We know that plants require nutrients. If we supply these in excess, will it be beneficial to the plants? If yes, how/ If no, why?

Ans.

A plant can tolerate a specific amount of nutrients only. Even a slightly lesser amount or more of it can cause deficiency or toxicity. It is generally observed that the toxicity of one element can lead to a deficiency of others. For example, in the case of toxicity of manganese, elements like calcium, nitrogen, iron become deficient because when manganese is stored in excess by plants, the calcium is translocated to the shoot apex and deficiency of elements like Magnesium, Iron, and Nitrogen are induced leading to stunted growth or retarded growth of the plant. In such cases, farmers should use these nutrients in their limited concentration as prescribed to prevent any deficiency or excessive intake. Thus, excess of nutrients is never beneficial but harmful for plants.
