Roughage tour Corn - week 42

Mixed feelings about dry matter figures for silage maize

21 October 2022 - Manon van der Meer

All silage maize has now been chopped on the plots of the dairy farmers who participate in the Boerenbusiness Roughage tour. The maize season is thus over and the participants in the roughage tour each have their own view of this year's cultivation. The elaboration of the new Common Agricultural Policy (CAP) and the adjusted derogation are on the agenda for the coming 2023 growing season. When asked, no dairy farmer is waiting for that. 

At Frank Rooker from Aartswoud (North Holland) it has been a good growing season for the maize. The many hours of sunshine, coupled with some precipitation, have resulted in a good yield. Every now and then he got a shower on the plot, where colleagues elsewhere in the Netherlands got little or even nothing on their crop. Rooker drove over his corn potato pulp in the pit and just had a sample taken. 

Low yield purchases
Jan Henk Waterink from Beerzerveld (Overijssel) had less luck with his maize this year due to the prolonged drought. He silaged the maize twice. The first time on September 9 and the second time on September 20, where the first pit was very dry with a dry matter percentage of 40%. Fortunately the second pit was slightly wetter. Waterink had to buy part of it because he harvested too little volume. If it's up to him, he'd rather grow a few more hectares of maize. This of course depends on the impact of the plans regarding the derogation and the new CAP. Waterink prefers to grow 40% maize and 60% grassland, instead of the 80% grassland and 20% maize land he has this year. 

In Sint-Oedenrode (North Brabant) there was Joost van Nostrum the maize yield this year is also lower than normal. Despite the extreme drought, it did not disappoint. It will be a while before he starts feeding the corn. Only then does it appear whether the cows want to eat it. Van Nostrum has irrigated a lot this year and will not adjust this strategy in the coming year, despite the lower yield.

The table shows how the dry matter percentage has developed in the last weeks of the maize season. It is a fact that it went hard with the ripening. That surprised a number of maize growers.
