Microbes can help pea and bean plants by giving them important nutrients needed for healthy growth. For example, there are microbes that can add nitrogen, which is essential to plant growth.
For plants, phosphorus is an important nutrient because they need it for cell division and growth. Without this nutrient, plants can exhibit signs of stunted roots and leaf problems. Two other important nutrients needed by plants are nitrogen and potassium.
photosynthesis being the process by which plants manufacture their own foof is important to plant for 1. growth 2. nourishment

Cell division is essential for growth in plants
Earthworms are an important part of the soil environment, and the growth of plants. Oil is deadly to earthworms.
