Efectividad del lodo textil en la producción y composición química del fruto de tomate

Abstract

those permitted by the environmental and health standards. However, we detected the presence of helminth eggs in higher values than those allowed by the standard in the fruits of plants treated with the highest concentration of sludge.

Lodo industrial textil en la producción de hortensias (Hydrangea macrophylla L.) en maceta

“…Even if potassium was generally low, the highest concentration was found in inflorescences, leaves and stems, but in root this effect was not observed. In stem, potassium content increased in proportion to the concentration of sludge in the substrate, which seems to indicate that the sludge promotes the absorption of potassium, even when, in previous studies low levels of potassium are reported in this type sludge (Narváez et al, 2013). Also, the reports from the literature show that sludge affects in different ways nutrient uptake by plants, for example, it is reported that the addition of sludge decreased Ca concentration in tobacco leaves (Kabata and Pendias, 1992) and in tomato fruits (Narvaez-Ortiz et al, 2013).…”

“…The incorporation of sludge to more than 10% increases electrical conductivity and pH of effluent and decreases crop development. In production of potted hydrangea the en este tipo de lodos (Narváez et al, 2013). Asimismo, los reportes en la literatura muestran que los lodos afectan de forma diferente a la absorción de nutrimentos por las plantas, por ejemplo, se reporta que la adición de lodos disminuyó la concentración de Ca en hojas de tabaco (Kabata y Pendias, 1992) y en frutos de tomate (Narvaéz-Ortiz et al, 2013).…”

“…In northern Mexico, there are 62 waste water treatment plants, which produced about 475,000 tons of sewage sludge (95 000 t dry), which could be used as fertilizer in industrial and forage Narváez et al (2013). Con base en los resultados positivos obtenidos en los estudios anteriormente citados, el uso de los lodos industriales textiles se podría ampliar a especies ornamentales y en particular ornamentales de maceta.…”
