So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

İzmir İli Tarım Topraklarının Verimlilik Durumları ile Mikroelement Kapsamlarının Belirlenmesi Haritalanması
2021

Abstract:

Araştırma, İzmir ili tarım topraklarının verimlilik ve mikroelement kapsamlarını belirlemek, CBS tekniği  kullanılarak veri tabanı ve dağılım haritalarını oluşturmak amacıyla 2014-2017 yıllarında yürütülmüştür.  Araştırma kapsamında, tarım alanlarını temsil edecek şekilde 2.5 km x 2.5 km aralıklarla 0-20 cm toprak  derinliğinden 502 toprak örneği alınmıştır. Alınan toprak örneklerinde bünye, pH, EC, kireç, organik  madde ile ekstrakte edilebilir fosfor, potasyum, demir, bakır, çinko ve mangan analizleri yapılmıştır.  Toprak analiz sonuçları, belli kriterlere göre sınıflandırılarak, besin maddelerinin eksiklik, yeterlilik veya  fazlalık seviyeleri belirlenmiştir. Araştırma sonucuna göre, İzmir ili tarım  topraklarının %55.18’inin kumlu  tın-kumlu killi tın bünyede, %49.60’ının orta alkali, %42.03’ünün çok hafif tuzlu, %57.17’sinin kireçsizçok  az kireçli, %55.98’inin ise çok az organik maddeye sahip olduğu saptanmıştır. Alınabilir elementler  bakımından %28.09’unda fosfor yetersiz, ekstrakte edilebilir elementler bakımından %47.21’sinde  potasyum zengin, %90.84’ünde demir, %96.61’inde mangan yüksek, %44.42’sinde çinko, %69.92’sinde  bakır orta seviyede bulunmuştur. Toprak parametrelerinin sınıflandırılmasından sonra CBS kapsamında  veri tabanı oluşturulmuş ve IDW yöntemi kullanılarak toprak dağılım haritaları üretilmiştir.

Determining and Mapping The Fertility and Microelement Scopes Of The Agricultural Soils Of İzmir Province

Abstract:

This research was carried out to determine the fertility and microelement scopes of the agricultural  soils of İzmir province and to create a database and distribution maps (pin maps) by using geographic  information systems technique between 2014-2017. Within the scope of the research, a total of  502 soil samples, representing agricultural areas, were taken from 0-20 cm soil depth with 2.5 km  x 2.5 km grid intervals. In soil samples taken; texture, pH, EC, lime, organic matter and extractable  phosphorus, potassium, iron, copper, zinc and manganese analyzes were performed. Soil analysis  results were classified according to certain criteria and deficiency, adequacy or excess levels of  nutrients  were determined. After the classification of soil parameters, a database was created within the scope  of GIS and soil distribution maps were produced via Inverse Distance Weighted method. According  to the results it was found out that, 55.18% agricultural soils of İzmir was sandy-loamy, 49.60% was  mildly alkaline, 42.03% was slightly saline, 57.17% was non calcareous-slightly calcareous, 55.98% had  minimal organic matter. In terms of available elements, 28.09% did not have enough phosphorus, in  terms of extractable elements 47.21% had high potassium, 90.84% had high levels of iron, 96.61%  had high levels of manganese, 44.42% had zinc and 69.91% had medium levels of cooper.
