Objective of the research is to determine
the mineral contents of weed crops intensively grazed by livestock of Central
Anatolian Region. A total of 11 weed crops (Sinapis
arvensis, Lamium album, Malva spp., Convolvulus
arvensis, Chenepodium album, Alhagi spp., Sanguisorba
minor Scop., Amaranthus spp., Taraxacum officinale, Polygonum cognatum and Sorghum halepense)
collected from pastures and field of Kayseri were used as the material of the
research. Plant samples were collected at blooming periods during June of the
year 2011. Samples were dried and mineral contents were determined with 3
replications. Statistical analyses were performed based on randomized block
design.

Phosphorus, Calcium, Potassium, Nickel,
Cadmium, Lead, Copper, Manganese, Sodium, Zinc, Iron, Magnesium and Boron were
determined in the weed plants in dissimilar numbers. The close analysis
indicated that the weed seeds contained Cu 8.115-9.360, Mn 65.905-77.890, Zn
30.405-42.105, Fe 254.0-290.5, Mg 2118.0-2414.0, B 6.385-9.655, Ni
0.2305-0.2945, P 2640.5-3307.5, Ca 8193.0-8965.0, K 10221.51-12332.0, Cd
0.1625-0.2235, Pb 0.3345-0.4160 and Na 1181.51-1475.5 mg kg-1, respectively.
Results indicated that weed plants of Central Anatolia were rich in trace
elements and there was no need for supplemental trace elements.
