Fertile Soils for High-performance Crops, through Balanced Fertilisation
The soil actually represents the top layer of the earth’s crust, which serves as a habitat for animals and for plants. Plants use their roots as a mechanic anchor, on the one hand, but also as a system for taking in water and nutrients previously stored by the soil. In agriculture, the storage capabilities of the soil are the decisive factor for consistently harvesting premium crops, even under continuously changing weather conditions. In order to properly manage the soil, it is therefore necessary to maintain these vital functions. Detrimental soil compaction, erosion, salinisation etc need to be avoided, as is the “depletion” of nutrients.
In order to thrive, plants require the nutrients nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), sulphur (S), sodium (Na) and trace minerals. They draw these nutrients from the soil, and in a natural ecosystem return them completely after dying-off. The natural nutrient cycle is therefore a closed one.
In agricultural ecosystems, independent of eco or conventional agriculture, nutrients are permanently removed from the soil by the crop or products (grains, potatoes, vegatables, dairy products, meat, etc). The products generated are sold by the farm and are consumed by people everyday. There is no return transfer of nutrients to the soil. Instead, these nutrients are irretrievably lost to the sewage system. For sustaining long-term fertility, the nutrients removed by the plants need to be returned to the soil. Taking into consideration our modern way of life and society’s needs, this is not possible without mineral fertilisation; otherwise soils are depleted and would soon lose their fertility.
Oily!, Drought resistant!, Sweet! – with Potassium and Magnesium Fertilisers of K+S KALI GmbH
The current ad campaign of K+S KALI GmbH presents the advantages of Potassium and Magnesium Fertilisers in a playful way by comparing these product strengths with every-day items. With this campaign, K+S KALI GmbH draws attention to the importance of a balanced nutrient supply to plants.
