ALLOPHANIC VS. NON-ALLOPHANIC HORIZONS: COMPARATIVE ANALYSIS OF SOIL PROPERTIES IN KYUSHU'S VOLCANIC ASH SOIL
Yuki Tanaka, Kazuki Nakamura
Andosols, volcanic ash-derived soils, play a vital role in upland farming in Japan, with distinct categorization into allophanic and non-allophanic types. Allophanic Andosols, constituting 69.9% of the total Andosol land area in Japan, are prevalent in regions with significant Holocene tephra deposition. In contrast, non-allophanic Andosols, accounting for 30.1% of the total Andosol area, occur in areas with minor tephra deposition. Both categories exhibit distinctive characteristics such as a thick black A-horizon, high phosphate fixation, superior water retention, and low bulk density. Despite similarities in morphology, chemistry, and physical attributes, non-allophanic Andosols possess unique features due to the presence of...
ECONOMIC SHIFTS: EXPLORING LIVELIHOOD DIVERSIFICATION VIA NETS AND SEAWEED IN KWALE
Paul Kimani Mwangi, Grace Achieng Omondi
The coastal marine fishing communities of Kenya have historically relied on fishing as their primary source of income, supporting livelihoods for generations. However, recent declines in fish catches have raised concerns, attributed to various factors including mangrove degradation and destructive fishing practices. This study explores the importance of diversifying livelihoods within these fishing communities to enhance resilience and economic security. Household diversification, characterized by the pursuit of new income sources while maintaining existing ones, is considered vital for household economic stability. This diversification concept is particularly relevant in the context of natural resource governance and has implications for fisheries management...
ALTERING SOIL PROPERTIES: INFLUENCE OF SULFUR POWDER ON CHEMICAL AND PHYSICAL ASPECTS IN THE JORDAN VALLEY
Ahmed Ali Hassan, Fatima Mohamed Ibrahim
The Jordan Valley, a unique geographic region in Jordan, boasts exceptional agricultural potential due to its distinctive soil and environmental conditions. It plays a pivotal role in the country's food production, providing a wide range of agricultural products, including grains, vegetables, and fruits. Additionally, the Jordan Valley serves as a vital source of agricultural exports to international markets, contributing significantly to the nation's food security and economic growth. However, the Jordan Valley faces formidable challenges, primarily water scarcity and land management issues, which demand innovative solutions for sustainable agricultural development. This study delves into the utilization of modern irrigation techniques...
