Abstract

Ultisols have the potential to be developed as productive agricultural land, but need several efforts by means of organic matter and fertilizer applications. Biourine is a fermented liquid waste from cow urine. One of the commodities developed in Ultisol is spinach (Ipomoea reptans Poir). The study aims to determine the effect of treatments of six biourin concentrations on available nitrogen, soil pH, and growth plants of spinach on Ultisol soil. The single factor of completely randomized design (CRD) used as an experimental design consists of six treatments with four replications (24 experimental units). The results showed that biourine had no effect on increasing soil ammonium-N and had no effect on soil nitrate-N and soil pH. Biourin affects the increase in wet weight and dry weight of spinach plants. There is a relationship between soil NO3- and NH4+ levels with wet weight. Biourin concentration level of 2% is the best concentration to increase ammonium-N, wet weight and dry weight.

Abstract

Swamps 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+).

Abstract

Acid sulfate soils contain pyrite and when pyrite is oxidized it causes the soil pH to decrease. Application of agricultural lime CaCO3 is needed to raise soil pH. The grain size of lime greatly affects the fast, slow, and persistent increase in soil pH. This research method used a completely randomized design (CRD) with a single factor, namely the grain size of agricultural lime (18-35 mesh, 18-70 mesh, <18 mesh, 35-70 mesh, <35 mesh, <70 mesh). The treatment was repeated 4 times. The dose of lime given is based on the value of the bulk density of the soil and the sulfur of the soil solution. Observation of soil pH was carried out after an incubation period of 4 weeks using glass electrodes with various ratios of soil and water (1:2.5; 1:5; 1:7.5; 1:10). The results showed that the grain size of lime affects the increase in pH of acid sulfate soil in the soil-water ratio measurement method of 1:5 and 1:10, except for the measurement method 1:2.5 and 1:7.5. The smaller the lime size, the greater the increase in pH of acid sulfate soil. The largest increase in soil pH in the soil-water ratio measurement method was 1:10, for each grain size from the largest to the smallest: 18 - 35 mesh, 18 - 70 mesh, <18 mesh, 35 - 70 mesh, <35 mesh and <70 mesh, resulting in soil pH successively: pH 4.52; pH 4.58; pH 4.53; pH 4.60 ; pH 4.63 and pH 4.70.

Abstract

Acid sulfate soil has a layer of pyrite, when it is oxidized, can acidify the soil. The presence of pyrite in acid sulfate soils is very diverse and must be known. Not knowing the depth of pyrite can have fatal consequences, because layers of pyrite can be lifted to the surface due to tillage so that it oxidizes. This study aims to determine and map the distribution of pyrite depth, soil pH, and redox potential. Soil samples were determined with an exploratory descriptive method through land surveys and supported by laboratory analysis of pH, Eh and FeS2. The results showed that acidity of acid sulphate soil at all sample points was classified as very acid, Eh was classified as low reduction till oxidation. Based on the results of observations of pyrite depth, 3,492.15 ha (78.1%) was actual acid sulfate soil and 979.13 ha (21.9) was potential acid sulfate soil. So proper management is needed when turning over the soil so that the pyrite is not exposed, applying lime, organic material and regulating the water level so that the groundwater level is not below the depth of the pyrite

Abstract

The general obstacles in cultivating rubber and oil palm are soil acidity and limited availability of nutrients, especially N, P, and K. These nutrients play an important role in the growth of rubber and oil palm plants. Knowing the nutrient content is necessary to be able to determine the management that needs to be carried out. The objective of this study is to determine differences in the nutrient content of N, P, and K on various lands planted with rubber and oil palm plants. Soil sample analysis was conducted in the laboratory for available N, available P, and available K. To determine differences in land use for the elements N, P and K, data were analyzed using an unpaired two sample t test. The results showed differences in available K and available P levels between the two land types, while no differences were observed in N availability between the two land types. This variation may be caused by differences in land management practices.

Abstract

The slope is one of the important elements in topography that affects various natural processes and human activities. Slope position can lead to reduced soil fertility due to runoff. This research aims to analyze the comparison of water-stable aggregate on different slope positions which are divided into three, namely between upper slope, middle slope and lower slope. The research method used is descriptive comparative, which is carried out by deliberate sampling on sloping land planted with rubber plants with a depth of 0-20 cm and the same slope of 25-45% and then analyzed in the soil laboratory. Data were analyzed by t-test to determine the comparison of water-stable aggregate different slope positions. The results showed that water-stable aggregate values at different slope positions had significant differences. Water-stable aggregate values in the upper slope tend to be smaller than those in the middle slope and lower slope which are much larger. Slope position, organic-C content, and clay fraction affect water-stable aggregate values

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

Background: Swamps are ecologically important ecosystems in the biogeochemical cycle and are one of the targets of land conversion for food estate development. Objective: This study aims to examine the impact of the minipolder system on soil organic carbon (SOC) stocks in the Food Estate area of Sambang Lihumm Banjar Regency, South Kalimantan. Methods: Soil sampling was conducted using a purposive sampling method in natural swamp (control) and tukungan plots (maize cultivation). The soil samples consisting of intact and disturbed were collected, with parameters analyzed including soil moisture content (gravimetric method), bulk density (gravimetric method), and %C-organic (Walkley and Black method). Results: The result of study showed that conversion of swamp to dry land agriculture reduced soil moisture content, while bulk density increased from 0.78 gram/cm3 to 1.19 gram/cm3. Furthermore, SCO stocks averaged 35.00 ton/ha in natural swamp and 37.73 ton/ha in tukungan. Conclusions: The conclusion of study is that the increased bulk density and accumulation of topsoil in tukungan contributed to higher soil organic carbon (SOC) stocks.
