Treatments were including: A) reduced tillage, B) wheat and corn direct seeding, C) corn direct seeding for four years, wheat direct seeding for the first two years and the fourth year, and conventional planting in the third year, D) wheat direct seeding for four years, corn direct seeding for the first two years and the fourth year, and conventional planting in the third year, and E) conventional tillage. Results showed that conservation tillage methods increased soil moisture retention (at most 25%) with respect to the conventional tillage but, they did not increase soil organic carbon. Conservation tillage methods especially direct seeding increased soil bulk density (at most 13%), and decreased soil accumulative filtration and infiltration rate (at most 25%). Meanwhile, tillage methods had no significant effect on corn yield for three growing seasons. %U https://ijbse.ut.ac.ir/article_65630_f22e4f24e075862b5d10978fd9e38047.pdf
