Sir,it is very difficult to find who is earning 20 L and who is earning 2 L.farmer will not show the income.I think some farmer earning 20 lakh in 2 acre and one is earning 5 lakh in 10 acre.Govt will not able to find that. how one should justify tax even if taxed on holding of land.I thing before taxing farmers permit them to fix there own price,let market decide.Start Futures contrat of 3 years in commodities like in US .Dont stop farmers from selling its crop in any state(major problem).2 years back when paddy was on peak UP farmer can not sell in Haryana when the price is high there.There are lot of restictions in selling crop from one state to another.I have 14 acre of land but I am not able to earn more than 8 lakhs.These bloddy suagr mills not paying.
