As we celebrate World Soil Day on Sunday, 5th December 2021, we are reminded of the vital role that soil has to play in our survival on planet earth.<\/p>
World Soil Day 2021 highlights the issue of soil salinization around the world. Salts are naturally present in soils, but factors \u2013 primarily poorly designed irrigation schemes \u2013 can increase the amount of salt in soils. This process is called salinization, and it breaks down soils and reduces the ability of soil to grow food. <\/p>
Soil salinization is a major threat to our ecosystems, and a global threat to agricultural production, food security and sustainability \u2013 particularly in tropical and arid\/semi arid areas. Already, huge parts of India, Pakistan, Afghanistan and the USA are no longer suitable for agriculture. <\/p>
