In this study, the effects of vermicompost on soil chemical
and physical properties
was
evaluated in tomato (Lycopersicum esculentum var
Super Beta) field. The experiment was arranged in a
randomized complete block design with four replications.
Different amounts of vermicompost (0,
5, 10, 15 t ha-1) were incorporated into the top
15 cm of soil. The soil sampling and measurements carried
out 3 months after the application of vermicompost in soil
and the soil samples were collected from depth of 15 cm.
The results showed that addition of
vermicompost at rate of 15 t ha-1 significantly
(P < 0.05) increased contents of soil
total organic carbon, total N, P, K, Ca, Zn and Mn
substantially compared with control plots. The soils treated
with vermicompost had significantly more EC in comparison to
unamended plots. The addition of vermicompost in soil
resulted in decrease of soil pH. The physical properties
such as bulk density and total porosity in soil amended with
vermicompost were improved. The results of this experiment
revealed that addition of vermicompost had significant (P <
0.05) positive effects on the soil chemical, physical
properties.
