Abstract

Peatlands have the potential to serve as productive agricultural land but possess low soil quality, necessitating innovative technologies to enhance soil quality and crop productivity. The improvement of peat soil quality can be achieved by utilizing ameliorants such as Red Mud and cattle manure. This study aims to investigate the role of Red Mud and cattle manure on the availability of macronutrients and the growth of hybrid corn plants in peat soil. The research was designed using a completely randomized design (CRD) with treatments of Red Mud and cattle manure. The first factor was Red Mud treatment at four dosage levels: without Red Mud (L0), 7 tons/ha (L1), 14 tons/ha (L2), and 21 tons/ha (L3). The second factor was cattle manure with four dosage levels: without cattle manure (P0), 50 tons/ha (P1), 100 tons/ha (P2), and 150 tons/ha (P3). The experiment was repeated three times, resulting in 48 experimental units. The results showed that the interaction between Red Mud and cattle manure significantly affected the parameters of exchangeable sodium availability and stem diameter. The single treatment of Red Mud had a significant effect on the parameters of pH, exchangeable potassium (K-dd), exchangeable sodium (Na-dd), cation exchange capacity (CEC), and plant height, with the best dosage being 21 tons/ha of Red Mud. The single treatment of cattle manure had a significant effect on the parameters of total nitrogen (N-total), available phosphorus (P-available), exchangeable potassium (K-dd), exchangeable sodium (Na-dd), and plant height, with the best dosage being 150 tons/ha of cattle manure. Keyword : amandement, peat soil, produktivity, quality

Abstract

Lahan pasang surut adalah lahan yang dipengaruhi oleh pasang (naik) dan surutnya (turun) air laut atau sungai, lahan pasang surut termasuk salah satu tipe ekosistem lahan basah. Penelitian ini bertujuan untuk mengetahui status kesuburan tanah dari jarak saluran air yang berbeda pada sawah pasang surut di Desa Parit Keladi Kecamatan Sungai Kakap Kabupaten Kubu Raya. Penelitian ini dilakukan dengan metode survey di lapangan yang dilaksanakan pada lahan sawah pasang surut di Desa Parit Keladi Kecamatan Sungai Kakap Kabupaten Kubu Raya. Penelitian dilakukan dengan pengambilan 4 titik sampel dengan metode diagonal diambil pada 5 titik utama, masing-masing titik akan dikompositkan menjadi satu sampel. Sampel tanah kemudian dianalisis di laboratorium. Hasil penelitian menunjukkan Status kesuburan pada lokasi penelitian di sawah pasang surut dari ke-4 titik pengamatan tergolong dalam status kesuburan tanah rendah. Rendahnya kesuburan tanah disebabkan karena KB dan K-total tanah termasuk dalam kriteria rendah. Semakin jauh jarak dari saluran air menunjukkan adanya peningkatan dari KTK, KB dan P-total, sedangkan K-total dan C-organik menurun semakin jauh jaraknya.

Abstract

Oil Palm Plants (Elaeis guineensis Jacq.) are one type of plantation crop that occupies an important position in the agricultural sector in general, and the plantation sector in particular. Oil palm can grow in Ultisol soil which has a low fertility level. The characteristics of the elements in the soil greatly influence the characteristics of the elements in the plants that grow on it, so that the content of essential and non-essential elements that are deficient or excessive in plant tissue will reflect the content of the elements in the soil. The aim of this research is to analyze the nutrients magnesium, calcium and sodium as well as the soil base saturation of ultisol on oil palm land in Kelompu Village, Kembayan District, Sanggau Regency. The method used in this research is the survey method and soil sampling using the grid system method. The observation point represents a land area of 1,000 x 1,000 m or 10 ha. Soil samples or specimens are taken at a depth of 0-30 cm in a composite manner for the purpose of analyzing the chemical properties of the soil. Oil palm fields in Ultisol soil for all locations have almost the same soil chemical properties of magnesium, calcium and sodium, that is, they tend to have chemical properties that are classified as low class.

Abstract

Effect of Coated Urea with Humic-Calcium on Transformation of Nitrogen in Coastal Sandy Soil: A Soil Column Method (Sulakhudin, A  Syukur, D  Shiddieq and T  Yuwono):  In coastal sandy soil, mainly nitrogen losses due to leaching resulted to low fertilizer efficiency. Slow-release N fertilizers are proposed to minimize these losses, and humic-calcium coated urea has been examined. A soil column method was used to compare the effects of coated urea with humic-calcium on transformation and leaching loss of N in coastal sandy soil. The experiment aid to compare two kind source humic substances (cow manure and peat) which mixed with calcium as coated urea on transformation, vertical distribution and leaching N in coastal sandy soil. The concentration of humic-calcium coated urea i.e.1%, 5% and 10% based on their weight.  The results showed that urea coated with humic-calcium from cow manure (UCHM) and humic-calcium from peat (UCHP) increased the N total and available N in the soil and decreased leaching loss of N from the soil column. Compare to UCHP, UCHM in all concentration showed N-nitrate higher than N-ammonium on incubation length 2, 4 and 6 weeks. The N leached from a costal sandy soil with application coated urea with UCHM ranged from 21.18% to 23.72% of the total N added as fertilizer, for coated urea with UCHP they ranged between 21.44% and 23.25%, whereas for urea (control) reach 29.48%. Leaching losses of mineral N were lower when urea coated with UCHM compared to urea coated with UCHP or urea fertilizer.  The study concluded that the UCHM is better than UCHP in decreasing N leached from coastal sandy soil.

Abstract

Peat soil is acidic with an average pH below neutral. This is a challenge for farmers to utilize the vast amount of peat soil in West Kalimantan. Ameliorants used from materials that are easily available and can reduce dependence on the use of factory fertilizers. Husk charcoal is one of the organic materials that can increase nutrients and the combination of NPK fertilizer can increase shallot production. This study aims to see the effect of rice husk charcoal and NPK on planting shallot plants on peatlands. The research was conducted by planting 9 treatment samples on peat soil using a predetermined dose of rice husk charcoal and NPK fertilizer with 3 repetitions of each treatment. The research design used a complete factorial randomized design with the first factor being the dose of rice husk charcoal and the second factor being the dose of NPK fertilizer. From the results of this study, the largest dose of rice husk charcoal and NPK fertilizer is 700g/polybag of rice husk charcoal and 10g/polybag of NPK fertilizer is the most optimal dose for shallot plants grown in peat soil by increasing soil N-total, bulb weight, bulb diameter and bulb length of shallot plants.

Abstract

Tanah Ultisol merupakan satu diantara jenis tanah yang tersebar luas di Indonesia terutama Kalimantan Barat dan berpotensi untuk digunakan sebagai lahan budidaya tanaman jagung Hibrida. Berdasarkan karakteristiknya, Ultisol memiliki kendala apabila dijadikan lahan pertanian yaitu memiliki pH yang masam hingga sangat masam, unsur harayang rendah, KTK rendah, dan kejenuhan basa rendah. Upaya untuk mengatasi permasalahan tersebut yaitu dengan penambahan amilioran berupa red mud dan pukan sapi disertai dengan pupuk dasar NPK majamuk (10 g/polybag). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) untuk mengetahui pengaruh perlakuan terhadap analisis ANOVA dengan uji F. Apabila terdapat beda nyata antar perlakuan dilanjutkan dengan uji Duncan’s Multiple Range Test (DMRT) dengan taraf kepercayaan 5%. Penelitian ini terdiri dari 2 faktor. Faktor pertama yaitu red mud sebanyak 4 taraf R0 (Tanpa Perlakuan), R1 (100 gram/polybag), R2 (200 gram/polybag), R3 ( 300 gram/polybag) dan faktor kedua Pupuk Kandang Sapi sebanyak 3 taraf S0 (Tanpa Perlakuan), S1( 800 g/polybag), S2 ( 1.200 g/ polybag), sehingga total kombinasi perlakuan sebanyak 12 dan diulang 3 kali sehingga terdapat 36 unit percobaan. Hasil penelitian menunjukkan interaksi red mud dan pupuk kandang sapi berpengaruh nyata terhadap Ketersedian Salinitas, pH, Fosfor dan Daya Hantar Listrik. Pemberian red mud secara tunggal memberikan pengaruh pada paremter ketersedian pH, Fosfor, Daya Hantar Listrik, C-organik, Tinggi Tanaman dan Diameter Batang. Pemberian pupuk kandang Sapi secara tunggal memberikan pengaruh pada semua parameter.
