Cover crops and mulching decrease greenhouse gas emissions of fruit tree orchards

Fruit tree orchards should be climate friendly because atmospheric carbon is stored during long periods of time in trees. Orchards also produce woody renewable energy. However orchard soils, which store carbon, are often eroded under the Mediterranean climate. Agronomists Aguilera et al. show that organig farming techniques such as cover cropping and pruning mulching should offset greenhouse gas emissions, thus leading to carbon neutral crop products.
