Abstract

Sandy soil is part of the soil fraction with low nutrient content, organic matter, and cation exchange capacity. This is due to the leaching process so that nutrients are easily lost. The research aimed to improve the chemical characteristics of sandy soil and rice crop production due to the application of humic acid and silica. This research used of Completely Randomized Design method using soil amendment materials, namely humic acid (A) at the of 60 kg/ha and silica (S) at the of 5 tons/ha consisting of 6 combinations of comparisons repeated 4 times. Variables of analysis parameters include pH, cation exchange capacity, organic matter, N-NH4+, N-NO3- and rice crop production. The data obtained were analyzed by analysis  of variance (ANOVA). If the results showed a significant effect, it was continued with the Honestly Significant Difference (HSD) test at the 5% level. The results showed that the application of soil amendment in the from humic acid and silica with various treatments on sandy soil was only able to improve CEC by 3,18% and Organic-C by 0,08%. In contrast soil pH and N-available didn`t give significant results in improving soil chemical properties and rice crop production. It`s recommended to conduct further research on the dose used in soil amendments so that it can effect nitrogen parameters and rice crop production in sandy soil.  Keywords: humic acid, silica, sandy soil

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh pemberian jenis bahan organik dan dosis biochar serbuk kayu terhadap sifat kimia tanah Entisol di Desa Sedayulawas, Lamongan serta untuk mengkaji jenis perlakuan jenis bahan organik dan dosis biochar serbuk kayu yang sangat berpengaruh untuk memperbaiki kesuburan kimia tanah entisol. Penelitian ini dilaksanakan di Laboratorium Sumber Daya Lahan Universitas Pembangunan Nasional “Veteran” Jawa Timur pada April sampai Juli 2023. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial dengan 2 faktor dan 3 ulangan dengan inteval 20, 40 dan 60 hari. Faktor pertama adalah jenis bahan organik (K), terdiri atas : Kontrol, Seresah Daun 45 g/polybag (K1), Cangkang Telur 45 g/polybag (K2) dan Kotoran Kambing 45g/polybag (K3). Faktor kedua dosis biochar serbuk kayu, terdiri atas : 15 g/polybag (S1), 20 g/polybag (S2) dan 30 g/polybag (S3). Hasil penelitian menunjukkan bahwa perlakuan cangkang telur 45g/polybag tanpa dosis biochar serbuk kayu menghasilkan penurunan pH tanah Entisol. Perlakuan tanpa bahan organik dan dosis serbuk kayu 30g/polybag menghasilkan nilai tertinggi pada C-organik tanah Entisol. Perlakuan Kotoran Kambing 45g/polybag dan dosis biochar serbuk kayu 15g/polybag menghasilkan nilai tertinggi pada N-total tanah Entisol.
