Smell is the most subtle of senses touched by spring. In spring there is the sweet fragrance of flowers, which is perhaps the first thing many think of. But my thoughts are drawn to subtler scents. In winter the sun is low and weak, giving little light and even less warmth.
Plants receive energy from light through a process of photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow.he makeup of a soil and its acidity determine the extent to which nutrients are available to plants. This pie grapgh informs us what is in the soil and how its composition is layed out. This pie graph was created on Chart Tool.
We are taught in elementary school that in order to grow plants need water, sunshine, and soil. This is a mantra that any fourth grader knows by heart, but it is only partially correct. Plants need water, sunshine, and nutrients. They do not have to get their nutrients from the soil.In soil, the nutrients are dilute and the plant has to spend considerable time and energy spreading its roots to find the nutrients that it needs.ydroponic plants can be grown in water, gravel, sand or simply in the air with an occasional nutrient bath. This is an efficient system and the plants benefit through greater efficiency than soil-based planting.
