  1. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Mineral fertilization and liming impact on maize and wheat yield Zdenko LONČARIĆ, Domagoj RASTIJA, Krunoslav KARALIĆ, Brigita POPOVIĆ Faculty of Africulture in Osijek, Croatia

  2. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia • The aim of paper: • Combined influence of liming and phosphorus mineral fertilization on: • soil pH reaction • wheat and maize yield • phosphorus & calcium concentrations & removal

  3. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Field trials at Donji Miholjac (eastern Croatia) liming 2003 – maize 2004 – wheat 2005 Soil properties dystric luvisol calcaric regosol pHKCl 4.02 7.14 humus 1.66 % 1.42 % P2O5 149 mg kg-1 139 mgkg-1 K2O 167 mg kg-1 109 mg kg-1 calcaric regosol: limey substrate excavated & redeposited as top soil layer back in 1986

  6. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Liming & P fertilization impact on maize yield:

  7. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Liming & P fertilization impact on wheat yield:

  8. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Wheat: P & Ca removal in kg ha-1 kg P ha-1 kg Ca ha-1

  9. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Maize: P & Ca removal in kg ha-1 kg P ha-1 kg Ca ha-1

  10. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Conclusions • Increasing mineral phosphorus fertilization decreased soil pH • Liming increased wheat grain yield and P removal • Doubled P fertilization didn’t significantly influenced yield • Grains removed more P & less Ca than straws

  11. 5th Alps-Adria Workshop, 6th-9th March 2006, Opatija, Croatia Liming & P fertilization impacts to publish... • Liming:Al, Co, Mn, Ni, Pb Ca, P, B, Mo SOIL 2. P fertilization: P, Cd WHEAT GRAIN • Liming:Co, Cd, Fe, Mn, Ni B, Mo 2. P fertilization:Zn Cd
