Polish growers see excessive OSR yields after transfer to biologicals

Polish grower Julian Grygolec is harvesting bumper oilseed rape yields of 5t/ha throughout his farm with a deal with utilizing organic merchandise and foliar feeds to maintain his crops nicely equipped with important vitamins.

The 5t/ha determine is his common yield throughout 150ha of rapeseed in the summertime of 2022 on his fertile soils in northern Poland, utilizing a comparatively low stage of nitrogen fertiliser at 180kg/ha.

“We normally get good yields on this farm, so 5t/ha is regular, 4t/ha could be a catastrophe,” he jokes to Farmers Weekly.

The heavy soils on his 530ha farm in Pomerania, 25 miles south of the Baltic port of Gdansk, have a tendency to present good yields even in dry springs and summers – which have gotten extra commonplace.

His winter wheat averaged 9.2t/ha in 2022, in a variety from 8t/ha to 11t/ha, and his sugar beet averaged 80t/ha.

Organic use 

He has been utilizing the organic soil improver RevitalPro for the previous six years, utilized within the autumn and labored into the soil, and he’s satisfied it’s serving to to enhance the soil construction on the heaviest of his land.

He has seen elevated earthworm numbers and the soils are simpler to work.

As well as, he’s utilizing the nitrogen-enhancing organic AzotoPower, which has helped him minimize his nitrogen wants by 60kg/ha on his rapeseed and nonetheless keep good yields.

That is utilized at drilling time, after which within the spring, and doesn’t want incorporating into the soil.

Mr Grygolec is being suggested by Rafal Glodnicki from agronomy group ProCam.

The group has 120 agronomists working throughout Poland and is the unique distributor for these organic merchandise, manufactured by the Polish group Bio-Liden.

ProCam has expanded quickly in Poland prior to now 18 years, led by managing director Michal Ciszak and head of agriculture Dariusz Wyczling.

As well as, a programme of foliar feeds utilized 4 to 5 instances all through the spring season has additionally assist his crops in the direction of excessive yields.

These could be utilized with different merchandise, resembling fungicides and pesticides, to minimise the variety of passes throughout the land.

Fertiliser value hikes

Mr Grygolec has turned to biologicals and foliar crop vitamin to deal with the sharp rise in nitrogen fertiliser costs and the usually restricted availability of nitrogen attributable to the sharp hike in power costs following the Ukrainian-Russian battle.

The struggle simply throughout the Polish-Ukrainian border has raised grain and rapeseed costs internationally, however home costs can fluctuate.

When Ukrainian grain is diverted by rail and street by means of Poland due to the restricted commerce by means of Ukraine’s Black Sea ports it’s offered on the Ukrainian market and depresses native costs

He’s additionally targeted on minimal disturbance when cultivating his soils to retain moisture in dry climate, together with his farm solely seeing an annual rainfall of 600mm, with much less snow within the winter, because the final “arduous” winter was in 2016.

He additionally has to deal with the impact of climate change together with his oilseed rape flowering in April as night-time temperatures fall to -4C.

Local weather change is having an affect and making the dangers greater for a grower. We don’t know what to anticipate from the climate and we’re having much less snow, which implies much less water for the crops,” he says.

He has decreased ploughing on the farm to as soon as each three to 4 years and this has introduced an enchancment in soil well being in addition to a transfer in the direction of strip tillage for sugar beet.

Mr Grygolec farms 530ha of arable land, with 300ha of wheat, 150ha of oilseed rape and a sugar beet space of 50ha on a former state-run farm of which he was a director.

He was in a position to purchase a part of the farm when the land was privatised following the autumn of communism.

He sows a mix of as much as 4 totally different oilseed rape varieties within the combine, together with Absolut and Batis, as he finds this offers him good yields and limits illness stress.

He makes use of the organic DeliaStop from Bio-Liden to discourage cabbage root fly infestations within the autumn and into winter.

His foliar feed programme incorporates ProLeaf Max, which offers micronutrients resembling manganese, copper and a few nitrogen, and in addition some Delta merchandise, which give micro and macro vitamins.

These are the identical merchandise Tim Lamyman on the Lincolnshire Wolds makes use of to supply his top-yielding crops,

For his major nitrogen functions, Mr Grygolec makes use of liquid early within the season, as it’s extra simply absorbed by vegetation, achieves a greater unfold and works higher in dry circumstances.

He then switches to strong nitrogen later within the season to keep away from any scorching of the crop from concentrated liquid merchandise.

His general stage of nitrogen fertiliser used on the oilseed rape has come right down to 170-180kg/ha from the 240kg/ha he was utilizing beforehand, with out having a detrimental affect on crop yields.

He says he’s on the excessive finish of enter spending for oilseed rape crops in Poland, however the result’s worthwhile for his high-yielding crops.

He does admit the crop is harder and nerve-racking to develop than winter wheat, however says the rewards are larger as a result of excessive yields.

Champions League winner 

Norbert Lipowski gained the “Champions League” of prime winter wheat yields in Poland, with a crop of 12.358t/ha.

This was because of him rising his 2022 harvested crop after a nitrogen-fixing bean crop, helped by beneficial climate and utilizing biologicals aimed toward fixing extra nitrogen.

His prime yield got here on his 180ha household farm in north-east Poland, within the Masurian Lakes space in the direction of the Russian and Lithuanian border, the place he farms together with his brother and two sons.

He grows 100-110ha of winter wheat and final 12 months’s crop of the range Argument was the very best yield he has ever formally recorded.

He used the organic spray AzotoPower throughout all his winter wheat within the spring.

This allowed him to chop his use of bagged nitrogen by 30kg/ha right down to 180kg/ha, whereas his turkey unit offers manure for the land as soon as each 4 to 5 years.

The yield competitors covers a variety of crops from wheat to grain maize, is organised and run by agronomy group ProCam, and covers the entire of Poland.
