual land suitability classes S3.b, potential land class suitability S1with a land area of ± 125 ha of the total area of "‹"‹the research sites.Recommended management consists of recommendations for improvement of drainage and guludan, liming, fertilizzation. Drainage improvements as it has drainage freewheeling, the ground water level ranges from >120 cm. Soil pH 5,62, need to improved with liming and fertilizzation. The calculation is done based on the levels of Al -dd at the ground surface. Lime used is Calsit limestone (CaCO3). In SPT lime and fertilizer needs can be given in accordance with the recommendations of the government in general. Key word : Orange, Land Suitability Evaluation.

STUDI STATUS HARA NITROGEN, FOSFOR, DAN KALIUM PADA TANAH BERGAMBUT UNTUK TANAMAN LADA (Piper nigrum L.) DI KECAMATAN SUNGAI KUNYIT KABUPATEN MEMPAWAH Ristha Febrianti(1), Denah Suswati(2), Rini Hazriani(2) (1)Mahasiswa Fakultas Pertanian, Universitas Tanjungpura (2)Dosen Fakultas Pertanian, Universitas Tanjungpura Pontianak ABSTRAK Studi status hara merupakan proses untuk mengetahui kandungan unsur hara yang ada di dalam tanah untuk pertumbuhan tanaman. Studi status hara melibatkan pelaksanaan survey dan analisis pemupukan untuk meningkatkan kesuburan tanah. Penelitian ini bertujuan untuk mengetahui status hara Nitrogen, Fosfor dan Kalium serta merekomendasi pemberian pupuk Urea, SP-36, dan KCL pada tanah bergambut untuk meningkatkan produksi lada. Hasil rekomendasi menunjukkan bahwa status hara Nitrogen, fosfor, dan Kalium pada masing-masing lokasi LT.1, LT.2, dan LT.3 bervariasi dari yang sangat rendah sampai sangat tinggi. Pada masing-masing lokasi dalam rangka meningkatkan produksi tanaman lada, direkomendasikan untuk melakukan pemupukan dengan pupuk Urea, SP-36 dan KCl. Pada lokasi LT.1 urea (170,35 kg/ha), SP-36 (42,85 kg/ha), KCl (603,08 kg/ha). Lokasi LT.2 urea (169,73 kg/ha), SP-36 (214 kg/ha), KCl (559,03 kg/ha). Lokasi LT.3 urea (174,90 kg/ha), SP-36 (165,98 kg/ha), KCl (510,11 kg/ha). Kata Kunci : Status Hara, Tanah Bergambut, Lada
