In our gardening class in Buddha garden, to understand the difference in the soil in different places, we took samples of soil from various parts of Buddha garden.
One from a fertile bed, one from near the pond and one from a bed in the process of being made very fertile.
Soil samples were of different shades.We observed each sample and concluded that:
1.The darker the soil the more moisture it has.
2.The blacker the soil the more organic matter in it.
3.The soil near the pond had a high quantity of silt thus it was a lighter brown.
4.The soil from the fertile bed was very dark and black as it was full of moisture and organic matter.
5.The soil from the bed which was not yet very fertile was lighter than the complete bed but darker than the soil from near the pond.
