Technological Alternatives with Low Consumptions to Regenerate the Degraded Grasslands

This paper had as main objective the comparison of new technological solutions for degraded grassland using a grasslands regeneration machine and a trailed vindrover, with the conventional technologies. The grasslands regeneration machine performs several operations in one pass, as follows: soil tillage in narrow strips, direct seeding of an herb seed mixture into the vegetal cover and light compaction of the soil over the seeds for a proper contact, in order to obtain a good germination. The trailed vindrover is designed to the harvest and conditioning forage technology, running in a single pass operation of mowing, crushing and left on the ground to dry naturally. Experimental researches were carried out in two locations, namely National Institute of Research-Development for Machines and Installations designed for Agriculture and Food Industry- INMA Bucharest and Grasslands Research-Development Station- SCDP Vaslui, in the agricultural year 2014. For each technological link the following parameters were determined: fuel consumption per hour, fuel consumption per surface unit, hourly working capacity and labor consumption. Analyzing the comparative diagrams, it was observed that total average values of parameters obtained in the two locations in spring and late summer by applying the new technological variants were smaller than the ones obtained by applying conventional technologies. The new technological solutions for regeneration of degraded grasslands involve less fuel and labor consumption, being more environmentally friendly than conventional technologies used so far.
