Prepping land for secondary crops

Recovering from the draught has been a slow process, and the setbacks have been plenty, but I guess if farming in Sub-Saharan Africa was easy, everyone would be doing it. This is definitely a job of passion... Right now we are prepping a section of the farm which has hardened and compacted over 25 years of grazing animals and stagnant status, returning it close to virgin soil. so far the majority has been cut down and cleared but ripping the soil seems to be posing a problem, we will need some help from some bigger machinery for this job, and hopefully we will manage to get a bulldozer in for the job soon.
