Phosphorus fractionation and distribution in Nitisols of the central Ethiopian highlands affects soil nutrient management strategies in barley (Hordeum vulgare L.) production [PDF]

open access: yesPeerJ
Optimizing nutrient management is essential for sustaining crop productivity on fertilizer-unresponsive acidic soils, particularly through a comprehensive understanding of soil phosphorus (P) dynamics.

Stratification of soil phosphorus forms from long-term repeated poultry litter applications and its environmental implication

open access: yesEnvironmental Challenges, 2021
Increasing demand for poultry products has led to an intensification of concentrated poultry feeding operations resulting in the generation of enormous amounts of poultry litter (PL). For example, in 2017 the southeastern U.S.

Comparison of analytical procedures for measuring phosphorus content of animal manures in China [PDF]

open access: yesFrontiers of Agricultural Science and Engineering, 2019
The concentration and components of manure phosphorus (P) are key factors determining potential P bioavailability and runoff. The distribution of P forms in swine, poultry and cattle manures collected from intensive and extensive production systems in ...

Soil organic phosphorus in Eucalyptus plantations, Brazil: extraction methods [PDF]

open access: yesScientia Agricola, 2023
In-depth knowledge of total soil organic phosphorus (TPO) as a potential P source for plants allows for a comprehensive understanding of the adoption of an efficient management system of phosphorus fertilization in forest plantations.

The reactivity of dissolved and suspended particulate phosphorus pools decreases with distance downstream in the Yellow River

open access: yesCommunications Earth & Environment, 2023
The Yellow River is a potentially important source of terrestrially derived phosphorus to the phosphorus limited Bohai Sea. However, seasonal variation in concentrations, partitioning and bioavailability of dissolved and particulate phosphorus along the ...

Phosphate Management for High Soybean and Maize Yields in Expansion Areas of Brazilian Cerrado

open access: yesAgronomy, 2023
The low phosphorus (P) availability is considered one of the most limiting factors for suitable crop production in Brazilian Cerrado areas. We aimed to define the best P fertilizer management for maximum soybean and maize grain yield and minimum soil P ...

Availability and fractionation of phosphorus in soils with different physicochemical characteristics

open access: yesAgro@mbiente On-line, 2020
The total content of phosphorus (P) within soil does not reflect its availability for plants, the available form depending on the physical and chemical characteristics of the soil.

Fractionation of soil phosphorus in a long-term phosphate fertilization [PDF]

open access: yesJournal of the Serbian Chemical Society, 2012
The changes in inorganic and organic phosphorus (P) fractions of soil resulting from long-term fertilization (40 years) were investigated. In order to improve understanding of the sink and sources of phosphorus, P-fractions were extracted from soil ...

Characterization of Phosphate Compounds along a Catena from Arable and Wetland Soil to Sediments in a Baltic Sea lagoon

open access: yesSoil Systems, 2023
Phosphorus (P) is an indispensable nutrient for arable crops, but at the same time, contributes to excessive eutrophication in aquatic ecosystems. Knowledge about P is essential to assess the possible risks of P being transported towards vulnerable ...
