In terms of ensuring the sustainability and permanent soil fertility, the key role in viticulture is played by short-term and permanent greening in the interrow. Additionally, the introduction of these systems can positively affect flora and fauna species diversity in monoculture plantations, like vineyards, which are an integral part of the contemporary cultural landscape. This paper focuses on the evaluation of penetrometric measurements carried out in the years of 2015 and 2016 at 5 sites with different soil conditions and different greening (a mixture of annual greening, a mixture of durable greening, a mixture of durable greening with various plants species, a mixture of durable greening for arid conditions and a mixture of annual greening for pollinators) in the region of South Moravia. Penetrometer measurements were conducted using a manual penetrometer EIJKELKAMP. The water content in the soil at the time of the measurement, expressed in weight percentage was determined by the gravimetric method. Soil samples for moisture determination were collected in triplicate from the depths of 0-0.10 m, 0.10 to 0.20 m and from 0.20 to 0.30 m. The measured results show that the average values of penetrometric resistance from the soil surface to the depth, in different habitats and treatments mixtures ranged in 2015 at a depth 100-200 mm between 1.66-1.83 MPa, at a depth of 200-300 mm between 2.20-2.32 MPa and at a depth 200-300 mm between 2.43-3.19 MPa. In 2016, then the rate was at a depth 100-200 mm between 1.40-1.50 MPa, at a depth 200-300 mm between 1.52-1.67 MPa and at a depth 200- 300 mm between 1.97-2.15 MPa. The results showed that a treatment of a mixture of annual greening and a mixture of durable greening with various plant species differs only slightly and based on the evaluation they are clearly the best. Comparisons between the two monitored years show very good agreement in the evaluation of alternatives.
