Phosphorus in Soils and Plants

The book delves into the indispensable role of phosphorus (P) in plant physiology and soil dynamics. It elucidates how P serves as a fundamental macronutrient vital for various biological processes, including energy transfer, cellular division, DNA synthesis, and enzymatic functionality. The book explores P's intricate interplay with soil microorganisms, emphasizing their critical role in P cycling and the subsequent impact on soil fertility. A comprehensive discussion on the availability of P in soil unfolds, exploring factors such as organic matter content and soil properties that influence P accessibility. It distinguishes between organic and inorganic forms of P, elucidating their presence in soils and their diverse effects on plant uptake, influenced by soil pH, texture, and moisture. Moreover, it unravels the pivotal role of plant-related factors—root exudates, plant species, and health—in modulating P absorption. The book navigates through various phosphorus fertilizers, delineating their types and applicability in crop cultivation based on soil and crop requirements.
