Copper (Cu) is a micronutrient which is only needed in trace amounts, but is involved in several key plant actions, including photosynthesis, nitrogen utilization, protein production and water regulation. Copper deficiency is becoming more widespread across Western Canada, limiting a crop’s growth and reducing yield potential. In this post we will examine the role of copper in the plant, consequences of copper deficiency and solutions to provide cu to your crop.
Broadcasting fertilizer is a practice commonly used to maximize soil fertility, with advantages for managing the seeding operation early in the spring. However, this practice is detrimental to the efficiency of phosphorus, as it exposes it to either run-off in wet springs or, early tie-up or both. In this post we will examine the factors that can impair or improve phosphorus availability for uptake by plants.
