 Soil is the earth for living things; mankind, biodiversity and many living creatures. We need food, shelter and place to live healthily and happily. How do you think which thing is giving these things. Of course, soil. Soil is more powerful than you think. At university, what I learn about the soil is that the soil has nutrient which is needed to grow for the plant. In planting agricultural crops, after you plant the paddy, you can¡¯t grow another paddy after you reaping the previous one. You have to plant another crop plant like pea in order to fill the protein for the soil. For our forest tree species, if you plant mono crop in one field, you can grow them for a short year and you have to abandon that field after cutting down the tree because the soil can¡¯t give protein to another tree plants. You have to wait for many years to recover the soil. If you don¡¯t like that condition, you should choose many plant species to plant together which must have mutual relationship. And then the biomass which is the leaf falling from the trees will decay and these will give nutrient to the soil again. So that in order to protect the soil, many professionals presented shifting cultivation is bad and we should use sustainable plantation methods like choosing seasonal crops which is fit with soil properties and recovering the soil. After raining, we need soil to absorb the rainwater in order not to encounter the event of flooding. Nowadays, in the urban cities, many buildings are covering the soil and to touch the soil with our feet become rarer things. Our body is organized with four elements, soil, water, air and heat according to the Bible. To get food, we need soil to plant. For the place, we also need soil to build. Soil is different in color according to the topography. In Myanmar, the highland regions are covered with highly leached, iron-rich, dark red and reddish brown soils. The lowland regions are covered with alluvial soils, mainly silt and clay. In the dry central region, red brown soils rich in calcium and magnesium are found. Therefore, healthy soil can give more nutritious food for our living things and helps the environment to be cleaned. |
