Summary in the original language of the document

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.

EPrint Type:	Practice tool
Teaser:	Compost tea: manage soil fertility in organic farming.
What problem does the tool address?:	The problem addressed is to efficiently manage soil fertility and crop production quality, at the same time solving residues and by-products disposing problems.
What solution does the tool offer?:	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.

Additional Publishing Information:	This practice abstract was elaborated in the frame of the OLTRE.BIO project (PSR Puglia - Misura 16 Cooperazione Sottomisura 16.2 Sostegno a progetti pilota e allo sviluppo di nuovi prodotti, pratiche, processi e tecnologie). The project is running from August 2020 to February 2024, and is to contribute to manage soil fertility, in organic cherry orchards and vineyards, by using green manure, compost and compost tea produced on-farm. https://feder.bio/progetti/oltre-bio/
