The effects of pruning waste of citrus (Citrus sinensis) applications on the some productivity parameter changes of the soil

The purpose of this experiment was to determine the effect of orange (Citrus cinensis var. "Washington Navel") pruning waste (OPW) applications with two soil tillage equipment (disk harrow and freeze) on changes in some productivity parameters of soil. OPW applied for two years after the power take off (PTO) driven pruning residue chopper. At the end of the application, effects of OPW on soil properties were determined in soil samples obtained from 0–10 and 10–20 cm soil depth. In the experiment, OPW applications to soil based on dry matter as 306.0 kg da-1 every two years after the pruning is done. In the study, especially in the second year of the experiment, organic matter (OM), cation exchange capacity (KDK), total nitrogen (N), phosphorus (P), calcium (Ca+2), potassium (K+), copper (Cu+2) and electrical conductivity (EC) values have increased significantly in both depths of the soil. On the other hand, it was determined that the value of bulk density (HA), soil reaction (pH), amount of changeable sodium (Na+), iron (Fe+3) and manganese (Mn+2) decreased with the applications. OPW applications showed a significant increase in the amount of available water (AW) in the second year of the experiment, but did not make a significant difference between the periods. Considering the results obtained in this project; the use of OPW on a regular basis will benefit in terms of soil productivity and environment
