Availability of a soluble phosphorus source applied to soil samples with different acidicity levels Disponibilidade de fósforo de uma fonte solúvel aplicada em amostras de solos com diferentes níveis de acidez

open access: yesRevista Brasileira de Ciência do Solo, 2010
Considerations on the interactions of P in the soil-plant system have a long history, but are still topical and not yet satisfactorily understood. One concern is the effect of liming before or after application of soluble sources on the crop yield and ...

Effect of magnetic field on hydraulic conductivity and cation displacement in soil in the semi‐arid region of Brazil

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Population growth intensifies the production of waste from agricultural and industrial sources, among others, directly impacting soil and water resources. The use of techniques involving magnetic field applications has been investigated as a potential approach to improve soil–water interactions, although its effects are still not fully ...

Electrolysis‐treated biosolids enhance wheat growth and alter soil health parameters

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Biosolid‐based fertilizers can benefit agriculture by supporting circular nutrient economies, reducing fertilizer costs, and minimizing environmental impacts compared to inorganic fertilizers. A 125‐day greenhouse experiment was conducted to assess the effects of electrolysis‐treated biosolids on wheat (Triticum aestivum) growth and soil ...

Phosphorus Sorption Capacity and Its Relationships With Soil Properties Under Podzolic Soils of Atlantic Canada

open access: yesFrontiers in Soil Science, 2022
Repetitive long-term fertilizer application leads to phosphorus (P) accumulation in agricultural soils. This can pose environmental risks if the soil’s phosphorus storage capacity is not well understood and considered when planning nutrient management ...

Cotton rotation with single and multispecies cover crops affects yield, quality, and economic outcomes

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Cover crops (CCs) have gained popularity in continuous crop production systems due to their agroecosystem benefits. This study evaluated the effects of nine CC treatments (single or multispecies) and no cover crop (noCC) on cotton (Gossypium hirsutum L.) growth characteristics, production, and economic returns in the Mid‐South United States ...
