Project research on growing trichocereus in syntropic systems (regenerative agroforestry )


Objective :

-reducing importacion of trichocereus from south america

-establishing a diverse genetic bank of pachanois, bridgesii and hybrids (over 30 different varieties)

-production of food

-production of aromatic plants and fowers for perfumery



DESIGN

Long term species (climax):

-A trichocereus seedling (2-4 years old). Selected crosses from new zealand (guru, dino, decosta, notch...) and from portugal.

-almonds

-oaks

- Damask Rose (end of lines)

Support : prickly pears (condensator of air moisture / chop and drop)



Medium term for both production & support (secundaries)


Rosemary

Lavender

Sages (white sage, officinalis & more)

elaeagnus

Acacia (acuminata, maidenii, longifolia)





Short term (placenta)


Production: pumpkins

Support : Sunflower (VERY IMPORTANT, gives shade from the midday sun the first summer. The cactus really appreciate!) , cruciferas, mostards, and a mix of random seeds of a bit everything.



Implementation :

80m long line, running east-west, with one drip irrigation

Middle line : cactus every 30 cm (240 tricho in total)

Interplanted with the almonds, acacias and oaks (every 4 m or so)

Front line : Prickly pears, aromatics , sunflowers

back line : pumpkins





Workflow :

-cut existing veggetation and keep the biomass aside

-Looseing of the soil over 1.20m wide

-Concentrating top soil in the middle

-integrating manure (300L)



-Planting of all the seedlings

-Adding the support species & the seeds

-Using all the biomass of the area and place it along the line. Then mulching with woodchips (1500 liter) – this is an important step to reduce the amount of grass coming back.

Worktime : 4 days with 2 people



Maintenance :

weeding the grass, thinning the sunflowers (probably keeping one every 30 cm), managing the ground covers to give space to the young aromatics...

->1h every 2 weeks (without counting the time standing there in contemplation... I prefer not to say how much this is)


ps: can't find a way to put the image in the correct orientation :/
