The 2025 season in the Poltava region proved to be a good test for various tillage systems.

Seeding took place relatively late, on 3 June 2025. During the growing season, 281 mm of precipitation fell, of which 203 mm fell after seeding. At first glance, it might have seemed that there was sufficient moisture. However, after emergence, the maize suffered cold stress \u2014 minimum temperatures dropped to +4 to +6 \u00b0C.

In the strip-till variant, the field was left as stubble following the previous crop, which was mustard.

Autumn excavations revealed a typical pattern. The root system had formed a distinct zone concentrated at a depth of 10 to 25 cm: precisely in the area of fertiliser placement. The main mass of roots penetrated to 50 to 60 cm, though individual roots extended as far as 80 to 90 cm.

The STRIP-MASTER EN 6000 strip-tiller ensures strip tillage with a row spacing of 45 to 80 cm.

Autumn excavations revealed a different root system architecture: the roots were evenly distributed in the 5 to 20 cm layer, with individual roots reaching depths of 20 to 25 cm.

An autumn crop inspection revealed that the root system was concentrated at a depth of 40 to 50 cm, with individual roots penetrating to a depth of up to 90 cm. No horizontal consolidation was observed. In this case, the depth of tillage was the decisive factor.<\/p>\n

According to findings from the demonstration plot, in the 2025 season, strip-till with localised fertiliser placement demonstrated the best balance between root penetration depth, absence of consolidation and stability of plant development. The creation of strips in spring promoted rapid infiltration of heavy rainfall and the development of a deep root system. The strip-till technology with fertiliser placement into the soil profile yielded the best agronomic result \u2013 a yield of 9.9 t\/ha \u2013 as well as the best economic result \u2013 a profit of USD 719\/ha.<\/p>\n

In terms of root system development, disc harrowing showed the lowest positive effect. However, in the end, both disc harrowing and loosening achieved the same yield of 8.8 t\/ha and approximately the same economic result. Ploughing, on the other hand, showed the lowest yield and profitability.<\/p>\n

The demonstration plot in Poltava-Sad clearly showed that tillage is not merely a question of the chosen depth or number of passes. It is a strategy for managing moisture, root system development and crop stress resistance. The main conclusion from this trial is clear: there is no versatile solution. There is only technology that better suits specific soil and climatic conditions. And it is precisely such field trials, carried out by BEDNAR and Agrilab, that help make informed decisions.<\/p>\n"},{"acf_fc_layout":"section-news-cols","item-cols":[{"item-title":"","item-title-h":"h3","item-photo":"https:\/\/www.bednar.com\/wp-content\/uploads\/aktuality\/2026\/ua\/bednar_presentation_agrilab-2026-51-scaled.jpg","item-content":"","item-photo-align":false,"item-content-color":false}]},{"acf_fc_layout":"section-news-title","item-title":"","item-content":"
