Multivariate Assessment of Nutrient Absorption and Soil-to-Plant Transfer Factors in Moc Chau Crops Using k₀-INAA

Year: 2025

Type: article

Abstract: Absorption and accumulation of nutrients in various crop species in Moc Chau town in Son La province of Vietnam, have been examined using multivariate analysis. The nutrient concentration in soil decreases in the following order: K > Fe > Na > Mn > Zn > Rb. Crops prioritize the absorption of nutrients based on their growth requirements, with potassium (K) being the most abundant nutrient in the plants, followed by trace elements such as iron (Fe), sodium (Na), manganese (Mn), zinc (Zn), and rubidium (Rb). The average transfer coefficients for K, Fe, Na, Mn, Zn, and Rb are 2.91, 0.00307, 0.45, 0.037, 0.15, and 0.22, respectively. Multivariate analysis indicates that the ability to absorb and accumulate elements are species-dependent, highlighting the influence of plant type. The findings imply that plants within the same group require similar fertilization and soil treatment strategies.
