| Abstract | ||
| This study was conducted in the field of Agricultural collage . university of Basrah , karmat-All , during the spring season of 2012 on clay soil in order to study the effect of the distance of deep lines plowing on some properties of clay soil . two kinds of tillage used ; deep tillage, to shatter and breaking hardpan for the distances 1, 2 , 3 ,4 , and 5 m among plough lines , Forming treatment , (C1 , C2 , C3 , C4 , C5) and surface tillage by using moldboard plough . for all the treatments and control , only surface plough . this plough used orthogonal for two tillage , Factorial experiment choosed tillage and depth , six treatments , with three depths by using (RCBD) with three replicates. Results showed that the effect of the plowing depth on the values of accumulative Infiltration water (I) , Infiltration rate (i) and Electric Conductivity (EC) for two kinds of plough . which led to successive increasing of Infiltration water and Infiltration rate with depth which are reversible with tillage line distances for all the treatment , and C1 superiored on other tillage treatment. Allso an increase in values of infiltration water and infiltration rate to compared with the beginning of the control and high with values of C1 43.1 cm and 0.035 cm Sec-1 respectively and Highest low creasing in soil salinity of 7.938 dS m-1 . (I) and (i) was lowe with C0 ,but an increase in (EC) ) were in the depth 0 – 15 cm at the end of the experiment 13.587 dS m-1 as compared at the begining of experiment for the some depth. | ||
