Chelated Copper Enhanced With Liquid Humic

Copper plays a role in photosynthesis and respiration. Copper deficiency can result in delayed flowering, maturity and sterility. Some plants that need more copper than other plants include beets, onions, lettuce, spinach and tomatoes. As organic matter increases, available copper decreases. In soils with a pH above 7.5, plant analysis is used to check for copper deficiency. Chelated copper is usually added when another fertilizer is being applied. EST recommends using only one-sixth the amount of recommended in organic copper when chelated copper is used. If a copper deficiency is confirmed, applications are good for five to eight years, depending on the soil and crop. Once a year application is recommended to build up the copper deficiency. Soil should be tested prior to applying copper.

Liquid Humic increases the absorption rate of copper, also makes the chelated copper readily available for plant foliar and root absorption. This can be mixed with other fertilizers before it’s applied.

This will be determined based on soil test and type of crop that is going to be planted.
