Evaluation of soil fertility in citrus planted areas by geostatistics analysis method
Abstract
The aim of this study is to map citrus planted
areas, which have been detected by traditional methods to date, with a high
accuracy method and to reveal the land characteristics and fertility
conditions. A database was created for citrus planted areas with the help of
high-resolution Worldview 2 satellite images in this study. By creating the
digital elevation model, orthorectification of satellite images was made and
slope, aspect and elevation characteristics were determined. Using soil maps,
maps showing terrain characteristics were produced. 43 soil samples were taken
to represent citrus planted areas; geostatistical maps showing their pH,
salinity, lime, texture, organic matter, total N, available P; exchangeable K,
Ca, Mg, Na, available Fe, Cu, Zn, Mn levels were created and their statistical
analyses were performed 2,132.08 ha citrus planted area was found in the study
area. The parameters obtained from the digital elevation model (slope, aspect,
elevation), the data of the land from the soil maps and the physical
properties-macro/micro nutritional contents of the soil produced by the
geostatistics method were evaluated together. It was determined that the
features in all areas mapped as citrus planted area are quite suitable for
citrus production. However, it is thought that Fe and Zn uptake from the soil
will decrease due to the fact that the pH level is slightly alkaline and high
lime contents. Identifying and sustainable monitoring of citrus production
areas, which are very important in terms of economy, accurately, up-to-date,
without causing loss of time and labor, will be possible with integrated use of
GIS and RS techniques.
