Plots Crop tour show difference of 44 tons

From the first trial harvests on the plots participating in the Boerenbusiness Crop tour shows that the yields are very variable. The difference between the parcel with the highest and lowest yield is no less than 44 tons.

The plots participating in the Boerenbusiness Crop tour, still in fairly good condition (relatively speaking). This therefore concerns plots that are heavily irrigated (such as the plots in Hank and Spijk). On the plot in Hank there is currently about 52 tons per hectare under the plants, while in Spijk there is 44,7 tons per hectare. Both plots were irrigated 5 times.

Southwest
Yields are on average lowest in the southwest of the country. in Zeeland (Scharendijke) could not be irrigated. This is also reflected in the trial harvesting, because only 23 tons per hectare were harvested here. In Fijnaart, 34,3 tons per hectare was removed from under the plants (irrigation took place 3 times).

Also on the plot in the John Kerkhoven Polder the effects of the drought are clearly visible. This parcel was irrigated for the first time this week. There is about 30,3 tons per hectare under the plants.

Southeast
On the plot in Bocholtz the potatoes look pretty good. Irrigation has taken place here 3 times and there is about 43,3 tons per hectare under the plants. The plot in Escharen (sandy soil) was irrigated 6 times. For the time being, this results in a yield of 48,3 tons per hectare.

On the plot in Marknesse is by far the largest yield measured. On that plot, 67 tons were covered by plants. The potatoes were planted early and showed an advantage over the other plots throughout the season. This plot has been irrigated 4 times.

On the plot in Middenmeer, the yield per hectare was 54,5 tons. On this plot, the non-inversion tillage is now showing better yields. The plot was irrigated 3 times 15 millimeters. On the plot in Biddinghuizen a yield of 44,7 tons per hectare has been harvested.

Average Yield
Up to and including week 31, the average yield over the plots is 44,2 tons per hectare. If we compare this with test harvesting from various trading houses and chip processors (based on the 5-year average), then this test harvesting is 10% lower.

It should be noted, however, that almost all plots that participate in the Crop Tour are on clay soil. This clearly creates a different picture than what can be seen nationally on lighter soils. The hectare yields are currently clearly lower there.

Rained or not
The fact whether or not it was possible to irrigate also has an impact. This is clearly reflected in Scharendijke. Of the 10 plots, 9 can be irrigated. Nationally, the percentage of plots that are irrigated is around 50%. As a result, the national picture (with regard to the hectare yield) will deviate significantly from these trial harvestings.
