Precision Viticulture Programme for Vineyard in Manavi

Precision Viticulture was pioneered in Australia and the United States over the past fifteen years. Like its sister methodology, Precision Agriculture, it uses a mixture of soil scanning, aerial imaging, targeted soil and tissue testing, GPS-enabled fertiliser application equipment, and intelligent irrigation design, to enhance yield and quality while reducing waste and excess cost from production. Winemakers in Australia and the United States report that correct utilisation of the suite of techniques increases their wine sales income by over USD$20,000 per Ha, with production cost changed very little.

This season we will be testing soil on a 110 ha vineyard in western Kakheti’s Manavi village prior to the spring application of fertiliser, followed by petiole (vine tissue) testing later in the season to guide the vigneron in what subsquent fertiliser will be needed later in the vine’s production cycle for acceptable yield and quality at the lowest possible cost. The vineyard is supplying a large, well-known winery in Kakheti with grapes for table wines.

Later in the season EMI (Electromagnetic Induction Imaging) performed by our British geophysical partners will provide precise information on soil water holding capacity and composition for every square metre of the property. This will guide us in developing irrigation management zones and location of irrigation line valves, to ensure that vines receive exactly the right amount of water at the right time. Too little, and yields suffer, sometimes calamitously. Too much, and concentration and quality are affected. We use intelligent design (assisted by our Australian engineering partners) and objective measurement with soil moisture sensors to keep vine hydration in the “Goldilocks” zone for optimal yield and quality.

Use of aerial imaging by our Italian contractors is of further use at veraison in scheduling time of harvest for different parts of each land plot. Vigour and stage of maturity commonly varies greatly within each plot, making pre-determination of what to harvest when a useful technique. By doing so, grape quality can be dramatically enhanced in less vigourous parts of the vineyard, and profits increased.

Tissue Testing: Precision Agriculture programme on 2500 Ha of cereal cropping land

This month we will be testing over 2500 Ha of estate as part of our Precision Agriculture programme; tissue testing of wheat and barley crops to guide the farmers on how much additional fertiliser to add in March to crops, and soil testing to plan for late spring plantings of sunflower, mungbean, mustard and canola. Solid NPK and micronutrient will be laid down at seeding.

By engaging in targetted soil and tissue testing, matched with GPS-enabled datalogging and division of farms up into management plots, we can exactly match nutritional requirements of plants with fertiliser application suitable for the growth phase of the plant and the soil in that part of the property. This results in superior yields and quality parameters, while keeping fertiliser costs as much as 30% below that of conventional  blanket regimes.

We work closely with a US laboratory partner to ensure international standards of accuracy.

We will post pictures and video over the next few weeks to demonstrate how this programme operates.
