Grade 6 Agriculture Conserving Our Environment – Creeping Crops Notes

Conserving Our Environment — Creeping Crops

What are creeping crops?

Creeping crops are plants that grow low and spread across the ground. Their stems or vines creep along the soil instead of growing tall. They cover soil like a green carpet.

Why are they good for our environment?

• Stop soil from washing away when it rains (prevent erosion).
• Keep soil moist by blocking sun and wind (conserve water).
• Reduce weeds because the creeping plants cover the ground.
• Some add nutrients to the soil (for example, groundnuts are legumes).
• Provide food for families (sweet potato leaves and tubers, pumpkins, groundnuts).

Common creeping crops in Kenya

• Sweet potato (vines spread and give tubers underground).
• Groundnuts (peanuts) — grow low and fix some nitrogen.
• Pumpkin and squash — big leaves that protect soil.
• Cucumbers — spread on the ground in gardens.
• Cover crops like mucuna or cowpea — used to protect soil between main crops.

How creeping crops help a Kenyan farmer (simple examples)

If a farmer grows maize on a slope and plants sweet potato or pumpkin between rows, the creeping vines help hold the soil during heavy rains. This means less soil ends up in rivers and the farmer keeps the good soil on the farm.

How to plant and care for creeping crops (easy steps)

1. Choose a place with enough sun (most creeping crops like some sunlight).
2. Make small ridges or mounds for tuber crops like sweet potato.
3. Plant vines or seeds with enough space so they can spread (read seed packet or ask an extension officer).
4. Water regularly until plants grow strong, then water less often to save water.
5. Allow vines to cover bare soil; do not remove them unless they are pests.

Tips for conserving soil and water

• Use creeping crops between rows of other crops (intercropping) to protect the soil.
• Keep some crop residue as mulch — it breaks down and makes soil healthy.
• Plant on contour lines or along small terraces on slopes to reduce run-off.
• Rotate crops each season to keep soil healthy (do not plant same crop every year).

Quick activity (in class or at home)

Draw a small garden (A4 paper). Show where you would plant maize and where to put creeping crops like sweet potato or pumpkin to protect the soil. Colour the leaves green and the soil brown.

Glossary (easy words)

Soil erosion — when soil is moved by rain or wind and lost from the farm.
Mulch — dead plant material placed on soil to keep it cool and moist.
Intercropping — growing two or more crops together in the same field.
