“…These consistency limits can provide a means of describing the degree and kind of cohesion and adhesion between soil particles and any biochar amendments with respect to the resistance of the soil to deform or rupture. As the PI value of soil increases, the range of moisture over which the soil is susceptible to compaction by external forces increases (Aksakal et al, 2013). Amendment with 6% coal fly ash (PS < 2 mm) significantly (p<0.05) decreased the θ ll and increased the θ pl of clay soil and led to a decrease in soil PI of 35% .…”

A b s t r a c t. Biochar is proven to enhance soil fertility and increase crop productivity. Given that the influence of biochar on soil compaction remains unclear, selected physico-mechanical properties of soil amended with wood-derived biochar were assessed. For unamended silt loam, the bulk density, maximum bulk density, optimum moisture content, plastic limit, liquid limit, and plasticity index were 1.05 Mg m -3 , 1.69 Mg m -3 , 16.55, 17.1, 29.3, and 12.2%, respectively. The penetration resistance and shear strength of the unamended silt loam compacted in the standard compaction Proctor mold and at its optimum moisture content were 1800 kPa and 850 kPa, respectively. Results from amending the silt loam with 10% particle size ranges (0.5-212 µm) led to relative decreases of 18.1, 17.75, 66.66, and 97.4% in bulk density, maximum bulk density, penetration resistance, and shear strength, respectively; a 26.8% relative increase in optimum moisture content; along with absolute increases in plastic limit, liquid limit, and plasticity index of 5.3, 13.7, and 8.4%, respectively. While the biochar-amended silt loam soil was more susceptible to compaction, however, soil mechanical impedance enhanced.

“…While the observed parameters were positively and significantly correlated with clay content, they were negatively correlated with silt and sand contents (Table 3). Clay, sand, and organic matter contents, which influence the soil diffused double layer characteristics, have significant effects on the Atterberg limits (Lal and Shukla, 2004;Hemmat et al, 2010;Aksakal et al, 2013). De Jong et al (1990) stated that clay content is the most important determinant of the Atterberg limits.…”

“…Several studies showed that an increase in soil structural stability significantly decreases soil compatibility (Baumgart and Horn, 1991;Barzegar et al, 1996;Aksakal et al, 2013). Agricultural management practices that favor organic matter addition and/or accumulation are known to increase AS (Batjes, 2014;Yazdanpanah et al, 2016).…”

“…If tillage is not timed properly (wetter or lower than the OMC), it is expected to degrade the soil structure and require excessive energy to operate (Dexter and Bird, 2001;Keller et al, 2007). It is expected that an increase in the Atterberg limits and the Proctor OMC will not only minimize compactibility but will also cause a higher workable range and hence resistance to external mechanical forces (Aksakal et al, 2013).…”

“…Seed vigor can be defined as the ability of the seed to germinate and become established under less than optimal conditions, or to survive a series of environmental stresses during germination (Balla et al, 2012). Diatomite (DE) is a sedimentary rock primarily composed of the fossilized remnants of unicellular fresh water plants known as Diatoms (Danil de Namor et al, 2012;Aksakal et al, 2013). It is mainly comprised of SiO 2 with small concentration of Fe 2 O 3 , Al 2 O 3 , MgO, CaO and organic matters (Wang et al, 2012).…”

In order to evaluate the effects of different materials on germination and growth of tomato (Solanum lycopersicum L.) cultivars under negative pressure hydraulic auto-irrigation systems, an experiment was conducted in National Engineering Research Center for Intelligent Agricultural Equipments, Beijing, China. Three cultivars of tomato as main plots, and three materials, including: 100% soil, 50% diatomite + 50% soil, and 100% diatomite as sub plots, were evaluated in a split plot based on randomized complete block design with three replications in a green house. Cultivar effect was significant on total germination percentage, speed of germination, radicle length, coleoptiles length, fresh leaf weight and fresh coleoptiles weight were significance. The influence of material on total germination percentage, speed of germination, mean germination time, coefficient of velocity germination, radicle length, coleoptiles length and fresh leaf weight were meaningful. The highest total germination percentage (74.99%), coefficient of velocity germination (0.57), coleoptile length (6.00 cm), fresh leaf weight (0.31 g), fresh coleoptile weight (0.30 g), dry leaf weight (0.019 g) and dry coleoptile weight (0.017 g) was observed in Jiafen No-18. However, Jiahong No. 4 had the maximum speed of germination. While maximum values of total germination percentage, speed of germination, mean germination time was related to 100% soil. Application of 50% soil + 50% diatomite obtained the highest radicle length, coleoptile length, fresh leaf weight, fresh coleoptile length and dry leaf weight. It seems that application of 50% soil + 50% diatomite, and Jiafen No. 18 is appropriate under the negative pressure hydraulic auto-irrigation system.
