Can the overdue Zakat on crops for ten years be paid to clear one's liability?

Whoever harvested a crop from their land that is subject to zakat (definition), and it reached the nisab (definition) (approximately 653 kilograms), must repent to Allah and immediately pay the zakat for the past years. The amount of zakat is one-tenth if the land is irrigated without cost, and half of one-tenth if it is irrigated with cost. What was spent on the land for cultivation is not deducted according to the majority of scholars, but the more preponderant opinion is to deduct the expenses from the overall harvest, and the zakat is then on the net yield. One must hasten to pay the delayed zakat to clear their conscience.
