Tips for sulphur management in crops

 The sulfur requirement of crop varies from is 5 to 50 kg / ha depending upn crop type and
the amount of sulphur available in the soil. Therefore, apply sulphur according to the
requirement of crop.
 Normally the requirement of sulphur is higher in oilseed crops than pulse crops.
According to an estimate, one tonne of cereals, pulses and oilseeds crops require 4, 8 and
12 kg sulphur respectively. This is the reason that oil seed crops are most responsive to
sulphur application.
 As per availability, any source of sulphur source given in Table 1 can be used. However,
single super phosphate, gypsum, phospho-gypsum, pyrite, bentonite-sulphur are more
useful for sulphur nutrition.
 Generally, the use of sulphur has been found to be the best in the form of fertilizer in
crops, but it can also be used at 25-30 days after sowing during weeding.
 It should be remembered that in the condition of adequate soil moisture, sulphur fertilizers
should be broadcasted on the soil surface.
 With the use of proper quantity of organic manures, sulphur deficiency can be overcome.
But high yielding crops require additional amount of sulphur, which can be fulfilled by
addition of fertilizers.
