The objective of this studywas to evaluate important management practices as they relate tochanges in bulk density of a tilled sandy loam soil. Practices evaluatedwere irrigation method, time between tillage and traffic, tire pressureand wheel load of applied traffic, and controlled traffic. ...
New experimental data and results from published studies are gathered into two databases to explore the effects of particle shape on packing density and on the small-to-large strain mechanical properties of sandy soils. In agreement with previous studies, these data confirm that increased angularity ...

Based on the research of normalization of SPT -n, a method to estimate the relative density of normally consolidated sandy soils is proposed. 在介绍标准贯入N值归一化研究成果的基础上,提出了用归一化标准贯入N值估算正常固结砂土相对密度的方法。 5. Spore density was also significantly correlated with ...
The experiment had been conducted from August to November 2016 at Samas sandy soil coastal area. The research aimed to determine growth response of mung bean sheltered by various density of sweet corn on coastal sandy soil. The experiment used the nested design with two factors with three repli...
