B Planting and cultivating strawberry plants
Two strawberry cultivars, Camarosa (June bearing) and Monterey (ever-bearing) have been planted in 80x40x40h cm plastic pots in open air.
Three pots (3 repetition) for every substrate (TS0, TS50 and TS100) have been used.
180 plants (90 Camarosa and 90 Monterey) in 18 pots have been planted in the third week of April 2016, in total.

12. Observations and conclusions
Strawberry Cv Camarosa showed a major vigour, respect to Monterey for each substrate.
Strawberry cv Monterey can allow two harvest time in our environment.
For season 2016 there were no difference between plant cultivated on TS50 and TS100 but the one cultivated on TS0 always had a major vigour.

Year 2017
Substrates have been prepared in February with the same process of 2016.
Cultivation of strawberry will be performed on new substrates at DISPAA and on the two years old sediment at Zelari company with the same cultivar, number of plant and repetition.
Zelari strawberry
Zelari strawberry: TS100 ( )
Strawberry have been planted the 23th of February and the first of March at DISPAA and Zelari respectively.
Data will be gathered every 30 days from plantation; number of buds composing the single plants will be taken into account for a better vigour evaluation.

Let’s starting from the strawberry leaf. Each graphs represent two cultivars, Camarosa and Monterey and in blue the commercial leaf of strawverry plants bought t in nursy plant. First we can see how the 2 cultivars differ in absorbing elements. However, it is possible to see a trend : Leaves on TS100 and TS50 absorb more elements respect leaves on TS0. This happen for Al, Ni anc Cromium with the exception of stronium which have leaves on peat have the greatest absorpium. All these elements are not harmful for plant growth and metabolism

Leaves grown on Ts100 ans Ts50 have more amount of copper and iron.
Manganese is accumulated mostly by leaves grown on TS0.
Zinc was accumulated moslty by commercial leaves.

1)TDI The definition of TDI: is the maximum amount of chemical, element, toxin, expressed on a body mass basis, that can be taken in daily (or weekly) over lifetime without appreciable health risk.
I found all these TDI values for each elements from the Scientif Opinion written by European Food Safety Autority
The TDI for Fe and Mn is missing, because
they are not considered dangerous for human health (EFSA)

Let’s passing to the ntraceutical compounds. We did not find any differences for antioxidant activity and total sugars. On the other hand, frutis grown on TS100 TS50 gained more amount of phenols comparing with TS0.
Probably, the greater amunt of phenols infuits gwotn on sedimetn could be provocke by the precence of stresses for the (probably related to the sediment environemntal condition)

Concerning organic acid, no diferrences in citric and malic acid between treatments. While acrobic acid there were differences: no ascorbi acid for fruit grown on TS100, a small amount for TS50 and greater for TS0.
This could also a response to stress: under stress condition, the ascorbic acid decrease.
