Cow Dung Pit

We have been practising biodynamics in our vineyard since 2007. Our initial phase was to apply Preparation 500 throughout the vineyard and orchard.

In 2008, we set up our first cow dung pit. We obtained the cow dung from a neighbour who was also organic and biodynamic. Once we had obtained enough cow dung, we dug a hole 1 metre by 1 metre and 30 centimetres deep. We set in a frame for the hole and pegged the corners. It is important to use untreated wood or natural hardwood to avoid the leaching of chemicals into the manure.

Once the hole was completed and framed, we placed the cow dung in it and then added the five sets of biodynamic preparations 502–507, pressing them in to thumb depth at around 20 centimetres apart. The valerian preparation 507 is mixed with water and then poured over the pit.

Over the pit, we placed a sack to help retain the moisture, along with a wooden lid. It is also important to use untreated materials for the pit. After several months, the cow dung breaks down into compost. This preparation can then be used in conjunction with Preparation 500, or on its own, and applied to the vineyard.

In New Zealand, biodynamic certification is provided by Demeter. Our vineyards are certified organic through AsureQuality.

Below is a video showing how to make a biodynamic cow pat pit using cow manure. We have created a series of videos on our Wrights Vineyard & Winery YouTube channel , including making biodynamic Preparation 500 using cow horns and making organic seaweed compost and fertiliser teas for plants. We will also be adding more tutorials on organic farming, winegrowing and winemaking.
