INTRODUCTION
Calcium nitrate is a highly soluble nitrogen fertilizer that supplies both calcium and nitrate nitrogen to crops. It is widely used in fertigation systems, greenhouse production, and high-value crops. Understanding the compounds and composition of calcium nitrate is essential for proper fertilizer selection and balanced plant nutrition.
WHAT IS CALCIUM NITRATE
Calcium nitrate is an inorganic fertilizer compound containing calcium and nitrogen in nitrate form. It dissolves easily in water, making it suitable for both soil and foliar applications.
CHEMICAL COMPOSITION OF CALCIUM NITRATE
The composition of calcium nitrate includes:
-
Calcium in soluble form
-
Nitrogen primarily as nitrate
-
Low impurity content
