Farmers all over the world, having a large arsenal of fertilizers, spend them thoughtlessly, causing great harm to the environment. New smart fertilizers will reduce greenhouse gas emissions, which is similar to removing more than 1 million cars from the face of the earth.

Fertilizers make it possible for farmers to receive generous crops and feed the growing world population, but this causes irreparable harm to the environment. One of the problems is the too much use of top dressing - often they are abundantly sprayed or scattered over vast areas.

In the past few decades, scientists have invented fertilizers that have controlled release. Instead of the usual granules, such fertilizers are placed in capsules that control their entry into the soil. Plants gradually absorb them, instead of doing it in one step.

Capsules with fertilizers can be configured so that they release substances in batches, using a certain interval, which depends on several factors - humidity, temperature and acidity. When using land mapping, this significantly reduces the use of fertilizers, which is important for farmers and ecosystems.

According to scientists from the University of Michigan, the use of smart fertilizers and soil mapping will reduce greenhouse gas emissions by 6.8 million tons per year, which is equivalent to removing 1.5 million cars from roads.
