PENGARUH APLIKASI PUPUK KASCING DAN ZEOLIT SEBAGAI
PEMBENAH TANAH TERHADAP KETERSEDIAAN NITROGEN
TANAH SALIN

ABSTRAK
Tanah salin berpotensi besar untuk produksi pertanian, tetapi memiliki kendala
pada status ketersediaan hara dan kemampuan menyimpan hara yang rendah.
Penelitian ini bertujuan untuk mengetahui pengaruh pemberian kascing dan zeolit
terhadap ketersediaan N tanah salin. Penelitian dilaksanakan dirumah kaca
Fakultas Pertanian UPN “Veteran” Yogyakarta dengan menggunakan Rancangan
Acak Lengkap dua faktor. Faktor pertama kascing terdiri atas tiga aras: 0 ton/ha
(K0), 15 ton/ha (K1), dan 20 ton/ha (K2). Faktor kedua zeolit terdiri atas tiga aras:
0 ton/ha (Z0), 5 ton/ha (Z1), 10 ton/ha (Z2). Setiap kombinasi perlakuan diulang
sebanyak tiga kali. Pengambian sampel tanah dilakukan disekitar Pantai Ambal,
Kebumen. Selanjutnya melakukan pengisian paralon dengan kombinasi tanah,
pupuk kascing, zeolit, dan ZA sesuai perlakuan pada setiap unit percobaan. Ukuran
paralon tinggi 30 cm, diameter 9 cm, tinggi tanah dalam paralon 20 cm. Setiap
perlakuan diinkubasi selama 45 hari. Setelah inkubasi selesai dilakukan pelindian
menggunakan aquades. Selanjutnya dilakukan pengambilan sampel akhir tanah
yang dibagi menjadi dua bagian yaitu tanah bagian atas (0-10 cm) dan tanah bagian
bawah (10-20 cm) dan dilakukan analisis di laboratorium. Parameter analisis
pendahuluan terdiri atas tekstur, DHL, berat volume, pH H2O, N-total, C-organik,
N-tersedia, dan KPK pada tanah, pH H2O, N-total, C-organik, dan N-tersedia pada
kascing, pH, N-Total, N-Tersedia pada ZA serta KPK pada zeolit. Parameter
setelah inkubasi terdiri atas pH H2O, N-tersedia, DHL pada tanah bagian atas dan
bawah serta pH, DHL, NH4+ dan NO3_ pada air lindi. Data dianalisis menggunakan
ANOVA dan dilanjutkan DMRT taraf 5%. Hasil analisis menunjukkan bahwa
kascing berpengaruh nyata terhadap pH H2O, DHL, N-Tersedia (NH4+ dan NO3-)
tanah, pH air lindi, dan DHL air lindi, serta tidak berpengaruh secara nyata pada
NH4+ dan NO3- air lindi. Pada zeolit berpengaruh nyata terhadap pH H2O, DHL,
N-Tersedia tanah, pH air lindi, dan DHL air lindi, serta tidak berpengaruh secara
nyata pada N-NH4+ dan NO3- air lindi. Pada kombinasi kascing dan zeolit
berpengaruh nyata terhadap pH H2O, DHL tanah, N-Tersedia tanah bagian atas,
DHL dan pH air lindi, serta berpengaruh tidak nyata pada N-Tersedia tanah bagian
bawah, NH4+ dan NO3- air lindi.

EFFECT OF APPLICATION VERMICOMPOST FERTILIZER AND
ZEOLITE AS SOIL CONDITIONERS FOR THE AVAILABILITY OF
NITROGEN SALINE SOILS

ABSTRACT
Saline soil has great potential for agricultural production, but has problems with the
status of nutrient availability and low nutrient storage capacity. This research aims
to determine the effect of vermicompost and zeolite on N availability in saline soil.
The research was carried out in the greenhouse of the Faculty of Agriculture, UPN
"Veteran" Yogyakarta using a two factor Completely Randomized Design. The first
factor was vermicompost consists of three levels: 0 tons/ha (K0), 15 tons/ha (K1),
and 20 tons/ha (K2). The second factor was zeolite consists of three levels: 0 tons/ha
(Z0), 5 tons/ha (Z1), 10 tons/ha (Z2). Each treatment combination was repeated
three times. Soil samples were taken around Ambal Beach, Kebumen. Next, fill the
paralon with a combination of soil, vermicompost fertilizer, zeolite, and ZA
according to the treatment in each experimental unit. The size of the paralon is 30
cm high, 9 cm in diameter, the height of the ground inside the paralon is 20 cm.
Each treatment was incubated for 45 days. After incubation is complete, leaching
is carried out using aquades. Next, the final soil sample is taken which is divided
into two parts, namely the top soil and bottom soil and the analysis is carried out in
the laboratory according to the final parameters. Preliminary analysis parameters
consist of texture, EC, bulk density, pH H2O, N-totals, C-organic, available N, and
CEC in soil, pH H2O, N-total, C-organic, and available N in vermicompost, pH, N-
Totals, Available N in ZA and CEC in zeolite. Parameters after treatment consist
of pH H2O, available N, N-totals in the top and bottom soil as well as leached pH,
EC, NH4+ and NO3-. Data were analyzed using ANOVA and continued with DMRT
at 5% level. The results of the analysis showed that vermicompost had a significant
effect on the pH H2O, EC, Available N (NH4+ and NO3-) in the soil, leached pH and
EC, and had no significant effect on leached NH4+ and NO3-. Zeolite has a
significant effect on the pH H2O, EC, Available N in the soil, leached pH and EC,
and has no significant effect on leached NH4+ and NO3-. The combination of
vermicompost and zeolite has a significant effect on the pH H2O and EC of the top
and bottom soil, available N in the top soil, leached EC and pH, and has no
significant effect on the available N of the bottom soil, leached NH4+ and NO3- .
