Abstract

The excessive drainage system on peat causes the peat to dry out, especially during the dry season. This condition triggers the occurrence of extensive and intensive land fires, which causes changes in the characteristics of peat soils. This study aimed to study the characteristics of peat soil consisting of several physical and chemical properties of peat on burned and unburned land in oil palm plantations in Pematang Raman Village, Kumpeh District, Muaro Jambi Regency. The research was carried out using a survey method. Observation block area was determined by purposive sampling based on adjacent land conditions (burned and unburned). Observation points were set on a grid that was perpendicular to the canal with a horizontal distance of 200 m from 1000 m block length and a vertical distance of 50 m from 300 m block width with an area of each block + 30 ha. The time interval between the fire incident and sampling was 17 months. Soil samples were taken at a depth of 0-20 cm and 20-40 cm. The results showed that the physical and chemical properties of burnt and unburned peat showed differences in the level of maturity, physical and chemical properties of the soil. Burnt peat soil had a faster weathering rate as indicated by the dominance of the sapric maturity level in the top layer (0-20 cm) and below the surface (20-40 cm). The bulk density, ash content, and pH of the burned peat soil were higher, while the C-organic content, total N, C/N, and water content were lower.Keywords: burned; chemical and physical properties; peat soils

Abstract

Indonesia is an agrarian country and requires the development of improvements in soil productivity. The decline in soil productivity for agriculture is currently caused by several factors, namely land conversion to a decrease in the quantity of ground water. The actual frequency pattern of irrigation water needs with the application of dielectric sensor technology is carried out in cultivation in order to create efficiency in the provision of irrigation water. This research was conducted using a single factor experimental method with repeated measurements on three types of land use, namely land without vegetation, soil with grass vegetation, and soil with tomato cultivation. Measurements were carried out using an automated application of soil moisture monitoring based on dielectric technology with two measuring periods. Each measuring period consists of two weeks or fourteen days. Soil sample analysis was carried out at the Bengkulu University soil laboratory. The results of the observations were analyzed using variance (ANOVA) on the 5% F test table, the BNT test was carried out at the 5% level on data that had a significant effect. The results showed that the frequency of giving irrigation water on the 1st day to the 14th day in the 2 observation periods on the Bera land was the most common compared to the use of grass vegetated land and the use of tomato cultivation land, which was 5 times in the 1st and 4th periods. times in the 2nd period with 14 days each. Provision of irrigation water will stop automatically when the dielectrometer shows the field capacity so that it can show the frequency of giving different water to each field.Key words : Dielectric; Frequency; Irrigation water

Abstract

Entisols are sandy soils with P and K in form still fresh and cannot be absorbed by plants, thereby affecting plant growth and production. Therefore, it is necessary to add rice husk biochar and arbuscular mycorrhizal fungi (AMF) to help provide nutrients to support the growth of sweet corn plants. The research was carried out from August to October 2020 in Beringin Raya Village, Bengkulu City with coordinates S03°45,434' E102°15,687'. The study used a completely randomized design (CRD) with two factors. The first factor was the dose of rice husk biochar: 0, 5, and 10 tons ha-1 ; and the second factor was the AMF dose of 0, 5, and 10 g of propagule. The total 27 units was obtained from nine treatment combinations that was repeated three times. Each experimental unit consisted of 2 sample plants so that there were 54 polybags. Soil parameters observations were soil pH, CEC, organic C, nutrient levels of N, P, K and P uptake. Phosphor uptake was calculated based on the total dry weight of plants x nutrient content of P. The variables observed in plants were plant height, root length, plant dry weight (roots and stems), ear length, cob diameter, cob weight. The result was no interaction between rice husk biochar and AMF on growth, P uptake, and yield of sweet corn. Application 10 tons ha-1 of rice husk biochar of biochar and inoculation of 10 g of plant propagule-1 gave the best results on growth, P uptake, and yield of sweet corn.Keywords: Biochar: Entisols, Mycorrhizal
