conventional tillage producers did not use Roundup as extensively prior to seeding. Conventional tillage usually consists of primary tillage, or plowing, and secondary tillage, Conventional tillage, such as moldboard plowing, leaves the soil surface bare and loosens soil particles, making them susceptible to the erosive forces of wind and water. Conservation tillage practices reduce erosion by protecting the soil surface and allowing water to infiltrate instead of running off. Mould board plough, disc plough, soil stirring plough, ridger plough, tool frames/carriers with mouldboard plough or tillage sweeps, etc.
Zero tillage not only reduce the cost of cultivation it also reduces the soil erosion, crop duration and irrigation requirement and weed effect which is better than tillage. Zero Tillage (ZT) also called No Tillage or Nil Tillage. The zero machine or zero tillage machine makes it quite effective and also reduces the tillage cost for a farmer.
They both have advantages & disadvantages,
Zero tillage (no-till) not only reduce the cost of cultivation it also reduces the soil erosion, crop duration and irrigation requirement, but there is a risk of carrying over plant diseases when crop residue is not incorporated into the soil after harvest.
Advantages of traditional farming include improved soil fertility, carbon sequestration, and biodiversity maintenance & disadvantages include negative implications of slash-and-burn activities in shifting agriculture.
Zero tillage has the following advantages:
1) Cost reduction due to not using machines
2) Reduction of wind and water erosion
3) Not disturbing the structure of the soil
4) Reduce water consumption
5) Preventing the germination of some weed seeds
6) Timely planting of crops due to the lack of a lot of tillage
7) Helping the growth and development of soil microbial population, especially earthworms

We have tried all of the above in several places over several years and have received an amazing response
تعتبر الزراعة بدون حراثة من انظمة الزراعة ذات الجدوى الاقتصادية العالية حيث تقلل من استهلاك الوقود باختزال مراحل الزراعة الثلاث ( الحراثة، التنعيم والبذار) إلى مرحلة واحدة وهي عملية الحراثة فقط وبذلك تقليل الصرفيات إلى الثلث. فضلاً عن تقليل الإجهاد الحاصل على التربة من خلال تقليل عدد المرورات في الحقل إلى مرور واحد فقط والذي يقلل من كبس التربة بالإضافة إلى عملية حصاد المياه كون مياه الأمطار تصل إلى الشق الذي يحدثه الفجاج بشكل كامل وعدم ضياع كميات كبيرة من المياه داخل التربة المحروثة. وكذلك الابقاء على بقايا المحصول السابق يحافظ على رطوبة التربة وعدم تعرضها إلى أشعة الشمس المباشرة و يقلل نظام الزراعة بدون حراثة من نمو الادغال بسبب عدم قلب التربة وبقاء بذور الادغال مدفونة في التربة.
