The present research was carried out to determine the content of essential macro nutrients (N, P, K and S) as well as Fe, total organic carbon and total organic matter in textile sludge of Apex Weaving and Finishing Mills Ltd., Gazipur, Bangladesh and assess its possibility to use as a soil conditioner or fertilizer in agricultural land. The results revealed that plant macro nutrients Nitrogen (N), Phosphorous (P), Potassium (K) and Sulphur (S) were found in significant amount compared to some commonly used organic manures. The range of various macro nutrients was 1.53-2.37, 0.09-0.14, 0.11-0.17 and 2.69-3.42% for N, P, K and S, respectively. The concentration of iron (19.52%) was also very high in the sludge than that of in soil. Moreover; total organic carbon (19.89%) and total organic matter (34.67%) were abundantly available in sludge. In addition, thermal study explores that after 400 °C the sludge was thermally stable and it was also confirmed by IR study that dried sludge samples showed significant presence of water at room temperature while the samples heated up to 400 °C, the presence of water was barely indicated.
