Is there any possible way of the use of industrial wastes in crop production?
The effect of applied wastes and by-products (flue gas powder,grinding sludge,and metallurgy lime sludge) was examined in nutrient solution and soil experiments.The experimental plant was Zea mays.The relative chlorophyll contents were measured in the second and third leaves of maize.The dry weight of roots and shoots significantly decreased at the flue-gas treatments in the nutrient solution and in soil experiments,too.We would like to find solutions on how to use wastes and by-products in the agricultural crop production practice in our work.In the different industrial procedures and probably during the everyday use some by-products and wastes are generated which have high micro-and macro element content and these do not endanger the environment.They should not be handled as wastes but rather as nutrient amendments.
