effect of soil compaction on some quantity and quality characters of sugar beet
soil compaction reduces growth of secondary roots, soil aeration and water and mineral uptake by plant, and decreases chlorophyll content as well as root yield and sugar content. hence, the effect of soil compaction on sugar beet yield and sugar content farms determined by penetrometer using 40 plots of 100 m2 in 40 sugar beet field of hamedan, asadabad, malayer and bahar at the depth of 0-80 c...
متن کاملNumerical simulation of dynamic soil compaction with vibratory compaction equipment
Roller drums make use of various shapes and their dynamic compaction effect is achieved by different kinds of dynamic excitation systems. The bearing capacity of layered soil constructions can be measured during the soil compaction process. The finite element method has been applied for dynamic analyses using elastic models. For the realistic simulation of the dynamic compaction process it is n...
متن کاملSoil Compaction: Effects and Amelioration
Soil compaction was identified as the cause of ‘growth stunting disease’ in sultana grapes and ‘red death’ in cotton at the Lower Orange River and Vaalharts irrigation schemes. In an experiment growth stunting disease was eradicated completely and yields of sultanas increased substantially by deep cultivation, which eliminated compacted soil layers. Ripping increased the quality of tobacco, and...
