The bioavailable contents of heavy metals in karstic soils are a subject increasing concern since the uptake by plants can pose severe threat to food safety and public health. However, their effective factors poorly understood karst regions. Calcareous soil red developed from carbonate clastic rocks, respectively, were chosen typical region (Guilin) southwestern China, total (CT) available (CA)...

Understanding the diversity and community structure of arbuscular mycorrhizal fungi (AMF) is important for potentially optimizing their role in mining phosphorus (P) in agricultural ecosystems. Here, we conduct a comprehensive study to investigate the vertical distribution of AMF in a calcareous field and their temporal structure in maize-roots with fertilizer P application over a three-year pe...

Abstract Phosphorus (P) reactions in calcareous soils limit the concentration of P soil solution for plant uptake. Calcareous with high calcium carbonate content (CaCO 3 ) and pH have low fertiliser efficiency, leading to crop deficiency limited productivity. The aim this work was test if acidifying amendments could reduce improve solubility nutrition biomass. Three varying CaCO (14–29% w/w) we...

Knowledge of transport and degradation of polycyclic aromatic hydrocarbons (PAHs) is important in assessing PAH contamination of soils and water resources. The transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the Shadegan wetland (Khozestan, Iran) considering a column study in laboratory conditions. The PAHs were added ...

Zinc (Zn) deficiency is a major problem for many people living on wheat-based diets. Here, we explored whether addition of green manure of red clover and sunflower to a calcareous soil or inoculating a non-indigenous arbuscular mycorrhizal fungal (AMF) strain may increase grain Zn concentration in bread wheat. For this purpose we performed a multifactorial pot experiment, in which the effects o...

After collecting calcareous corpuscles from plerocercoid of Spirometra mansoni (sparganum), we evaluated the antigenic values of calcareous corpuscles binding proteins obtained from the cyst fluid of Taenia solium metacestodes. Immunoblot analysis revealed that cysticercosis patient sera strongly recognized 10 and 95 kDa calcareous corpuscles binding proteins. This result demonstrated that calc...
