The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs.
It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
Pularin:
Foot ball shaped 60 atoms of carbon at edges is layed in pularin.Pularin atoms are arranged in ball.
Each atom is called Bucky balls and tubes are called Bucky tubes or Nano tubes.Each nano tube is 1 to 7 nm diameter i.e 1nm=50000 part of a hair sting.
