Measuring fertilizer components for solutions

I found an inexpensive electronic balance (scale) that
can be used for measuring the K2SO4, KCl, KNO3, etc
for making fertilizer solutions.  It is a Sunbeam
Digital Electronic Postal Scale at OfficeMax
(www.officemax) for $29.99 (item#20073778).  I tested
its accurancy against the balances in my lab and the
inaccurancy seems to be +/- 1 gram, not too bad for
such a cheap scale.  This level of inaccuracy should
not appreciably affect the composition of fertilizer
stock solutions.
