Corrects copper deficiency in soils such as sandy or peaty soils.

Copper is said to be deficient when it is least available to plants. This is due to the presence of highly organic soils, or after excessive applications of lime or dolomite which raises the pH too high. Plants grown with high levels of nitrogen, especially in the ammonium form, require addition of copper due to its limited availability.

Symptoms of copper deficiency vary considerably between plant species; however, they generally appear in the youngest leaves first. These symptoms may include yellowing of young leaves with green spots remaining at the ends of veins; the young leaves are rolled inwards or curled; rows of spots of dying tissue sometimes appear; tip death is followed by the formation of numerous weak shoots. Young leaf stems may also become shortened, distorted, and twisted, flowers become paler than normal, small, and misshapen.

Copper deficiency can be corrected by raising the pH value of very acidic soil to 5.3 which increases the availability of the copper. However, at higher pH values the availability of copper decreases again. The application of Searles Bluestone can also correct copper deficiency by simply following the directions below.

– Copper deficiency can occur in all types of soils, particularly in sandy or peaty soils.
