Studies on manufacturing suspension ferilizers on the basis of waste phosphates from polyether production
Solid waste from prodn. of polyesthers (P(2)O(2) 28%, K(2)O 13%, Na(2)O 12%) was mixed with KCl and then dild. with an aq. NaNO(2)-urea soln. and water to form a suspension fertilizer. The suspension showed a good stability (phase sepn. below 18.9% after 336 h of sedimentation).
