Abstract

Podsolic soil in South Kalimantan has a low fertility rate including pH, organic matter, cation exchange capacity (CEC), solubility P, and has a high solubility of aluminum (Al) and iron (Fe). It causes fixation P by Al and Fe in the form of Al-P and Fe-P, which makes P difficult to dissolve in the soil. Zeolite is an ameliorant that is capable of improving soil chemical properties based on its ability to carry out ion exchange, adsorption, absorb molecules, increase fertilizer efficiency, increase soil CEC, and the availability of Ca, K, and P ions, which can reduce aluminum content. The purpose of this study was to identify the pattern of relationships caused by application of activated natural zeolite on Podsolic soil against pH, CEC, available P, soluble Fe, and exchangeable Al. This study was a pot experiment weighing 0.5 kg of soil, carried out in a greenhouse and arranged using CRD a single factor . The incubation period was carried out for eight weeks with three replications. The results showed that there was a relationship between the zeolite dose activated against the available P (the linear regression equation Y = 0.6 + 0.032 X, R2 = 0.4969, and r = 0.7006*), while the doses of zeolite had no significant effect on pH, CEC, soluble Fe, and exchangeable Al.

Abstract

Endopedon identification is very necessary to determine the development, physical and chemical properties of soil. The development of endopedons originating from ultramafic rocks around Kiram Village, Karang Intan District, Banjar Regency has not been studied much, therefore it is necessary to explore more about the results of soil development. This research was a descriptive method to identify diagnostic horizons that develop in the endopedon. South Kalimantan is one of the areas where ultrabasic rocks are distributed and is an area with a wet tropical climate. The weathering force of the parent material will be faster in the wet tropics. Ultrabasic rocks in each region have different mineral and chemical compositions. Based on the research results, the Oxic horizon in Profile-1 was found at a depth of 29 cm to 76 cm from the ground surface. While in Profile-2 the Oxic horizon was found at a depth of 19 cm to 110 cm from the ground surface. The formation of the oxic horizon is due to the Latosolization process. Such as the long laterization process is supported by environmental conditions, climate, and rainfall making this laterization process will be better.

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

Although ultramafic rocks are widespread in Indonesia and have the potential to influence soil properties, studies on the genesis and properties of soils formed from these rocks, especially to understand the characteristics of the lower defining horizon or endopedon, are still limited. This study aims to identify the endopedons formed, which developed from the ultrabasic rocks. This research is descriptive, soil profile points are determined by purposive sampling method by considering that points are true ultrabasic rock distribution. Observations made in this study include observations in the field and observations in the laboratory. The data from the description and laboratory analysis were used as reference for identifying endopedon. Endopedon determination refers to the Keys to Soil Taxonomy 2014 , the twelfth edition. The oxic horizon in Profile-1 is found at a depth of 7 cm to 37 cm from the soil surface with the horizon codes Bo. The Oxic horizon in Profile-2 is located at a depth of 20 cm to 106 cm from the soil surface with the horizon codes Bo1, Bo2. Latosolization is the process that causes the formation of the oxic horizon. The study site is also an area with a wet tropical climate that supports the formation of the oxic horizon.
