A long-term fertilizer experiment on maize-wheat cropping system was initiated in 1972–
1973 on a Typic Hapludalf at Research Farm of Palampur which comprised of ten treatments
up to 1980–1981. The eleventh treatment, consisting of 100% NPK (− S) was introduced in
kharif 1981. After twenty-six years of continuous cropping (kharif 1981 to rabi 2007–2008),
the effect of different chemical fertilizers and amendments with or without sulphur (S)
application was studied on different forms of S. Continuous application of chemical fertilizers …
