英文摘要: Abstract(#br)In plant nurseries devoted to the propagation of shrubs and trees for landscaping, gardening or forestry it is first concern to produce robust seedlings which resist the stress of transplanting to soil. The selection of appropriate growth media is crucial. Biochar, the product of pyrolysis of organic matter, has been suggested as a new organic amendment for soil or for soilless growth media. Biochar is usually strongly alkaline. We studied the possibility of acidifying biochar with nitric and phosphoric acids. The effects of raw and acidified biochars in peat-based substrates on rooting and growth of cuttings of Rosmarinus officinalis and in sandy soil-based substrates on growth of Phillyrea angustifolia seedlings were compared. The physical and chemical characteristics of...
