Praktijkworkshop: 11 maart 2016: Opening in verdichte bodems (Dutch)

Bruisend bodemleven: opening in verdichte bodems

  • Locatie: 11 maart 2016, Aardehuis, Olst
  • Door Fransjan de Waard en Ruben Borge

Het leven in de bodem is onmisbaar, onschatbaar – en nog vrijwel onbekend. Ook voor mensen die met de bodem werken, zoals boeren, groenbeheerders en hobbytuinders.IMG_20151029_110404

Nieuw is ook dat een boost voor het bodemleven cruciaal is in de aanpak van bodemverdichting.

Een ‘grondig’ probleem dat veel beter voorkomen kan worden, maar dat met de klimaatverandering zeker nog verder zal groeien. In de workshop “BRUISEND BODEMLEVEN: opening in verdichte bodems” draait het om de principes èn de praktijk. Deelnemers worden meegenomen in de aftrap van een integrale oplossing voor de verslemping en wateroverlast op de zware kleigrond ter plekke.

Life is back

Only one month after soil aeration in Raerd with the Evers plow, we find new signs of life are visible in the soil more root growth, earth worms, insects. We also see the effects of their work in the channels they leave in the soil. Soil drains better now

How we made it:

  1. Visual soil Assessment. This gave us an idea about what were the key constraints that affected the gras production. Heavy clay soils of Raerd need to be managed to allow root forming and avoid soil compaction.
  2. Assess the land and water management. We saw that with the current land management, the soil will tend to compact and create an environment with little air and water exchange. This environment would  stress the root and compromise the grass production.
  3. Designed a new fertility plan that include building soil structure in permanent grassland with structural help of the vertical plow. This use will compensate the imbalances of the use of machinery. Once the right soil conditions are created to allow successful biological settlement and nutrient cycle.



Where the t(r)ees go green

During the construction of the Dirkshorn golf club the soil got destroyed by heavy machinery. After their work, engineers and bulldozers left a inert substrate where plants and especially had difficulties to grow.

Trees and shrubs are very important part of the course because they mark the field that players have to follow. After the first season more than half of the planted trees died or suffered severe damage. Supporting those trees with chemical fertilizers was not feasible. On the other hand a golf court generates a tremendous amount of green waste that need to be disposed. Getting rid of this waste is a cost.

Rockin Soils assists the the golf club and Grondmij, the company in charge of maintenance, to produce organic fertilizers from the organic waste to feed the young trees. Self made solid and liquid fertilizers inject indigenous forest life in the soils, improve their structure, re-mineralize them and restore the ecosystem that supports the settlement of the trees.

The pilots started in April 2013. From august 2013 until September 2013, the trees received three applications. Several tests are also carried out on grass of greens and tees. Results of the pilot are expected in the spring of 2014.
