Using a mixer to make multinutrient blocks

101. To prepare many blocks at the same time it is possible to use a concrete mixer or a regular feed mixer.

102. The concrete mixer is the same as that used in building construction.

In some places concrete mixers can be rented for a day.

103. To prepare eight multinutrient blocks of 25 kg each, we must do the following.

104. Get the ingredients ready:

- 100 kg of sugar cane molasses;
- 20 kg of urea;
- 10 kg of cement;
- 10 kg of dolomitic lime;
- 10 kg of common salt;
- 10 kg of bonemeal;
- 40 kg of fibre.

105. Start the concrete mixer with the cylinder in a horizontal position and at a slightly lower speed than that used for concrete so that the mixture does not come out of the mixer.

106. Pour the sugar cane molasses and the urea into the machine and let it run until the mixture looks even.

107. Add the:

- common salt;
- cement;
- dolomitic lime;
- bonemeal.

Then let the concrete mixer run for about five minutes until the ingredients are evenly mixed.

108. Now start pouring the fibre slowly into the mixer bucket by bucket and wait each time until the mixture looks even.

109. While the ingredients are being mixed, to save time, we can get the moulds ready.

110. When the mixture is smooth and even, pour it into the moulds.

111. Place the moulds under cover in a dry place, and let the blocks dry out for 24 hours.
