1. Strip-Till Introduction
1. Strip-Till Introduction
1. Strip-Till introduction
• Strip-Till was developed around
1990 by American farmers
• Strip-Till is an advancement of
the direct-drilling system
• Cold and wet soils are not
suited for direct drilling of
maize
• Solution was here to till only
the soil under the plant-rows
• Use in the US mainly for maize
after maize or after soya
• The stripes are mainly formed
in the autumn
1. Strip-Till introduction
• Around the year 2000 strip-till swopped
over to Europe
• Strip-Till is here seen as a further
development of the conservational tillage
• In Europe, we are talking about different
cultures to drill after strip-till
• Also the conditions are different (strawyields, intermediate crops, …)
• Small row-widths (sugar-beets) are not
easy to suite with US strip-till machines
1. Strip-Till introduction
Possible cultures:
•
•
•
•
•
•
•
•
•
Maize
Sugar-beets
Oilseed-rape
Sunflower
Horse beans
Sorghum
Soya
Vegetables (cabbage)
(Cereals)
2. Tillage
In the classic Strip-Till system there are only two
operations possible to establish a crop:
1. Tilling the stripes
2. Seeding with a precision seeder
2. Tillage
In Europe the so called intensive Strip-Till was
developed:
1. Shallow stubble-cultivation
2. Tilling the stripes
3. Seeding with a precision seeder

2. Tillage
In the US most of the stripes will be tilled in the
autumn, to get a seedbed prepared by frost
this could be also a solution for heavy soils
2. Tillage
In Europe is it possible to till the stripes on light to
medium soils in spring-time!
2. Tillage
GPS-guidance of the tractor is a critical part of the StripTill system
RTK-systems (+/- 2 cm) can
guide the tractor with high
precision
Normal GPS-systems (+/- 15) without
RTK must be overridden by hand, but
sometimes you don’t get the needed
precision
2. Tillage
GPS-guidance of the tractor is a critical part of the StripTill system
But anyway the best way is to have the
working widths of the strip-till unit and of
the seeder identically or maximum twice
3. Pros for the soil and the plants
• the dark surface of the stripe enables the sun to warm up the soil much
quicker
• The loosened soil leads to air-circulation
• Thanks to the air-circulation, the soil can dry and warm up
• This is very important for cultures like sugar-beet and maize
• Big advantage in comparison to direct drilling
3. Pros for the soil and the plants
Hermann, 2013
• Pictures of two trials in Germany after 8 mm of
rain falling down in 15 minutes
• The soil in the left conservational-trial was not
able to infiltrate the water
• Thanks to the natural soil structure in the interrow area, the rain could be infiltrated and stored

3. Pros for the soil and the plants
Strip-Till
conservational
• Undisturbed areas in the inter-row can save moisture in the soil
and do not dry out so fast
• Plant-residues or straw on the surface protect the soil for
unproductive drying out
3. Pros for the soil and the plants
Changed weed control management
In the non-cultivated areas
between the rows no weedseeds, out of former years can
come up to the surface
Residues and straw on the
surface enable light-seeds to
emerge
20
3. Pros for the soil and the plants
• Energy-saving by only tilling the areas, where afterwards the plants will
grow
• At 75 cm row-spacing there will be only 30 % of the soil moved
• At 45 cm row-spacing there will be only 50 % of the soil moved
• on top you can save time, due to one-pass operation for seedbed
preparation
You can reach the same yields like in full width-cultivation with
less soil preparation

Lummer, 2011
You can reach the same yields like in full width-cultivation with
less soil preparation
3. Pros for the soil and the plants
New options for fertilizer management!
• Placing the fertilizer in one pass together with the tillage
saves field passes
• The fertilizer is directly located, where the plants it needed
and the fertilizer can be absorbed much quicker
• New fertilizer options for oilseed-rape and sugar-beet, but also
advantages in maize, cause of a boost in root-development
3. Pros for the soil and the plants
New options for fertilizer management!
• Incorporation of slurry by building up the
stripes
• Saving of additional working-passes
(incorporation with cultivator)
• Compliance with European laws
• Important in this fact is the precise
distance between the seed and the slurry
• The maximum amount of slurry has to be
considered (25 m³ )
• Not every slurry-tanker is able to use a
strip-till unit (pulling-force)
3. Pros for the soil and the plants
New options for fertilizer management!
Talking about slurry-injection, we have to use Piadin to
stabilize the Ammonium!
Laurenz, 2012
4. Risks and cons
Erosion is also in Strip-Till possible!
The stripes has to be made perpendicular to the
slope.
4. Risks and cons
GPS-systems
• GPS-systems are not
everywhere common
• Prices for such systems are
declining at the moment
• Bad connection can lead to
breakdowns of the guidancesystem
• Driftage on sloped fields has to
be corrected by the GPSsystem, especially by trailed
machines
4. Risks and cons
4. Risks and cons
traffic-lanes
Strip-Till units are not
subsoilers, because of this
traffic-lanes in the field are a
problem with no real solution
at the moment.
Controlled traffic could be a
solution.
4. Risks and cons
In all cultivation systems with reduced tillage-activities,
slugs are a problem.
But this is also a problem of management!
4. Risks and cons
Mice
• Mice are using the loosen
stripe to built up their burrows
• The mechanical control is not
ensured
• The Stripes must be free of air
pockets (wings at the share)
• New ways of management has
to be found

7. Field tests 2013
• Working with the Kultistrip in the autumn time for spring seeding of sugar
beets
• Directly working in 30 – 40 cm high green mustard

RTK
• Better conditions in the stripes, made in spring-time (left picture)
• Not enough frost over winter to break the clods in the old stripes
• Sugar-beat-plants one month after seeding
• Preparing stripes for maize after stubble cultivation (intensive strip-till)
• The farmer had a few days before put slurry on this field and worked it in with a
short disc harrow
• Working-depth 25 cm and –speed about 10 km/h
• Maize has grown exactly than in conservational tillage
• The barley has reemerged, because it was not killed chemically
• Maize is standing in a clean stripe
• Making stripes directly into field grass for maize
• The machine worked very well and prepared a nearly perfect seedbed
• The grass was killed chemically some hours before working with the prototype
•

•
Planting maize in the stripes on the 3rd of may
John Deere AutoTrac with SF 2 standard
The trailed optima followed very good the stripes, cause of the loosened soil
High moisture level around the seed
• Three weeks later maize is in rows
• Field grass is dead, but still there as a protection
• Same plant-development by strip-till and conservational tillage, but one
pass strip-till vs. 4 passes in conservational
Strip-Till
Conservational
Tillage

• Stripes made with the Kultistrip in the area of
Soest
• Direct working in the rye-stubble
• The field was harvested for silage one day before
• 4 years old field grass
• Soil with high percentage of clay
• Two passes with the Kultistrip were needed
to prepare the stripes
• Strip-till for oilseed-rape with 45 cm row-spacing

•
•
Preparing stripes for sugar beet in loamy-sandy conditions
Intermediate crop with different plants like flax or mustard
Working depth of 25 cm and a speed of 9-10 km/h
Fertilizer placement (DAP) at a depth of 12 cm
40 ha in total at this place
• Residues in the inter-row area are
completely conserved
• Good protection against winderosion in this area
• Very uniform plant development
• No problem with compacted zones
on the headlands
• Plants have overcome very good a
dry period of 2 weeks
• Very good beet-body 2,5 months after
preparing the stripes
• Long main-root because of not
compacted seedbed
• Fertilizer depot leads the roots faster
into the deep
• More moisture in the underground
helps the plant to use the nutrients
• Big Trial for sugar-beet in Strip-Till together with the agricultural
chamber Soest
• Comparison of different working depth (10, 18 and 25 cm) for preparing
stripes in spring and also comparison to conservational tillage
• Plots with fertilizer (DAP 10 cm depth) and without
• Second year of testing, yellow mustard as intermediate crop
• Wet conditions by cultivation
shallow working-depth was better
• Seeding of the sugar beets at the 4th of April
• Guidance with RTK accuracy
• Mulch-seeding equipment at the Unicorn
row produced some more fine-earth around
the seed
• Very good emerge of the sugar beets in all plots
• Plants in the deep cultivated plots are a little bit slower than the others
Deep cultivation (25 cm)
• 2. control at the 12.06.2014 with no different
between the plots at the leaves
• BUT if you look at the beet itself there is a
difference between shallow and deep cultivation
Shallow cultivation (10 cm)
•
•
•
•
Strip-Till for maize close to Soest
No intermediate crop, just shallow cultivation after barley harvest
Weeds and re-emerged barley was killed chemically
Good conditions for Kultistrip and as well Optima
very uniform plants in all areas
of the field even in the
headlands
residues in the inter-row is
dead and covers the soil

Maize after maize on a very heavy soil in the area of Beckum (Germany)
Second year of Strip-Till (see trials from 2013)
We tested the cage- and Farmflex-roller, better drying with the cage-roller
Seed-bed was better than 2013 but still very rough
We moved the strip 30 cm over so that the old stubbles are in the middle of
the new stripes
• Very uniform plants here only in the compacted headlands some problems,
due to the wet harvest in autumn
• The farmer will bring out slurry in the standing plants
• Big test for maize in Strip-Till on the island Fehmarn (Germany)
• Very heavy soil, but with high yields (12 t of wheat in average)
• Crop before was wheat and then there had been different cultivations:






4x straw harrow
3x straw harrow + 1x short disc harrow
3x straw harrow + 1x cultivator
2x straw harrow + 1x short disc harrow + 1x cultivator
1x straw harrow + 2x short disc harrow + 1x cultivator
1x straw harrow + 2x cultivator
• Comparison between Strip-Till with different cultivation before and two
different kinds of conservational tillage
• Every plot is divided in two parts where we are testing if phosphorus can be
changed with potassium in the fertilizer depot
• Special aim of the pre-cultivation is to fight against black-grass
• All the plots had been rolled after seeding
• Very good emerging of the maize, no visible difference between the plots
• Faster growing of the maize in the plots with intensive pre-cultivation, due
to soil-temperature (only one day between Kultistrip and Optima)
• Better start for the plant, which had a phosphorus fertilizer depot
