Abstract

Red-yellow podzolic soils are generally acidic and have poor chemical properties, so tolerant plants such as oil palm plants are needed. This research was to determine the effect of differences in the age of oil palms on the chemical properties of the Sei Daun plantation soil. The research was conducted in December 2022 using the method of purposive sampling according to plant age. Samples were taken from 5 lands with oil palm ages 8 years, 14 years, 16 years, and 25 years, as well as land without plants, 5 points were determined from each land, and each point was separated into 3 depths, namely 0-20 cm, 20-50 cm, and 50-70 cm, the 5 points were composited according to depth, producing 3 samples per field. The results of the analysis of soil chemical properties show that increasing the age of oil palm causes soil pH, thereby reducing available P, total N, exchangeable K, and CEC of soil, but increasing soil organic C, also increasing Fe-NH4OAC, Mn-NH4OAC, exchangeable Al but still in low value. Increasing the age of oil palms can lower the soil pH, thereby reducing the availability of nutrients. Fertilizer doses can be adjusted according to the age of the plant because the older it is, the more nutrients the plant absorbs.

Abstract

The development in the city has caused urban areas to experience significant growth due to increased activity. One of the visible changes is the change in the use of vegetated land for built-up land. The research location is in a peri-urban area of Depok and Mlati subdistrict, Sleman Regency. This research analyzed land use conversion in 2015-2020 and modeled land change predictions for the next 20 years (2025-2045) using Artificial Neural Network - Cellular Automata (ANN-CA). The ANN method used multiple output neurons to determine the probability of land use transition. CA was used to model land use change by applying transition probabilities. The source of land use data came from extracting SPOT images, and then the modeling process used QGIS Desktop 2.18.11 on the MOLUSCE plugin. The results showed that the peri-urban area experienced a decrease in agricultural and livestock land by 152.62 ha (2.52%) while building land increased by 148.74 ha (2.46%). The 2025-2045 land use conversion prediction shows that the reduction in agricultural land, plantations, and livestock will continue, and the land area for buildings and roads will increase.

Abstract

Low nutrient availability and high soil bulk density are caused by the loss of fertile soil particles due to the kinetic energy of rain. Land management that does not apply conservation principles such as soil covering is one of the factors causing this to happen. This research was conducted to determine the impact of using plastic mulch as one of conservation actions. This research was conducted at the experimental field University of Siliwangi, Mugarsari. Soil samples were taken from mulched and without mulch lands as treatments. Soil samples were collected at 0-10 and 10-30 cm soil depths. Soil samples were taken to analyze the chemical properties of the soils (i.e., pH H2O, organic C, total N, available P, exchangeable K, Ca, Mg, Na) and physical properties (i.e., soil bulk density, porosity, water content, and texture). The results showed that the use of mulch had a significant effect (p<0.05) on pH H2O, organic C, total N, available P, exchangeable K, exchangeable Ca, bulk density, and water content. The results of the correlation showed that increasing organic C in mulched land had an effect on decreasing BD (r = -0.739). In addition, the organic C increased soil porosity (r = 0.612). Meanwhile, soil depth had no effect (p>0.05) on soil chemical and physical properties.

Abstract

Coffee plants (Coffea sp.) are among the most popular plantation crops for farmers in Wajak District. However, the soil condition in Wajak District is dominated by sandy soil, which can trigger soil sensitivity to high erosion potential. A mitigation effort for the declining of coffee production in the Wajak District can be made through the estimation of the soil erodibility index. This study aimed to suspect the soil erodibility index and obtain the relationship of soil erodibility index to coffee production on smallholder coffee plantations in Wajak District, Malang Regency. The methods of determining land boundaries with land map units (SPL) were land use, soil type, and slope. The parameters used were soil texture (M), organic matter (a), structure (b), and permeability (c) to determine erodibility, as well as coffee beans for coffee production analysis. Statistical analysis of data was in the form of correlation tests and data regression tests. The results of the data analysis showed that the highest wet weight of coffee fruit was found in SPL 8 with plantation land use, Typic Hapludands soil type and land slope of 8-15%. The wet weight value of coffee fruit at SPL 8 is 2.18 t ha-1 with an erodibility value of 0.37. While the lowest wet weight of coffee beans was found in SPL 2 with moor land use, Andic Eutrudepts soil type and land slope of 8-15%. The average wet weight value of coffee beans at SPL 2 was 0.12 t ha-1 with an erodibility value of 0.26.

Abstract

The conversion of rice fields in Seyegan is suspected to occur due to low soil fertility. This study was conducted to analyze the extent and distribution of conversion of rice fields associated with soil fertility status. This study used a survey method, purposive determination of sample points on rice fields representing the converted rice fields, and soil samples were taken compositely. Data analysis used spatial analysis, graphs, and laboratory tests. The parameters tested were cation exchange capacity (CEC), Base Saturation, potential P2O5, potential K2O, and organic C. Determination of soil fertility status was based on The Technical Guidelines For Soil Fertility Evaluation of Soil Research Center. The results showed that the area of rice fields in Seyegan District in 2015-2022 decreased by 55.26 ha (3.76%), with an average annual decrease of 7.89 ha. The soil fertility status in rice fields converted into settlements was very low to medium, rice fields into dryland and poultry farming were medium, and rice fields into shrubs and factories were low. The limiting factors of soil fertility were CEC and organic C.

Abstract

The difference in the productivity level of paddy is caused by nutrient availability and land management. This study aims to determine the chemical properties of soil, especially elements of N, P, and K, in soils that have different levels of rice productivity. The methods used in this study are survey methods and laboratory analysis. Purposive sampling was conducted based on the productivity of medium and high-status rice fields. Based on the level of productivity of rice fields, there are 18 sample points, which are composite into 7 samples and analyzed in the laboratory. The results showed that several chemical properties in areas with high productivity levels had an average availability of total N nutrient status of 0.17% (low), potential P 56.5 mg 100 g-1 (high), potential K 17 mg 100 g-1 (low), organic C by 2.75% (medium), cation exchange capacity (CEC) 11.52 cmol(+)kg-1 (low) while in areas with medium productivity had an average total N nutrient of 0.23% (medium), potential P 38.33 mg 100 g-1 (medium), potential  K 72 mg 100 g-1 (very high), organic C 3.23% (high), CEC 33.06 cmol(+)kg-1 (high) and has a soil pH of 6.1 (slightly acid) respectively. High-productivity areas have low to medium soil fertility, while medium-productivity areas have medium to high soil fertility. Rice field management factors are suspected to cause differences in rice productivity levels.

Abstract

Evaluation of land suitability was carried out in Kasihan District to determine the land suitability class for food plants. This research was conducted to determine the limiting factors that resulted in a decrease in soil fertility in the local area. Land suitability classes were obtained in S3, and N classes with limiting factors for water availability (wa), erosion hazard (eh), root media (rc), and nutrient retention (nr). The limiting factors that are found in the study area are the erosion hazard, soil pH, and organic C levels. Improvement efforts as an agricultural area development that can be done are making bunds to reduce slopes, giving biochar to increase organic C levels, and reducing soil pH. The limiting factors of soil texture and depth cannot be repaired. Soil texture is a property of the soil that is influenced by nature and is very difficult to change, and the depth of the soil cannot be changed unless other agricultural commodities are selected.

Abstract

Indonesia boasts a high biodiversity, intricately linked to the various ecosystems within its territories. In Majene Regency, West Sulawesi Province, for instance, there is a unique commodity in the form of pineapple, locally known as 'pondang'. One of the efforts to preserve this unique pineapple commodity is to understand the characteristics of the cultivation land that has sustained it over time. This research aimed to characterize the land in the cultivation areas of Majene's local pineapple as fundamental information for farmers to comprehend the plant growth ecosystem and manage the land optimally. The research utilized purposive random sampling based on the cultivation locations of Majene's local pineapple. Observations revealed that the cultivation land conditions for Majene's local pineapple had an average temperature ranging from 25.65 to 29.75 ºC, rainfall between 1,488.05 and 2,820.50 mm, with humidity ranging from 63.38 to 89.00%. Additionally, soil fertility conditions in the research locations indicated high nutrient retention, as shown by slightly acidic to neutral soil pH values and high Cation Exchange Capacity (CEC), although some available nutrients indicated very low to low soil fertility levels, such as potassium. Soil management significantly influenced nutrient availability, soil salinity, and alkalinity in the research locations.
