Hi
If I can add my :2cents: ... The one downside of a mould-board plough I can readily think of is this - the very action of its operation:
If your topsoil is not deep enough, a mouldboard will lift some sub-soil, which has comparatively poor nutrient value and leave it on top of, or mixed with, your highly-nutritious topsoil or garden soil. This will notably reduce crop growth.
Farming practices of years gone by were similar to this - using such a plough (mould-board or deep-disc) in winter or early spring, leaving a few weeks, then planting a fodder crop for livestock. After several years, the land was almost useless - a perfect example is our block, as well as all our neighbours - all ex-farmland with zero goodness left, water-repellent, very, very hard when it's dry and struggles to grow any grass at all in places! :ashamed:
I would suggest to criss-cross it with a single-leg deep-ripper first, this will loosen it without mixing it up, letting air and water deep into it. Then, if necessary, same with a chisel plough (5 or 7 tyne), depends on the soil type and condition. I would certainly then use off-set discs as Jeff describes above. In subsequent years you may not need to deep-rip, and maybe chisel-plough and disc just once each ... rely on your judgement. :thumbsup:
My father lived on the land all his life and was a very astute and successful farmer. That was how we prepared many, many paddocks for planting - we were dairy farmers. He also understood the importance of regular use of fertiliser - although we rarely used lime - we apparrently didn't have a soil ph problem, we frequently spread superphosphate (to add phosphate) and nitram (for nitrogen-enrichment). I would love to know how many
hundred tons of this I have spread whilst growing up - almost all of it with the MF135 we now have here! However he would not ever use a roto-tiller (we know them over here as a rotary-hoe). We never, ever owned one. I don't know why, but I guess he knew more about agriculture than I'll ever know!:laughing:
Hope this helps somehow; and may all your fruit and veggies grow high & huge!
