Application of Compost Leachate and its Effect on Absorption of Soil Cadmium by Plants

This study in order to evaluate the effect of using Compost leachate on the density of soil iron in form of a statistical pattern called ʹʹSplit Plotʹʹ by using two main treatments, one subsidiary treatment and three repetitions of the pattern in a three month period. The main N treatments include: irrigation using well water as a blank treatments and the main I treatments include: irrigation using leachate and well water concurrently. Some subsidiary treatments were DI (Drop Irrigation) and SDI (Sub Drop Irrigation). Then in the established plots, 36 biannual pine and cypress shrubs were randomly grown. Two months later the treatment begins. The results revealed that there was a significant variation between the main treatment and the instance regarding Cadmium increase in the soil which was related to the amount of leachate injected into the soil. After some time and using leachate the pH level fell, as much as 0.46 and also due to the great amounts of leachate, the average cd in the soil show a 0.12 mg/kg increase. The underneath drop irrigation ends in better results than sub drop irrigation since it keeps the soil texture fixed.
