Biochemical and anatomical aspects of copper deficiency
Copper (Cu) is an essential mineral element for plants, playing a role in cellular metabolism, associated with photosynthesis, production of proteins and lignin, and activity of the antioxidant system (Alloway 2013).Therefore, Cu should be adequately supplied by crop fertilization in agricultural systems (Yruela 2009; Shabbir et al. 2020).. …

So, the citric acid chelated copper is readily available to plants. Application rates for copper chelate can vary according to your circumstances. If you have a 4% copper chelate solution, just 3-4 tsp per 1000 sq ft every 4 to 6 weeks applied to plants provides sufficient copper. If you prefer to apply it to soil, use 4-6 tsp per 1000 sq ft.

A wide variety of plant and animal foods contain copper, and the average human diet provides approximately 1,400 mcg/day for men and 1,100 mcg/day for women that is primarily absorbed in the upper small intestine [1,2,7-9]. Almost two-thirds of the body's copper is located in the skeleton and muscle [1,3].

Copper: Helpful or Harmful for Plant Health?
Copper is one of the essential micronutrients, or trace minerals, that plants need for growth. As with any nutrient, plants can absorb and use only certain forms of copper. For example, copper metal is useless to plants, but once dissolved in acidic conditions, copper enters plants very easily. Under high pH conditions (alkaline) copper becomes ...
