How to use zinc sulphate heptahydrate in agriculture?
General
None Given
Hi there!
I would like to know how to use zinc sulphate.
I bought zinc sulphate heptahydrate and will spray it on my pecans.
I read values for zinc sulphate (36%).
I think that 36% means 36% of zinc, isn't it?
So this kind of zinc sulphate should be the zinc sulphate monohydrate.
The heptahydrate that I bought should have a 20% of zinc, so to have the same quantity I should use a little bit more.
To find how much of heptahydrate I should use I did this procedure : (monohydrate quantity *36):20= heptahydrate quantity.
Is it correct?
