Soil-Improving Cropping Systems selected for testing in Study Sites

 

 Study site  Short-listed SICS Comments
 Belgium  1.Application of different types of organic fertilizers: wood chips, cut and carry fertilizers, bokashi, compared to compost and solid manure.
2.Maize: undersown with grass, strip-till in existing grassland, ordinary strip till compared to conventional tillage.
3.Precision farming: site-specific application of compost and or wood chips; field scan (pH, OM content) before and after the trial, yield mapping.
4.Controlled traffic: implemented in at least one field, measurements of soil characteristics, crop growth and yield in and outside the roadways.
5.Novel crops: perennial cereals (if seeds are available) and soya, in at least one field, measurement of soil and crop characteristics and yield potential (in comparison with traditional crops).
Scientific trials (with layout of treatments and replications, execution of measurements and observations)
 Norway  1. Precision agriculture
2. Biological compaction release
3. Cover crops
Demonstration trials (with execution of measurements and observations)
 Hungary  1. Leguminous crops
2. Farmyard manure
3. Crop rotation
 
 Switzerland  No single system chosen, but likely to be controlled traffic (comparison of a plot where limiting compression by weight is applied, with plot without limiting compression), green manure or the Controlled Uptake Long Term Ammonium Nutrition
system
Measures will need to be looked at in suitable combinations and will depend on location of field trials chosen, experimental set up and monitoring
 Denmark

 1.Ploughing contra no ploughing systems

 

 

2.Row (Alley) cropping systems

 

 

3.Crop rotations with and without grass / Clover (with grass varying amounts of grass and other crops); technologies for row/alley cropping "micro- rotations"

4.Liming experiments (long term effects of dose

 

5.Long term effects of manure and fertilizer practices

 

6. Lap and trial

Less ploughing is also demonstrated in the row cropping experiment at Samsø (with Gunnar Mikkelsen), where strips of green manure clover grass is not ploughed.

Tested/demonstrated at the farm of Anders Lund where the cereals are sown in rows, and at Samsø (with Gunnar Mikkelsen), where strips of green manure clover grass is not ploughed. Moreover we have row cropping experiments at the AU Field Station in Foulum.

 

 

 

As at the long term experiments at St. Jyndevad

As in the long term experiments at Askov. Moreover the fields with Gunnar Mikkelsen/ Samsø is fertilized with compost recycled from urban areas)

The whole island of Samsø as a full scale demonstration lap and trial, via scenarios and impacts assessments of possible soilcaring transitions of the farming in the island
