Adaptability of ring method:

• Suited to smooth gentle and uniform land slope and soil having to moderate to slow infiltration rate.
• Suitable for both row crops and close growing crops.
• Adapted to grain and fodder crops in heavy soils to ensure adequate irrigation.
• Also suitable in very permeable soils which must be covered with water rapidly to prevent excessive deep percolation losses.

Advantages of ring method

• Useful when leaching is required to remove salts from the soil profile.
• Enables the conservation of rainfall and reduction in soil erosion.
• Uniform application can be achieved.
• Even a small streams (2 ltr/sec) irrigation water can be applied efficiently.

Limitations of ring method

• Ridge interfere with the movement of animal drawn or tractor drawn implements for intercultural operations or harvesting of crops.
• Crops yield is substantially low on the ridge and in the lateral channels.
• Problems of lateral drainage.
• High labor requirement in land preparation and irrigation.
• Not suitable for crops which are very sensitive to wet soil condition.
