It's difficult to see any benefit to the landlowner if he has no interest in the crop. On share rented ground I split the cost with the landowner with it prorated over 5 years should I not retain the lease.
I assume you could invest in the lime if you have along term lease or a guarantee that future tenants would reimburse you for the unused portion of the lime. Assuming a five year life of the lime, the new tenant would assume responsibiity for the unused portion.
In a cash rent lease, the investment in lime would be a capital investment for the landlord just like drainage tile and he would not have the ability to deduct the investment.
