Lettuce growth characteristics as affected by fertilizers, liming, and a soil conditioner

Abstract: The aim of this work was to test fertilizers, liming, and levels of a soil conditioner produced from leonardite, composed by humic and fulvic acids on "iceberg" lettuce growth characteristics. The experimental design was completely randomized in a 5×3×2 factorial scheme, with 5 levels of soil conditioner (

“…When technogenic waste such as sewage sludge, ash, mixed biodegradable municipal waste and residues from biogas production are used in compost production, soil and plants are often contaminated with heavy metals (Zn, Mn, Cu, Ni, Cd and Cr), which can pass to the food chain (Greger et al, 2007;Uriah, Shehu, 2014;Carvalho, Marchi, 2015). Quite often such composts include persistent organic pollutants: polycyclic aromatic hydrocarbons, di(ethylhexyl) phthalates, polychlorinated biphenyls, etc., which have a toxic effect on plants and are accumulated in soil (Paradelo et al, 2008).…”

“…One of the most popular ways of utilizing biodegradable waste is composting and using composts for plant fertilization (Uriah, Shehu, 2014). However, the value of composts produced from different kinds of biodegradable waste varies greatly (Fuchs et al, 2008;Carvalho, Marchi, 2015).…”
