Abstract

The potential of soil microbes as biofertilizer agents to enhance soil fertility and crop productivity has garnered increasing attention in recent years. This study investigates the role of various soil microorganisms, including bacteria, fungi, and actinomycetes, in promoting plant growth and improving soil health. By examining the mechanisms through which these microbes contribute to nutrient cycling, nitrogen fixation, and phytohormone production, we aim to understand their impact on crop yields and soil properties. Field trials conducted in diverse agricultural settings demonstrate that the application of microbial biofertilizers can lead to significant improvements in crop productivity and soil fertility. The findings suggest that incorporating soil microbes into sustainable agricultural practices could be a viable strategy to reduce dependency on chemical fertilizers and enhance long-term soil health

Abstract

Natural controls, such as predators and parasitoids, play a crucial role in maintaining the stability of agricultural ecosystems through biological pest control mechanisms. On the rice agriculture systems, we propose to evaluate the diversity and abundance of natural controls in organic and conventional rice cultivation systems in Tegal Sari Village, Ogan Komering Ulu Timur Regency, South Sumatra. Observations were conducted using a systematic survey method employing various types of insect traps, with organism identification carried out to the level of type. This research is expected to contribute to both academic and practical domains. The results revealed the presence of 10 arthropod species from four orders, including Araneae, with dominant species such as Pardosa pseudoannulata, Tetragnatha extensa, Tetragnatha montana, Tetragnatha sp., Tigrosa annexa, and Zygiella are always higher on the organic rice agricultural system compared to the conventional system. The diversity analysis indicated that sweep nets were more effective in capturing natural controls compared to other traps, with a Shannon-Wiener diversity index value of 2.17, suggesting moderate diversity. These findings emphasize that organic farming supports biodiversity conservation and provides a scientific foundation for the development of pest management strategies.
