9. Modern agriculture and its impact on environment

Background

With the advent of technological advancements in agriculture such as better irrigation systems, use of high yielding seeds, fertilisers, pesticides, multiple cropping system, etc. farmers are getting better yields and profits. However, most of these practices, if not properly monitored or judiciously practised, can have an adverse effect on the quality and fertility of soil, water table, quality of water in river and lakes and others.

Methodology

The project should be carried out in groups.

1. Select an area where modern agri-practices are being followed.

2. Select another area where traditional practices of agricultural farming are followed. Project Book in Environmental Education

3. Find out the yield per unit area in each case for the same crop.

4. Collect samples of water from ponds, wells, lake or tanks, if any, from the area surrounding the agriculture  fields. Test the water samples with the help of pH papers.

5. Find out the alkalinity or acidity of the soil with the help of pH paper.

6. If a microscope is available, examine a drop of each sample for presence of living organisms.

7. The above information can be further substantiated from the village elders, agriculture scientists, and Block Development Officers of the area.

8. Obtain more information about soil and water.
