Do GM crops have an effect on soil?

 

Globally, between 20,000 -50,000 km2 of arable land is estimated to be lost annually through degradation, especially soil erosion. GM crops can protect soils from erosion through less ploughing, conserving soil moisture, too. GM herbicide tolerant crops reduce the need to plough fields in preparation for planting crops. This saves fuel because less tilling is necessary. GM insect resistant crops require less treatments with insecticides, which also decreases the need for tractor use.
