Chemicals enter the environment every day, but there is hardly a substance group that is used with more purpose and in such large amounts than plant protection products.
The world’s soils are neither barren nor dead, for they constitute the habitats of one trillion times more bacteria than there are stars in the universe. Even a mere teaspoon of soil contains a million bacteria, 120,000 fungi and 25,000 algae. These microscopic organisms perform key material-cycle functions.
Agricultural landscapes are habitats for many wild animal and plant species. Fields, meadows, pastures and hedges serve as a food source and provide breeding and refuge areas. However, intensive agriculture significantly limits this potential. Biodiversity in agricultural landscapes has been declining for years.
Nitrogen is an essential nutrient for all living organisms. The use of mineral and organic nitrogen fertilizers to increase yields is therefore common practice in agriculture. Careful and needs-based application is crucial. Excess nitrogen can pollute water and land ecosystems and adversely affect the climate, air quality, and biodiversity.
Pesticides are used extensively in agriculture. Their main purpose is to keep crops healthy and weeds and pests at bay. However, they also have undesirable effects on biodiversity and water quality in adjacent biotopes.
Germany’s farming sector uses the largest amount of land, but is at the same a lynchpin of our economy – one that provides a reliable food supply and produces sustainable raw materials. The farming sector also plays a key role when it comes to preservation and development of the man-made environment. But increasingly intensive farming brings with it a host of eco-unfriendly effects.
