2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
This technique can be applied in any crop rotation or soil. Tillage of the soils is done with special machines that do not turn over the soil (non-inversion), and the tillage depth can be more shallow than with conventional tillage (ploughing).
2.2 Detailed description of the Technology
This technology is applied in Vredepeel (the Netherlands) on a sandy soil on arable fields. The technology is not by environment limited to these conditions, it could for example be applied on clay soils as well. It is applicable for various crop types. The main point of this technology is the specific machine that is used to do the tillage. The machine is called a rigid-tine cultivator. The machine can be purchased for a few thousand Euros, but in the Netherlands it is also possible to let a contractor do this tillage. The average tillage depth here is around 25 cm, dependent on the crops in the rotation. The purpose of the shallow non-inversion tillage is to keep the soil organic matter in the topsoil, and to disturb the soil as little as possible, which has as benefit that the organic matter levels in the topsoil can increase and soil life is maintained better. Overall, the soil structure in the topsoil will improve. This is also what the land users like about using the non-inversion tillage. The yields when using non-inversion tillage are similar to the yields of ploughed fields. The difficulty of this technology is the control of weeds, since the topsoil is not turned over, small weeds and seeds are not buried, and have a higher change to survive. This may make that more pesticide is used to control the weeds than when you plough the soil, therefore this tillage technique is less favorable amongst organic farmers. Also when grasses are a (large) part of the crop rotation non-inversion tillage might not be the best solution, since it is harder to destroy the grass when preparing the soil for the next crop.

|Total costs for establishment of the Technology in USD||2298.85|
4.5 Maintenance/ recurrent activities
|1.||destruction of cover crops after winter||once per year|
|2.||one additional tillage operation instead of ploughing||once per year|
the described operations are the changes compared to conventional tillage which is ploughing
4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)
There are no additional costs for inputs compared to conventional tillage (ploughing in spring). There might be a minor reduction of fuel costs because the ploughing of a field takes more fuel, but on the other hand it is sometimes needed to cultivate the land an extra time, because you cannot destroy the winter crop/green manure at once. So in the end it will be around the same.
4.7 Most important factors affecting the costs
Describe the most determinate factors affecting the costs:
The investment costs for adapted machinery are the main factors affecting costs.

The fields with non-inversion tillage and conventional ploughing are right next to each other, and with the same crops, no effects on crop quality were found.
Income and costs
expenses on agricultural inputs
More shallow tillage needs less power from the machines, but on the other hand more tillage operations to destroy the crop.
Water cycle/ runoff
Since the soil structure will improve, the infiltration capacity of the soil also improves.
soil organic matter/ below ground C
Expectations are that soil organic matter content in the (top) soil will increase, but so far no significant results were found on that.
