117 Effect of organic liquid fertilizer and municipal waste compost leachate as compared with humic acid on soil physical and chemical properties Fatemeh Beheshti F beheshti@ag iut ac ir Department of Soil Science Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor H Shariatmadari Shariatmadari@cc iut ac ir M Shirvani Shirvani@cc iut ac irAbstractSoil organic matter content is an important indicator of soil quality with a great impact on soilcharacteristics and plant growth parameters Application of organic fertilizers or organic residues is anormal practice to amend the soil organic matter level Organic liquid fertilizer and municipal wastecompost leachate as organic amendments playing a role similar to humic acid in soils The present studywas conducted to investigate the effect of an organic liquid fertilizer and a municipal waste compostleachate in comparison with a commercial humic acid on some physical and chemical properties ofdifferent soil textures under corn Zea maize single cross 704 cultivation A factorial arrangement basedon a completely randomized design with three replications was conducted in a research greenhouse atIsfahan University of Technology The experimental organic amendments were an organic liquidfertilizer extracted with 0 5 M KOH from Isfahan municipal waste compost the municipal waste compostleachate and a processed humic acid extracted from an Iranian leonardite The organic amendments wereapplied at two levels as zero and one percent of organic carbon 10 g organic carbon per Kg of soil Three soil textures as clay loam loam and sandy loam were examined The loam and sandy loam textureswere made up by topping pure sand particles to a clay loam sample The results showed that organicamendment treatments increased the electrical conductivity organic carbon and the cation exchangecapacity of the soils while decreased bulk density and water dispersible clay of the soils Also all soilmeasured properties except nitrogen content were increased under corn cultivation as compared with thenot planted soil The organic amendments by improving the soil physical and fertility aspects increasedthe plants height and stem diameter while decreased the calcium and manganese concentration of theplants This decrease may be due to the competition effects of some nutrients that is loaded to the soil bythe amendments Finally it could be concluded that the effects of the organic amendments on soil weredifferent based of the soil texture and the presence of plant while the organic liquid fertilizer andcompost leachate more improved the soil quality and plant yield parameters as compared with theexamined humic acid sample Keywords Humic acid Organic liquid fertilizer municipal waste compost leachate Corn plant Soil quality
