In a country like Iran, where soil organic matter is less than 1% and in most cases even less than 0.5 %, Municipal solid waste (MSW) is a permanent and inexpensive source of organic matter. Various experiments have indicated that applications of compost improve plant health, yield and nutritional quality. However, the quality of the compost determines the growth and the development of plants. ...

Soil water content is one of the most important parameters for estimating irrigation frequency and providing the plant’s water requirement. Since measurement of soil water content is both expensive and time consuming, water movement models are used to estimate these values. In this study, LEACHW model was used to estimate soil water content for two “dry” (20-29 Aug) and “wet” (1-6 Jul) periods ...

ABSTRACT- To evaluate effects of different soil moisture conditions namely, phosphorus (P) and zinc (Zn) application, on extractable Zn and Fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. The first experiment was performed with the following factors; incubation time at four leve...

Middle and southern Iraq suffers from polluted soils due to crude oil, spilled on land, leakage from transmitting pipe networks, or petroleum products from refineries. Many researchers have studied pollution impacts on the soil in details, but there is a clear lack of investigation on the influence of crude oil on soil erodibility. Recent researches have investigated the influence of pollution ...

results the soil was largely composed of silt and clay (silt:41 - 42%, clay: 40 - 43%, sand: 15 - 18%). the average moisture content of the saturated soil was 12.96%,; average electricity conductivity was 18.64 dsm-1; average ph of the paste was 8.36; and average percentage of organic carbon was 0.19%. result of the laboratory analysis reported the average content of total nitrogen as 0.026%, p...
