Is zakat due for past and future years on agricultural land purchased with the intention of investment and sale when needed, and what is the zakat on pear fruit that has not yet borne fruit?

Zakat (definition) is obligatory on land if it was intended for trade at the time of purchase. Its value is one-quarter of one-tenth annually, and the zakat for past years, if due, must be paid. However, if it was not intended for trade at the time of purchase, or if there was hesitation regarding the intention, then, according to the majority of scholars, no zakat is due on it. If the land was purchased with the intention of both trade and gaining produce (ghallah), then zakat is obligatory on it. As for pears, there is no zakat on them according to the majority of scholars, but Abu Hanifa obligates zakat on them if they reach the nisab (definition), which is 653 kilograms.
