Title

THE SIMPLE AND COMBINED EFFECTS OF ORGANIC AND MINERAL AMENDMENTS ON AGGREGATES SIZE OF THE SALIC SODIC SOIL WITH SILT LOAM TEXTURE

Pages

  169-178

Abstract

 Soil structure and aggregate stability affect soil erodibility. There is a necessity for increasing aggregate stability against erosive factors such as wind and water. This study was conducted on surface soil samples (0-20cm) collected from agricultural land susceptible to erosion located in Chahoo, southeast of Fars province. The experimental design was CRD with 10 treatments and was replicated 3 times as follows: control plot (without addition of soil amendments), pure GYPSUM, chopped wheat straw, farm yard manure, GYPSUM + wheat straw, GYPSUM + farm yard manure (1% w/w), CEMENT at levels (0.3% w/w), (0.6% w/w), (0.9% w/w), GYPSUM + CEMENT (0.9% w/w). After one, four and seven months, the amounts of soil AGGREGATES in 53-4000 µm sizes were determined by wet sieving and MWD was calculated. The results of aggregate size distribution in every stage of the experiment showed that application of farm yard manure and wheat straw separately or in combination with GYPSUM through reduction in AGGREGATES with diameters of <106 mm has caused an increase in AGGREGATES with diameter of >106 mm. Based on the results of this research, the effect of these treatments, which increased MWD of the aggregate, results from the amount of AGGREGATES with diameters larger than 1000 mm. According to the results of this study, it is suggested that these treatments be considered suitable to increase the stability of sensitive silt loam soils.
