The mixture of grains is pierced through a perforated insert and dried to a moisture content of 8g-16%. The dried granules are ready to use Bi as fertilizer.

As can be seen from the above data, the proposed fertilizer is distinguished by a higher mechanical strength and Resistance of the elements of explosives of the mineral nutrition of plants to washout with water. A comparative analysis of the quality of the granules of five compositions of the proposed fertilizer showed that compositions with a ratio of components of 15: 15: 55: 15 and 15: 15: 60: 10 have the best properties.

Field tests to study the effectiveness of granular organo-mineral fertilizers using shale were carried out on the experimental basis of the Dukor of the Institute of Peat of the Academy of Sciences of the Byelorussian SSR.

The compositions of fertilizers are presented in table 2.

Table 3 3. NDS (the smallest difference is) 5%: for potatoes 19 centners ,. on oats - 2.1 cent. Experience error with potatoes. 2/9% with oats -1.8%. The results of the experiment show that granulating clayey sludge with peat and mineral fertilizers and comparing with the known ones gives a statistically significant yield increase equal to 42 c / ha for oats, error of experience 2,96% and 1,8%. The yield of crops using granular fertilizers of formulations 1 and 3 is slightly different from the yield obtained on the granules part 2. For oat, the deviations in the yield are ± 0.5 centner / ha, the seedlings ± .3.5 centner / ha. The proposed organic-mineral fertilizer has a high resistance of mineral components to the effects of soil moisture, structure strength and higher efficiency. . Utilization of 2.5-3.5 million tons of clay-to-salt sludge in the production of complex granular organic fertilizers allows for an additional supply of agricultural 8b to 0.85-1.2 million tons of potash fertilizers in terms of standard fertilizers, i.e. to grow 250-350 thousand tons of grain. In addition, soil salinization was prevented by dumps of clay-salt slimes.
