Phosphorus fractions and correlation with soil attributes under no-tillage and crop-livestock integration systems in Cerrado of Goias

Semina: Ciências Agrárias, 2015
The objectives of this study were to evaluate the fractions of organic phosphorus (P) and inorganic soil, and to determine the remaining phosphorus (Prem) and correlate the fractions of P with some soil attributes in areas with different land use systems

Soil Phosphorus Fractionation as Affected by Paper Mill Biosolids Applied to Soils of Contrasting Properties

Frontiers in Environmental Science, 2020
Industrial by-products such as paper mill biosolids (PBs) have been used as fertilizers and amendments in agriculture for many decades. However, their content of plant essential nutrients including phosphorus (P) varies largely with sources, and ...

Phosphorus fractions and correlation with soil attributes in a chronosequence of agricultural under no-tillage

Semina: Ciências Agrárias, 2016
In no-tillage (NT) soils, changes in the quantity and quality of soil organic matter (SOM) have been observed over time. These changes can interfere with the dynamics of P in surface soil layers.

Phosphorus Fractionation in Soils Fertilized with Recycled Phosphorus Products

Journal of Soil Science and Plant Nutrition, 2019
Phosphorus (P) will be exhausted, and its recovery and cycling will play a pivotal role in agricultural systems. Different technologies have been developed to recover P from waste materials, such as mono-incineration, acid digestion, and coprecipitation of P from wastewaters.
