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.
A plant needs nutrients to survive. Most of these are provided by the soil, but soil varies tremendously in nutrient amounts, soil type, pH, and nutrient availability. The three main nutrients that have been identified as absolutely necessary for plants are nitrogen (N), phosphorus (P) and potassium (K). These three are also known as macronutrients, and are the source of the three numbers commonly found on organic fertilizer labels. The numbers found on our All-Purpose Fertilizer, for example, are 5-5-5. This is the percentage by weight of the N, P, and K found in the fertilizer. So whatâs so important about nitrogen, phosphorus and potassium?
