What is the advantage of guelle

Why is liquid manure applied to arable land and grassland at all?

Liquid manure has two unbeatable advantages: it usually contains all the important nutrients for the plants and at the same time provides organic matter for the soil, which ensures sustainable soil fertility.

Plants need nutrients in order to grow and produce what we want to harvest: for example the potato tuber or the cereal grain. But it's not just about the quantity: the farmer not only wants as many potatoes or as much grain as possible, the quality is also important, especially for the end consumer. So the ingredients also play an important role. For the baker, wheat must have very specific ingredients that are not quite as important in feed grain. The starch content is important in table potatoes - the higher it is, the more floury the potato will be. In addition to other factors such as the choice of variety and the water supply, this also depends on the nutrients available.

The second, very important part of the liquid manure is the organic matter that it brings with it to fields and grassland and thus builds up the humus content. If the soil is enriched with humus, it can hold nutrients and water better and release them back to the plants. In addition, the humus helps to build up a buffer against pollutant inputs in the groundwater. He creates this by the substances contained in the humus, the humic substances, sticking to the existing soil particles. More nutrients, which are also available to the plants, can accumulate on the resulting soil particles. On the other hand, pollutants can also accumulate, which are then not washed out into the groundwater, but are gradually broken down by the microorganisms in the soil.
