You may see this fine piece of machinery operating on the golf courses from time to time. This state of the art Toro 5800 sprayer allows us to make precise applications of fertilizer, particularly the ultra-efficient foliar applied fertilizer. True foliar fertilizers are applied to the plant as liquids and actually absorbed into the plant through the leaf, as opposed to older technology fertilizers which employ far more wasteful methods of root uptake. The plant needs the same nutrients we humans utilize and ingest on a daily basis...magnesium, potassium and calcium. Because this process is far more efficient, we can reduce the amounts of fertilizer that are used.
