Nevertheless, using sludge as fertilizer for crops to produce food or feed is limited due to thepresence of trace contaminants such as heavy metals. Therefore, the aim of this study was to investigatethe use of sewage sludge as a nutrient source for bioenergy crops such as fibre hemp, oilseed rape andwhite lupin. Specific attention is paid to the biomass accumulation and the quality of the plant material aswell as the ability of the crops to take up the heavy metals from soils in order to ensure that the amount ofpollutant does not cumulate.Fibre hemp (Cannabis sativa L.) cv. Uso, oilseed rape (Brassica napus L.) cv. Wildcat and whitelupin (Lupinus albus L.) cv. Amiga were sown in 5-L pots in a greenhouse. Three potting mixes wereused: a standard peat-based potting compost with 50% sludge, sludge with peat (50%:50% by weight), or100% sludge, and a constant mass of 666 g potting mi...

In two pot experiments, germination and growth of maize (Zea mays L., cv. Ronaldino), fiber hemp (Cannabis sativa L., cv. Uso 31) and oilseed rape (Brassica napus L. ssp. oleifera (DC.) Metzg., cv.Wildcat) were studied when treated with sewage sludge and biogas sludge in comparison with chemical fertilizer during 2011. The experiment included five treatments: soil+sewage sludge, soil+fertilizer, sand mixed with peat+sewage sludge, sand mixed with peat+fertilizer, and soil+biogas sludge. Sludge content was calculated to deliver the same content of nitrogen that was added for each species. Germination percentage was recorded at 7, 10 and 14 days after sowing. Length and dry weight of roots and shoots were measured at 14 days after sowing for all species.Sewage sludge treatments resulted in higher germination percent...

Tissue cultures also provide cells and culture medium from which enzymes and cell wall polymers can easily be separated for further studies. Tissue cultures with tracheary element differentiation or extracellular lignin formation have provided useful information related to several aspects of xylem and lignin formation. In this chapter, methods for nutrient medium preparation and callus culture initiation and its maintenance as well as those for protoplast isolation and viability observation are described. As a case study, we describe the establishment of a xylogenic culture of Zinnia elegans mesophyll cells.
