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

Frontiers 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 ...

Is Mehlich 3 soil extraction a suitable screening method for determination of some risk elements?

Plant, Soil and Environment, 2021
Legislation limits for risk elements (As, Be, Cd, Co, Cr, Cu, Ni, Pb, V, Zn) in agricultural soil in the Czech Republic are given for the content of elements extracted by aqua regia. This extraction is time consuming and environmentally unfriendly.

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

Agrosystems, 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

Agrosystems, 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 ...

Correlation and calibration of Mehlich‐3 sulfur for Kentucky bluegrass

Crop Science
Abstract Sulfur (S) is a crucial macronutrient for turfgrass growth, and declining atmospheric deposition has increased the risk of S deficiency. Reliable Mehlich‐3 soil test interpretations for S are lacking for turfgrass.

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

Agrosystems, 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 ...
