What is the primary function of soil in plant growth?
Soil provides essential nutrients, water, and a medium for root growth, supporting plant development.
Why is soil pH important for fertilizer application?
Soil pH affects nutrient availability, with certain nutrients being more available at specific pH levels.
What is the role of nitrogen in plant growth?
Nitrogen is a vital nutrient for plants, contributing to leaf and stem growth by being a key component of proteins and chlorophyll.
Why is it important to understand fertilizer chemistry?
Understanding fertilizer chemistry ensures that the right type and amount of fertilizer is applied to maximize plant growth and minimize environmental impact.
What is a macronutrient in the context of fertilizer?
Macronutrients are nutrients required by plants in larger quantities for their growth, including nitrogen, phosphorus, and potassium.
What is the main effect of too much fertilizer on the soil?
Excess fertilizer can lead to nutrient imbalances, soil degradation, and increased pollution of nearby water bodies.

How can soil texture affect fertilizer application?
Soil texture affects how well nutrients are retained in the soil. Sandy soils require more frequent applications, while clay soils retain nutrients longer.
What is the importance of knowing the nitrogen-to-phosphorus ratio in fertilizers?
The nitrogen-to-phosphorus ratio is crucial in understanding the appropriate fertilizer mix for different plant growth stages.
How does organic matter in soil affect fertilizer application?
Organic matter improves soil structure, increases nutrient retention, and enhances the effectiveness of fertilizers.
