How to Increase Quality in the Vineyard?
California Ag Today recently caught up with Jerry Lohr when he shared how they continue to push the boundaries in their viticulture practices to produce award-winning wine.
J Lohr is a world recognized brand for its high-quality California wines. Proprietor Jerry Lohr says most of the quality wine is made in the vineyard. California Ag Today recently caught up with him when he shared how they continue to push the boundaries in their viticulture practices to produce award-winning wine.
"So the way to increase quality is just this constant studying, for instance, how much sun do we need on the, on the fruit? What the nourishment is - less is better in this case. Especially nitrogen. You use nitrogen for other crops, but not for grapes. The time of harvest, that pruning level, the crop level,” said Lohr.
"The time of watering is what we're talking about. So, we water very little in the summer, so we water on the spring. And I didn't want to tell people what they should do know, I just wanted to kind of tell about what our winemakers are doing,”
"So what we do is we make sure the soil profile is filled in the spring. We water very little in the summer. And then we water for veraison in the fall - from veraison to ripeness. So farming is about 75 to 90% of it (wine quality), others call it regulated deficit irrigation,” he noted.
"So that's a good way of describing it. Then we just go further than other people do, putting on more in the spring and less in the summer and that has water for the fall.”
Sensoterra is a worldwide leader in wireless soil moisture sensors helping growers to make wiser irrigation decisions based on soil moisture measurements at the active root zone. The robust design and wireless connectivity allow sensors to be placed from urban to remote rural areas; used for agriculture, horticulture, landscaping, and smart city projects.
Water timing, as mentioned by Jerry Lohr, is a key factor for achieving adequate soil health. When respecting the water necessities from the crop, growers can determine thresholds to control lower and higher irrigation setpoints, avoiding under- or over-irrigation common challenges in the field.
Sensoterra is a leader in wireless soil moisture sensing, founded in 2014, and based in Amsterdam with projects in agriculture, horticulture, nature restorations, and smart cities.
