The Life-Polyfarming regenerative agriculture project, coordinated by Planeses and CREAF, has recently published six videos in which they explain, in an informative tone, the agricultural and livestock techniques carried out in the pilot farm in La Garrotxa, Catalonia. These techniques aim to recover fertile and profitable soil in a way that respects the environment.
Mobile pens to manage chickens and rabbits
The animals are moved every day using a system of fences and mobile shelters. Thus, they enjoy clean pastureland every day while enriching the soil with their excrement.
Management of cattle through programmed intensive grazing
The cows graze each day on a different plot, and it takes around 50-60 days to return to an area where they have already eaten. In this way, they don’t have the chance to eat the regrowth from the first plants they ate, but they improve the fertility of the soil with their excrements.
Biofertilisers from microorganisms on the forest floor
Biofertilisers are highly nutritious liquid fertilisers for plants. In the Polyfarming system, they are made from the forest floor’s microorganisms dissolved in water enriched with milk, molasses, and minerals. You can discover the complete ‘recipe’ and its benefits by watching the video.
The BRF ’emulates’ forest humus
The Bois Raméal Fragmenté (BRF), or Ramial Chipped Wood, consists of the chipping of small branches. Once crushed, they are left to decompose for a time in the woods to obtain humus similar to the forest. When applied to the orchard or fruit trees, it improves the structure and water retention capacity of the soil.
Biochar, an ally to improve the physical properties of the soil
Biochar is the name given to charcoal when obtained from the pyrolysis of the biomass of plant origin. It has high organic content; it is very resistant to degradation, and it has high micro and mesoporosity. These characteristics allow the soil to retain more water, nutrients, and microorganisms.
Burying logs and branches under the ground increases the reserve of water and microorganisms
The cultivation over wooden beds, known as HügelKultur, consists of burying logs of various sizes in trenches under vegetable gardens and fruit orchards. Those remains act as a sponge to ‘store’ the water and microorganisms.
