The purpose of draining
The purpose of drainage is primarily to lower the groundwater levels. Which will result in the increasing possibilities for use of the drained plot. The groundwater rises to ground levels less often, which reduces the risk of trampling a tracking. Due to drainage, a plot can be used earlier in the spring and longer in the autumn. The grazing period is therefore longer. There is also less crop loss and less chance of damage to the turf and the soil. On grassland, the best quality grasses can best survive in dry conditions. Trenches and often ditches can become obsolete due to the use of drainage. So, you will gain land and cultivation will become more efficient. Plots that were previously exclusively used as grassland can now also be used for the cultivation of maize and arable crops due to drainage. This must be taken into account when constructing drainage because different drainage standards apply to arable farming. Lowering the groundwater levels through drainage applies to the highest groundwater level. This occurs mainly in the period with a precipitation surplus; the winter period and the transition to spring and autumn. The lowest groundwater level occurs during the period with a precipitation deficit; the growing season.
