Macro nutrients are those elements which you find in quantities greater than 0.1% of the dry matter. The three main elements are:

Carbon, Hydrogen and Oxygen are found in air and water. Other elements need to be added as mineral elements.
A plant producing fruits or vegetables needs to replace the macro nutrients used to produce those fruits or vegetables. For such plants a regular provision of macro nutrients is therefore necessary in order to obtain the best results. Without those macro nutrients a plant will stop growing, show huge deficiencies over time or stop producing any fruits or vegetables.
Our organic fertilizer Chai contains high levels of Macro nutrients particularly Phosphorous and Calcium.
