Bu çalışma, Atatürk Üniversitesi Çiftliği topraklarının verimlilik potansiyellerini belirlemek ve temel bitki besin elementlerine ait dağılım haritalarını hazırlayarak gübre uygulamaları ve araştırma çalışmaları için kaynak oluşturmak amacıyla yürütülmüştür. Çiftlik toprakları, genel olarak bitkiye yarayışlı N ve elverişli P bakımından yetersiz, buna karşılık değişebilir K bakımından son derece zengindir. İnceleme alanı topraklarının verimlilik seviyelerinin artırılması için, toprağın N ve P kaynaklı çiftlik ve/veya ticari gübrelerle takviye edilmesinin gerekli olduğu ve gübre uygulamasının belirlenen dağılım haritaları dikkate alınarak yapılmasının uygun olacağı değerlendirilmektedir.   EVALUATING FERTILITY STATUS  OF  THE ATATÜRK UNIVERSITY FARM SOILS  I: MACRO ELEMENTS (N, P, K)   SUMMARY: This study was undertaken to determine fertility potential of  the Atatürk University Farm soils and to map the spatial distribution patterns of plant nutrients. Results indicated that the amounts of total N and available P in soil were not sufficient for optimum plant growth , but the soil was  rich in exchangable K.  It was suggested that the N and P sourced fertilizers should be added to soil to increase its pruductivity by considering the developed maps showing the distribution patterns of  N, P and K within the research area.
