Climate change and soil protection

Due to the higher evaporation rate, soils are becoming drier. With each degree, 7% more water evaporates. The annual average has risen by around 1° in 30 years.

Warmer atmospheres convert water vapour more quickly into clouds and in turn into precipitation. It thus rains more heavily than before. This means that, even if the amount of rain remains the same, it will rain less often.

Precipitation must be stored in the ground as best as possible. Heavy precipitation must be able to easily infiltrate into the soil by creating a pore system that functions as well as possible and by increasing biological activity (earthworms, soil fungi etc.).

In addition, extreme soil heating, which destroys all biological soil activity, must be prevented.

  • Humus preservation and formation
  • Emissions reduction accompanied by lower production costs (e.g. higher nitrogen use efficiency)
  • Take advantage of rain - the ground should always be covered with plants
  • More frequent heavy rain events should not run off the surface and possibly cause erosion
  • Do not till deeply, especially in the spring when the soil is already dry
  • Minimum soil cover in the winter and targeted cultivation of catch crops to prevent the discharge and leaching of nutrients.
  • Obligation to rotate crops. In addition to a reduction in tillage intensity, the soil cover through crop residues and catch crops will also have to increase.
  • Cultivation of at least 5 main crop species, including legumes, ..., the avoidance of chemical-synthetic plant protection
  • The states must use 35% of agricultural funding for environmental and climate-related services - example NRW: Reduction of fertilisers and pesticides, soil and water protection. Improving the living conditions of wild animals and plants. Supporting organic farming.
  • The minimum ground cover (GAEC 6): On at least 80% of arable land, there is a minimum ground cover requirement between 15th November and 15th January. To fulfil this, you can e.g. leave the stubble of the previous crop standing without any cultivation or carry out mulching, non-turning tillage after the harvest. It is also possible to grow perennial crops, winter crops, catch crops or a mulch layer.
  • Humus preservation and formation
  • Organic farming and organic agricultural methods are promoted and given priority
  • Emissions reduction accompanied by lower production costs (e.g. higher nitrogen use efficiency)
  • Reduction of pesticides
  • Cultivation of catch crops and undersowing
  • Significant reduction in tillage intensity while at the same time significantly higher effectiveness and efficiency of tillage measures
  • Food security despite climate change and biodiversity loss
  • Reduction of nutrient losses by at least 50% without a deterioration of soil fertility. Reduction in the use of fertilisers by 20% by 2030
  • Nitrogen fertilisation 20% below the calculated fertiliser requirement on average across areas
  • Higher nitrogen use efficiency is necessary to maintain yield and quality:
    • A significant reduction in nitrogen losses must be aimed for
    • Cultivation of catch crops based on the crops with high amounts of residual nitrogen in the soil (winter rapeseed, grains and fodder legumes, potatoes, vegetables, sometimes silage maize) in combination with significantly reduced tillage intensity
  • Field-related N upper limit for organic fertiliser: maximum 170 kg N from organic fertiliser
  • Field-related upper limit of 170 kg of organic nitrogen
  • Autumn fertilisation only in exceptional cases
  • Mandatory catch crop cultivation. N fertilisation is now only permitted for crops sown after 1st February if a catch crop is grown on the affected area and not ploughed before 15th January.
