We have a similar law in US. There are easements and hostile possession. Honestly, it is meant to benefit those that are combating hostile landowners and landlords. In US, the owner of the property has to be responsible for it and take care of it. You have to ask yourself if the land was so important, why did the owner allow crops to be planted? Even after they were planted, why did the landowner allow them to stay until they matured? This process takes days or even weeks. What was the landowner doing in this time? In US, if a landowner knowingly allows someone to do as they please with the land for a period of time, the land becomes the property of the person taking care of it. Basically, if you're not willing to take care of the land, it goes to someone that will.
