“…This finding is in accordance with the previous studies (Celik et al, 2010;Gulser and Candemir, 2012;Xin et al, 2016). Incorporation of organic matter in clay-textured soils can strengthen the aggregates by weakening cohesion forces and interfering with the formation of crust and large aggregate (Aksakal et al, 2012). The larger amounts of added organic matter may mediate the formation of clay-organic matter complexes, which in fact reduces the penetration resistance on the one hand and protects organic matter against microbial decay on the other hand.…”

Abstract. Soil compaction is a common problem of mineral soils under conventional tillage practices. Organic matter addition is an efficient way of reducing the effects of field traffic in soil compaction. The aim of this study was to investigate the effects of number of tractor passes (one, three, and five) on depth-dependent (0-10 and 10-20 cm) penetration resistance, bulk density, and porosity of clay-textured soil (Typic Xerofluvent) under organic vegetable cultivation practices in the 2010-2013 growing seasons. Fields were treated with farmyard manure (FYM, 35 t ha −1 ), green manure (GM; common vetch, Vicia sativa L.), and conventional tillage (CT). The number of tractor passes resulted in increases in bulk density and penetration resistance (CT > GM > FYM), whereas the volume of total and macropores decreased. The maximum penetration resistance (3.60 MPa) was recorded in the CT treatment with five passes at 0-10 cm depth, whereas the minimum (1.64 MPa) was observed for the FYM treatment with one pass at 10-20 cm depth. The highest bulk density was determined as 1.61 g cm −3 for the CT treatment with five passes at 10-20 cm depth; the smallest value was 1.25 g cm −3 in the FYM treatment with only one pass at 0-10 cm depth. The highest total and macropore volumes were determined as 0.53 and 0.16 cm 3 cm −3 respectively at 0-10 cm depth for the FYM treatment with one pass. The volume of micropores (0.38 cm 3 cm −3 ) was higher at 0-10 cm depth for the FYM treatment with three passes. It can be concluded that organic pre-composted organic amendment rather than green manure is likely to be more efficient in mitigating compaction problems in soil.

“…Among the three soils studied, the maximum changes occurred in soil III that has clay texture. Addition of organic matter to clay‐textured soils may decrease cohesion forces and prevent crust and large aggregate formation (Aksakal et al ., ). Lower PR may be attributed to lower BD recorded in this treatment.…”

Application of organic waste on agricultural land as a soil conditioner and fertilizing material has lately gained much attention. This study was conducted to determine the effects of vermicompost applications (0·5%, 1%, 2% and 4% w/w) on physical characteristics of soils with different textures (sandy loam, loam and clay), under laboratory conditions. The results indicated that in the higher soil aggregate fraction (>12·7 mm) aggregate fraction was limited at the three soils. Vermicompost applications in all three soils significantly increased organic matter content. When compared with control, the increasing rates in organic matter content were 14·0%, 23·8%, 42·0% and 90·2% for 0·5%, 1%, 2% and 4% vermicompost application doses, respectively. Vermicompost applications increased the wet aggregate stability and decreased the dispersion ratio of all the experimental soils in all aggregate size fractions. Overall, wet aggregate stability increased from 26·9% to 52·2% with the application rate of 4%. Correlation coefficient between organic matter content and wet aggregate stability was found as 0·918 ** . The lowest mean bulk density and the highest mean total porosity occurred when the most vermicompost was added. In all the soils studied, the highest permeability coefficients were gained with the application dose of 2%. As a result of increase in wet aggregate stability and decrease in bulk density, air permeability increased, and penetration resistance decreased significantly. The results obtained in this study have clearly indicated that the vermicompost application is an effective way to improve soil physical characteristics.

“…Addition of organic amendments leads to an increase in soil water retention, root zone aeration and nutrient retention (Bigelow et al, 1999;Juncker and Madison, 1967;McCoy, 1992) but organic matter decomposition over time reduces hydraulic conductivity and air-filled porosity (Huang and Petrovic, 1995;McCoy, 1992). Inorganic amendments, retaining physical properties for extended period, are more appropriate (Aksakal et al, 2012;Truman et al, 2010). Among these zeolites, crystalline hydrated aluminosilicates having a three-dimensional crystal structures (Rehakova et al, 2004), have been recognized to improve the waterholding capacity (Huang and Petrovic, 1994;Xiubin and Zhanbin, 2001), the drainage control (Bigelow et al, 2004) and the retention and release of ammonium (NH 4 + ) due to their high cation exchange capacities (CECs) (Bish and Ming, 2001;Ferguson and Kissel, 1986;McGilloway et al, 2003).…”
