What are micro-nutrients?

The micro-nutrients, also known as trace elements that are required for healthy plant growth are calcium, magnesium, sulfur, boron, cobalt, copper, iron, manganese, molybdenum and zinc. When deficient in any or all of these elements plants suffer stress, disease, become more susceptible to pest, fungus' and bacteria, and may have uptake issues with the N-P-K fertilizer they are being fed. At best, they will never live up to their genetic potential in growth and yield; at worst, they die. In the case of food crops, nutrient deficient plants lead to nutrient deficiencies in the people and animals who consume them. Due to years of over farming the same fields much of today's commercially produced food has a nutrient level barely exceeding waxed fruit. No surprise that more and more people are choosing to grow the food their families eat in their own gardens. When growing in soil remember to renew the dirt between plantings and when growing hydroponically know that it is absolutely essential to use a hydroponic fertilizer that provides all the trace elements.
