Şanlıurfa Yöresi Zeytinliklerinin Beslenme Durumunun Belirlenmesi

Abstract

ÖzBu araştırma, Şanlıurfa merkez ve ilçelerinde bulunan bazı zeytin bahçelerinin genel beslenme durumlarını tespit etmek amacıyla 2010-2011 yılları arasında yürütülmüştür. Bu amaçla; yöreyi temsilen Şanlıurfa merkez ve ilçelerde bulunan zeytin bahçelerinin 17 tanesinden yaprak örnekleri ile 0-20 ve 20-40 cm derinliklerden toprak örnekleri alınıp, analiz edilmişlerdir. Elde edilen bulgulara göre toprakların genel olarak çok kireçli, hafif alkalin yapıda, tuzsuz ve organik madde miktarının yetersiz olduğu tespit edilmiştir. Yaprak ve toprak örneklerinde yapılan makro ve mikro besin element analiz sonuçlarından elde edilen bulgular neticesinde bölgede bulunan zeytinliklerin genelinde besin element noksanlıklarının olduğu ve bahçelerin neredeyse tamamında P, Zn ve B içeriklerinin yetersiz seviyelerde olduğu belirlenmiştir.

For this aim soil samples which were taken from different levels as, 0-20, 20-40, and leaf samples were collected and analyzed. According to obtained results; soils have a higher content of lime, slight alkaline, without any salinity problem and total organic matter is not sufficient. Macro and micro nutrient analysis made of soil and leaf samples and results showed that, olive orchards which are based in our region have not enough nutrition and it was determined that P, Zn and B contents are insufficient levels in nearly all of the gardens.

Boron content of large soil groups of Siverek (Şanlıurfa) region

“…According to the limit values reported by Richards 1954, the total salt content of the soil samples was determined as salt-free (Table 2). In the same region, the general nutrition status of some olive orchards located in the center and districts of Şanlıurfa was investigated by Söylemez et al (2017) who also reported that all of the % salt contents of soils were in the salt-free class.…”

“…Wolf (1971) in terms of boron boundary values in the soil compared to the province of Şanlıurfa Siverek district in terms of boron content of wide soil groups at a depth of 0-20 cm 65.78% very little (<0.4 mg / kg), 26.32% less (0.5-0.9 mg / kg, 7.90% was sufficient (1.0-2.4), at 20-40 cm depth, 81.58% was found to be very small, 15.79% was low and 2.63% was sufficient (Table 2). The aim of the study was to determine the general nutritional status of some olive orchards in the center and districts of Şanlıurfa in the same region Söylemez et al (2017) reported similar results.…”

“…The aim of the study was to determine the general nutritional status of some olive orchards in the center and districts of Şanlıurfa in the same region. Söylemez et al (2017) The organic matter contents of the lands of Şanlıurfa have been reported to be between 0.37% and 2.32% and, 88.24% of the soils have low organic matter content. The lowest boron concentration was 0.01 mg/kg and the highest boron concentration was 1.99 mg/kg.…”

In the same region, the general nutrition status of some olive orchards located in the center and districts of Şanlıurfa was investigated by Söylemez et al (2017) who also reported that all of the % salt contents of soils were in the salt-free class. The clay, sand and silt quantities of the soil of the major soil groups in Siverek district were at least 24.32%, 2.40% and 6.00% respectively, while the highest clay, sand and silt contents were 67.76%, 62.96% and 68.72%, respectively.…”
