Abstract

Water and nutrients is important for plant which has its characteristics. This study has been carried out in the UB (Brawijaya University) forest about soil moisture content during rainy and dry seasons, Total-N, -P, -K from litter on different types of shade and age of coffee plants, and their effect on soil Available-N, -P, and -K. There are P1 (control), P2 (4-year-coffee + pine), P3 (7-year-coffee + pine), P4 (4-year-coffee + mahogany), and P5 (7-year-coffee + mahogany). These treatments affected to total soil moisture storage, Total-N, -P, -K of litter, and Available-N, -P, -K in the soil. The soil moisture storage change between rainy and dry seasons was 36.97 mm. The highest Total-N, -P, and -K of litter was 11.00 kg ha-1 y-1 at P3, 1.06 kg ha-1 y-1 at P2, and 4.35 kg ha-1 y-1 at P3, which was inconsistently associated with high soil nutrients. The highest Total-N was 0.40 (0-20 cm), 0.27 (20-40 cm), 0.30% (40-60 cm) at P4, Available-K was 1.69 (0-20 cm), 1.64 (20-40 cm), 1.87 cmol kg-1 (40-60 cm) at P5, and Available-P was 15.21 (0-20 cm), 14.06 (20-40 cm), 12.64 mg kg-1 (40-60 cm) at P1.

Abstract

The Upper Konto Watershed in Malang Regency is an area with various types of land use that have the potential to influence soil physical properties and soil water retention. Soil water retention is the ability of soil to absorb and retain water, which is closely related to the availability of water that plants can utilize. One of the soil types that dominate this region is inceptisol, which can face constraints in water retention, mainly when land use changes or inappropriate management practices occur. This study aims to analyze the impact of different types of land use on soil water retention characteristics in the Inceptisols of the Upper Konto watershed. The research method was conducted through field surveys and laboratory analysis. A survey was conducted on 16 Land Map Units (LMUs) derived from the overlay of land use, soil type, and slope maps. A total of 64 soil samples were collected for laboratory analysis. The observed variables included soil texture, bulk density, particle density, soil porosity, soil aggregate stability, soil organic matter, and soil water retention at pF 0, 2.5, and 4.2. The results revealed that land use types have a significant influence on soil physical properties as well as water retention characteristics. Specifically, it was found that forest land with the Udic Eutrandepts soil type had the highest water retention capability (0.39 cm3 cm-3). In comparison, dry farmland with the same soil type had the lowest water retention capability (0.06 cm3 cm-3). These findings illustrate the stark differences in the ability of soils to retain water between different land use types.

Abstract

The eruption of Mount Semeru in East Java released pyroclastic materials that damaged agroecosystems and degraded the soil physical properties. Pyroclastic materials tend to form surface crusts, leading to compaction and decreased permeability, which hinders soil recovery. To accelerate rehabilitation, adaptive vegetation and indigenous microbes were introduced to improve the physical properties of pyroclastic materials. This study aimed to assess the incorporation of indigenous microbes and adaptive vegetation in improving soil quality after an eruption. This study employed a factorial randomized complete block design with two factors: vegetation type, i.e., Napier grass (Vn), Centrosema sp. (Vc), and Indigofera sp. (Vi); and microbial application, i.e., without microbes (M0) and with indigenous microbes (M1). Soil bulk density, total porosity, permeability, available water content, and evapotranspiration were measured. The data were analyzed using ANOVA and LSD at 5% significance level, followed by regression and correlation analysis. The results showed that incorporating indigenous microbes with adaptive vegetation significantly increased total porosity, permeability, and available water content while decreasing bulk density and evapotranspiration. Specifically, the Napier grass with microbe treatment (VnM1) was most effective in reducing compaction, attributed to its extensive root system and enhanced microbial activity. This treatment improved water retention and provided a sustainable solution for rehabilitating pyroclastic materials, supporting long-term agricultural recovery after the eruption.

Abstract

With increasing concerns regarding water resource management and environmental sustainability, understanding land use change and the hydrological health of watersheds is critical for informed decision-making. This study aimed to explore the effect of land use changes on hydrological health resilience in the Rejoso watershed, East Java, using remote sensing techniques and geographic information system tools to characterize the various land cover types. Landsat ETM 7+ satellite imagery was used to describe land cover classes. Hydrological health indicators such as water transmission, water availability during the dry season, and peak rainfall buffer events were systematically analyzed in relation to land cover change conditions. Regression statistical methods were used to measure the impact of land cover changes on hydrological parameters. The study results showed that the area of forest land in the Rejoso watershed tended to increase from 2011 to 2021; on the other hand, the area of agroforestry land tended to decrease along with the increase in upland land. In general, the hydrological health of the Rejoso watershed is decreasing from year to year. The increase in forest area, agroforestry, settlements, and ponds provides a positive response to the hydrological health of the watershed. On the other hand, the increase in moorland and rice fields has a negative impact on the hydrological health of the watershed.

Abstract

High-traffic highway crossing agricultural fields impacts the quality of food crops grown on Vertisol agricultural fields in Pasuruan. Lead (Pb) released from the exhaust of motor vehicles into the air can eventually enter the soil and be absorbed by plants. This study aimed to examine the effect of Pb from exhaust motor vehicles emission on the Pb status and its behavior in soil, water, and plants. The study was initiated by conducting a survey to determine the sampling locations in selected inundated paddy and maize cropping systems. A stratified random sampling method was used to collect soil, water, and plant samples. The soil of the study area is dominated by Vertisol, with clay content ranging from 54% to 76%. The soil attributes a high cation exchange capacity ranging from 80.53 meq 100 g-1 to 93.57 meq 100 g-1. Pb emitted from 2,913,000 vehicles within four months period that entered the agricultural field was not absorbed by paddy and maize crops. Pb entered the soil in the adsorbed form, and no Pb was observed in the soluble form, so it was not absorbed by the roots. In the paddy field, the total Pb of 84.33% was influenced by pollutant distance. Likewise, in the maize field, 83.18% of total Pb was influenced by pollutant distance. The far the pollutant distance from the agricultural field, the lower its total Pb. Paddy field water is adsorbed onto the colloidal clay, which is dispersed due to inundation and sloughing of the paddy, moving with the clay and then dissolved in the water flow.
