Question 2

Why is soil testing important in nutrient management?

Accepted Answer

It identifies nutrient deficiencies and informs appropriate fertilizer use.

Answer

It helps to reduce fertilizer costs.

Answer

It ensures that fertilizers are applied in excess.

Answer

It eliminates the need for fertilizer applications.

Question 3

What is the significance of applying fertilizers based on crop nutrient requirements?

Accepted Answer

It ensures the plants get the nutrients they need, improving crop yields and reducing waste.

Answer

It reduces the overall fertilizer cost.

Answer

It increases the chance of nutrient leaching into water sources.

Answer

It encourages the use of only organic fertilizers.

Question 4

What is the role of application planning in nutrient management?

Accepted Answer

It ensures that fertilizers are applied at the right time and in the right amounts.

Answer

It ensures that fertilizers are applied randomly without concern for plant needs.

Answer

It increases the frequency of fertilizer applications.

Answer

It decreases the cost of fertilizers.

Question 5

What are the potential consequences of improper fertilizer application?

Accepted Answer

It can cause nutrient runoff, pollution, and plant damage.

Answer

It ensures faster plant growth.

Answer

It improves the water retention capacity of soil.

Answer

It reduces the need for soil amendments.

Question 6

What is the importance of timing in fertilizer application?

Accepted Answer

It improves nutrient efficiency and minimizes losses.

Answer

It reduces the risk of plant damage.

Answer

It makes the fertilizer dissolve faster.

Question 7

Why is it important to consider environmental factors when applying fertilizers?

Accepted Answer

It helps reduce nutrient loss and minimizes environmental harm.

Answer

It ensures fertilizers are applied evenly.

Answer

It allows for increased application rates.

Answer

It speeds up the fertilization process.

Question 8

What is the relationship between nutrient management and crop rotation?

Accepted Answer

Crop rotation helps improve soil health and nutrient management efficiency.

Answer

Crop rotation has no effect on nutrient management.

Answer

Crop rotation increases the need for fertilizers.

Answer

Crop rotation is irrelevant to fertilizer planning.
