Farming changes help reduce the average heat in Europe

European farmers often have the habit of plowing the land after harvest to kill the grass and make the soil loose every time it starts planting new crops.

However, a group of Swiss and French scientists recently suggested that changing this traditional farming method could help the average temperature of the old continent drop by 2 degrees Celsius.

In the study published in the journal of the American National Academy of Sciences published on June 23, scientists said that unpaved plots have a lighter color, slow moisture release and absorption of light. less sunshine than plowed plots.

Therefore, the thermal background in areas of agricultural land without plowing is usually lower than in other places. The study shows that this phenomenon can be clearly noticed during hot weather.

The conclusion of the scientist has received mixed reactions of public opinion. Supporters say changing this farming habit also brings many other benefits such as saving water, preventing the risk of soil erosion and even preventing global warming.

However, many people disagree that changing cultivation habits in the direction of no-till will increase the use of chemicals such as herbicides .

Currently the US and many countries in South America have adopted this farming technique and can achieve productivity three times higher than traditional methods.

The proportion of agricultural land here accounts for more than 85% of un-plowed agricultural land in the world, while in Europe this rate is only 2%.

In a report published four years ago, the US Department of Agriculture said no-till farming techniques could help reduce a large amount of greenhouse gas emissions , believed to be the main culprit in the situation. The Earth is warming.
