The Waterwijzer Overlay offers the following result types:

Result type Unit Description
DAMAGE_DRY % yield loss The loss of agricultural yield for drought scenarios, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These yields are calculated by the Waterwijzer Landbouw api. When the water levels in the ground are too low, roots are unable to absorb enough moisture.
DAMAGE_WET % yield loss The loss of agricultural yield due to high ground water levels, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These yields are calculated by the Waterwijzer Landbouw api. When the water levels in the ground are too high, subsurface air is replaced by water and plant roots cannot obtain enough oxygen.
DAMAGE_INDIRECT % yield loss The loss of agricultural yield due to indirect causes, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These yields are calculated by the Waterwijzer Landbouw api. Indirect causes relate to the type of soil, type of crop and water levels.

Taken into account are:

  • soil temperatures in comparison with crop growth calendar;
  • plowing difficulty for a soil and season;
  • sowing problems for the given water levels, crop and soil;
  • germination problems due to sub-optimal water concentrations in the soil;
  • harvest issues due to not fully grown crops;
  • sub-optimal conditions for grassland growth;
DAMAGE_SALT % yield loss The loss of agricultural yield due to salt water irrigation or salt water seepage, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These yields are calculated by the Waterwijzer Landbouw api. Too much salt concentration leads to a reduction of water absorption of plant roots, increased toxicity, problems with nutrients absorption and decreased root growth.
DAMAGE_TOTAL % yield loss The total loss of agricultural yield for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These yields are calculated by the Waterwijzer Landbouw api.
