Mahuze, Martha (2013) Pengaruh Pemberian Kascing Pakan Daun Lamtoro (Leucaena Leucocephala) Terhadap Kandungan Nitrogen Pada Alfisol. Sarjana thesis, Universitas Brawijaya.
Abstract
Pemberian pupuk kascing pada tanah secara fisik memperbaiki struktur tanah, porositas, permeabilitas, dan meningkatkan kemampuan daya menahan air dan secara kimia meningkatkan kemampuan menyerap kation, sumber hara makro dan mikro serta meningkapatakan pH pada tanah masam. Alfisol merupakan tanah mineral yang telah mengalami perkembangan lanjut, bertekstur liat, mempunyai kandungan bahan organik rendah (berkisar antara 0,15% sampai 1,25 %), reaksi tanah agak masam sampai alkalis dan kejenuhan basa lebih dari 35%. Alfisol banyak digunakan untuk budidaya tanaman hortikultura sehingga banyak unsur hara (terutama N dan P) yang terangkut keluar dari lahan. Tujuan penelitian adalah: 1) Untuk mengetahui pengaruh pemberian kascing pakan daun lamtoro terhadap kandungan N pada Alfisol dan 2) Untuk mengetahui pengaruh pemberian kascing pakan daun lamtoro dengan dosis yang berbeda terhadap kandungan N pada Alfisol. Penelitian dilakukan di rumah kaca Fakultas Pertanian Universitas Brawijaya pada bulan Mei sampai September 2011. Penelitian menggunakan metode Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dosis kascing (kontrol, 5 ton ha-1, 10 ton ha-1, 15 ton ha-1 dan 20 ton ha-1).. Pelaksanaan penelitian meliputi: analisa dasar tanah, persiapan media tanah (dari Desa Mulyo Agung, Kecamatan Dau, Malang), pembuatan kascing pakan daun lamtoro, perlakuan inkubasi dan aplikasi pemupukan. Parameter yang diukur adalah pH (H2O), N-total, N tersedia (NH4+ dan NO3-). Pengamatan tanah setiap parameter dilakukan pada 1 – 6 MSI dan tanah 6 MST. Data dianalisis statistik dengan uji F taraf 5 %, kemudian dilanjutkan uji Duncan serta uji korelasi untuk mengetahui keeratan hubungan antar parameter. Hasil penelitian menunjukan bahwa pemberian kascing pakan daun lamtoro nyata meningkatkan N Alfisol seiring dengan peningkatan dosis kascing. Kandungan NH4+ tertinggi pada dosis perlakuan K20 4 MSI (0,621 ppm), NO3- pada dosis K20 6 MSI (0,190 ppm) dan N-total tanah pada K20 4 MSI (0,28%). Pemberian kascing pakan daun lamtoro meningkatkan kandungan N tanah dengan kandungan tertinggi terjadi pada perlakuan dosis 20 ton ha-1 sebesar 235,80% (NH4+), 106,52% (NO3-) dan 100% ( N-total) bila dibandingkan dengan kontrol.
English Abstract
The using of casting fertilizer can improve soil physical soil structure, porosity, permeability, and increase the ability to retain water. Chemically, can improve the ability to absorb cations, source of macro and micro nutrients and improve pH in acid soils. Alfisol is mineral soil that has undergone further development, loamy textured, have low organic matter content (ranging from 0.15% to 1.25%), the reaction is slightly acid to alkaline soil and base saturation of more than 35%. Alfisol widely used for the cultivation of horticultural crops so many nutrients (especially N and P) are transported out of the land. Research objectives are: 1) To determine the effect of lamtoro leaf feed casting N content in the Alfisol and 2) To determine the effect of lamtoro leaves feed casting with different doses of the N content in the Alfisol. This research was done in the greenhouse Brawijaya University in May until September 2011. Research using completely randomized design (CRD) with 5 doses of casting treatment (control, 5 ton ha-1, 10 ton ha-1, 15 t ha-1 and 20 ton ha-1). Implementation of the study include: basic soil analysis, soil media preparation (from village Mulyo Supreme, District Dau, Malang), making casting feed lamtoro leaves, incubation treatment and fertilizer application. The parameters measured were pH (H2O), total-N, available N (NH4+ and NO3-). Soil parameter observations was done every week 1 - 6 weeks after incubation and after planted. Data were analyzed statistically by F test level of 5%, then followed Duncan test and correlation test to determine the relationship between parameters. The results showed that using of lamtoro leaf feed casting N Alfisol significantly increased with increasing doses of casting. The highest content of NH4+ treatment at a dose of 4 MSI K20 (0,621 ppm), at a dose of NO3- K20 6 MSI (0.190 ppm) and total N soil at K20 4 MSI (0.28%). The giving of lamtoro leaf feed casting could increase soil N content with highest occurs at dose of 20 ton ha-1 treatment with 235.80% (NH4+), 106.52% (NO3-) and 100% (total N) when compared with controls .
