Soil Phosphorus Characterization and Total Element Analysis

TL;DRAbstract

Abstract Phosphorus is a major element in soil organic matter, and in natural terrestrial ecosystems is derived from the weathering of minerals in parent rock material. It is usually the second most limiting nutrient for terrestrial primary production (after nitrogen) and is often the primary limiting nutrient in freshwater ecosystems. Due to its critical role in controlling aquatic primary production, there is an increased concern over runoff of P from terrestrial to aquatic ecosystems and the role of Pin affecting water quality. Studies of P cycling and availability pose a challenge to agronomists and ecologists, in part because P occurs in soils in many different physicochemical forms that are operationally difficult to define, and in part because Pis involved in a myriad of biological and chemical processes. The cycling of P can be controlled by inorganic chemical reactions, but in many systems the turnover of organic P controls the availability of P to plants through organic matte
