Abstract
Soil properties of the samples from orchards and the nutrients (macro- and microelements) in the clementine mandarin (Citrus reticulata Blanco), widely grown in the Köyceğiz region of Muğla Province Turkey, were studied. Mandarin tree leaves and soil samples were collected from 10 different orchards. The soil samples were analyzed for its pH, CaCO3, EC, sand, organic matter, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) and boron (B) while leaves were analyzed for its macro- and microelements. The results obtained from soil analysis showed suitable amount of calcium carbonate and EC. Analysis of the soil showed that organic matter, N, K and Mn were insufficient in all orchards, while Fe was higher in amount. Slight alkaline, strong alkaline and neutral pHs were determined in the orchards. Besides, the leaf samples collected from the orchards reflected deficient amount of N and Ca while higher amount of Mg and Fe.
Highlights
Plants need to be balanced with the necessary nutrients for their growth and increase in yield
This study aims to determine the mineral nutritional status and soil properties of Clementine mandarin (Citrus reticulata Blanco) cultivated in Koycegiz, Muğla
Plant analysis is complementary to soil analysis. It does not indicate the amount of nutrients present in the soil, but how much the plant can benefit from the nutrients in the soil
Summary
Plants need to be balanced with the necessary nutrients for their growth and increase in yield. The effects of fertilizers, applied to especially perennial plants such as fruit trees, on yield and quality have been proved by many studies. Since fruit trees are perennial plants, compared to single-year plants, it is much more important to determine the correct amount of nutrients to be applied for their fertilization and to confirm the effects of fertilization on product quantity and quality [2]. Citrus trees are comprised of a group of plants including citrus fruit tree species with high economic value such as orange (Citrus sinensis), mandarin orange (Citrus reticulata), lemon (Citrus lemon), grapefruit (Citrus paradisi), bitter orange (Citrus aurantium) and bergamot (Citrus bergamia). 52.63% of the world citrus production is orange, 21.13% is mandarin, 11.19% is lemon, 6.22% is grapefruit and the rest is other citrus fruits [3] Citrus fruits are the most produced fruit species in the world with a production of approximately 136 million tons. 52.63% of the world citrus production is orange, 21.13% is mandarin, 11.19% is lemon, 6.22% is grapefruit and the rest is other citrus fruits [3]
