Real cases in Spain

Behind every farm there is a family, a team or a cooperative. One day they decided to care for their soil differently. Only those who let us use their name appear here. And we only tell what they already tell.

Some of them you can watch on video, on their own farm.

Named

Projects we accompany

Farms with their own names. Visit their websites and see for yourself. If your farm looks like one of these, the next step is your own diagnosis, not copying your neighbour’s.

To everyone who trusts this project

Thank you to every farmer, livestock keeper and family who opens their farm to us. Thank you to the teams and people who learn with us. And thank you to everyone who collaborates on and supports this work. Your trust is what makes soil, water and food genuinely better.

Among those who collaborate with us is CoCo Sapiens.

Thanks also to Iggy Love for the images and drone videos that show our farms.

La RiojaMarket garden

Huerta de Tormantos

La Rioja · 2019-2020, before True Regenerative was founded: Xavier Vélez coordinated the farm’s transition. According to the December 2019 soil analysis, the soil started at 2.5 % organic matter, pH 7.3 and a magnesium deficit. A farm lab was set up in a storehouse: 600 litres of biofertiliser in November, scaled up to 5,000 litres in January. With a professional topographic survey, a keyline layout was drawn for a 2.66 ha plot and worked with a rented Yeomans plough. The bokashi, made with local materials, reached 50 °C within 48 hours and was applied at about 10 t/ha. In the following months spontaneous plants slowly returned; pH remained the main limiting factor. Website: huertadetormantos.es.

Rice + ducks · real regeneration

Symbiosis between rice and ducks

Ebro DeltaRice & ducks

EcoCastells

Ebro Delta · 2022-2023: Xavier Vélez, as the company’s in-house head of regenerative agriculture. Organic rice that had been losing yield to weeds for years, without herbicides. In November 2022 compost was spread on 14.8 ha; in the 2023 season, home-made bokashi went onto eight fields (5 to 6.7 t/ha) and mineral brews onto three of them. With all permits in place, a small duck unit was set up to graze 1.5 ha of paddy. In a check on 7 August 2023, plants from the field with ducks had more tillers and longer roots than those from two neighbouring fields sown the same day: a one-off observation, not a trial. Website: ecocastells.com (Instagram). Also at the Regen Hub (LinkedIn) and in a post listing rice with ducks among climate and nature solutions (LinkedIn).

Camarles (Baix Ebre)Greenhouse vegetables

L’Horta de Carme

Camarles (Baix Ebre), in the Ebro Delta · a family business that switched to organic production in 2005; today it farms 55 ha of vegetables and fruit trees, with its own warehouse and packing room, under CCPAE control. The challenge: go one step further and regenerate the greenhouse soil. What we do: intensive soil regeneration with biofertilisers, rock dust and biochar, plus a Venturi injector for drip fertigation. In the greenhouses we are running a field trial with doses of up to 100 t/ha of bokashi to see how the soil responds. Below, the greenhouse at planting and with the tomato plants grown; the work is ongoing. Website: lhortadecarme.cat.

Tugas Pagès

Baix Llobregat (Viladecans) · about 10 ha of vegetables, moving from organic to regenerative: soil regeneration and biodiversity, focused on fertility and independence (community biofactory with Sostenipra and Ecocentral).

Berja (Almería)Biostimulants

EBE Bionatur

Berja (Almería) · 2021-2022, before True Regenerative was founded: Xavier Vélez was transition coordinator and R&D lead at Eco Bionatur SL, a small company that makes organic fertilisers and biostimulants. He took part in developing a liquid fertiliser with plant extracts, leonardite, minerals and microorganisms, designed for vegetable greenhouses. We have no publishable trials from that period. Later, in 2024-2025, the company commissioned the Miguel Hernández University to run an agronomic efficacy trial of its EBE BIONATUR SR+ biostimulant on tomato, lettuce and pepper; it was a project between the company and the university, without True Regenerative, and we have found no published results. The line is still active at ecobionatur.es (Instagram).

They say it, not us. Every quote links to its source.

«Xavier, a young technical adviser specialising in regenerative agriculture and a committed farmer too, is an example for the sector and reminds us that sometimes the big players also learn from the small ones.»

From farm to table

A real sales channel for a farm we support: EcoCastells ducks, from the rice paddy to the kitchen.

«Enjoy this great EcoCastells regenerative livestock project with pastured ducks in the Ebro Delta [...] A perfect symbiosis that closes its cycle in the kitchen of l’Antic Molí and Vicent Guimerà, championing healthy food that cares for aquatic ecosystems and biodiversity.»
Original: «Disfruta de este proyectazo de EcoCastells de Ganadería Regenerativa con patos pastoreados en el Delta del Ebre [...] Una perfecta simbiosis que cierra su ciclo en la cocina de l’Antic Molí y Vicent Guimerà, poniendo en valor una alimentación saludable y que cuida los ecosistemas acuáticos y la biodiversidad.»

In the video, the Association explains the project’s approach (this is their explanation, not a measured result):
- The ducks help to manage the weeds.
- They add fertility to the rice fields.
- They feed on apple snails and insects.
