The Role of Tithonia Diversifolia in Suboptimal Soil Fertility

Abstract

Tithonia diversifolia, commonly known as Mexican sunflower, has garnered significant attention for its potential role in enhancing soil fertility, particularly in suboptimal soil conditions. This study explores the effectiveness of Tithonia diversifolia as a green manure, analyzing its ability to improve nutrient availability and soil structure in areas with low fertility. The plant's rapid growth, high biomass production, and rich nutrient content, particularly nitrogen and phosphorus, make it a promising organic amendment for degraded soils. Through a series of field experiments and soil analyses, this research demonstrates that the incorporation of Tithonia diversifolia into suboptimal soils significantly increases organic matter content, enhances microbial activity, and improves nutrient cycling, leading to better crop yields. Additionally, the study discusses the environmental and economic benefits of using this species as a sustainable alternative to chemical fertilizers in low-input farming systems. Despite the positive outcomes, challenges such as the labor-intensive nature of harvesting and application need further consideration. Overall, this research contributes to the growing body of knowledge on the potential of Tithonia diversifolia in supporting sustainable agriculture in regions facing soil fertility challenges.
