This in the article Based on FeCl ₃ and EDTA-Na₄ (C₁₀H₁₂ N₂O₈Na₄). taken liquid chelate "Iron chelate " fertilizer complex (Fe-EDTA)” thermogravimetric (TGA), differential thermal (DTA) and scanner electronic microscopy energy-dispersive in spectroscopy (SEM-EDS) methods research TGA analysis was done . as a result sample up to 800°C when heated general mass loss of 24,140 % organization reached , main thermal effects at temperatures of 104.97°C, 162.84°C, 237.28°C, 276.65°C and 367.75°C observed SEM- EDS analysis sample contains the elements C (42.52%), O (38.49%), Na (6.68%), Cl (1.78%) and Fe (8.95%) existence showed . Obtained results chelate fertilizer thermal stability and element composition assessment opportunity gave .
