FERTILIZER GUIDE

          

Grapevine belongs to the Vitaceae family, comprising nineteen genera among which we can highlight the genus Vitis. Vitis is native to warm or temperate zones of the Northern Hemisphere (America, Europe and Asia), where most common varieties are grown. 

Vitis vinifera table grapes can be in the form of either seeded or non-seeded varietals and range widely in terms of colour, size, sweetness and adaptability to local growing conditions.

Climate: Grapevine is a plant of a temperate climate, this situation allows them to go through a period of vegetative activity and another one of winter rest. The temperature from which activity starts, is at an average value of 10 °C. The temperature range 20-25 °C is optimal for growth processes, withering and maturation. Above 42 °C, drying out and burns of leaves and clusters may occur.

Soil: It has wide adaptability to most of land for agricultural use. There are three growth-limiting factors: salinity, limestone excess and high levels of clay.

Nutritional requirements

N, P, K, Ca, Mg and S are considered essential elements for grapevine as macronutrients and Mo, Cu, Mn, B, Zn and Fe as micronutrients.

Foliar fertilizers

Foliar fertilization is the fastest and most effective method to supplement and enrich plant nutrition and to correct nutritional deficiencies when needed. This contributes significantly to higher and better quality productions.

Potassium, Calcium, Zinc and Boron are also applied via foliar. Lima Europe has a wide range of foliar fertilizers and special products for foliar application.

To verify the safe rate under local conditions, it is advisable to spray recommended rate on a few plants. After 3-4 days check the tested plants for scorching symptoms.
