(1). Procedure of preparation of compost

Materials and method

(A): Required materials (same as in long method)

Combination 01:

  • Small pieces of wheat straw: Its maximum length should be 10-15 cm. Quantity is 250 kg.
  • Or, small pieces of paddy straw Its maximum length should be same as in wheat straw. Quantity is also same.
  • 20-25 kg husk of wheat or paddy.
  • 4 kg of ammonium sulphate or calcium ammonium nitrate.
  • 3 kg of urea.
  • 4 kg of MOP or muriate of potash.
  • 20 kg of gypsum.
  • 40 kg of melatonin.

Combination 02:

  • 250 kg of wheat straw.
  • Or, 400 kg of wheat straw.
  • 9 kg of ammonium sulphate or calcium ammonium nitrate.
  • 4 kg of urea.
  • 9 kg of super phosphate.
  • 30 kg of wheat husk.
  • 12 kg of gypsum.
  • 10 kg of calcium carbonate.

*Note: Apply 6 kg of cotton seeds, if you are using paddy straw.

Combination 03:

  • 300 kg of wheat straw.
  • 25 kg of wheat husk.
  • 9 kg of ammonium sulphate or calcium ammonium nitrate.
  • 3 kg of super phosphate.
  • 4 kg of urea.
  • 3 kg of muriate of potash or sulphate of potash.
  • 5 kg of molasses.
  • 30 kg of gypsum.
  • 50 ml of melatonin.
  • 25-30 ml of nemagon.

(B): Short or pasteurization method of compost making for button mushroom

(B01). Stage one

Step 01:

  • We use a cement floor.

Step 02:

  • Make a layer of 30 to 40 cm using paddy straw.

Step 03:

  • Spary water on it.

Step 04:

  • Turn is upside down for up to 3 to 4 days, and keep spraying water.

Step 05:

  • Mix urea, wheat husk, calcium ammonium nitrate and other materials except gypsum on day 4.

Step 06:

  • Turn the heap of straw after each 48 hours.

Step 07:

  • Mix gypsum after the third turning.

Step 08:

  • Fill the compost in tray on day 7, and take it to pasteurization chamber.

Turning the heap for long method

  • First turning of the straw heap: On 6th day.
  • Second turning of the straw heap: On 10th day.
  • Third turning of the straw heap: On 13th day.
  • Fourth turning of the straw heap: On 16th day.
  • Fifth turning of the straw heap: On 19th day.
  • Sixth turning of the straw heap: On 22th day.
  • Seventh turning of the straw heap: On 25th day.

(B02). Stage two

Step 01:

  • Bring the compost in pasteurization chamber.

Step 02:

  • Increase the temperature of chamber to 45°C.

Step 03:

  • Close the chamber to make it a heat barrier.

Step 04:

  • Raise the temperature up to 50 to 52°C, and off the supply of warm vapor.

Step 05:

  • Main this temperature (50 to 52°C) for 2 to 3 days.

Step 06:

  • Again, maintain the temperature up to 58 to 60°C for 2 to 3 hours.

Step 07:

  • Open any window of the chamber to subside temperature.

Step 08:

  • In the next 12-14 hours, temperature will be 40 to 45°C.

Step 09:

  • Close the window for 2 to 3 days to maintain this temperature (40 to 45°C).

It is the temperature stabilizing phase. Now, thermophilic bacteria will convert ammonia to organic matter. It will increase the percentage of ammonia up to 2.2 to 2.3%, which help the growth of bacteria.

(2). Why is composting necessary?

  • Straw become soft.
  • Proper aeration.
  • Availability of organic nutrients.
  • Proper development of mushroom body.
  • Increase water holding capacity of growing media.
  • Conversion of toxic ammonia into carbonic matter.

(3). What are the necessary qualities of a compost?

  • It should be free from ammonia toxicity.
  • pH should be 7 to 7.5, it shouldn’t more than 8.
  • Optimum moisture content for the proper growth and development of mushroom is 68, so the required moisture content is 67-70%.
  • Nitrogen content should be 2.2 to 2.5%.
