Nutritional Content of Air-dried Cow Manure

• Pellets are much cheaper to transport. The final volume of pellets you get from a given quantity of cow dung is usually 50 – 80 % of the original compost. By further compressing these pellets you can reduce their volume and that way enhance their transportability.
• The resultant compactness of the pellets ensures you will require less storage space for this fertilizer during the off season.
• Pellets are quite suitable for mechanized spreading since they are comparatively uniform in quality and size, they can be applied using various kinds of machinery that you might already be having.
• Pellets do not generate dust thus you can freely spread them to areas of your farm that are just next to your residence.
