Abstract

Fly ash berpotensi digunakan sebagai pembenah tanah dan  sumber hara tanaman, karena bersifat basa (pH 8-12), kadar hara silika tinggi, mengandung hara makro dan mikro yang dibutuhkan tanam. Penelitian bertujuan untuk mengetahui pengaruh aplikasi fly ash terhadap  kadar hara makro, silika dan logam berat pada tanah, tanaman, dan gabah serta hasil padi sawah.  Penelitian dilaksanakan dari bulan Juni-Desember 2024. Penelitian disusun dalam Rancangan Acak Kelompok  9 ulangan dan  3 perlakuan (Tanpa fly ash, 5 ton fly ash+1 ton pupuk kandang/ha, dan 5 ton fly ash/ha). Variabel yang diamati yaitu: 1) sifat kimia tanah dan kandungan logam berat sebelum dan sesudah perlakuan, 2) kadar hara makro, silika dan logam berat  dalam jaringan tanaman dan gabah, 3) pertumbuhan tanaman, komponen hasil, dan hasil/ha. Hasil penelitian menunjukkan bahwa tingkat kesuburan tanah tergolong rendah. Pemberian fly ash meningkatkan   C-organik,  P-total,  P-tersedia, Si-tersedia dan dan menurunkan kadar logam berat. Aplikasi fly ash meningkatkan kadar Si tanaman dan menurunkan kadar logam berat dalam jaringan tanaman dan gabah, meningkatkan anakan produktif dan hasil. Hasil tertinggi (8 t GKP/ha) didapatkan pada perlakuan 5 ton fly ash + 1 ton pupuk kandang/ha.

Abstract

Soil fertility is one of the primary aspects determining agricultural productivity, especially in tropical mineral soils, where nutrient constraints frequently limit crop growth and yield. This study aimed to (a) assess and map the Soil Fertility Index (SFI) across different land units, (b) evaluate soil characteristics, and (c) analyze the major factors influencing soil fertility. A total of 21 soil samples from 14 land units were studied. The SFI was calculated using seven key soil chemical properties: pH, organic matter, phosphorus, potassium, calcium, magnesium, and aluminum. The results showed that soil fertility in the study area was generally low, with a mean SFI value of 21.53. Among the land units, two were classified as very low, nine as low, and three as moderate fertility. The lowest SFI (16.14) was observed in land unit pTls.2.Kc, while the highest (26.78) occurred in pTps.2.Hs. Only 34.50% of the area exhibited moderate fertility, with the remainder classified as low to very low. Principal component analysis revealed that four components accounted for 81.36% of the total variance, with the dominant factors ranked as follows: CEC>base saturation>aluminum saturation>K>Mg>Ca>Na>P>pH>soil organic carbon. High annual rainfall (5,064 mm/year) and predominantly moderately steep to steep slopes were the main agroclimatic and physical constraints limiting land use. The study highlighted that the SFI is effective in representing soil fertility status in tropical soils. The integration of suitable crops that are adapted to ecological conditions and the improvement of soil fertility based on key controlling factors are essential for utilizing the land.
