For the vine to develop optimally there has to be a balance in the mineral compounds in the ground. The quantity of nutrients that a vineyard needs is variable and depends on the vegetative state it is in – both too much and too little can be harmful. Trends:

• Subterranean drip irrigation reduces losses through evaporation or vandalism, and prevents the material being damaged by animals or insects.
• The modern drip irrigation facilities do not impede farming and harvesting jobs.
• The drip-feed piping forms part of the first wire of the row of vines.

Benefits:

• The water and the fertilizer are located where the plant needs them.
• The nutrient elements are dosed in a balanced way.
• You can fertilize with small doses of water, since climatic factors, such as bad weather, wet ground, etc., are not so decisive.
• The assimilation of nutrients is maximized through being localised in the area of greatest development and root absorption.
• It allows slightly saline water to be used.
• In arid climates it allows a better management of the plantation, of the end production and of the final quality.
• It optimizes the yield of the operation, which signifies greater production.
• It improves crop quality.

The XILEMA vineyard fertigation equipment

• The Xilema automatic units carry out the dosing of fertilizers in the irrigation water with pH control and measurement of the EC, producing a balanced and uniform delivery of nutrients.
• Xilema offers solutions for all needs: farm size, number of sectors, number of fertilizer deposits, etc.
• Xilema has alarms for pH, EC, cuts in electricity supply, maximum and minimum pressure.
• It maintains a historical record of the functions carried out.
• It allows connection to a computer.
• There are different Xilema models to satisfy every need.

The combination of drip irrigation with fertigation and other production factors (density, variety, conduction, loads, etc.), results in a balanced performance and an ideal oenological quality for obtaining highly appreciated wines.
