Wetland degradation promotes soil P fraction transformation by altering P-cycling functional genes and metabolic pathways [PDF]

Frontiers in Microbiology
Global wetlands have undergone varying degrees of degradation due to intense disturbances from global climatic and environmental changes, and human activities such as overgrazing and drainage.

The Application of Fertilizer Phosphorus Affected Olsen P and the Phosphorus Fractions of Hedley Method in Black Soil

Agronomy, 2022
Olsen phosphorus (Olsen P) is an important indicator of soil labile phosphorus. Determining the effect of fertilization on Olsen P and P fractions (labile phosphorus, medium labile phosphorus and stable phosphorus) can guide the application of phosphate ...

Inorganic phosphorous, lime and vermicompost induced changes on phosphorus fractions and other properties of acidic Soil of Cheha district, Ethiopia

Journal of Science and Inclusive Development, 2023
In acid soils, soluble inorganic phosphorus is fixed by aluminum and iron, so that phosphorous availability to plants would be inhibited. Thus, an incubation study was conducted to evaluate the effects of lime, vermicompost, and mineral P fertilizer on ...

Short Term Effects of Revegetation on Labile Carbon and Available Nutrients of Sodic Soils in Northeast China

Land, 2020
In response to land degradation and the decline of farmers’ income, some low quality croplands were converted to forage or grassland in Northeast China. However, it is unclear how such land use conversions influence soil nutrients.

Phosphorus fractions in an agricultural chronosequence under tillage regimes in the Cerrado area in Goiás, Brazil

Semina: Ciências Agrárias, 2016
The increase in the amount and quantity of soil organic matter (SOM), as well as the use of phosphorus-based fertilizers in the superficial soil layer in areas under tillage regimes (TR), may affect phosphorus (P) dynamics in the soil.

The influence of degree of peat decomposition on phosphorus binding forms in fens [PDF]

Mires and Peat, 2007
Re-wetting of drained fens can release phosphorus, introducing a eutrophication risk for associated aquatic ecosystems. Characterisation of the different forms of organic and inorganic bound phosphorus in the peat is an important step towards the ...

Influence of parent material on organic phosphorus fractions in vineyard soils in Santa Catarina, Brazil

Revista Ambiente & Água, 2020
Phosphorus (P) is an essential element for vineyard productivity. This study assessed the influence of parent material on organic P fractions in vineyard soils of basaltic and rhyodacitic origin.

Phosphorus Forms in Ultisol Submitted to Burning and Trituration of Vegetation in Eastern Amazon

Revista Brasileira de Ciência do Solo, 2016
The use of fire to prepare agricultural areas is a technique still used by small farmers in eastern Amazon. This type of management changes the dynamics of soil nutrients, especially phosphorus, which constitutes the most limiting nutrient for crop ...
