The alpaca is a ruminent with three stomachs. It converts grass and hay to energy very quickly, eating far less (as a percentage of its body weight) than other farm animals. Alpaca manure is lower in organic matter content than the manure from most other barnyard livestock (cows, horses, goats and sheep) but still has enough to improve soil texture and water-holding capacity. This lower organic content allows alpaca manure to be spread directly onto plants without burning them. It is the decomposition of organic matter content of the manure that indicates their efficient digestion system.
The nitrogen and potassium content of alpaca dung is comparatively high, an indication of good fertilizer value. Nitrogen, phosphorus and potassium are the major plant nutrients. Phosphorus is relatively low as in most livestock manure. The calcium and magnesium content is about average. South American Indians use the alpaca waste for fuel, and local gardeners find the alpaca's rich fertilizer perfect for growing fruits and vegetables. A herd of alpacas consolidates its waste in one or two spots in the paddocks, thereby controlling the spread of parasites and making it easier to collect and use on our garden beds.
