The problem addressed is to efficiently manage soil fertility and crop production quality, at the same time solving residues and by-products disposing problems.
Solution
To carry out a sustainable valorization of farm wastes (e.g. cover crops residues and pruning residues), at a low cost, by easily producing and applying “compost tea” at farm level.
Description
The compost tea production process involves the use of a bioextractor (containing water), that is a tank equipped with an aeration device (pump). The on-farm compost is placed in a filter bag (hemp or nylon) and soaked in the water. Oxygenation is obtained by activating the recirculation of the aqueous medium of extraction via a pump. The extraction is carried out with a ratio of 1:5 v/v (20%). In order to ensure proper oxygenation, the timer should be set to a value of 15 minutes (on) every 3 hours (off). A further dilution can be necessary, after measuring the electrical conductivity, up to a ratio of 1:15 v/v, before using compost tea in soil (and on crop leaves).
In sweet cherry orchards and in vineyards compost tea must be provided about three times during each season.
