Abstract

Peat 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.

Abstract

One of the challenges of acid sulfate soil is the high Fe content in the soil, thus effective processing is needed to address its toxicity. The purpose of this study was to determine the changes in soil pH, Fe solubility, and organic-C from liquid fertilizer in acid sulfate soil in Danda Jaya Village, as well as to determine the relationship between soluble Fe and soil pH, organic-C and soil pH, and soluble-Fe. This research was structured using a descriptive method by comparing the application of liquid fertilizer with a control. The study was conducted in the Chemistry, Physics, and Biology Laboratory of the Soil Department, Faculty of Agriculture, Lambung Mangkurat University. The results of the study showed that the application of liquid fertilizer was able to increase pH and organic-C and decrease Fe solubility. Additionally, there was a correlation between soluble-Fe and pH with a coefficient of -0,95, a correlation between organic-C and pH with a coefficient of 0,91, and a correlation between organic-C and soluble-Fe with a coefficient of -0.89. Furthermore, the equation for the relationships was soil pH = -0.002 soluble-Fe + 5.958, Soil pH = 0.30 organic-C + 4,43, and soluble Fe = -154.92 organic-C + 830.15.

Abstract

Problems faced in tidal swamp land include low soil pH, low nutrient content, and high levels of Al and Fe. The aim of this research was to determine the effect of the combination of NPK fertilizer and Futura coal fertilizer on the availability of P and to determine the relationship between the solubility of Al and Fe, pH and organic C on the availability of P in tidal swamp land. This research was carried out at the Chemistry Laboratory, Soil Department, Faculty of Agriculture, Lambung Mangkurat University from October-December 2023 using a single factor in Randomized Block Design with five treatments and three replications to obtain 15 experimental units. The combination of NPK and Futura increased the availability of P, organic-C, and soil pH and reduced the solubility of Al and Fe. A relationship was found between Al and soil pH, C-organic and Al, C-organic and soil pH, organic-C and soluble-Fe, soluble-Fe and soil pH.

Abstract

Acid mineral soils in Indonesia mostly develop in wet tropical climates supported by high temperatures, so the weathering process runs faster than in dry climate areas. High rainfall causes intensive leaching, so basic cations are lost from the soil layer, and the soil has low base saturation. Some acid mineral soils in Indonesia are farmed under rainfed systems. This soil has a low nutrient availability status compared to irrigated rice fields, due to the lack of water availability, and is still dependent on rainfall. Eco-Enzyme (EE) contains several nutrients and microbes from fermentation that can increase soil fertility. This research aims to determine the effect of EE N nutrient availability and early rice growth in rainfed paddy fields. This study uses a Completely Randomized Design single factor, namely the total bacterial population in EE consisting of 5 treatments, namely K0= control; K1= 8,1 x 106 cells mL-1 in EE; K2= 1,2 x 107 cells mL-1 in EE; K3= 1,6 x 107 cells mL-1 in EE; and K4= 2 x 107 cells mL-1 in EE. Each treatment was repeated 4 times so that there were 20 experimental units. The results of the study show that the provision of the total bacterial population in EE 1,2 x 107 cells mL-1 can increase the pH to 5,38, N-NH4+ to 154,60 mg kg-1, and N-NO3- to 8,26 mg kg-1. Giving total bacteria in EE 1,6 x 107 cells mL-1 can increase the viability of non-symbiotic N2 fixing microbes.
