Alex Gamez, (Vineyard Manager, Stone Tower Winery) will focus on the persistent issue of soil erosion on steep terrain, detailing the practical steps taken to stabilize these slopes, including the use of a 1,200-lb. tandem disk harrow and aerial drone spraying. He will also touch on the adoption of laser bird deterrents and half-track tractors as part of a broader shift toward terrain-adapted vineyard management. - Session V06 | Vineyard Mechanization Update | Eastern Winery Exposition
Traditional tilling refers to the long-standing agricultural practice of mechanically agitating soil to prepare a seedbed, control weeds, and incorporate crop residues or fertilizers. It typically involves primary tillage—such as ploughing with a mouldboard or chisel plow—to invert and loosen the soil to depths of 10–25 cm—followed by secondary tillage (e.g., disking, harrowing) to create a fine, smooth seedbed. This method is commonly known as conventional tillage, where less than 15% of crop residue remains on the soil surface after planting. It is widely used in smallholder and commercial farming, especially where animal-drawn plows or tractors are available. The goal is to produce a weed-free, aerated, and well-structured seedbed that promotes rapid germination and root development. 
However, traditional tilling has significant drawbacks: it increases soil erosion, degrades soil structure, and accelerates organic matter loss. Tillage erosion is a major form of soil degradation caused by conventional tilling practices, where mechanical implements move soil downslope. This erosion is even more pronounced on steep terrain and is a difficulty that Alex Gamez and Stone Tower Winery faced on one particularly plot where trenches that formed became more dangerous for traditional machinery and personnel. Stone Tower Winery farms 93 acres of vines, making it the largest estate vineyard in Virginia's Loudoun County. Managing this large estate is even more complex as the dozens of different grape varieties are planted across multiple terrains. One of these being this steep seven acre plot will be the focus of his presentation in the V06 | Vineyard Mechanization Update session at the upcoming Eastern Winery Exposition.
Alex will present the practical steps that Stone Tower used to stabilize this slope which including changing the machinery and relying on 3rd party aerial drone technology for fungicide and pesticide applications. The powerful and stable half-track tractor navigates both slope trajectories providing safe usage for the team. It enables them to amend the soil more often than once a year and, along with the drone, helps minimize foot traffic on the steep slope. Other challenges that he may mention are their plans to limit harm from the spotted lantern fly as well as the possibility of Pierce's Disease in the vineyard. 
Visitors to the winery will be impressed with the estate's rolling hills and the mountainous backdrop. Also impressive are two wines that winemaker James Phillips vinified from field blends. The first is the Sycolin Creek - a Rhone styled blend of 48% Viognier, 29% Roussanne, 21% Marsanne, 2% Grenache Blanc. Although the Viognier and Roussanne ripen very similarly, the Marsanne is later so the grapes are harvested when the Marsanne is a little under-ripe. The result is a very delicious and interesting wine where five months in French oak provide just enough texture without losing flavor and acidity. Similarly the Cabernet Sauvignon and Cabernet Franc grapes for their Rosé (40% Cabernet Sauvignon, 24% Cabernet Franc, 36% Merlot) are a field blend harvested specifically for a direct press rosé styled wine. The Merlot was barrel fermented and provides fruitiness and texture to this refreshing wine.
