WHY MODERN PLANT NUTRITION CREATES ANTAGONISM By using a balanced, high-quality, specifically formulated nutrition system, plants can maximize their genetic potential. The plants get into wild swings of deficiencies and lockout which results in decreased yield and quality. Unless a grower has a serious scientific bent, this practice often results in overdose and deficiency of specific nutrients. These problems often arise when growers attempt to create their own ‘custom’ nutrient recipe, mixing different product lines from different companies. Optimum nutrition is achieved by balancing the nutrients in the medium. At the same time, it also limits the uptake of zinc, iron, and copper. If there’s excess phosphorus it increases the plant’s nitrogen uptake, unbalancing the nutrition. Most nutrients usually work together, but this is not always the case. Understanding nutrient antagonism makes diagnosing deficiencies and excesses more difficult, but ultimately more accurate. This list shows which elements react with each other. The antagonistic action of nutrients shows how overdoses of certain elements can lockout or displace another element. The salts are the most common cause of tip burn, nutrient antagonism, and weak plant growth. Many modern synthetic fertilizers primarily contain nitrates or other salt-based forms of nitrogen. That’s why it’s better to use organic nitrogen instead of inorganic nitrogen, which is high in nitrates. Nitrates ‘push’ calcium away and can block absorption. Not all deficiencies are caused by a lack of nutrients! For example, calcium deficiency may be diagnosed due to low calcium levels OR because there are high levels of nitrates (NO3). If you don’t understand these interactions, you may over-supplement with a specific nutrient in an attempt to correct a deficiency. ![]() It is very important to understand how certain nutrients react with each other. ![]()
