## Table description

This table provides information per crop about the cultivated and harvested area, yield per hectare and the total yield in a crop year. The data are available for the Netherlands as a whole and by province.

Applying crop rotation helps a farmer to avoid deterioration in soil fertility.

A cultivation plan is prepared annually, to make sure that the same crop is not cultivated in the same place year after year.

Usually, one third of the arable land is covered with cereals (mainly winter wheat and spring barley), a quarter is covered with potatoes, one eighth is covered with sugar beet, and one tenth is used for vegetables(mainly onions) as well as a green fodder crop (mainly green maize).

To obtain the figure for the yield, first a preliminary harvest estimate is made. This takes place from August to October.

The estimate is made definite from December to March.

The yields per hectare are rounded off to the nearest 100 kilograms. The total yields are rounded off to the nearest 1000 kilograms.

Data available from: 1994.

Status of the figures:

The figures of 2021 are provisional. The figures up to 2020 are definite.

Changes as of 29 October 2021:

The provisional figures of the harvested areas of 2021 for fibre flax and linseed have been added to the table. The provisional figures of the gross yield per hectare and of the total gross yield of 2021 for grain maize, corn cob mix, green maize, fibre flax, linseed, hemp, chicory, kidney beans, the potatoes total, ware potatoes, sugar beet, seed onions and onion sets have been added to the table.

When will new figures be published?

The preliminary harvest estimate figures for cereals are published at the end of September and for all crops in late October of the harvest year. The final harvest estimate figures are published in January and are updated in March of the following year. These figures can be changed until the end of September.

## Description topics

- Area under cultivation
- Area of cultivated land in use for growing crops.
- Harvested area
- At the preliminary harvest estimates this area is in principle equal to

the area under cultivation. However based on information from experts on

expected crop failure it is possible to make an estimate of the area that

probably will not be harvested. When this is the case the harvested area

is smaller than the cultivated area.

Definite figures are based on already harvested areas and areas expected

to be harvested later on. This is the area on which production

has taken place effectively. Due to circumstances (for example flooding)

this (surface) area can be smaller than the original (surface) area used

for cultivation. - Gross yield per ha
- In determining the yield per hectare (the average yield figure) only the

hectares which are effectively harvested or will be harvested are

counted. Hectares of which the harvest is lost (for example due to

flooding) are not counted.

The yields of grain corn and corn cob mix have been calculated in the

situation in which these harvested crops contain a humidity of 35 percent.

Green maize is calculated at a moisture content of 65 percent.

In the preliminary estimate the yield of cereals (wheat, barley, oats, rye

and triticale) are defined as the gross weight of the harvested grains.

The definite estimate is the weight in the situation where each grain

would contain 16 percent moisture.

Explanation:

Cereal with 16 percent moisture (or less) is so dry that it can be

stored without problems. More moisture would mean that the grain first has

to be dried, before it can be stored. Drying the crop costs money, the

companies therefore prefer harvesting by 16 percent moisture content.

But this does not always work; in reality, the grain contains more water.

However, in order to get a good estimate of the actual 'dry' yield

all individual statements of the yields per hectare (from which the actual

moisture content is known) are recalculated to the situation with 16

percent moisture. - Gross yield, total
- The total yield (total gross production) includes the whole area which

has been harvested or still will be harvested. The total yield also

includes the part of production that for some reason is unsuitable for

its original purpose. This only applies if the crop can still be used for

other purposes (for example, potatoes which can only be used for animal

feed). This is the reason why the gross yield does not equal the

commercial production.

The yields of grain corn and corn cob mix have been calculated as the

harvested crops contain 35 percent moisture. Green maize is calculated at

a moisture content of 65 percent.

In the preliminary estimate, the yield of cereals (wheat, barley, oats,

rye and triticale) is defined as the gross weight of the harvested grains.

The definite estimate is the weight in the situation where each grain

contains 16 percent moisture.

Cereal with 16 percent moisture (or less) is so dry that it can be

stored without problems. More moisture would mean that the grain first has
