ABSTRAK
Lahan sawah irigasi yang pengelolaannya dilakukan secara intensif dan
berlangsung lama menyebabkan status kesuburan tanahnya menurun. Penelitian ini
bertujuan untuk mengetahui sifat kimia tanah dan mengkaji kesuburan tanah pada
lahan sawah irigasi di Kabupaten Sleman. Metode yang digunakan untuk
menentukan lokasi penelitian adalah metode suvey lapangan dengan analisis
laboratorium. Pengambilan sampel didasarkan pada 3 ketinggian tempat yakni 500
mdpl, 350 mdpl dan 200 mdpl. Setiap ketinggian tempat diambil 3 sampel secara
purposive sebagai ulangan. Sampel tanah dianalisis sifat-sifat tanahnya sebagai
parameter yang digunakan untuk menentukan kriteria kesuburan tanah menurut
Pusat Penelitan Tanah Bogor (1995) dan dianalisis di Laboratorium Prodi Ilmu
Tanah Fakultas Pertanian UPN “Veteran” Yogyakarta. Parameter yang dianalisis
yaitu : pH, C-organik, N-total, Rasio C/N, P-potensial, K-potensial, Kapasitas
Tukar Kation (KTK) dan Kejenuhan Basa (KB). Hasil penelitian pada lahan sawah
di Kabupaten Sleman menunjukkan bahwa rata-rata pH 6,3 (agak masam), C�organik 1,35% (rendah), N total 0,25 (sangat rendah), P potensial 6,63 me% (sangat
rendah), K potensial 2,17 me% (sangat rendah), KTK 3,49 me% (sangat rendah)
dan KB 73,45% (sangat tinggi). Status kesuburan tanah pada lahan sawah di daerah
penelitian umumnya sangat rendah, kecuali pada lahan sawah yang mempunyai
tinggi tempat 200 mdpl yang memiliki tingkat kesuburan rendah.
Kata kunci: Kabupaten Sleman, sifat kimia tanah, status kesuburan tanah, tanah
sawah.
STUDY ON SOIL FERTILITY OF IRRIGATED RICE FIELD
IN SLEMAN REGENCY,
DAERAH ISTIMEWA YOGYAKARTA

ABSTRACT
Irrigated rice fields whose management is carried out intensively and for a long
time cause the status fertility to decline. This study aims to determined the chemical
properties of the soil and assess soil fertility in irrigated rice fields in Sleman Regency.
The method used to determine the research location is a field survey method with
laboratory analysis. Sampling was based on 3 altitudes, namely 500 masl, 350 masl and
200 masl. For each altitude, 3 samples were taken purposively as replication. Soil
samples were analyzed for soil properties as parameters used to determine soil fertility
criteria according to Bogor Soil Reasearch Center (1995) and analyzed at the
Laboratory of Soil Science Study Program, Faculty of Agriculture, UPN “Veteran”
Yogyakarta. The parameters analyzed were: pH, Organic Carbon (C organic),
Nitrogen (N total), C/N, P-potential, K-potential, Cation exchange Capacity (CEC) and
Base Saturation (BS). The result of the research on rice fields in Sleman Regency
showed that pH was 6.3 (slighly acidic), organic C was 1.35% (low), N total was 0.25
(medium), C/N was 5.61 (low), P-potential was 6.63 me% (very low), K-potential was
2.17 me% (very low), CEC was 3.49 me% (very low) and BS was 73.45% (very high).
Soil ferility status in paddy fields of the research area in Sleman Regency is generally
very low, except for the rice fields at 200 masl have low fertility levels.
