Definition - What does Macronutrient mean?
A macronutrient is used to promote fertility in garden soil while helping flowers, vegetables, and fruits to grow as productively as possible. Soil does not normally include all of the nutrients and minerals, hence the importance of adding macronutrients to the gardening plot.
Macronutrient mixes commonly include some of the most important elements for gardening, such as potassium, phosphorus, and nitrogen. Silicon, sulfur, magnesium, and calcium are the other secondary macronutrients that are added to gardens.
MaximumYield explains Macronutrient
Each macronutrient plays a unique and essential role in promoting plant growth and flowering. Silicon, for example, has been known to provide plants with more drought-resistance because it creates a waterproof exterior on the cells. Silicon can also encourage certain vegetables to retain more water than they normally would without additional macronutrients. Nitrogen has been known to balance the core functions of any plant. It also enhances leaf color and growth. Plants that are lacking in nitrogen are often recognized by the rapid yellowing of their leaves.
Macronutrient mixes are often added to garden patches that suffer from various types of malnutrition. Macronutrients are available in powered or liquid form.
