The environmentalist Mustafa Sheikhmos said that burning of the crops killed worms and nitrogenous bacterial organisms.
According to the environmentalists, these materials help stabilize atmospheric nitrogen in the soil, which is essential for soil fertility, analysis of previous crop residues, transformation into beneficial nutrients and formation of iron, copper and phosphorus materials.
As the harvest of wheat and barley approached, the fires consumed tens of thousands of hectares of wheat-cultivated fields, starting from the Dirk area to the east and to al-Tabqa area in the east in northern and eastern Syria and Daesh claimed responsibility of these attacks.
"These fires have increased the amount of harmful gases emitted from burned fields, including CO2 and CO1," he said.
"The fires also lead to high temperatures and all this leads to the destruction of the ozone layer that protects the atmosphere."
Besides fires, most farmers burn their fields after the harvest.
"Farmers have to protect their crops and not burn them so they can plant them again," he said.
