Abstract
Modern agricultural practices, characterized by the prevalent use of high-inorganic phosphate fertilizers, have raised significant environmental concerns due to their non-renewable nature and adverse impact on the food chain production (Withers et al., 2014). This study addresses the challenges associated with these fertilizers, particularly their limited accessibility to plants in acidic soils, where inorganic phosphorous fixations induced by aluminum (Al) and iron (Fe) metals hinder nutrient absorption (Ch'ng et al., 2014). The consequences of relying on such chemical inputs for agriculture are far-reaching, contributing to environmental issues like pollution, soil degradation, and the depletion of essential microorganisms responsible for facilitating nutrient uptake by plants. Phosphorous, a crucial nutrient for plant growth and development, plays a pivotal role in various stages of the plant life cycle. The availability of phosphorous in the soil is paramount for robust root development and overall plant health. Unfortunately, a substantial portion of phosphorous in soils exists in diverse forms, including organic and inorganic compounds, rendering it inaccessible to plant roots. Insufficient phosphorous levels in the soil can result in stunted plant growth, inadequate development, and compromised crop yields. This research aims to explore sustainable alternatives to high-inorganic phosphate fertilizers, considering their detrimental effects on the environment and agricultural productivity. By delving into the intricate dynamics of phosphorous availability in acidic soils and its impact on plant growth, the study seeks to identify eco-friendly practices that enhance nutrient accessibility to plants without compromising soil health. The methodology involves a comprehensive review of existing literature, incorporating insights from Withers et al. (2014) and Ch'ng et al. (2014), among others, to construct a holistic understanding of the challenges posed by current agricultural practices. The findings from this research are anticipated to contribute valuable insights into the development of sustainable agricultural strategies, fostering a balance between enhanced plant nutrition, environmental conservation, and the preservation of soil ecosystems.
