Optimum germination conditions

There are three factors that are key deciders on the emergence of our plants: temperature, moisture and oxygen. These parameters are determined primarily by the type of soil, the location and the weather.

In terms of farming, these three parameters are difficult to influence. One of the biggest influencing factors is the pore volume of the soil. A loose, crumbly tilth structure with many medium-sized pores can absorb water better and provide the roots of each plant with sufficient space and oxygen. It can also warm up evenly and quickly, creating optimum germination conditions.

Soil aggregates

Soil aggregates or soil particles are created by the formation of clay and humus complexes and biological activity below ground. Aggregates can be several millimetres in size and form a very stable structure that promotes the exchange of water and gas.

Harmful compaction

If forces act on the ground in excess of the load-bearing capacity of the soil, the aggregates are pushed together to counteract the pressure. This reduces the pore volume. Fine pores of less than 2 µm are particularly problematic here, because they absorb water without making it available to plants.

This is frequently caused by incorrect arable management. A high number of passes with heavy equipment in wet soil conditions have the worst impact. Ultimately, every type of cultivation leaves its mark and in some cases compaction in the form of consolidation is even favourable.
