Abstract

Peat soils contain high concentrations of organic nitrogen, but in a form that is not available to plants. South Kalimantan has NH4+ in the range 4.51- 736.86 mg.kg-1 and NO3- content is in the range of 0.37-54.69 mg.kg-1. The low availability of N nutrients in peatlands is due to the slow nitrogen mineralization process and the very high mobility of N in the soil. This study aims to determine the effect of the composition of peat and chicken manure on nitrogen mineralization. This study used a single factor in completely randomized design (CRD) with 5 treatments and 4 replications. carried out in greenhouses and in the Soil Laboratory of the Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The treatment is the composition of peat and chicken manure, namely 100% peat material, 80% peat material + 20% chicken manure, 60% peat material + 40% chicken manure, 40% peat material + 60% chicken manure, 20% peat material + 80% chicken manure. The best composition for nitrogen mineralization is based on the high nitrate content, which is found in the composition of 80% peat soil + 20% chicken manure in the first month of incubation, and on the composition of 80% peat soil + 20% chicken manure in the second month. This composition is the best composition from a combination of peat material and chicken manure against nitrogen mineralization in the form of nitrates.

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.

Abstract

Podzolic soils have various problems including acidity of the soil (pH) and low soil nutrient content. This study aims to determine the effect of guano and dolomite on the availability of P nutrients in podsolik soils, and to determine the best treatment. This study was a pot experiment using a completely randomized design (CRD) with one factor, namely (P1 = Dolomite 2 t ha-1); (P2 = Guano Fertilizer 0,5 t ha-1); (P3 Guano Fertilizer 0.5 t ha-1 and Dolomite 2 t ha-1); (P4 = Guano Fertilizer 1 t ha-1 and Dolomite 2 t ha-1); (P5 Guano Fertilizer 1.5 t ha-1 and Dolomite 2 t ha-1). Each treatment was repeated 4 times, so there were 24 experimental units. The results showed that the application of dolomite and guano fertilizers had an effect on the available-P, pH, Exchangable Ca and Exchangable Al. However, it has no effect on Mg-dd in Podzolic soil. The application of dolomite and guano fertilizer with a dosage of 0.5 t ha-1 guano fertilizer and 2 t ha-1 dolomite was the best result for the availability of P, Exchangable Ca and pH.

Abstract

Supporting the increase in agricultural production today cannot be separated from the use of herbicides in land preparation activities. Most of the herbicides applied to plants will eventually fall to the ground, then undergo changes and in a certain time will be absorbed by the clay fraction and organic matter in the soil, which is generally known as herbicide residue. Toxic herbicide residues in the soil can kill soil microbes, which are not actually the target (non-target microorganisms) so that they interfere with the activity of soil microorganisms which in turn can affect the nutrient cycle in the soil.This research was conducted with the aim of knowing the effect of giving herbicides with various types of active ingredients in paddy fields on the viability of N-fixing bacteria and their relationship to soil chemical properties.The research and analysis was carried out from November 2021 to January 2022. The method used in this study was the Completely Randomized Design (CRD) environmental design method with a single factor treatment design, namely the type of herbicide active ingredient. Based on the results of research that has been carried out, it is known that the herbicide Glyphosate can increase the population of atmospheric N2-fixing bacteria in the soil, while the herbicide Paraquat and Methyl Metsulfuron can suppress the population growth of atmospheric N2-fixing bacteria

Abstract

Ultisol is soil on acidic dry land which has problems such as low organic matter content, soil pH and availability of nutrients, one of which is P-available. Chicken manure and coal ash can function as ameliorant materials so that they can improve fertility in ultisol soil. This research aims to determine the effect of applying ameliorant (chicken manure and coal ash) on the acidity and P availability of ultisol soil. This research used a single factor Completely Randomized Design method with six treatments repeated four times to produce 24 experimental units including PA0 = control, PA1= 100% coal ash (0,25 t ha-1) + 0% chicken manure (0 t ha-1), PA2= 25% chicken manure (0,5 t ha-1) + 75% coal ash (0,75 t ha-1), PA3= 50% chicken manure (1 t ha-1) + 50% coal ash (0,50 t ha-1), PA4= 75% chicken manure (1,5 t ha-1) + 25% coal ash (0,25 t ha-1), PA5= 100% chicken manure (2 t ha-1) + 0% coal ash (0 t ha-1). Providing ameliorants in the form of chicken manure and coal ash can expand soil pH, available P and Ca-dd, can reduce soil Al-dd but cannot expand soil Mg-dd.
