Abstract:

The increase in soil occupation without any concern for the natural resources has caused a reduction in the forest cover not only in the state of Parana, but in the other Brazilian states, that has developed throughout the times in adverse environmental conditions. Consequently, there has been a reduction in surface roughness, which together with the climatic factors has negatively impacted on crop productivity. Among climatic factors, the increase in wind speed, due to the lack of forest cover, is one of the contributing factors of soil erosion, the acceleration of the cooling down plants in conditions of low temperature and the desiccation of plants in condition of high temperature. However, the damage to crops caused by wind can be prevented or minimized by the use of windbreaks curtain; they are shields that work strategically against the direction of strong winds. Such curtains, natural or artificial tend to reduce the wind speed and therefore the harmful effects caused by its high speed. Thus, this work is aimed to investigate an alternative of wind speed control. The windbreaks curtain of Eucalyptus dunnii Maiden was utilized in a soybeans planting area of 3.31 hectares, in order to make comparison with another same area and size (dimensions) located in Cascavel, Parana State, Brazil. The use of positional windbreak curtains took into account the predominant wind direction in the southeast/northwest (SE/NW), obtained by the graph “Wind Rose” based on data from 1978, from Institute of Technology and Environmental Information (SIMEPAR). After harvesting, the soil samples were collected for chemical analysis and by geostatistical techniques it was verified the behavior of spatially referenced soybean yield and some soil chemical attributes. The results show that the windbreaks curtain implantation had a positive influence on soybean yield, i.e. increased productivity around the curtain windbreaks. In addition, the species choice took in to consideration the acceptance in the market, which would allow the producer to obtain additional income when cutting the curtain.
