We were firmly back into vineyard work last week, planting some winter cover crops. These are diverse seed mixes with 13 different species (lots of clovers, phacelia, oats, peas, radish, cereals etc) which help support the soil biome and improve soil health. Different species of plants generate different types of exudates (including carbohydrates) through their roots, which in turn feed different types of microbiology underground. That microbiology (or biome) plays a key role in making nutrients available to the plants including the vines, as well as increasing the overall ecosystem resilience.
Some of the plant species we include in the seed mix persist for multiple seasons which helps carry that beneficial effect on past the first year. Ultimately after 3-4 years though, the grasses start to outcompete the other plants so it’s worth resowing them to keep that biodiversity above and below ground.
Often we plant some of these cover crops in spring, but with the anticipated El Nino weather pattern this year, we’re getting these in early in the hope that we get more regular rainfall and better establishment through winter.
Our old seedbox was working really well, until the temporary weld from three years ago failed! Into town today to get it fixed properly before finishing the job - persistence is everything sometimes! Then we just need some rain - it’s been a dry autumn on the East Coast this year.
