English Abstract

A field experiment was conducted in Hout research station- The General Commission for Scientific Agricultural Research-, located in the south of Syria (Al-Swaida Governorate) over the period from 2015 to 2020 -and still on going- to study the effect of adding different levels of organic amendment- Compost of town refuse- on some soil physical properties (2015- 2017).

Then studying the soil capacity to preserve changes after stop adding the organic additions (2018- 2020) to a heavy clay soil.

The results showed several positive changes of all tested organic levels, although the treatment (T1; the highest level of compost 80 ton/h) of adding dry compost was the best on all studied indicators, and improved soil content of organic carbon by 442% in 2017 and with 243% at 2020 after three years of stopping the amending procedure.

A desirable decline in soil bulk density of 31% and 22%.

In addition to a positive increase in soil moisture content at field capacity with 15% and 8% , in soil content of total available water with 96% and 54% .

And raising the capacity of soil carbon sequestration potential with 275% and 167% at the same dates respectively.

While insignificant changes were detected with mineral fertilizer in T4 treatment in compare with the control.
