Conservation agriculture has been developed as a means to improve the sustainability of agricultural systems and reduce drawbacks conventional practices. Cropping practices can have large influence on soil properties such water retention. Proper tools are needed assess model effects conservation properties. As measuring retention is expensive time consuming, pedotransfer functions (PTFs) now co...

Recent studies have shown that soil particle size analyses using laser diffraction method (LDM) can give compatible results compared with traditional sedimentation based methods, if the clay-silt cutoff is transformed. Additionally, procedures including separation of sand fraction by wet sieving and running a well dispersed sample only fractions smaller than during measurement, given promising ...
