Internal loading potential of phosphorus in reservoirs along a semiarid watershed
RBRH, 2020 Sediments are important to nutrient dynamics, especially due to phosphorus internal loading. Several studies have observed that internal loading could prevent water quality from improving in lakes, even when external phosphorus loading is significantly ...

Phosphorus Fractions and Their Transformations in Entisol
Journal of Agricultural Science, 2018 The availability of phosphorus in the soil is a factor that directly interferes with its absorption by plants. This availability can be influenced by the texture, dose of the phosphate fertilizer and the time of contact with the soil. This study aimed to quantify the organic and inorganic fractions of P accumulated in a sandy soil receiving doses of ...

Metagenomics of the Effect of Long-Term Straw Return on the Phosphorus Cycle in Meadow Black Soil
Agronomy, 2023 Returning crop straw to the soil is an effective measure to increase soil fertility and maintain crop yield in agroecosystems. In this study, we conducted a 34-year field experiment (1984–2017) to investigate the relationships among the impacts of straw ...

Responses of soil phosphorus fractions to gap size in a reforested spruce forest
, 2016 Gap created by thinning is a vital practice for the management of degraded forest. However, little information is available about the change in soil P fractions following the gap formation. This study investigated the effects of three gap sizes on soil P

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.

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 ...
