At present, the pilot plot of Yang na trees planting in the compound of The Royal Chitralada Projects has become a Yang na wood in the middle of the city, flourishing and shady and serving as a place of study on plant breeding.
The peat commonly found in southern provinces is a highly acid kind of soil. People were unable to do farming there. His Majesty considered this his duty to find a solution. In 1985, an organic fertilizer factory was set up at The Chitralada Projects with a peat improvement project to be conducted there. Peat was brought from the South for tests. Different kinds of substances were mixed with it one after the other to find out how effective each is in reducing the acid content in the mixture. Moreover, surplus farm materials, bits of weeds, waste water containing yeast dregs released from breweries, were also used to produce compost.
All the above are The Royal Chitralada Projects conducted inside Chitralada Villa that have not only made this royal residence of King Bhumibol of Thailand quite unlike any other royal palace in the World in appearance, but have brought about enormous benefits to the Thai people as a whole.
