Impact of fertilisers on soil properties and biomass yield under a long-term sweet sorghum cropping system

A continuous long-term field experiment (2008–2018) was conducted in Xinjiang, north-western China, to assess the impact of farmyard manure (FYM) and inorganic fertilisers on sustainable biomass yield sweet sorghum cultivar (Xingaoliang No. 3) soil chemical properties. Seven treatments, associated with nitrogen (N), phosphorus (P), potassium (K), FYM, their different combination, were compared control plot (CK). As a result, treatments NP, PK, NK, NPK NPKM significantly increased average yields by 30–48% over CK. The 12 t/ha FYM per year (NPKM) both total soluble solids (TSS) 48% 7.9%, respectively, while 18 t/ha/year application rate had an adverse effect yield. Stem TSS, available N K for all decreased organic carbon, salt P applied years. pH stabilised at 7.8–8.2 end. In conclusion, is most efficient single or incorporation fertilisers. more reasonable fertiliser increase irrigation reduce needs further investigation.
