The Micronization technology behind Herbagreen is a unique technique through which a rock mineral is micronized and activated. The micronized rock mineral particles are characterized by a higher reactivity and a surface that is 300% more active than a particle delivered through a mechanical milling process.

VitaFlora has been developed after 20 years of research and development, including seven years of intensive trials. Presently the product is being used in large quantities and with excellent results by vegetable, flower and fruit growers as well as home gardeners. The product is a complete fertilizer and soil-conditioner suitable for both commercial and domestic markets. Read more about the process behind VitaFlora.

Foliar fertilizer on plants

“Roots are leaves in the ground, and leaves are roots in the air.”– Alan Chadwick

While it is true that the major elements nitrogen, phosphorus and potassium (NPK) are more economically supplied in solid form, some experts believed that it was only the quantity of these that counted. However, the mere presence of a particular chemical element in the soil does not guarantee the effective assimilation of mineral fertilisers by plants. Nutrient demand curves indicate stages in a plant’s life-cycle when the need for some nutrients may be greater than the plants physiological capacity to supply itself, even when these soil nutrients are abundantly available. Highly soluble potassium and nitrogen-based fertilisers can be easily washed out from the soil, and phosphate fertilisers can attach themselves to ions of potassium, magnesium, aluminium and iron into a chemically insoluble form for plants.

Foliar nutrients on the other hand are mobilised directly into plant leaves, which is the goal of fertilization to begin with, increasing the rate of photosynthesis in the leaves, and by doing so stimulate nutrient absorption by plant roots. Foliar fertilizer used in conjunction with solid fertilizer, can be used to quickly correct a nutrient imbalance and stimulate increase in root uptake. This does not mean that foliar fertilizer replaces solid fertilizer, but the use of foliar fertilizer has been shown to increase the availability of the applied major elements, that have been applied in solid form.

Applying Foliar fertilizer on plants

By applying a foliar fertilizer directly to the leaf, it increases the activity in the leaf, at the same time increasing chlorophyll and thus photosynthesis. By increasing photosynthesis, we increase production and efficiency. The increased efficiency can reduce the need for soil applied fertilizer, which reduces leaching and run off of fertilizing nutrients.

Excess carbohydrate produced by the plant, due to greater synthesis of sugars by the increased chlorophyll, are excreted by the root hairs which stimulate microbial colonies on the root by providing additional energy sources. The bacterial colonies in turn provide auxins and other root stimulation compounds. More root tissue and root hairs increases the plants ability to take up water and fertilizer ions. The aim of fertilization is the same for both soil applied as well as foliar applied, but it is, in fact 8-10 times more effective to foliar feed a plant as far as the amount of nutrients required and the speed with which those nutrients were utilized.
