Risiko des Eintrags von Phosphor in den Hallwilersee durch Bodenerosion [PDF]

Geographica Helvetica, 2015
An important factor in the release of phosphorus by soil erosion, with corresponding consequences on the quality of surface waters, is the formation of aggregates and their stability.

Is soil phosphorus fractionation as valuable as we think?

, 2021
The recent article by Barrow et al. (2020) concerning "The soil phosphate fractionation fallacy" is a welcome cautionary paper for phosphorus scientists to question how they approach the interpretation and practical use of phosphorus fractions in ...

Evaluation of phosphorus mobility in soil using different extraction methods

Plant, Soil and Environment, 2009
Soil samples (from Czech and German long-term field experiments) were used to estimate different soil phosphorus (P) fractions. More than 200 topsoil (0-30 cm) samples from different fertilizing treatments were taken.

Effects of biochar on phosphorus fraction, phosphatase activity, and phosphorus-solubilizing bacterial abundance: a phosphorus-depleted biochar design

Frontiers in Environmental Science
PurposeBiochar application is considered a promising strategy for mitigating agricultural phosphorus (P) shortages. However, it remains uncertain whether biochar enhances soil phosphorus availability for crops beyond functioning as an external phosphorus

Effects of 42-year long-term fertilizer management on soil phosphorus availability, fractionation, adsorption–desorption isotherm and plant uptake in flooded tropical rice

Crop Journal, 2015
Soil phosphorus (P) fractionation, adsorption, and desorption isotherm, and rice yield and P uptake were investigated in flooded tropical rice (Oryza sativa L.) following 42-year fertilizer and manure application.

Phosphate Sources and Their Placement Affecting Soil Phosphorus Pools in Sugarcane

Agronomy, 2018
Phosphate fertilizer placement at sugarcane (Saccharum spp.) establishment can strongly influence the distribution of soil P pools over crop cycles, and has a great influence in the availability of this nutrient to plant uptake. Our main objective was to
