Abstract:

Pollution is becoming a serious problem in agricultural regions; organic farming is an agricultural practice that rises plants specially vegetables and fruits without the use of synthetic pesticides, herbicides, fertilizers, or plant growth regulators. In Jordan the interest for organic farming was increased recently. A plastic house experiment was carried out during the 2008/2009 season, to compare the effect of four fermented organic matter sources (cattle, poultry and sheep manure in addition to 1:1:1 mixture of the three organic matter sources) in which 4 kg organic matter/m² were used, with that of the conventional fertilizer and control treatments on micronutrients and heavy metals accumulation in soil, using a randomized complete block design (RCBD) with four replicates. After organic matter fermentation results showed that the sheep manure contains the highest amounts of Fe, Mn, and Pb, while cattle manure contains the highest amounts of Zn, and Cu. Otherwise the highest amount of Ni and Cd were obtained by the mixture of the animal manures, but the addition of sheep manure to the soil increased the amount of Fe, Cu and Mn. Soils amended with cattle manure contained the highest amount of Zn. Otherwise manure mixture amended soil contained the highest amount of Pb and Ni. On the other hand the highest amounts of Cd were the same in the soils amended with cattle, sheep and manure mixtures. At the end of the experiment, the highest iron content was found in the conventionally treated soil, while control treatment produced the lowest soil content of zinc, copper and lead. On the other hand the highest cadmium was found in the poultry manure-treated soil.
