Abstract

The development and utilization of peat soil as a plant growing medium cannot be separated from limiting factors, one of which is the chemical properties of peat, namely low pH, very high cation exchange capacity (CEC) with very low base saturation (KB), and low macro and micro nutrients, resulting in low soil fertility and inhibited nutrients for plants. The provision of ameliorant in the form of sea mud is one alternative to improve the chemical properties of peat. The use of sea mud as a soil conditioner can improve the chemical properties of peat considering its high base content such as Calcium (Ca), Magnesium (Mg), Sodium (Na) and Potassium (K) cations. The high base content in sea mud can improve nutrient availability, low pH availability, can increase base saturation and reduce the high cation exchange capacity in peat soil. Improvement of peat soil characteristics with the addition of sea mud ameliorant can affect peat soil fertility. The purpose of this study was to study and analyze the role of sea mud in improving the chemical properties of peat. This study uses descriptive analysis by testing laboratory data of liquid sea mud. The parameters used in this study are soil pH, base saturation, cation exchange capacity, Sodium, Calcium, Potassium and Magnesium. The provision of sea mud on peat soil is given at a level of 5% and 7.5% on 10 kg of peat soil. The use of sea mud at a level of 7.5% gives better results in terms of decreasing the value of cation exchange capacity, increasing pH, increasing base saturation, increasing sodium, potassium, calcium and magnesium elements. Initial analysis of initial soil pH ranges from 3.37, KB 7.74% and CEC 119.66 cmol (+) kg-1, Sodium content 0.6 cmol (+) kg-1, calcium 5.37 cmol (+) kg-1, potassium 0.37 cmol (+) kg-1, and Magnesium 2.87 cmol (+) kg-1. But after the treatment of 7.5% sea mud there was an increase in pH to 3.54, KB 17.49% and CEC 112.29 cmol (+) kg-1, Magnesium 10.72 cmol (+) kg-1, Calcium 7.20 cmol (+) kg-1, and Sodium 0.66 cmol (+) kg1. The results of the study showed that the provision of sea mud on peat soil can improve the chemical properties of peat, especially the provision of sea mud at a level of 7.5%. This proves that the use of sea mud has great potential in improving the limiting factors found in peat soil.

Abstract

The objective of the study is to test the chemical content of alluvial soil with the application of manure. Alluvial soil has poor physical and chemical soil properties, including low pH, nutrients, C-organic soil cation exchange capacity and a low C/N ratio. Therefore, it requires action to improve the planting by adding manure ameliorant. This research was carried out from February 5th, 2023, to April 5th, 2023 in Sambas Regency, Sambas District. This research uses a descriptive analysis model by comparing laboratory analyses using samples before and after the incubation process for 30 days. The treatments referred to in this research are: chicken manure, cow manure and goat manure. The dose of alluvial soil and manure used is 1:1. The parameters used in the research include soil pH, soil CEC, organic carbon (C), C/N ratio, elements nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). The results of the research showed that there were changes in the chemical properties of the soil after being treated using chicken manure, cow manure and goat manure when compared to the untreated soil. The use of chicken manure on alluvial soil has a more beneficial effect on changes in soil pH values, soil CEC, C-organics, C/N ratio, N, P, K, Ca, and Mg elements when compared with the use of cow manure.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan bahan organik terhadap hasil empat varietas ubi jalar lokal serta interaksinya antara keduanya. Penelitian ini dilaksanakan pada tanggal 2 Februari 2014 sampai tanggal 2 Mei 2014 di kebun percobaan yang terletak di Desa Parit Lintang Kecamatan Salatiga. Waktu penelitian selama 3 bulan. Penelitian ini menggunakan metode eksperimen lapangan dan Rancangan Petak Terbagi (RPT) yang terdiri dari 2 faktor perlakuan dan 3 ulangan. Faktor 1 yaitu jenis varietas ubi jalar lokal yang ditempatkan sebagai mainplot terdiri dari ubi jalar oranye ( v1), ubi jalar kuning ( v2), ubi jalar putih ( v3), ubi jalar ungu ( v4). Faktor 2 sebagai subplot yaitu jenis bahan organik terdiri dari pupuk kotoran ayam (b1), pupuk kotoran sapi (b2), pupuk kotoran kambing (b3). Dosis penggunaan bahan organik yaitu pupuk kotoran ayam 30,30 kg/petak, pupuk kotoran sapi 15,31 kg/ petak, pupuk kotoran kambing 14 kg/petak. Setiap perlakuan terdiri dari 3 tanaman sampel. Variabel yang diamati dalam penelitian ini meliputi jumlah umbi pertanaman, jumlah umbi perpetak, berat umbi pertanaman (g), berat umbi perpetak (g), diameter umbi pertanaman (cm). Hasil penelitian menunjukan pemberian bahan organik dan penggunan varietas ubi jalar dapat meningkatkan hasil tanaman ubi jalar pada tanah alluvial. Pemberian bahan organik pupuk kotoran ayam dengan dosis 30,30 kg/petak merupakan perlakuan terbaik yang memberikan pengaruh yang lebih baik terhadap berat umbi perpetak, diameter umbi pertanaman, sedangkan perlakuan penggunaan varietas ubi jalar ungu dan putih merupakan varietas yang terbaik terhadap variabel jumlah umbi pertanaman.
