In Italian vineyards it is common to find
more or less extended areas with chemico-physical or
biological soil deficiencies and problems in plant vigor
and grape production. A reduced agronomic functionality
is caused by wrong soil managements and
improper land preparation before vine plantations. A
strong land transformation alters, in fact, the existing
natural balance, causing loss of organic matter and
nutrients, erosions, reduction of available water and
metal accumulation. This phenomenon affects the
growth of vines and the grape yields. The aim of this
work is to evaluate the effect of degraded soils on the
vineyards of two Tuscan vine-growing regions
(Chianti Classico and Maremma Toscana). In two
farms, we have identified respectively three degraded
and three non-degraded areas in order to assess the
fitness of the vines and the quality of the grapes. We
found marked differences between degraded and
non-degraded areas: as expected, the soil conditions
have influenced the vigor of the plants, the production
and the grapes had an unbalanced maturation.
