Alnus acuminata - Andes alder

Description and Uses

Alnus acuminata (Andes alder) is a tropical tree from Andes . It is mainly grown for its conservation crops , which have a short shelf life. The crop is harvested by total removing. It starts flowering after 0 - 0 years. The yield will be {missing data}, but in its top season there will be a yield of {missing data}. Other crop types include; fodder, mulch, fertilization, timber, fuel, . The {missing data} is used as inedible . The {missing data} is used as " {missing data} " with {missing data} ({missing data} - {missing data}) as its significant phytochemical. There is {missing data} extracted by {missing data} from the tree's {missing data} yielding {missing data} - {missing data} oil. The tree's wood is called {missing data} and has a density of 340 - 600 kg/m³. Regarding firewood production the tree's growing speed is fast, it's energetic value is 4600 ckal/kg and the wood's drying speed is {missing data}. After 9 years the tree can be totally removed as it reached its commercial and ecological goal. Alnus acuminata has a lifespan of 50 years.

Environmental limitations
