Temporal effects of organic and conventional farming systems on the chemical properties of vineyard

Summary

In this study, It is aim to compare the effects of chemical properties in organic and conventional vineyard farming system for 9 year long between 2000-2009.in Manisa,Salihli, in Aegean Region. The study was carried out in 5 replicates completely randomized design According to soil analysis results, certified fertilizer and green manure and ground pruned branches were applied as plant nutrition material in organic plots. On the other hand, 21% ammonium sulphate, 26% ammonium nitrate, 43% triple super phosphate as P2O5 and 48-52% potassium sulphate as K2O were applied in conventional plots. According to soil analysis results, there were no changes in saturation, salinity and lime values in both farming system. In conventional plots, phosphorus level increased whereas pH level decreaed, suggesting that organic management practices may improve soil properties and sustainability.
