A method for making a field for sports activities comprises the step of feeding raw material based on coconut to milling means (11). Here the material (10) is milled and, on the one hand, a certain amount of longer fibres are obtained that are withdrawn, and on the other hand, a certain amount of short and medium fibres are obtained, hereafter indicated generically as raw material based on ground coconut (15). The raw material based on ground coconut (15), having a heterogeneous granulometry, is loaded by a hopper (12) on a conveyor belt (20) for being fed in a sieve. In the sieve (32) the separation is obtained of the powder part (16) from the granular and fibrous parts (17). The latter are sent by a conveyor belt (22) to a storage reservoir (43) and from there sent towards processes for making loose material to provide substrates for sports activities.
