Impact of sheep wool residues as soil amendments on olive beneficial symbionts and bacterial diversity.

In recent years the use of organic matter soil amendments, such as agricultural by-products, has been implemented with the aim of increasing soil fertility, while minimizing the environmental impact of agriculture. Sheep wool residues (SWR) have shown beneficial effects on plant nutrition and soil properties, while only few works assessed their impact on soil microbial communities. The main aim of this work was to investigate the possible valorization of two SWR types (scoured residues, white wool, WW, and carbonized scoured residues, black wool, BW) as organic soil amendments, in pot-grown olive trees, by evaluating their impact on soil bacterial communities and mycorrhizal symbionts.

[Folic acid for neural tube defects prevention: consumption and information in fertil-age women in Centro Cuyo Region].

Introduction: Neural tube defects are congenital malformations of brain and spinal cord. There is evidence that adequate amounts of folic acid supply to women before and during early pregnancy decreases the risk of having a neural tube defects affected child. Main sources of folic acid are food rich in folic acid, multivitamins with folic acid supplementation, and folic acid fortification of cereal products.
