(Dutch) 5e dag Kwantum landbouw: de bodem, breed bekeken, in Broekland

Cursusdag Kwantum landbouw: De bodem, breed bekeken (ook voor niet cursisten toegankelijk)

 Stichting Gaia Sira organiseert op 21 april een bijzondere dag over de bodem die ook voor niet-cursisten toegankelijk is

Op 21 april zullen Gino Smeulders en Rubén Borge ons meenemen langs verschillende bodemaspecten waar u niet zo vaak over hoort. Weet u dat paramagnetisme een grote rol kan spelen in de wortelontwikkeling en dus opbrengst  van planten? Met proeven gaan we hiernaar kijken.

Ook zullen we een fermentatiemengsel maken om de bodem te voeden en nog beter te werken.

Voorlopig programma:

– Inloop met koffie- een bezoek aan het bedrijf

– de bodem voelen op een of andere wijze met bodemprofiel bekijken en energie voelen van bodemmonsters

– een inleiding door Gino Smeulders, biogeoloog , o.a. over gesteentemeel en diamagnetisme van de bodem

– een inleiding door Gino Smeulders, biogeoloog o.a. over gesteentemeel, over paramagnetische en diamagnetische gesteenten en over het bodemleven- een fermentatiemengsel maken met Ruben Borge

Locatie: Broekland

Kosten: euro 121 (incl btw) per dag inclusief lunch; euro 30 (incl btw) minima.

Course series: Farmer’s life (boerenleven)

Last month we started the 2017 edition of the course “farmer’s life” (in Dutch Boerenleven). Farmers from different areas of the country gather together, each time in a different farm to talk about healthy production systems. They get new insights in key issues for their farms from different experts and they learn from each others experience too.

The course series aims to give farmers practical state of the are low investment/ high return tools for their Dairy farms.During different journeys, we work with farmers around the management of complex systems of the Dutch dairy farms. All from the basis of low external input.

Each journey focus on one specific issue and visit a different farm. The we give the courses in context of the participants.

  • Farm Maganement (by Frens Schuring)
  • Soil life and DIY diagnoses (by Ruben Borge)
  • Low external organic inputs for the Dutch farm (by Ruben Borge)
  • Soil Analysis Bioelectonics  (by Peter van Hof)
  • Mineral cycling  (by Anton Nichten)
  • Grass land management and mob grazing (by Peter Takkens)

This course series is co-organized by Ria Commandeur and  Peter Takkens.

With Ragmans Farm UK at ORFC 2017

In January 2017…Oxford Real Farmers Conference (UK)

I feel fortunate to sit with Matt Dunwell and Juanfran Lopez  of Ragmans Farm on 4/ 5th January 2017 in Oxford at the ORFC and share our experiences about our work  with bio-fertilizers. For the last two seasons, Juanfran and Matt have been doing very interesting work  with bio-fertilizers in UK in apple trees and vegetables. I have been working with bio-fertilizers in different crops, soils, climates and cultures of  the world.

Putting  our experiences together is an exciting experience worth to be shared with the Real Farmers community.

Besides the presentation, we will combine technique and humor to demonstrate the simplicity (and beauty) of this technology by preparing bio-fertilizers, dressed like real chefs. Want to see it?

  • When: 4 january 2017
  • Where: Oxford, UK

Rockin Soils was in October 2016 in Nicaragua to assist the Union of Cooperatives COSATIN with the optimization of organic fertilizers. To assess raw materials, improve the production process and optimize the quality control system to increase the quality of the organic fertilizers.

Growing organic Coffee in Nicaragua, between 700 and 1000m altitude is challenging. Sometimes it does not rain in months and suddenly a storm can leave easily 20 mm in few hours. This erratic tropical weather is often worsen by periodic events like “el niño”. With all these extreme events, the  fragile volcanic soils struggle to keep in shape.

The Farmers of Boaco rely on coffee, ginger and turmeric as main cash crops and they also grow many other fruits and vegetables for own consumption. Farmers know best how to make compost though they find difficult to access to raw materials and often do not get the time/space to produce it. They rather buy it from somebody they trust.

This reliable compost provider in Boaco is the Farmers Union Tierra Nueva. Tierra Nueva is well known in the country for their good quality organic coffee. It is an impressive good coffee that grows at less than 1000m of altitude.

Their organic coffee is sold in small scale shops over the whole country under the brand Lo Sano.  Actually a lot of their coffee is reaching European shops. Looking ahead in the future, the Union decided to cover the demand for affordable top quality organic fertilizers. Few years ago they started a composting project. Now they have a composting plant and will be able to provide with organic fertilizer to hundreds of farmers of the area.
