Making a trial multinutrient block

39. Before making the whole batch of mix, we should make a trial multinutrient block.

40. To make the trial block add together:

- 5 kg sugar cane molasses;
- 1 kg urea;
- 500 g cement with 0.25 litre (250 g) water;
- 500 g dolomitic lime;
- 500 g common salt;
- 330 g (one- third kg) bonemeal
- 2 kg fibre.

41. Then, stir and knead all the ingredients until they look evenly mixed.

42. Last, pour the mixture into moulds and leave it for a day to let the multinutrient blocks harden.

43. Take the blocks out of the moulds and check them.


44. A multinutrient block is good when:

- The ingredients are very well- distributed throughout the block.
- It does not have lumps of urea and lime.
- It is hard.
- It is resistant.
- It is sticky.

45. Blocks should be too hard to squash between our fingers.


6. Blocks should be resistant enough not to break when a person steps on them.


47. When we hold a block, our hands should feel the sticky sugar cane molasses.


48. Attention! When the blocks do not feel sticky, we need to increase the amount of molasses we put into the mixture.
