Effects of Nitrogen and Phosphorus Fertilization on Micro Nutrient Contents of Trifolium angustifolium and Lotus suaveolens from Fabaceae on a Grassland Ecosystem: the Case of Kahramanmaras, Eastern Mediterranean Region of Turkey
Özet
This study examined the effectiveness of various grass plants as
Trifolium angustifolium and Lotus suaveolens from Fabaceae to fertilizer
treatments (N+P fertilization) to encourage the micro nutrition of this
vegetation. Micro nutrient contents of this vegetation were determined
annually in 2002 and 2003. Experimental plots received rains of 606.3
and 857.5 mm during the 2 study years compared to mean growing season
rainfall of 729.8 mm. Micro nutrient contents of these grass plants were
increased significantly by nitrogen and phosphorus fertilizers
application. Contents of micro nutrients after nitrogen and phosphorus
fertilizer treatments, it is determined and ordered for Lotus suaveolens
Cu>Fe>Zn>Mn and for Trifolium angustifolium Cu>Fe = Mn>Zn. Nitrogen and
phosphorus chemical fertilizers influence both micro nutrient mobility
and bioavailability and the effects to these plants may be different.
