Ah, I have seen khaira in my fields too, it is those yellow patches on young leaves. For our alkaline soils here, yes, zinc sulphate is the prescribed remedy. But I must say, merely broadcasting it is not enough—one must mix it well with farmyard manure to help the roots truly take it up. In my experience, the soil here holds its own stubbornness, much like an old man learning to use a smartphone.
