How does strip-till seeding of rapeseed and maize cut costs?
Strip-till seeding of rapeseed and maize lowers the costs of running a farm by combining deep loosening, sub-soil fertilisation and precise seeding in a single working pass. In this article you will learn how reducing the number of field operations makes it possible to cut fuel use by up to 50% and significantly shorten the time needed to work a hectare. Instead of struggling with rising fertiliser prices, water shortages and closing agrotechnical windows, you gain yield stability and full control over your budget. Based on the practice from our 750-hectare test farm, we present proven Czajkowski Maszyny equipment solutions that raise crop profitability without quality compromises.
Why does strip-till seeding of rapeseed and maize cut costs?
Strip seeding of rapeseed and maize lowers financial outlays by limiting the number of agrotechnical operations to a single pass and by precisely metering fertiliser directly beneath the seed rows. Conventional cultivation requires separate ploughing, cultivating, spreading fertiliser and seeding, which multiplies spending on diesel and machine depreciation. The strip system loosens only 33% of the field surface, which limits water evaporation from the soil and reduces the tractor power required. Involving fewer workers and machines makes it easier to complete work within tight weather windows. The team building the Czajkowski Maszyny brand verifies these savings in daily farming practice.
Fewer passes and fuel savings per hectare
Replacing ploughs and tillage units with a strip-till machine reduces fuel consumption by 40-50% per hectare. With conventional ploughing, total diesel use averages 35-45 litres per hectare, whereas a pass with a strip unit requires about 15-20 litres. Reducing the number of field passes also saves the tractor operator's working time by up to 60%. Fewer tractor engine hours translate into a slower drop in machine value and lower costs of service and fluid changes.
Precise sub-soil fertilisation beneath the seed rows
Precise fertilisation of rapeseed and maize in strip-till consists of placing fertiliser granules in the loosened strip of soil exactly beneath the seeding line. Depositing fertiliser at two depths (e.g. 10 cm and 20 cm) ensures nutrient availability in the early and later stages of root-system growth. This method of application prevents fertilising weeds in the inter-rows, which makes it possible to reduce mineral fertiliser doses by 15-20% without the risk of yield loss. Fertiliser enclosed underground does not volatilise or wash out during intense rainfall.
How to correctly seed rapeseed using the strip-till method?
Correct strip-till seeding of rapeseed requires thorough soil preparation after the preceding crop, maintaining the right depth of strip loosening and an even distribution of seeds in the row. A key element is the clean removal of crop residues from the seeding zone with the cleaning stars of the working section. A properly performed operation creates ideal conditions for the seeds to draw up moisture and quickly build a taproot system. We describe detailed agrotechnical recommendations and practical experiences with this crop in the section on rapeseed cultivation. The even pressure of the firming wheels eliminates air pockets around the seed, speeding up emergence by 2-3 days.
Rapeseed seeding rate and optimal seeding depth
The optimal rapeseed seeding rate in strip cultivation is 35 to 45 seeds per square metre, and the recommended depth parameter is 1.5 to 2.5 cm. The lower seeding rate compared with conventional ploughing results from the very high emergence rate in a well-prepared strip of soil. Placing the fine rapeseed seeds too deep weakens germination vigour and prolongs the time for seedlings to reach the surface. Precise depth control by independent seeding sections prevents uneven plant emergence.
Is it worth disc-harrowing before seeding rapeseed?
Disc-harrowing before strip-till seeding of rapeseed is recommended only when a large mass of straw remains on the field or there are deep ruts after harvesting the preceding crop. A shallow pass with a disc harrow to a depth of 3-5 cm stimulates weeds and cereal volunteers to germinate, making it easier to destroy them later. If the field after the combine is even and the straw is well chopped, the strip unit will handle direct seeding without additional disc-harrowing. Skipping disc-harrowing saves another 8-12 litres of fuel per hectare and protects residual soil moisture.
Strip cultivation of maize - seeding date and row spacing
The date for seeding maize in strip cultivation falls when the soil temperature reaches 8-10°C, which usually happens at the end of April. Strip soil treatment, however, means the darker, exposed strip of soil warms up faster in spring than soil after ploughing, which allows for earlier seeding - often as early as mid-April. Maize is grown in wide rows, occupying 13% of the field surface, while the remaining 87% is covered with mulch. Choosing the right date allows plants to make optimal use of spring moisture. You will find more details on the specifics and requirements of this plant in strip technology on the subpage dedicated to maize cultivation. The presence of mulch in the uncultivated inter-rows helps retain water, which effectively mitigates the effects of soil drought.
How does strip cultivation of maize affect yield?
Strip-till technology, thanks to deep loosening of the seed strip (up to 35 cm), ensures strong development of an individual plant's root system. The precise application of sub-soil fertiliser into the root zone makes its efficiency significantly higher. This allows fertiliser savings of around 30% without yield loss, and often even contributes to improving it compared with conventional cultivation. In addition, the intact inter-rows have higher soil bearing capacity, which facilitates later passes of heavy machinery during harvest without creating ruts.
Which seed drill for maize and rapeseed should you choose for strip-till?
A suitable seed drill for maize and rapeseed for strip-till technology should provide high pressing force of the working sections, smooth adjustment of loosening depth and accurate fertiliser distribution. Trouble-free operation in difficult field conditions and resistance to clogging with plant residues are of key importance. Choosing a machine matched to the farm's area structure determines the smooth course of the seeding campaign.

FAQ - Frequently asked questions
What row spacing is optimal when seeding maize with the strip-till method?
The optimal row spacing when seeding maize with the strip-till method is 75 cm in standard grain cultivation or 45-50 cm when seeding in narrowed inter-rows. The 75 cm spacing fits most combine headers and allows the development of maize's powerful root system. Narrowing the spacing to 45 cm speeds up canopy closure, reducing water evaporation from the soil and shading out weeds. Regardless of the spacing, strip units precisely deliver fertiliser beneath the axis of each row.
Does the rapeseed seeding rate in strip cultivation differ from conventional?
The rapeseed seeding rate in strip cultivation is 10-15% lower compared with conventional cultivation and averages 35-45 seeds per square metre. The lower seeding rate results from the exceptionally high branching capacity of plants in the loosened strip of soil and high emergence energy. The absence of crowding in the seed strip and the precise delivery of fertiliser stimulate the development of a thick root collar before winter. As a result, a lower plant stand gives a higher seed yield with better parameters.
How deep should the soil be loosened for seeding rapeseed with strip-till technology?
The soil for seeding rapeseed with strip-till technology should be loosened to a depth of 20 to 30 cm, depending on the compactness of the subsoil and the presence of a plough pan. Deep loosening of the strip allows the rapeseed taproot to percolate freely deeper into the soil profile in search of water and nutrients. At the same time, mineral fertiliser is applied at depths of 10-15 cm and 20-25 cm. The correct working depth of the loosening tine prevents deformation of rapeseed roots.
When is it best to seed maize in a strip cultivation system?
Maize should be seeded in a strip cultivation system when the soil temperature in the seed strip at a depth of 10 cm is at least 8-10°C. The strips of soil after a strip-till unit pass warm up faster than soil under full mulch in no-till, which allows a timely start of seeding. The optimal date in Polish conditions usually falls from mid-April to early May. Delivering starter fertiliser directly into the seed strip speeds up the early growth of seedlings even in a cooler spring.
Which starter fertilisers work best when seeding rapeseed and maize with strip-till at the same time?
When seeding rapeseed and maize with strip-till technology at the same time, multi-component granular fertilisers rich in phosphorus, nitrogen, potassium and sulphur work best. Phosphorus delivered into the root zone stimulates root-system development, while adding sulphur in rapeseed cultivation improves nitrogen uptake. Sub-soil application in the seed strip makes it possible to use highly concentrated doses without the risk of scorching young seedlings. Thanks to two-level granule delivery, plants benefit from fertiliser throughout the entire growing season.
