Dear querist: you have not understood the provisions of the referred law under which your husband has been served with notice by the Karnataka State Revenue department. The sections 79a and b is clear about acquisition of land by an individual or joint family whose income is not less than Rs. 2 lakhs by other than agricultural lands.
The following information is furnished which may be useful for understanding the problem:
Agricultural land can be bought in Karnataka after fulfilling certain requirements.
The annual average income of the person including agricultural income should be less than Rs 2 lakhs.
The person must have had an agricultural land in his name before the year 1974. The person should be an agriculturist or an agricultural worker by profession.
As per Section 79A of the Karnataka Land Reforms Act 1961, the non-agricultural income of a purchaser who must be an agriculturist should not exceed Rs 2 lakhs per year.
To purchase agricultural lands, these documents need to be produced:
Form No 1: Vendor's Pani, mutation Purchaser's pani;
No objection certificate from the Tahsildar
Government permission in specified cases (like purchase of agricultural lands by people other than agriculturists and agricultural workers)
RTC, i.e., record of right, tenancy and inspection of crops. This is a primary record issued by the village accountant. It contains the details of survey number, total extent of the land, names of the owners and their extent of holding, persons in possession, details of crops grown, and land revenue for any particular period. It also contains the details of conversion of land from agricultural to non-agriculturalal

Section 79 A&B endorsements:
These are issued by the Tahsildar. These endorsements certify that there are no cases against the person owning the agricultural land, and whether he is an agriculturist or not, conforming to the prescripttions of Section 79 A&B of the Karnataka Land Reforms Act 1961 (since only agriculturists and agricultural workers whose average annual income is less than Rs 2 lakhs are entitled to own agricultural lands in Karnataka);
Form No 7 endorsement:
This is also issued by the Tahsildar. This endorsement certifies that there are no tenancy cases pending in respect of the property in question, as per the Karnataka Land Reforms Act 1961.
The Saguvali Chit is also called the certificate of grant. This is issued on Form No VII in case of grant of government land to eligible persons for cultivation. This establishes the title of the person named in the Saguvali Chit to the land granted. A sketch of the land granted will be annexed to the Saguvali Chit. The grant of the land is subject to the conditions detailed in the Saguvali Chit.
This is a record given to a holder of agricultural land and includes tenants if he is primarily liable to pay land revenue. It contains a copy of the record of rights to the land.
