How much copper is too much for plants?

Copper toxicity to roots could occur when total Cu exceeds 50 ppm in sandy soils up to 150 ppm for silty-clay or clay soils. Soils higher in organic matter have a higher toxicity cutoff (i.e. allows for higher Cu soil test levels without measurable root toxicity).

Is copper bad for tomato plants?

What plants are sensitive to copper?

Crops differ in their sensitivity to copper deficiency. Copper responsive crops include oats, wheat and lucerne, whilst potatoes and soybeans are less likely to respond. The inhibition of root and shoot growth is one of the first symptoms of copper toxicity, especially in bean, citrus and maize.

Is copper good for all plants?

Copper is an essential element for plant growth. Soils naturally contain copper in some form or other, ranging anywhere from 2 to 100 parts per million (ppm) and averaging at about 30 ppm. Most plants contain about 8 to 20 ppm. Without adequate copper, plants will fail to grow properly.

What happens if you are copper deficient?
