Identification and phytoremediation potential of spontaneous species in vineyard soils contaminated with copper. Copper (Cu) contents in vineyard soils due to the application of cupric fungicides cause changes in the native covering flora. Under these conditions, the surviving individuals accumulate the metal in... ... Repositório: BDPA Ano de publicação: 2021

Phytoavailability of copper in industrial by-products and mineral fertilizers. Abstract: Alternative copper (Cu) sources could be used in fertilizer production, although the bioavailability of copper in these materials is unknown. The objective of this study was to evaluate the... ... Repositório: BDPA Ano de publicação: 2015
Evaluation of tropical legume cover crops for copper use efficiency. Cover crops are important components of cropping systems due to their role in improving soil quality. Lack of adequate levels of soil micronutrients prevents the success of cover crops in highly weath... ... Repositório: BDPA Ano de publicação: 2014
Liming as a means of reducing copper toxicity in black oats. Soils which are cultivated with grapevines have high available copper (Cu) content, which can be toxic to cover crops cohabiting vineyards, such as black oats. This study aimed to assess the effect of... ... Repositório: BDPA Ano de publicação: 2018
