For example...

For example, it must be specified whether it is rice or wheat, and if it is rice, then the type of rice must be specified. However, if the parties do not have a particular crop in mind, it is not necessary for them to specify it. Similarly, if the crop they have in mind is known, it is not necessary to expressly state it; 7. the owner must specify the land if he has a number of pieces of land which are different in terms of their agricultural qualities.

However, if there is no difference between them, specifying the land is not necessary. Therefore, [in the latter case,] if the owner says to the farmer, ‘Farm one of these pieces of land’ and he does not specify which piece, the sharecropping is valid, and after the conclusion of the contract the owner can specify which piece of land [he would like the farmer to farm]; 8.

the expenses that each of them must pay for – such as the cost of the seeds, fertilisers, farming equipment, and suchlike – must be specified. However, if the expenses that each of them must pay for are such that they are usually known, it is not necessary to expressly state them.
