As part of our Agriculture for Everybody blog series, we are going to see Bed Preparation for Vegetable Farming (Bread Sandwich Method) popularised by Dr. G. Nammalwar.
Length - Can be of any size
Breadth - 2.5 ft to 4 ft (Max)
- Nobody should step on the bed, once the beds are prepared as this will compact / harden the soil.
- Generally, one drip point is required for 2.5 ft breadth size, 2 drip points are required for 4 ft breadth size.
Space between Beds - 1.5 ft to 2 ft (Max)
- This area can be used for irrigation as well as for all the activities like sowing, manuring, harvesting etc
- Remove the Top Soil up to a depth of 1 ft and keep it separate for later use. Another way to identify the top soil is the difference in change of colour between the top soil and the sub soil.
- Loosen the Sub Soil up to a depth of 1 ft which is beneath the sub soil. This basically means, you need to make the compacted or hardened sub soil loose.
- Add a thick layer of Compost on top of the sub soil.
- Where possible Charcoal can also be added on top of the sub soil.
- On top of the Compost or Charcoal place the top soil.
- The bed should be from East to West direction to get maximum sunlight throughout the day.
- Generally, most of the vegetables need full sunlight and hence proper plan should be made to ensure that no shadow falls on the bed.
- Few vegetables may tolerate semi-shadow and these can be planted where shadow falls on the bed.
- If multiple raised beds are made next to each other, can opt for sprinklers for watering.
