Definition - What does Micronutrient mean?
In gardening, micronutrients contribute widely to plant nutrition by providing seven essential nutrients that plants require to maintain productive growth. These nutrients include chlorine, molybdenum, copper, iron, manganese, zinc, and boron. Horticulturalists normally add micronutrients to their plants only if they exhibit signs of deficiency.
MaximumYield explains Micronutrient
To determine whether plants actually require micronutrients, horticulturists may first try to determine if the growth deficiency is related to other issues such as insects, droughts, or salinity. In several cases, soil samples are also taken for analysis. If the plants are found to lack the seven essential nutrients, they are administered small doses of micronutrients at a time.
One particular micronutrient that is extremely important for plant growth is boron. This directly affects germination, pollen formation, and flower retention. Plants that are low in boron can display hollow fruits and stems as well as barren ears.
Iron is another micronutrient essential to healthy plant growth. This nutrient actively encourages the production of chlorophyll and prevents the leaf discoloration that is commonly found in dying plants. When treating crops with micronutrients, it is advisable to refrain from overusing glyphosate because this prevents the plants from absorbing the nutrients.
