Abstract

Inceptisol soils mainly have medium to high physical properties. However, these physical properties can be degraded if there is a limiting factor in the terrain, which is the degree of slope and low SOC. On steep slopes, soil infiltration rates decrease, which leads to the limited available soil moisture in root zone subsoil. Application of compost or manure into the soil can improve soil physical properties and increase the soil organic carbon (SOC), it improves soil porosity and improve available water capacity (AWC).  This study used the factorial completely randomized design with 8 treatments and 4 replications. The treatments included (Control + Topsoil), (Control + Subsoil), (Compost + Topsoil), (Compost + Subsoil), (Cow manure + Topsoil), (Cow manure + Subsoil), (Goat manure + Topsoil), (Goat manure + Subsoil). The results showed that (1) the addition of compost and manure can improve the physical properties of topsoil and subsoil, reducing macro porosity, increasing meso and microporosity, and increasing field capacity. (2) The addition of compost and manure can increase the water holding capacity of topsoil by 36.72% at 1 MAI to 41.12% at 5 MAI and inceptisol subsoil by 35.27% at 1 MAI to 36.42% at 5 MAI. (3) The addition of compost and manure can increase the C-organic content of topsoil by 1.62% at 1 MAI to 1.72% at 5 MAI and subsoil by 1.24% at 1 MAI to 1.38% at 5 MAI.

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 dilakukan untuk menganalisis sifat fisik tanah: kemantapan agregat tanah, bobot isi tanah, porositas tanah, konduktivitas hidrolik tanah, dan WHC (Water Holding Capacity) atau kapasitas menahan air pada zona perakaran tanaman kopi di perkebunan kopi rakyat tadah hujan. Studi lapangan dilakukan pada bulan November 2023 hingga April 2024 di kawasan perkebunan kopi rakyat tadah hujan di Kecamatan Karangploso, Kabupaten Malang. Kegiatan survei lapangan meliputi pembuatan minipit tanah, dan pengumpulan contoh tanah tidak terganggu dan contoh tanah terganggu pada kebun-kebun kopi yang berumur <5 tahun, 5-10 tahun, dan > 10 tahun, pada kedalaman tanah 20-40 cm, 40-60 cm, dan 60-80cm. Setiap kelompok umur kebun kopi diwakili oleh 5 petak pengamatan (ukuran 10 m x 10 m) yang berisi 16 pohon kopi dengan jarak tanam 3 m x 3 m. Contoh pohon kopi pada setiap petak pengamatan berjumlah 4 pohon yang berada di Tengah-tengah petak. Contoh tanah diambil pada titik pengeboran 40-50 cm dari setiap contoh pohon kopi, kemudian dikompositkan menjadi satu sampel tanah komposit yang mewakili plot pengamatan, untuk setiap kedalaman tanah. Contoh tanah komposit ini terdiri dari contoh tanah terganggu (sekitar 1 kg tanah) dan contoh tanah tidak terganggu (4 ring sampel tanah). Analisis laboratorium terhadap karakteristik tanah meliputi kemantapan agregat tanah, kepadatan tanah, porositas tanah, konduktivitas hidrolik jenuh tanah, dan WHC (Water Holding Capacity). Hasil penelitian menunjukkan bahwa kemantapan agregat tanah pada kedalaman 20-80 cm di kebun kopi dengan umur pohon kopi yang berbeda mempunyai nilai yang berbeda-beda, tergolong dalam agregat tanah “Sangat Mantap”. Kemantapan agregat tanah mempunyai hubungan yang signifikan dengan beberapa sifat fisika tanah seperti berat isi, porositas tanah, kandungan fraksi pasir dan liat, serta WHC (Water Holding Capacity) tanah. Kemantapan agregat tanah, berat isi tanah, dan WHC tanah pada zona perakaran tanaman kopi (kedalaman tanah 20-80 cm) secara bersama-sama berpengaruh signifikan terhadap produktivitas tanaman kopi.

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.
