Steaming is one of the best ways to sterilize potting soil. It must be done for 30 minutes (until the temperature arrives 180F). The process has to be performed with or without a pressure cooker. If someone wants to use a pressure cooker, he should clean it and keep several pure cups of water in the cooker (not more than 4 inches in depth) and then need to keep it for 15 to 30 minutes. This technique will help you sterilize soil easily.

Positive Sides of this method

At present, our cultivating land is subsiding day by day because of increasing the population’s growth. As the population grows, ensuring their food has become the world’s most significant challenge for the farmers. As far as we are concerned, we have to solve this problem scientifically. Since the beginning of the world, people have been ensuring their food requirements through agricultural work.

But environmental pollution, as well as climate-changing, is a significant cause of food shortages. The major problem of food shortages is not only population growth but also land shortage. It is possible to grow good crops in our land by disinfecting microorganisms. Most people don’t know how to use the sterilization process. But sterilizing the soil is not as a different task as the typical cultivator believes. Above all, it has become much more comfortable. Several popular methods of sterilizing process are handy to implement (by following the given instructions).

  • Crop production using disinfection in the cropland increases more than before. Farmers can produce more crops on scarce land.
  • Notably, Vietnamese and Chinese farmers are getting the benefits of using these methods. They are providing their food all over the world.
  • We also disinfect the soil in our garden to cultivate a variety of vegetables, which helps meet our family’s nutritional needs. Those who have a flower gardening hobby may use this method to enrich the flowering plants’ nutrition.

How the world is getting benefits

Climate change, rising temperature, and environmental pollution are making the earth inhabitable for animals and birds. One study found that global temperature is rising as vegetation declines, and its impact is creating harmful effects on people. We need to control the condition, and we should plant a lot of trees on both sides of the yard and the road. The land should become suitable for the survival of the plant.

We can decontaminate the land easily by using a disinfectant. This technique will allow many plants to grow, and it will produce a variety of vegetables in the greenhouse. Also, more plants will increase the amount of oxygen in the earth, so the earth’s temperature will decrease, and we will able to live in peace. Sterilization will enrich the soil’s water-holding capacity, which will increase the fertility of the land. On fertile land, we will produce more crops, which will help us a lot in any epidemic situation.
