Intensive agricultural practices of past decades—
such as mechanical cultivation on steep vineyard
slopes—can endanger soil fertility. In addition,
climate change scenarios predict heavier rainstorms,
which can further accelerate soil degradation.
Therefore, the use of cover crops in the inter-row has a
special importance, particularly on steep slopes and in
organic agriculture. A species-rich cover crop mixture
helps not only in preventing erosion and providing
easier cultivation, but has also positive effects on soil
structure, soil fertility and ecosystemfunctions (Bauer et
al. 2004; Hofmann et al. 2008). We began to develop
and test several species-rich cover crop mixtures in
spring of 2012 in Hungarian vine regions. During the
experiments, three species-rich cover crop mixtures
(Biocont-Ecovin mixture, mixture of legumes, mixture
of grasses and herbs) were compared in vineyards of the
Tokaj vine region. Each mixture was sown in three
subsequent inter-rows at each site of the experiment.
In the control blocks, unsown inter-rows and mechanically
cultivated inter-rows were located subsequently
next to each other. We studied weed control, yield
quantity and must quality in every treatment. We found
that the cover of weeds was lower in every treatment
compared to the unsown control plots for 2013; thus,
cover crops suppressed the weeds of the inter-rows
effectively. Most examined indices of grapevines were
not significantly affected by the applied cover crops.
However, the yield loss results show that under
Hungarian climate, the soil coverage in every second
inter-row is more recommendable than subsequent
seeding, where total erosion control is not required.
The interest of the vine growers shows the importance
of the topic; thus, we involved other wine regions of
Hungary in our further experiments.
