: An Unknown Crop in Developed Countries with Great Potential for Industry and Adapted to Climate Change.

is originally a tropical crop with a fast development, little known in developed countries but cultivated since ancient times. It can adapt to regions affected by climate change, such as the Mediterranean basin, since it is a crop with a great resistance to high temperatures. In this study an in-depth bibliographical review was carried out by consulting different databases (Science Direct, FSTA, Scielo, Riunet, and Google Scholar) in order to find published scientific studies on the characteristics of this crop and its agronomic requirements.

Stabilisation of sewage sludge and vinasse bio-wastes by vermicomposting with rabbit manure using Eisenia fetida.

Changes in the chemical characteristics and biological parameters of Eisenia fetida were assessed by VER using (CO+VE) rabbit manure (Vo) spiked with sewage sludge (SS) or vinasse (V). Seven mixtures were used: Vo, control; Vo+SS at 10%, 30%, and 50% (SS1, SS2, and SS3); Vo+V at 10%, 30%, and 50% (V1, V2, and V3). SS vermicomposts had higher humus, nutrient and total metal contents, but less soluble salts (EC) than V vermicomposts.

Influence of organic matter transformations on the bioavailability of heavy metals in a sludge based compost.

The agricultural use of anaerobically digested sewage sludge (ADSS) as stable, mature compost implies knowing its total content in heavy metals and their bioavailability. This depends not only on the initial characteristics of the composted substrates but also on the organic matter transformations during composting which may influence the chemical form of the metals and their bioavailability. The objective of this work was to examine the relationships between the changes in the organic matter content and humus fractions, and the bioavailability of heavy metals.
