What is the amount of zakat due on an orange grove that was sold for 31 million Algerian Dinars, according to the Maliki school of thought?

If the mentioned field is not money acquired for trade, then there is no zakat on it. This is because the preponderant opinion among the majority of scholars is that fruits, citrus, and vegetables are not subject to zakat. Similarly, zakat is not obligatory on their price until a full year has passed over it, provided it reaches the nisab (threshold) by itself or when combined with other money and trade goods. The nisab for currencies is the equivalent value of eighty-five grams of gold or five hundred ninety-five grams of silver, and the amount due for payment is a quarter of a tenth, or 2.5%.
