Biogeochemical cycling of zinc in soil-cassava cropping system in Thailand
Inadequate management in continuous plant production may deplete zinc (Zn) in soils, leading to Zn deficiency in staple foods and human malnutrition in underdeveloped countries. This study assessed Zn dynamics in cassava-grown soils in Thailand, revealing low available Zn levels and varied total Zn stocks. Phyllosilicates, organic matter, and iron oxyhydroxides were primary Zn hosts. Most locations experienced net Zn depletion, emphasizing the urgent need for Zn fertilizer and organic manure to sustain long-term crop production.

Effect of Long-Term Cassava Cultivation on the Morphology and Properties of Soils in Lampung, Southern Sumatra, Indonesia
The study investigates the impact of long-term cassava cultivation (> 20 years) on soil morphology and properties in Lampung, South Sumatra, Indonesia, compared to rarely tilled mixed gardens. Cassava cultivation brightened soil color and altered soil structure, reducing water available pores and organic carbon content while lowering soil pH, CEC, and exchangeable bases. However, base saturation remained unaffected despite changes in exchangeable bases
