Minerals

Mineral nutrients are the food that the crops need to grow and are equally as important as the moisture and growth parameters. FruitLook measures the amount of nitrogen present in the aboveground part of your crop.  Nitrogen is the fuel for your crop and an indication for fertilization. These parameters give an impression of the distribution of the minerals within the blocks.

A total diverse diet for the plant exists of a total of 16 elements that are essential for the growth and full development of crops. When these nutrients are deficient it is impossible for the plant to complete the vegetative or reproductive stage of its life cycle. Such deficiency is specific to the element in question and can be prevented or corrected only by supplying this element. Out of these 16 elements, carbon (C) and oxygen are obtained from the gas CO2, and hydrogen (H) is obtained from water (H2O). 
The other 13 elements are called mineral nutrients because they are taken up in mineral (inorganic) forms. Nitrogen is the most abundant mineral nutrient in plants; 2–4 percent of a plant's dry matter is Nitrogen. It is a part of chlorophyll (the green pigment in leaves) and is an essential constituent of all proteins. It is responsible for the dark green color of stem and leaves, vigorous growth, branching/tillering, leaf production, size enlargement, and yield formation.
When too little Nitrogen is available it will negatively impact the growth rate. N-deficient plants might be shorter, have smaller leaves, leaves become yellow, and look different from the healthy crop you were expecting. In a case of severe deficiency, leaves turn brown and die, this way crop yield will be reduced.
