In this respect, the authors previously assessed (Chalkos et al.,2010) the potential of using composts derived from spearmintand sage as soil amendments in tomato cultivation. To this end,this paper considers the incorporation of intact (above growndry biomass) material from aromatic plants directly to the soil,that is, with no prior composting, to improve productivity intomato (Lycopersicon esculentum L.) seedlings. In this manner, thesoil amendment practice becomes easier, faster and more cost-effective. To this aim, dried spearmint (Mentha spicata L.) and sage(Salvia fruticosa Mill.) tissues are considered for the purpose andtheir effectiveness is gauged by monitoring a comprehensive listof plant and soil parameters. It is noted that the choice of tomatoas a case-study has been motivated by the fact that it is amongthe ten most important crops in South Eastern Europe (FAO, 2012)and by the fact that it is often used in rotations (Poudel et al., 2001)and, therefore, it holds an important role in alternative farming sys-tems. Our interest was focused on tomato seedbed management,specifically on the requirement of producing healthy and rapidlygrowing seedlings in nurseries. It is estimated that a reduction ofthe transplanting period by only 3–5 days provides surplus ben-efit on the income of the tomato seedling suppliers. In addition,growers aim at producing robust seedlings as early in the growingseason as possible, so as to minimize infections and subsequentlymaintain productivity in the greenhouse. Therefore, any manip-ulation that might satisfy the above requirements is of outmostimportance.
