Why is maize not planted on the crest of a ridge
Maize, also known as corn, is usually not planted on the crest of a ridge due to several reasons:
1. Wind protection: The crest of a ridge is exposed to high winds as it is the highest point. Maize plants are tall and can be easily damaged or knocked down by strong gusts of wind. Planting maize on the crest of a ridge can result in significant yield losses due to wind damage.
2. Erosion control: Planting maize on the crest of a ridge can contribute to soil erosion. The elevation of the crest accelerates water runoff, potentially leading to the loss of fertile topsoil. To prevent erosion and retain moisture, it is generally recommended to plant maize on the slopes or in the depressions of a ridge, where the soil can be more securely anchored.
3. Water distribution: On the crest of a ridge, water tends to flow down both sides, leaving the maize plants in the center with inadequate moisture. Planting maize on the slopes allows better distribution and retention of water within the soil, promoting optimal growth and development.
4. Nutrient availability: The crest of a ridge may have poor nutrient availability compared to the slopes or depressions. The soils on the slopes often accumulate organic matter, nutrients, and moisture, providing a more favorable environment for maize cultivation.
Overall, planting maize on the crest of a ridge is not conducive to maximum crop productivity and sustainability due to wind damage, erosion risk, water distribution issues, and nutrient limitations. Selecting alternative planting locations on the slopes or depressions of a ridge offers better conditions for successful maize cultivation.
