Essential micronutrient required by plants in small quantities
Involved in photosynthesis, seed set and flowering
Deficiency symptoms include distorted leaves, twisted stems and blind grain sites
Copper losses are minimal due to its ability to bind to clay soil particles
Best applied to the soil at crop establishment to actively prevent copper deficiencies
MICRO-MATCH copper can be coated onto any one of Origins 13,000+ grades
Copper is available for plant uptake in its ionic form (Cu2+). Its positive charge means it is able to bind to negatively charged clay particles and organic matter within the soil, therefore soils with a high clay content tend to have higher levels of copper.
Because of the ability of copper to form strong bonds with soil organic matter, peaty soils or soils with more than 5% organic matter can contain large amounts of copper which is unavailable for crop uptake, leading to an induced deficiency.
Like many other micronutrients, copper becomes less available at a high pH (<7) and so fields which have received large applications of lime can be vulnerable to deficiency.
Soils high in iron, molybdenum and sulphur are likely to induce copper deficiency.
Copper deficient plants have distorted leaves and bent and twisted stems. Affected plants have blind grain sites and distorted ear.
An early signs of copper deficiency is chlorosis (yellowing) of younger leaves.
A Broad Spectrum (BS) soil analysis can help determine the quantity of copper which is likely to be available for crop uptake and can be used to tailor fertiliser plans and to help prevent deficiencies within the season.
Tissue analysis is considered unreliable in determining the concentration of copper within the plant.
Copper is less prone to leaching losses due to its positive charge and its ability to bind to clay particles. Losses will be greater in soils with a low clay content.
