Effectiveness of compost and vermicompost from market organic waste to improve soil chemical properties

The purpose of this study is to evaluate the results of compost and vermicompost derived from market organic waste and its ability to improve soil chemical properties. Seven treatments consisted of treatments without organic matter (control), compost consisted of three treatments (2.5, 5, and 10 tons/ha), and vermicompost consisted of three treatments (2.5, 5, and 10 tons/ha). The treatments were arranged using a Completely Randomized Design with three replications. Each treatment was mixed with soil and incubated for eight weeks. After eight weeks the parameters observed consisted of total N, total P, available P, total K, Organic-C, and pH. The results showed a change in soil chemical content. The highest increase in soil chemical content was shown in the treatment of vermicompost. Application vermicompost 10 tons/ha had a significant influence on changes in soil pH, organic C, total P, available P, total K, and Compost 10 tons/ha increased total N. Vermicompost application of 10 tons/ha could increase total P (215.99%), available P (465.34%), total K (37.78%), pH (12.38%) and organic-C (40.34 %). Compost 10 tons/ha increases total N by (54%). Market organic waste effectively used as vermicompost and compost that could improve the soil's chemical properties.
