Abstract

Smallholder coffee plantations cover a very large area on inceptisol soil with low productivity; so far, the provision of organic materials in coffee plantations is done by placing it on the surface of the soil so that it is susceptible to loss due to runoff and erosion. This study was conducted by mixing organic materials with topsoil and subsoil to determine their effect on the characteristics of topsoil and subsoil. This study used a Completely Randomized Design (CRD) with 8 treatments and 4 replications. The experimental treatments consisted of P1 (topsoil), P2 (subsoil), P3 (topsoil + Compost); P4 (subsoil + compost); P5 (topsoil + cow manure); P6 (subsoil + cow manure); P7 (topsoil + goat manure); P8 (subsoil + goat manure). The soil was incubated at field capacity conditions for 16 weeks. Soil parameters include: soil pH, soil CEC; soil organic C levels; Ca exchange, Mg exchange, K exchange, and Na exchange. The dose of organic material (cow and goat manure) is 30 tons. ha-1. Providing compost and manure can increase inceptisol soil fertility at the depth of the topsoil and bottom soil (exchangeable K, exchangeable Ca, exchangeable Mg, soil pH, Organic C, and soil CEC levels), this increase is significant compared to the control.

Abstract

Penelitian ini bertujuan mengetahui pengaruh aplikasi asam humat terhadap sifat tanah (pH, KTK, C-Organik dan P-tersedia) topsoil dan subsoil tanah inseptisol dari kebun kopi rakyat.   Penelitian ini dilaksanakan dari Oktober 2023 hingga Maret 2024. Pengambilan sampel tanah inseptisol dilakukan di kebun kopi rakyat di wilayah Karangploso, kabupaten Malang.  Percobaan inkubasi tanah di rumah kaca menggunakan rancangan acak lengkap faktorial (RALF) dengan delapan perlakuan dan empat ulangan. Kombinasi perlakuan tersusun atas faktor I Contoh tanah (yaitu topsoil dan subsoil) dan faktor II Dosis asam humat (yaitu 0, 500, 1000, dan 2000 ppm). Percobaan inkubasi berlangsung 16 minggu dan pengamatan meliputi tekstur tanah, pH tanah, kandungan C-organik, KTK tanah dan kandungan P-tersedia (P-Bray I). Hasil penelitian  menunjukkan bahwa: (1) aplikasi asam humat dapat memperbaiki karakteristik topsoil dan subsoil tanah inseptisol dari kebun kopi rakyat; (2) aplikasi asam humat berpengaruh signifikan terhadap berat kering tanaman dan serapan P tanaman jagung umur 16 minggu.
