secondary tillage implements , disc harrow , bulk density .Abstract
The search was carried out in spring (2024) in one of the fields of Tartous with clay loam soil where the ground is previously plowed using chisel plow in order to study of effect of of secondary tillage implements, which are disc harrows and rigid teeth harrows on some soil physical properties which are bulk density, total porosity and size distribution of clods .
The results showed that disc harrow gave the high value of bulk density (1.73 g/cm3) and it gave the value of total porosity ( 31.4 %), while rigid teeth harrows gave value of bulk density (1.72 g/cm3) and it gave the value of total porosity ( 29.4 %).
As for the size distribution of clods , aggregate stability of diameters (1-5mm) increased by 36%, 26% using disc harrows and rigid teeth harrows respectively.
