Previous studies have focused on carbon (C) and nitrogen (N) stocks of soils because of increases in atmospheric carbon dioxide (CO 2 ) and terrestrial ecosystems with wide N storages. The goal of this study is to determine C amounts and stocks that are important for global warming, N amounts and stocks and C:N ratios. To this end, 16 series were opened on the Harran Plain and soil samples were taken from 100 cm depth and each horizon. The results showed that average carbon amounts changed between 3.61 and 6.47 kg C m . Carbon and N stocks were determined as 10.53 Tg C and 1.96 Tg N, respectively. Student's t-test was used on all data comparisons and equation determinations, and data were examined at p<0.05 and p<0.01 importance levels.
This field experiment examined the effects of magnesium (Mg) and phosphorus (P) fertilizers, which were given in different doses to soybean grown in different water levels, on plant water consumption, water-yield relations and grain yield factors. The experiment used a random blocks designed with three consecutive and was conducted over two years 2006 and 2007. Four different P doses (0-4-8-12 kg P da-1) and three different Mg doses (0-4-8 kg Mg da-1) were applied with three different water levels (I1, I2, I3). Cumulative pan values obtained from Class A Pan evaporation pool were applied as irrigation (I) 33% for I1, 67% for I2, 100% for I3. At the end of experiment were determined plant water consumption, water-yield relations and grain yield. At the start of irrigation, 548.00 mm, 786.00 mm and 1 017.00 mm of water were given to I1, I2 and I3 plots, respectively in the first year, and 457.98 mm, 698.02 mm and 931.00 mm irrigation water was given in the second year. Plant water consumption values (ETa) were determined as 648.00 mm, 903.00 mm and 1164.00 mm for I1, I2 and I3 parts in the first year, and 567.00 mm, 825.00 mm and 1070.00 mm in the second year. Moreover, according to experiment plots, irrigation water treatment efficiency (IWTE) varied between 0.14 and 0.53 kg m-3 in the first year and between 0.16 and 0.59 kg m-3 in the second year.
This study was conducted to determine the nutritional status of olive cultivated land and olive plant in Izmir and Mugla province in terms of boron and other elements. For this purpose, 254 soil samples (0-30 cm depth) and 254 leaf samples were taken simultaneously with GPS coordinates from the olive production areas and analyzed (125 gardens in Datca,
Bu çalışma, Muğla ilinde zeytin yetiştiriciliği yapılan toprakların ve zeytin bitkisinin bor ve makro elementler yönünden beslenme durumunun belirlenmesi amacıyla yürütülmüştür. Bu amaçla Muğla ili Datça, Köyceğiz, Milas, Ula, Seydikemer ilçelerinden toplam 125 bahçeden toprak ve yaprak örnekleri eş zamanlı olarak alınmıştır. Toprak örneklerinde; tekstür, pH, EC, kireç, organik madde, ekstrakte edilebilir P, K, Ca, Mg, Na; yaprak örneklerinde ise toplam P, K, Ca ve Mg analizleri yapılmıştır. Araştırma alanı topraklarının büyük çoğunluğu kumlu-tın ve killi-tın bünyeye sahiptir, organik madde içeriği düşüktür. Hafif alkalin, nötr ve orta asit özelliğine sahip topraklar tuzsuz sınıfında yer almıştır ve büyük çoğunluğu yüksek kireç içermektedir. Toprak ve yaprak analiz sonuçlarına göre; Araştırma alanı topraklarında B, P, K açısından ciddi beslenme sorunlarının yaşandığı tespit edilmiştir. Ca ve Mg bakımından da çok ciddi oranda olmasa da beslenme sorunlarının yaşandığı saptanmıştır. Ayrıca toprağın besin maddesi miktarları ile yapraktaki besin maddeleri arasında güvenilir düzeyde korelatif ilişkiler elde edilmiştir. Muğla ilinde gerçekleştirilen bu çalışmanın sonuçları dikkate alındığında, etkili gübreleme programı, yöntemi ve zamanının son derece önemli olduğu anlaşılmaktadır. Zeytin tarımında kaliteli ve yüksek verimli üretim; dengeli gübreleme, organik gübre ilavesi ve diğer teknik uygulamalarla ilgilidir.
