Fluktuasi Genangan Air dan Pemberian Campuran Kapur dan Kompos Jerami Padi: Pengaruhnya terhadap pH dan Fe Larut pada Tanah Sulfat Masam
Get PDFSwamps in Indonesia are widely spread over four major islands, namely in Sumatra, Kalimantan, Papua, and Sulawesi Papua. The problem with acid-sulfate soils is when the pyrite layer is oxidized. This study used a two-factorial with completly randomized design (CRD). The first factor was flooding fluctuation an the second factor was lime with straw compost. The soil parameters tested were pH and soluble Fe. Observations in the second week of the treatment of fluctuations in puddles that were drained, then flooded and added with a mixture of 3 t ha-1 lime, and 2.5 t ha-1 of straw compos resulted in the highest pH of 6.21. The best soil pH was given lime at 3 t ha-1, both flooded and drained. Observations in the fourth week produced the highest pH, namely 4.80. The pH value of the slightly acidic soil was due to an oxidation-reduction process. The 2nd week of observation had the highest soluble Fe value of 221 mg kg1, which was due to the analysis of soluble Fe using a pH of 4.8 so that Fe2+ increased in dissolved Fe. The fourth week of observation had the lowest soluble Fe value of 56.34 mg kg-1. This was due to flooding and the application of a mixture of lime and rice straw compost. The results of the study show that the interaction of fluctuations in water, lime, and rice straw compost that can affect soil pH and the solubility of soil soluble iron (Fe2+)
Karakteristik Kimia Tanah Gambut pada Tiga Tipe Penggunaan Lahan
Get PDFPeat soil is a soil that has been decomposed by organic matter. Man-made peatlands have been converted into agricultural land. In addition to being turned into agricultural land, some peatlands are also not used, causing the land to turn into shrubs and causing land to burn because it is not managed by the owner. Peatlands therefore consist of various types of land use. Peat soils in different types of land use have different characteristics. The purpose of the study was to determine the differences in some of the chemical properties of peatlands that have been used for shrubs, open land, and agriculture. To see the differences in soil chemical properties on various land uses, descriptive analysis, and standard deviation are used by presenting bar charts. The soil pH content on agricultural land is higher. The C-organic content in shrubs is higher than in agricultural land. Ash content on agricultural land is higher. Dissolved organic carbon on agricultural land tends to be lower.Peat soil is a soil that has been decomposed by organic matter. Man-made peatlands have been converted into agricultural land.

Pengaruh Abu Janjang Kosong Kelapa Sawit dengan Kompos Eceng Gondok terhadap Perubahan Sifat Kimia Tanah Lahan Pasang Surut
Get PDFMarshes that are affected either directly or indirectly by the ebb and flow of seawater are known as tidal wetlands. The lack of soil nutrients like low pH, N, P, and K, as well as the high solubility of Al and Fe, which can poison plants, is the problem with tidal wetlands. The goal of the study was. to find out how the application of oil palm empty fruit bunch (EFB) ash and water hyacinth compost changed the pH, organic C, N, P, and K levels of the soil in tidal wetlands. The randomized complete design (CRD) method was used in this pot experiment, with two factors: 1) four applications of oil palm EFB ash, and 2) four applications of water hyacinth compost. Oil palm EFB ash had doses of 0 ton.ha-1, 1 ton.ha-1, 1.5 ton.ha-1, and 2 ton.ha-1, while water hyacinth compost had doses of 0 ton.ha-1, 2 ton.ha-1, 3 ton.ha-1, and 4 ton.ha-1, respectively. 32 experimental units were created when 16 treatment combinations were replicated twice. After four weeks of incubation, the soil was submerged in water to a height of 5 cm. The application of oil palm EFB ash and compost made from water hyacinths had significant effects on pH, N-NO3ˉ, available P, and K, but not organic C or N-NH4+. The findings suggest that the application of water hyacinth compost and oil palm EFB ash can raise the pH, organic C, and levels of N, P, K in the soil.Marshes that are affected either directly or indirectly by the ebb and flow of seawater are known as tidal wetlands.

Pemberian Biochar Arang Kayu dan Tandan Kosong Sawit terhadap Gas N2O pada Tanah Gambut yang Ditumbuhi Kelapa Sawit
Get PDFPeatlands are developed for agricultural cultivation, such as oil palm. The agricultural sector contributes 13.5% of the total greenhouse gas (GHG) emissions. Emissions from this sector are generally in the form of N2O 46%, CH4 45%, and CO2 9%. Recently, the focus on the development of peatlands for this activity has been so great, especially in relation to emissions of nitrous oxide (N2O). The potential for peatland to be used as agricultural land must pay attention to environmental aspects such as the level of N2O emissions. This study aims to determine the effect of wood activated to empty palm oil fruit bunches on N2O emissions from peatlands oil palm. This study used an allocation block design. The factors studied were the distribution of wood charcoal and empty palm oil bunches at 6 levels, namely: wood charcoal + 0 kg of empty palm fruit bunches; wood charcoal 0.75 kg + 0.75 kg of empty palm fruit bunches, and 0.375 empty palm fruit bunches+0.375 kg of wood charcoal; empty palm fruit bunch charcoal 1.5 kg+wood charcoal 1.5 kg. N2O gas was analyzed using the closed chamber method and the soil was analyzed for soil pH and field water capacity. The treatment was repeated 3 times, resulting in 18 experimental units. The results showed that on day 0, the application of wood charcoal and empty palm oil bunches did not affect N2O emissions, but on the 15 and 45 days. The results showed that the treatment affected N2O emissions.Peatlands are developed for agricultural cultivation, such as oil palm.

One of the controls that can be used is control using antagonistic agents. Bacteria Bacillus sp. and Pseudomanas fluorescens is an antagonist agent contained in PGPR which has the ability to suppress disease growth, increase plant root uptake of several nutrients and increase plant growth. This study aims to determine the effect of Bacillus sp. and P. fluorescens from bamboo roots in suppressing bacterial wilt disease of R. solanacearus in tomatoes. Using a Completely Randomized Design Method (CRD) consisting of 3 treatments, each treatment consisted of 6 replications so that 18 experimental units were obtained in vivo. Observations were made by measuring plant height, number of fruit, fruit weight and intensity of disease attack. The results obtained in this study indicate that the administration of Bacillus sp. and P. fluorescens were able to control bacterial wilt disease caused by Ralstonia solanacearum bacteria in tomato plants.Penyakit layu bakteri yang disebabkan oleh Ralstonia solanacearum pada tanaman tomat dapat menurunkan kuantitas dan kualitas sehingga perlu dilakukannya pengendalian terhadap penyakit tersebut.
