Conservation & Biodiversity
Numerous vineyards have utilized sheep and goats in their vineyard for grazing but most only during the winter. Kelly Mulville was on a mission to design a vineyard for year-round grazing to restore the ecosystem with livestock. Using the sheep will eliminate all suckering and tipping, dramatically reduce fertilization, decrease irrigation use, and lower labor costs. Listen in as Kelley explains the trial process for tips on how to set up your own vineyard for year-round grazing.
Every vineyard has a portion of the property that is non-productive, but are there ways to maximize the benefits of this land? Chamisal Vineyards found the answer to this question with a Miyawaki Mini-forest. With soil amendments and planting 400 to 500 native plants at a high density, this process enables the forest to establish three to four times as rapidly as it would in a natural setting. The established forest will not only proffer a habitat for local fauna but, also provide carbon sequestration.
In an era of declining resources, US-based vineyard consultant Kelly Mulville writes of his experience to develop viticulture methods that eliminate the need for mechanical or hand cultivation, mowing, tillage and suckering while simultaneously improving soil health sequestering carbon), increasing biodiversity and reducing irrigation needs.
Using sheep to graze vineyards has many benefits including lowering the carbon footprint, fewer tractor passes, and reduced herbicide use. Kelsey Brewer, Ph.D. Candidate at the University of California at Davis has been researching how these living lawnmowers impact nutrient and energy flows in the eco system.
What, bury charcoal in the vineyard? Biochar is a specialized form of charcoal made from waste woody biomass at high temperature in the absence of oxygen. Doug Beck, Science Officer at Monterey Pacific in Monterey California, shares how biochar and compost amendments improve nutrient efficiency, improve water holding capacity, and positively impact yields.
Local Perinet Winemaker Antoni Sanchez-Ortiz notes how years of abandonment has lead nature reestablish its place among the vines, hazelnut, olives, and forest. To maintain this balance of nature and winemaking, the winery has established an ESG (Environmental, Social, Governance) initiative.
The resource concentration hypothesis looks at how the advent of modern agriculture as monoculture created an environment where pests can grow faster because their resource, the crop, is more prevalent. Biodiversity is fundamental for pest management and Daniel Paredes, Postdoctoral Fellow at the University of California Davis, in the department of Wildlife Fish and Conservation Biology, is studying how sustaining natural habitat around vineyards can increase biodiversity.
David R. Montgomery defines regenerative agriculture as leaving the land better off and more fertile as a consequence of cultivation. In this research, he has defined three principals to build soil fertility; minimal disturbance, cover cropping, and growing a diversity of crops. David has studied the success of these principals in agricultural systems around the world, from subsistence farmers to large commodity crops in North America.
50-million-year-old reserves of humified organic matter are a substance called lignite. It is commonly known as brown or soft coal, a substance usually equated with energy production. Researchers at the Technical University of Dresden have found that this very old, carbon rich plant material has the same building blocks as humus – the organic matter reserves found in soil. Virginia Corless, Chief Growth Officer at Novihum Technologies, explains how reacting lignite with nitrogen has created a new soil amendment to improve nutrient retention, water storage, and the vitality of the microbiome.
