Zakat is due on agriculture upon the harvest of the crops and based on how water was provided for them. There are three possible Cultivation Zakat amounts that are due when the crops are harvested:
- All watering due to Rain or rivers: 10%
- Watering is all by your efforts (artificial): 5%
- Watering with a mix of above two options: 7.5%
You can pay your Zakat with the harvest itself, and scholars have also allowed for the monetary amount to be paid in its place.
