Abstract

Vertisols contain clay minerals that expand significantly during the rainy season and shrink during the dry season. This condition causes changes in the availability of water and soil ions. This study aimed to examine the effect of adding organic matter (OM) and sand on changes in vertisols and plant growth. The study was conducted using a factorial Randomized Block Design (RBD). The first factor was 5 kinds of OM: control (B0), 15 tons of banana peel compost ha⁻¹ + cow dung (10:1) (B1), 15 tons of leaf litter compost ha⁻¹ (B2), 15 tons of water hyacinth compost ha⁻¹ + cow dung (1:1) (B3), and 1 ton of biochar ha⁻¹ (B4). The second factor was the provision of sand as much as 3 level, namely: 0% (P0), 20% (P1), and 40% (P2). Each treatment combination was repeated 3 times. Sweet corn was used as a growth indicator. The observed soil chemical parameters were soil pH, organic C, NH₄⁺ and NO₃⁻, and Cation Exchange Capacity (CEC) using standard methods. Leaf area was measured using the Arnon method. The results showed providing banana peel compost + cow dung with 40% sand increased the best NO₃⁻ and soil pH levels. The highest soil C-organic content was found in the treatment with aloe vera compost + cow dung and 0% sand. The best leaf area and plant chlorophyll levels were achieved using banana peel compost + cow dung with 20% sand.

Abstract

Vertisol has a high clay content which causes this soil to expand if wet and wrinkle if dry. The fertility level of vertisol is relatively low, so it is necessary to improve soil quality through the provision of organic matter and sand. This study was prepared based on the Complete Random Design (RAL) Factorial consisting o[1]f two factors. The first factor is 4 kinds of organic matter (B) consisting of control (B0), banana peel compost + cow dung (10:1) (B1), leaf litter compost (B2), and hyacinth compost + cow dung (B3). Compost is applied at a dose of 15 tons.ha-1. The second factor is the three percentages of sand material (P) consisting of 0% (P0), 20% (P1), and 40% (P2). The chemical characteristics of the soil analyzed are pH, c-organic, n-available, p-available, and CEC. The results showed that the application of organic matter and sand had a significant effect on c-organic and nitrate. While at pH, ammonium, p-available, and CEC have no significant effect. Key-words: Vertisol, soil improver, chemical characteristicsINTISARI Vertisol mempunyai kandungan liat yang tinggi yang mengakibatkan tanah ini mengembang jika basah dan mengkerut jika kering. Tingkat kesuburan vertisol tergolong rendah, sehingga perlu adanya perbaikan kualitas tanah melaui pemberian bahan organic dan pasir. Penelitian ini disusun berdasarkan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri dari dua factor. Factor pertama yaitu 4 macam bahan organik (B) yang terdiri dari kontrol (B0), kompos kulit pisang + kotoran sapi (10:1) (B1), kompos serasah daun (B2), dan kompos eceng gondok + kotoran sapi (B3). Kompos diaplikasikan dnegan dosis 15 ton.ha-1. Faktor kedua yaitu tiga persentase pemberian material pasir (P) yang terdiri dari 0% (P0), 20% (P1), dan 40% (P2). Karakteristik kimia tanah yang dianalisis yaitu pH, c-organik, n-tersedia, p-tersedia, dan KTK. Hasil penelitian menunjukkan bahwa pemberian bahan organic dan pasir memberikan pengaruh secara nyata terhadap c-organik dan nitrat. Sedangkan pada pH, amonium, p-tersedia, dan KTK tidak memberikan pengaruh nyata. Kata kunci: Vertisol, Pembenah Tanah, Karakteristik Kimia
