Chile: Biodynamic production of blueberries in the spotlight

The biodynamic plantation of blueberries at Matetic Farms, near Casablanca, in the region of Valparaiso, has caught the eye of the External Advisory Council (CAE) of INIA La Cruz.

Dr. Lorenzo Pastrana, of the Iberian International Nanotechnology Laboratory (INL), visited this certified blueberry sustainable garden; a fertile place, abundant in fruit and full of vegetation where all agronomic practices are designed to respect the environment.

This garden faithfully complies with the Demeter standard, an international body that certifies biodynamic agriculture. No pesticides, herbicides, or chemical fertilizers are allowed here.

They apply all of the basics of biodynamic agriculture. For example, the agronomic management of the garden follows a work schedule according to the seasons, moon and sun cycles so there are certain days that are more appropriate to perform certain management tasks (fruit, leaf, flowers or root) as everything influences how the plants grow. They also make Biodynamic preparations, use compost to ensure high soil fertility, and meet all the needs of organic and biodynamic production.

The project incorporates biodiversity through the use of plant coverings with grass, leguminous, turnip, and mustard plantings, among other species, which are maintained as a permanent cover between the rows of blueberries.

According to Cristian Gwinner, these plant coverings on this biodynamic system "have added organic matter to the soil, providing it with significant amounts of nitrogen, improving the soil's quality and contributing to the formation of humus."

To control scales, conchuela, red spider, and thrips they have mainly released Cryptolaemus, Rhizobium, and Chrysopas, which have remained in the environment as a biogical control.
