When you think of eco-friendly practices, big machinery isn’t the first thing that comes to mind.
But at our estate Margarita Vineyard, a couple of iron giants—specifically modern multi-function, multi-row tractors—have become an integral part of our sustainable winegrowing program.
Our two multi-row tractors, including the French-made Pellenc pictured here, have taken the place of six traditional tractors.
Because they serve multiple rows at a time and offer simultaneous function for mowing, trimming, pre-pruning and other uses, they have reduced our tractor passes (ie: travel up and down the vine rows) by more than 80 percent. This, in turn, has minimized soil compaction while cutting diesel fuel consumption.
Tractors are a necessary part of farming, but tractor passes cause soil compaction over time. Compaction results in stormwater runoff, which wastes precious water while exacerbating soil erosion. When the compaction becomes too great, the soil must be ripped—which requires more tractor passes and fuel consumption.
So ironically enough, these big machines have significantly lightened our environmental footprint at Margarita Vineyard. They were a huge investment for us, but also a wise one in the long run.
