What does nutrient stratification indicate about soil health?

Nutrient stratification refers to the phenomenon where different nutrients are concentrated at varying depths within the soil rather than being evenly distributed. This can significantly influence plant growth and health because when nutrients are stratified, certain plant roots may have access to beneficial nutrients while other roots may not. This uneven distribution can lead to deficiencies in some areas and surpluses in others, affecting overall plant development and the ecosystem’s nutrient cycling.

When nutrients are found in layers, it can limit the effectiveness of nutrient uptake by plants, especially if they are not deep-rooted or if their root systems do not reach the stratified layers. This stratification often results from factors such as irrigation practices, soil texture, organic matter accumulation, and the activity of soil organisms. Therefore, understanding nutrient stratification is essential for developing appropriate soil management practices that can enhance soil health and improve crop yields.

The other options do not accurately capture the implications of nutrient stratification. Soil compaction reducing nutrient availability does not relate to the stratification concept, while a balance of pH levels addresses soil fertility but isn't directly linked to nutrient stratification. The idea that all nutrients are uniformly distributed contradicts the very definition of stratification.
