N Test Flashcards
What are Nutrients?
Nutrients are essential substances that plants require for growth and development.
What are macronutrients?
Macronutrients are chemical elements required in large amounts for plant growth and development.
What are micronutrients?
Micronutrients are chemical elements or substances required in trace amounts for the normal growth and development of living organisms.
What are the main macronutrients for plants?
The main macronutrients for plants are Nitrogen (N), Phosphorus (P), and Potassium (K).
What is the role of Nitrogen (N) in plants?
Nitrogen promotes leaf growth and chlorophyll production.
What is the role of Phosphorus (P) in plants?
Phosphorus supports root development, energy transfer, and flower/fruit production.
What is the role of Potassium (K) in plants?
Potassium regulates water uptake, enzyme activation, and overall plant vigor.
What are some examples of micronutrients?
Examples of micronutrients include Iron (Fe), Magnesium (Mg), and Calcium (Ca).
What is the role of Iron (Fe) in plants?
Iron is vital for chlorophyll synthesis.
What is the role of Magnesium (Mg) in plants?
Magnesium is a central element in chlorophyll.
What is the role of Calcium (Ca) in plants?
Calcium strengthens cell walls and regulates growth stability.
How do plants absorb nutrients?
Plants absorb nutrients through their roots, using water as a medium for transportation.
What is the importance of nutrient balance?
Maintaining the right balance of nutrients prevents deficiencies or toxicities.
What is root absorption?
Root absorption is the process by which roots absorb nutrients dissolved in water through osmosis and active transport.
What is a Nutrient Solution?
A liquid filled with all the necessary nutrients for plant roots to promote growth, formulated to provide macronutrients and micronutrients in the right proportions.
What are Commercial Nutrients?
Easy to use, require minimal ordering of fertilizers, and very little or no mathematical calculations.
What are DIY Nutrients?
Usually cheaper to mix, gives control over the nutrient mix, and can be customized to the specific needs of the plants being grown.
What is the optimal pH range for soil?
5.5 - 6.5
Why is pH important in Hydroponics?
pH affects the solubility of nutrients in water, influencing their availability to plants.
How can pH be monitored and adjusted?
Using tools like pH meters or pH test strips, and adjusting with pH up/down solutions.
What is the pH scale classification?
pH 7.0 is neutral; below 7.0 is acidic, and above 7.0 is basic or alkaline.
How does soil pH affect nutrient availability?
Soil pH influences both the availability of soil nutrients to plants and how the nutrients react with each other.
What is the importance of pH in hydroponics?
Maintaining the correct nutrient balance and pH is essential for healthy plant growth.
What are the visual symptoms of nutrient deficiencies in fig tree leaves?
Symptoms include deficiencies in nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg).
What tools are used for monitoring and adjusting pH?
Tools for monitoring and adjusting pH are essential in hydroponics.
What is a key takeaway regarding nutrients in hydroponics?
Understanding nutrients in hydroponics is crucial for plant health.
