Nutrient Deficiency and Toxicity

A wide variety of problems can effect plant growth and health. Much of the information on this website describes diseases but this section is devoted to problems associated with either excess levels of nutrients in the soil which leads to toxicity, or a lack of nutrient within the soil which leads to deficiencies within plants. The relationship between soil nutrient levels and plant nutrient levels is complex. The ability of a plant to absorb any given nutrient is affected by pH, temperature and moisture as well as the amounts of other nutrients within the soil. For this reason, it is important to correctly diagnose symptoms of deficiency and toxicity before taking corrective action otherwise you risk solving one problem only to create another one. The information in this section of the website will help you identify nutrient deficiencies and toxicities in your plants and provide you with some tools for preventing and treating these problems.
