Why is burning not a recommended practice to manage crop residue?
Burning may seem like a simple method of managing crop residue, but it is actually expensive and damaging. Burning causes problems in many ways. Economic loss Straw has a value. Straw is a source of soil nutrients and organic material. Decomposition releases these resources to build and maintain the soil. Soil resources, in turn, enhance crop production. Most of the organic material and nutritional content of straw is lost upon burning. Straw also provides soil cover. Soil cover reduces evaporation, increases water infiltration, increases snow trap, reduces wind and water erosion and provides a good microclimate for developing seedlings. Liability Individuals who burn are liable for damages from the fire and smoke. Fire can easily get out of control. Smoke can be dangerous if it drifts across roads and impairs visibility. Health While smoke may only be a nuisance to some people, it can be a serious health risk for those with respiratory problems, such as asthma or emphysema. Statistics
