Dino Selenium

Dino Selenium is a mixture of a high soluble calcium granulate, enriched with Selenium granules. This mixture ensures that the calcium mixed with the selenium can be evenly distributed across the field. The selenium sources in this product are partly a rapid-acting component and partly a slow-acting component; especially the latter form works slower, such that one application in the spring increases the selenium content in the grass, maize or other crops throughout the season. These two components ensure that the selenium absorbed by the plant is converted in the grass or maize into an organic Selenium. This organic selenium is readily available to the animal and helps prevent selenium deficiencies.

Dino selenium also has a proven effect on reducing damage caused by wireworms and grubs.
