Back To The Earth NCERT Book Class 8
CROP PRODUCTION AND MANAGEMENT
It was a bright Sunday morning. Working in the garden was the favourite pastime for the Malhotra family. It was great fun for little Snigdha to help her father clean up the leaves that were shed by the trees. Her father would then dump them into a pit and cover it.
“Now these leaves would rot and form compost after some time. We could use this compost in place of expensive fertilizers in our garden”, explained Snigdha's father. What causes the rotting of so many leaves? How do these dead leaves get changed into such useful compost? What happens to the millions of leaves that get shed from trees in forests? The list of questions that were bothering Snigdha seemed to be endless. Let us findout through this simple activity what exactly happens when leaves fall on the soil?
You will need:
a) Leaves of the same tree e) Brick Powder
b) Graph Paper / Square grid f) Magnifying glass
c) Garden soil g) Distilled water
d) 2 Pots h) Khurpi
Take two leaves and attach a piece of paper to each of their petioles. Label them A and B. Draw their outlines on a graph paper. Count the total no of squares covered by the leaves to find their area.
Take two pots 1 and 2. Partly fill pot 1 with garden soil, place the leaf A flat on the surface and pour some more soil till the pot is full. Take some redbrick powder. Now partly fill pot 2 with brick powder. Place leaf B flat on this surface and pour the remaining brick powder on top of the leaf till the pot is full. Keep the contents of both the pots A and B moist by adding water boiled & cooled to room temperature.
Dig up the soil in both the pots every two weeks to see if there are any changes in the leaves. Bury the leaves again. After two more weeks, dig up to take out both the leaves. Shake off any soil from the leaves. Dry both the leaves A and B by placing between blotting paper. Draw the out lines on graph paper, marking any holes that have appeared. compare the area of each leaf with its original area. Replant the two leaves in their respective pots and repeat the above procedure at 2 week intervals till there is a clear difference between the two leaves.
