World Soil Day 2019: Let's Pledge to Stop Soil Erosion and Save Our Future

soil

Soil is important as it provides the medium for the growth of plants, habitat for several insects and organisms. It is made up of minerals, organic matter and air in different proportions. Soil is also the source of four important 'living' factors i.e. food, clothes, shelter and medicine. Thus, conservation of soil is essential. To raise awareness about soil and its importance, World Soil Day is celebrated every year on 5th of December.

Theme of World Soil Day 2019

The theme of World Soil Day 2019 is - Stop Soil Erosion, Save our Future. The theme focuses on how we can prevent soil erosion and save our future. On World Soil Day every year, different programmes and events are held to tell people about the importance of soil in their lives.

Why 5 December has been chosen as World Soil Day?

The date 5th of December was selected because it corresponds with the official birthday of the King of Thailand, late H.M. King Bhumibol Adulyadej, who was one of the main proponents of this initiative.

Understanding the Importance of Soil Conservation

Soil conversation is basically the method to conserve or preserve soil. There are numerous reasons for the loss in soil fertility like over-use, erosion, salinisation & chemical contamination. Soil erosion takes place when the top soil gets removed. This top soil is essential for nutrients, micro-organisms, which are necessary for plant growth and shine. There are several ways to conserve soil and below we have mentioned a few of them.

How to Conserve Soil?

Here are few ways in which we can preserve soil:

Green Manures

Green manures are grown to fertilise the farmland on which it grows. This method can improve the structure of the soil and restrain the growth of weeds.

Crop Rotation

In order to make soil valuable in nutrients crop rotation method is followed. Like radishes and turnips are rotated with various cash crops to maintain the nutrient value of the soil.

Terrace farming

It is a process of carving multiple, flat levelled areas into hills. This is done to prevent run off & hold the soil nutrients in the beds.

Contour Ploughing

In place of planting the crop, contour ploughing is done to obtain the desired farmland. This is done for farmland on slopes to avoid run off and improve crop yields. To reduce the soil erosion, ploughing is done along the contours of the land.

Salinity Management

When water evaporates from the soil, salt is left that can further damage the soil and nutrients can be lost. Humic acids are used to avoid this. In addition, saltbush is also grown to revive the soils and replace the loss of the nutrients.

Let's together pledge to conserve soil, stop soil erosion and save our future...
