Match the following columns:

Column I (Chemical)	Column II (Use)
a. Sodic soil	1. lllite
b. Herbicide	2. N-serve
c. Fruit ripening	3. 2, 4-D
d. Nitrogen fixing inhibitor	4. Ethalene

Solution(By Examveda Team)

Sodic soil means the soil is rich in sodium ions, sodium salts are leached through the soil and some sodium remains bound to clay particles and illite is the group of closely related non-expanding clay minerals.
2, 4-D is the Herbicide that controls broadleaf weeds.
Ethylene in gaseous form is used to initiate the ripening process in the fruits, which can be referred to as artificial ripening.
N and -serve is a nitrogen stabilizer and it inhibits nitrification, which helps to optimize the yield and profit potential of corn and wheat.
