Abstract

The mustard plant is a commercially valuable vegetable popular with the public, so demand for this vegetable continues to increase. One of the factors that influences growth in terms of external factors is the planting medium. Planting media made from organic materials is a solution to using chemicals that cause residues that damage the environment. This research was conducted to determine the best type of planting media and the composition of the planting media for the growth of kale plants. Treatment using P1 (Control) = soil; P2 = soil: organic fertilizer (goat manure) (1:1); P3 = soil: bamboo leaves (1:1) using Randomized Complete Block Design method with five replications. The research results on planting media treatment with goat manure influenced the growth of mustard greens, including plant height, number of leaves, leaf length, root length, and root wet weight.

Abstract

Fertilizer application, especially nitrogen (N), can have a negative impact on the soil and environment. This can be minimized by reducing fertilizer use with the utilization of functional microbes, namely nitrifying bacteria Nitrosomonas sp. and Nitrobacter sp. This study aims to examine the abundance of nitrifier bacteria in the rhizosphere of cereals and legumes. The stages of the study include taking isolate sources and isolating the total bacteria of Nitrosomonas sp. and Nitrobacter sp. The method of taking isolate sources in the rhizosphere of cereals and legumes with a depth of 20 cm. The results showed that the abundance of bacteria differed in various isolate sources. The abundance of Nitrosomonas sp. in isolate sources in the rhizosphere of legumes was higher than in the rhizosphere of cereals. The abundance of Nitrobacter sp. in isolate sources in the rhizosphere of cereals was higher than in the rhizosphere of legumes. Dry land has a relatively higher abundance of soil microbes compared to rice fields. The characteristics of the source land of the isolates and the rhizosphere affect the total abundance of Nitrosomonas sp.and Nitrobacter sp. The soil characteristics of the isolates source and the rhizosphere of different plants affected the total abundance of Nitrosomonas sp. and Nitrobacter sp.

Abstract

Soil degradation is a major constraint to agricultural sustainability, particularly in areas characterised by diverse environmental conditions. Halong District, Balangan Regency, South Kalimantan Province, is characterised by heterogeneous land uses, soil types, slope variations, and variable rainfall patterns, which influence soil quality and degradation risks. This research aims to assess the potential for soil degradation concerning environmental diversity and its implications for sustainable integrated agriculture. The study highlights that differences in land use, from shifting cultivation to permanent farming, combined with acidic soils, steep slopes, and uneven rainfall distribution, increase vulnerability to erosion, nutrient depletion, and declining soil fertility. The results show that the Potential Soil Degradation Risk (PSDR) in the low-risk class (PSDR.II) covers 298.22 km2 (45.20%), followed by the intermediate-risk (PSDR.III) covering 335.15 km2 (50.79%), and the high-risk (PSDR.IV) covering 26.48 km2 (4.01%). Land use and slope are determining factors for PSDR, as indicated by ANOVA, DMRT, and correlation test results. Understanding these linkages is essential for designing site-specific land management practices that reduce degradation risks while improving agricultural productivity. The outcomes of this research are expected to provide scientific recommendations for stakeholders in developing sustainable agricultural management strategies, such as soil conservation, organic matter management, and integrated crop-livestock systems, to mitigate degradation risks and support long-term agricultural resilience in Halong District.
