  6. Beaulieu farm • Traditional orchard : used by teachers for educational reasons • Wintering of an experimental apiary • Study of the impact of the corn seeds treated with Cruiser on bees.

  7. Castagnère farm • Barran Village(10 km from Beaulieu) • The farm was taken over in 1999 • Crops in conventional agriculture • 90 ha of areas used for agriculture (AUA) • Rotation of the crops: wheat – sunflower – oil seed rape • No watering since 2004

  8. Castagnère Farm • 2007 : 9 ha of agroforestery • experimental programme « water and biodiversity » Oak 52 Ash 49 Maple 44 Pear 44 Lime 26 Walnut 22 Wild cherry 23 Apple tree 18 Chestnut 17

  9. La Hourre Farm • La Hourre farm (Auch) : • Organic crops • The farm was taken over in 1999 • 55 ha of TCA (Total Cultivated Area) • 2 years of conversion into organic farming • Partner : C.R.E.A.B (Organic Research Center) in Midi Pyrénées for experimenting and the following up of the crops

  10. La Hourre farm • The CREAB Midi-Pyrénées : The Chamber of Agriculture of Midi Pyrénées A group of organic producers from Midi-pyrénées Technical Institute Economic entity

  11. Hilly area = low water resources Deep soil = high water resources

  12. La Hourre farm • The rotation of crops set up at La Hourre : • 1 short rotation : • On deep soils (2 plots) • rotation : soya and wheat • crops for human consumption = economic aim • 1 long rotation : • 3 to 5 years • Legume species between two crops

  13. Legumes (field beans, peas, lentils) Straw cereals (winter wheat) Cereals (winter barley) Purple clover under the cover of wheat at the stage ear 1 cm. Optional fallow 1 year Optional fallow 1 year with purple clover Sunflower La Hourre farm • Rotations set up at La Hourre : • Example of a long rotation :

  14. La Hourre farm • Weed control : a key point in organic farming

  15. Preventive Curative La Hourre farm • Weed control : a key point in organic farming • Rotation of summer and winter crops • Deep ploughing • Many passages of stubble-plough ( sowing) • Harrowing on all the cultures (50% uprooting / 50% covering up) • Hoeing machine

  16. « La Hourre » farm • Weed control : a key point in organic farming • Despite these efforts, apparition of thistle circles on the site • Weed control  implantation of meadow (lucerne : for 3 years) • Implantation : Sowing under the layer of winter barley in weak density (90-100 kg/ha) • Possible development of organic lucerne

  17. La Hourre farm • Results obtained :

  18. La Hourre farm • Organic farming has made a great contribution to the development of traditionnal farming : • Reasonable use of fertilizers • Development of the « mock sowing » • Use of mechanical weeding (sunflower/corn)
