Plant nutrition

• What process do plants use to make their own food?

  Photosynthesis
• What happens to plant A due to nitrogen deficiency?

  It has stunted growth and yellow leaves
• What ion should plant A absorb from the soil?

  Nitrate ions
• Why is magnesium important for plants?

  It is needed to make chlorophyll
• What is the effect of magnesium deficiency on plant B?

  It has yellow leaves and stunted growth
• What deficiency does a plant with older yellow leaves and stunted growth have?

  Potassium deficiency
• What are the symptoms of potassium deficiency in plant C?

  Older leaves are yellow, veins remain green
• What role does potassium play in plants?

  It is needed for growth and immunity
• What deficiency does a plant with darker older leaves, some fallen off and purple veins have?

  Phosphate deficiency
• What are the symptoms of phosphate deficiency in plant D?

  Older leaves are darker green, some fallen off
• Why is phosphorus important for plants?

  It is involved in energy transfer
• How does nutrient availability affect farmers?

  It impacts growth rate and yield size
• What is hydroponics?

  A method of growing plants without soil
• How do farmers control nutrients in hydroponics?

  By suspending roots in nutrient-rich water
• What is crop rotation in traditional farming?

  Changing crops grown in a field periodically
• What do artificial fertilizers contain?

  Nitrogen, phosphorus, and potassium
• What are natural fertilizers made from?

  Human or animal waste
• What nutrients do feces and urine provide for plants?

  nutrients needed for growth
• What nutrients do plants require for healthy growth?

  • Nitrogen
  • Magnesium
  • Potassium
  • Phosphorus
• What happens to plants if they do not receive enough nutrients?

  • Stunted growth
  • Yellowing leaves
  • Poor fruit yield
  • Increased susceptibility to diseases
• What are the impacts of nutrient deficiencies on farming?

  • Slower growth rates
  • Smaller yields
  • Less fruit production
• What are the benefits of hydroponics compared to traditional farming?

  • More control over nutrients
  • No soil required
  • Potential for faster growth
• What are the differences between artificial and natural fertilizers?

  • Artificial: chemically manufactured
  • Natural: derived from organic matter
• What is the significance of crop rotation in agriculture?

  • Prevents nutrient deficiency in the soil
  • Reduces pest and disease buildup
  • Enhances soil fertility
