Abstract

Swampland in Indonesia covers an area of ​​34.93 million ha spread over various islands such as Sumatra, Java, Kalimantan, Sulawesi, and Papua. One type of swamp land that is often used in agriculture is tidal lands. The problems faced in the development of tidal lands for agriculture include acidic soil pH, high levels of soluble Fe and Al. One of the efforts to overcome the problem of acidic soil pH, high levels of soluble Fe and Al-dd is liming. The finer grain level of lime may increase the effectiveness of liming. The purpose of this study was to quantify the effect of lime grain sizes on changes in pH, dissolved Fe, and exchangeable Al of tidal lands. This study employed a one-factor completely randomized design (CRD) consisting of 6 treatments (Control; CaCO3 more than 1.00 mm (> 18 mesh); CaCO3 lime, 0.5-100 mm (18 -35mesh); CaCO3 measuring 0.21-0.50 mm (35-70 mesh); CaCO3 measuring 0.21 mm (<70 mesh); CaCO3 lime measuring 0.15-1.00 mm (18 -100 mesh)). The results showed that the difference in the size of the CaCO3 lime granules had a significant effect on changes in pH, soluble Fe and exchangeable Al. The application of CaCO3 lime granules 0.21 mm (<70 mesh) result in increases in soil pH and suppress soluble Fe and exchangeable Al.

Abstract

This study aims to determine the effect of swallow droppings and its best treatment on pH, CEC, organic-C, mineral-N, and available-P in Ultisols. The research method used was a one-factor Completely Randomized Design (CRD) with an incubation period of two weeks, with five treatments of 0, 2.5, 3.0, and 3.5 t ha-1 swallow droppings. Each treatment repeated four times to make 20 experimental units. Parameters observed were soil pH (H2O), CEC, organic-C, mineral-N, and available-P. The results showed that the application of swallow droppings affected pH, CEC, organic-C, mineral-N, and available-P in Ultisols. Swallow droppings of 3.5 t ha-1 significantly affected mineral-N (N-NH4+ and N-NO3-) and other parameters such as CEC, available-P, pH, and organic-C.

Abstract

The distribution area of mineral soil in Indonesia reaches 148 million ha. The acid mineral soil in South Kalimantan for Ultisol reaches 886.186 ha. Ultisols have low fertility and P availability. The low availability of P in the soil is caused by P being absorbed. Isothermal absorption is very useful for measuring P adsorption in the soil due to strong P fixation by Fe and Al in Ultisol soils. Many researchers have suggested determining the amount of P required to reach an optimum level for maximum crop yield to quantitatively describe isothermal adsorption, the most popular of which are Langmuir, Freundlich, and the Brunauer-Emmett-Teller (BET) equations. The purpose of this study was to determine the isothermal adsorption limit of P and describe quantitatively the isothermal adsorption in Ultisols in Banjarbaru City using the Langmuir, Freundlich, and BET equations. From the research results, it can be concluded that P adsorption on Ultisols in Gunung Kupang Village, Cempaka District, Banjarbaru City follows the BET Equation. The high and low P adsorption indicated the availability of P. In other words, the fixation activity of acid mineral soils could result in a smaller amount of available P for plants.

Abstract

Wetlands have unique biodiversity and natural phenomena. The climate has recently changed rapidly due to greenhouse gas emissions, especially nitrous oxide from human activities such as paddy rice farming. The purpose of this study is to determine the effect of rice field waste management on the population of nitrogen-fixing bacteria and N2O emissions, and as to determine the shape and closeness of the relationship between the population of nitrogen-fixing bacteria and N2O emissions with different waste management methods. The research method used is a one-factor RGD. Close chamber technique is used for N2O emmisions analysis. The factor tested was the method of managing paddy waste before rice planting with five treatments, namely: A = Rice field waste was slashed and then lifted into the mound after a few days of being returned to the field; B = Rice field waste is carried out management slashed, rolled up, reversed and stretched; C = Rice field waste is slashed, planted with traces and then slashed again after the trace is transferred to land outside the research plot; D = Rice field waste sprayed with herbicide 2 times; E = Rice field waste sprayed with herbicide 1 time and then soil in the tractor. Each treatment was repeated four times so that 20 units of the experiment were obtained. The results showed that the method of rice field waste management carried out had no real effect on N2O emissions and nitrogen-fixing bacteria. N2O emissions not correlate with the activity of nitrogen-fixing bacteria from several methods of rice field waste management carried out

Abstract

Peat swamp land in Indonesia is quite extensive, which is 10.8% of Indonesia's land area, the area of peatland in Indonesia is estimated at around 14.95 million hectares, the largest on the islands of Sumatra, Kalimantan and Papua and a small part in Sulawesi. The dry process is not good can be associated with bulk density. Irreversible dryness can occur in peat with low lindak density, while peat with high lindak density is relatively easy to reabsorb water. Peat soils store much higher carbon than mineral soils. Every gr of dry peat stores about 180-600 mg of carbon, while every gr of mineral soil contains only 5-80 mg of carbon. This research method uses a descriptive exploratory method whose variable approach is carried out through land surveys and is supported by the results of soil analysis in the laboratory. The results showed the value of water content and water absorption of peat soil in the protected forest of Banjarbaru peat soil based on different times and showed a decrease in the level and absorption of peat soil.

Abstract

Organic matter application and water management were frequently applied to prevent the oxidation of pyrite in acid sulfate soils. The purpose of this study was to determine the effect of cow manure application with varying height of inundation on soil pH, soluble-Fe, and available P of acid sulfate soils. This study employed factorial treatments and in a completely randomized design. The first factor was the dosage of cow manure: 0, 10, and 20 t ha-1, while the second factor was various water depths: 5, 10, and 15 cm. Results of study showed that the interaction of cow manure and water depth did not affect soil pH, but single factor of the treatments (cow manure and water depth) significantly affected soil pH. The interaction of cow manure and water depths did not significantly decrease the solubel-Fe in the fourth week. The interaction of cow manure and water depths significantly increased P-availability in the fourth week. Results of this study demonstrated that cow manure application and water depth improved soil pH and P-availability of acid sulfate soils.

Abstract

One of the prospective places for agricultural usage in acid sulfate rice fields, which are typically spread out in lowland areas along coastlines that occasionally undergo flooding. If handled effectively in accordance with the issues found in the land, this site can be developed as a productive agricultural region. Agricultural development on acid sulfate soils frequently encounters a number of issues, including (pH) acidic soil, high iron content, a lack of phosphate availability, and the presence of pyrite (FeS2). In this study, the relationship between P availability, Fe solubility, the Fe-P fraction, pH, Eh, and pyrite depth in acid sulfate paddy fields will be examined. Purposive sampling was used in field research utilizing the survey method in the acid sulphate rice fields of Barito Kuala Regency. This research was based on the distribution map of Fe solubility in Barito Kuala Regency. The results of this study indicate that there are three variables that have a significant effect on P availability: soluble Fe amd Fe-P fraction with the power regression form and a very strong relationship; and soil pH with a linear regression form and a strong relationship. Pyrite depth and soil Eh had no significant relationship with P availability in acid-sulfate lowland rice fields.
