The Basics of Fertilizer Calculations for Greenhouse Crops

Abstract

Fertilizers are designed to provide the elements necessary for plant growth. About 90% of the plant weight is made up of water. The remaining mass constitutes the plant dry weight, which is made up primarily of 17 elements that are required for plant growth. Explains how to properly determine the amount of fertilizer required for making a stock solution and how to check the calibration of a fertilizer injector.
