Abstract

This research is carried on in the Village of Toho Hilir Sub-District Toho Regency Mempawah in three difrent land us, the is Crop, Bare Land and the Community Forest The purpose of this research is to know the Nutrient status of elements N,P,K, C-Organic, AL-Exchangable, CEC and Base Saturation. The point observation of this research using a system of diagonal and random with 5 spot observations of the Crops Cultivated and Forest, with depth 0-30 cm. Result of soil analysis showed that pH of the soil in the Crop Cultivated Land, Bare Land, Community Forest is high C-Organic in Land categorized as low, Bare Land is medium Crop and Community Forest is medium, N-Total in Crop Land is categorized as medium, Bare Land is medium and Community Forest also medium criteria, available phosfor on Crop Land very high, Bare Land high and Community Forest are high criteria, potassium Exchange in Crop Land is categorized as low, Bare Land including low criteria and Community Forest including low criteria, AL-Exchangable in Crop Plant Land very low in criteria, Bare Land very low and Community Forest low, CEC in Crop Land is categorized as low, Bare Land low and Community Forest low and base saturation in Crop Land is categorized as low, Bare Land very low and Community Forest very low.Keywords : Community Forest, Bare Land, Palawija, Soil Chemical Properties

Abstract

as agricultural land for the oil palm plantation sector is common so palm plantation in west kalimantan are spread in several districts ,one of them is Tayan hilir Regency. This Study aims to provide information to farmers about the characteristics and chemical and nutrient properties palm soil plantation in ultisol soil. This research carried out in the palm plantation area in the sejotang Tayan Hilir District, Sanggau Regency. The Analysis at the Laboratory of Chemistry and Soil Fertility, Faculty of Agriculture, University of Tanjungpura Pontianak. The research take 3 months, Starting from 16 April 2019 preparation to presentation of results. Based on the results of the study, the soil reaction (pH) in the study site was classified as very acidic. Textures in the study locations use code K (composite) that is K2, K3, K5 are clay texture class, K1 belongs to class of dusty clay texture and K4 is clay texture class. The Bulk density ranged from 1.06 to 1.55 gr / cm3. N-Total and C-Organic are classified as low to moderate, phosphorus and Potassium are very low to low, Ca, Mg and base saturation (KB) are very low, CEC is low and saturation of Al are very high. The level of soil fertility at the study site ask low.Keywords: Chemical Properties, Ultisols, Palm Oil.
UJI ISOLAT BAKTERI PELARUT FOSFAT ASAL KEBUN NANAS DENGAN PUPUK SP-36 TERHADAP SERAPAN P PADA TANAMAN KEDELAI (Glycine max L) DI TANAH GAMBUT Octavia, Oshin Martha; Umran, Ismahan; Alhaddad, Abdul Mujib

Abstract

ABSTRAK Tanah Gambut merupakan tanah yang terbentuk dari akumulasi bahan organik seperti sisa"“sisa jaringan tumbuhan dan hewan dan dijenuhi air yang berlangsung dalam kurun waktu yang cukup lama. Tanaman Kedelai (Glycine max L.) merupakan salah satu tanaman pangan dengan kandungan nutrisi yang tinggi. Rendahnya produksi kedelai pada lahan pertanian yang kurang optimal juga menjadikan produksi kedelai semakin menurun serta penggunaan pupuk fosfat yang terus menerus akan mengakibatkan terakumulasinya P dalam tanah dan memberikan dampak negatif terhadap lingkungan. Bakteri pelarut fosfat dapat dijadikan alternatif untuk diberikan dalam tanah, karena dapat membantu melarutkan fosfat yang tidak tersedia sehingga menjadi tersedia bagi tanaman. Tujuan dari penelitian adalah untuk mengetahui pengaruh interaksi isolat Bakteri Pelarut Fosfat (BPF) dan pupuk SP-36 terhadap serapan P pada tanaman kedelai di tanah gambut, untuk mengetahui pengaruh isolat Bakteri Pelarut Fosfat (BPF) terhadap serapan P pada tanaman kedelai di tanah gambut, dan untuk mengetahui pengaruh pupuk SP-36 terhadap serapan P pada tanaman kedelai di tanah gambut. Penelitian menggunakan Rancangan Acak Lengkap (RAL) Pola Faktorial terdiri dari dua faktor perlakuan dan tiga ulangan. Faktor pertama, yaitu isolat Bakteri Pelarut Fosfat yang terdiri dari 2 taraf. Faktor kedua, yaitu pupuk SP-36 yang terdiri dari 4 taraf sehingga semuanya terdapat 24 unit percobaan. Berdasarkan hasil penelitian Interaksi Isolat Bakteri Pelarut Fosfat (BPF) asal kebun nanas dan pupuk SP-36 dapat meningkatkan 10 % parameter berat kering tanaman dan 82 % serapan P pada tanaman kedelai. Pemberian Bakteri Pelarut Fosfat (BPF) dapat meningkatkan parameter kadar P sebanyak 32 % pada tanaman kedelai di tanah gambut dan pemberian pupuk SP-36 dapat meningkatkan parameter pH, fosfor tersedia, dan fosfor total pada tanah gambut. Kata kunci : Bakteri Pelarut Fosfat, Kedelai, Pupuk Sp-36, Tanah Gambut,
