Recycling trees onsite can sequester carbon, save water and increase crop yields, making it a climate-smart practice for California’s irrigated almond orchards, finds a study from the University of California, Davis.
Whole orchard recycling is when old orchard trees are ground, chipped and turned back into the soil before new almond trees are planted.
The study, published in the journal PLOS ONE, suggests that whole orchard recycling can help almond orchards be more sustainable and resilient to drought while also increasing carbon storage in the soil.
“To me what was really impressive was the water piece,” said corresponding author Amélie Gaudin, an associate professor of agroecology in the UC Davis Department of Plant Sciences. “Water is central to how we think about agriculture in California. This is a clear example of capitalizing on soil health. Here we see some real benefits for water conservation and for growers.”
