What is the zakat amount for a plot of land purchased for investment, and is it due every year?

Zakat is obligatory on land that you have acquired with the intention of trade. Its value is calculated at the end of the Hijri year, and zakat is paid on this value if it reaches the nisab or completes the nisab by combining it with other assets. It is obligatory to pay 2.5% of its total value every Hijri year, as long as the land is owned with the intention of trade.
