dc.description.abstractThe aim of this study was, firstly, to determine the soil fertility potential, secondly, to summarize an inventory of agromineral resources using an agrogeological approach in Biga Peninsula. Soil texture, soil reaction, electrical conductivity, soil organic matter, CaCO3%, total nitrogen, available phosphorus, exchangeable potassium analysis were conducted on 1877 soil samples. The results were mapped and interpreted in conjunction with the geological map for agrogeological evaluation. The approach was validated with spatial autocorrelation analysis. pH values ranged from 4 to 5 in 0.69% of the study area, whereas those pH > 8 were found in 3.89%. Depending on the soil requirements of the land use type, material transfer from locations rich in lime to areas with low pH is recommended. While some areas exhibit high nutrient element contents, others, despite being under similar land use, show nutrient deficiencies due to parent material. Phosphorus levels were found to be very low in 0.32% of the total area, whereas approximately 37% exhibited high to very high phosphorus content. Similarly, potassium levels were very low in 4.95%, while 12.5% of the area showed high to very high potassium levels. Moran's I values for CaCO3, phosphorus, and potassium were 0.603, 0.300, 0.447, respectively, indicating spatial autocorrelation. This study identified potential zones in Biga Peninsula, where particularly potassium and phosphorus-rich materials could be transferred from high areas to areas of deficiency. The applications should be utilized on organic farmland, smallholder farms, land requiring rehabilitation, degraded areas, and pastureland, rather than on large areas.
