Effect of organic fertilizers on soil chemical properties on vineyard calcareous soil
The aim of investigation was to determine effect of different organic fertilization on soil chemical properties on vineyard calcareous soil. Three year fertilization trial was carried out from 2008 to 2010 in the Plešivica wine-growing region, in north-western Croatia, in a 10-year old vineyard, cv. Sauvignon White grafted on Kobber 5BB rootstock, planted on soil with quite high pH for grapevine growing (pHKCl 7.15), containing 2 mg P2O5 100 g-1 soil, 14 mg K2O 100 g-1 soil and 13.5 % CaO. The trial was performed according to randomize complete block design with 6 treatments (unfertilized, farmyard manure 20 t ha-1 and 40 t ha-1, peat 20 000 L ha-1 and 40 000 L ha-1, NPK (5-20-30) 500 kg ha-1+2x100 kg UREA kg ha-1) in 4 repetitions. Average soil samples from two depths (0-30 cm and 30-60 cm, respectively) were taken at the end of each growing season (October). The monitored soil chemical properties were: soil pH, organic matter, total nitrogen content, available phosphorus (P), available potassium (K), CaCO3 content and CaO content. Statistically significant differences in soil reaction (pH) in plowing layer (0-30 cm) were found among fertilization treatments in the first and third year of studies. In the plowing layer (0-30 cm) in all three years of the study significant differences between the average total nitrogen content, and available P as well were found, while there were no significant differences in the subplowing layer (30-60 cm). Due to average value of fertilization treatment, statistically significant difference in the amount of available K in plowing layer were found in the first and second year, while in subplowing layer statistical differences were found in the first and third year of investigation. Therefore, fertilizing with different organic fertilizers significantly influenced the most of studied chemical properties of the soil, especially in plowing layer (0-30 cm).
