DESCRIPTION: The function of this implement is bo make small furrowt, or corrugations, for distributing water over a field.

The corrugations are run down the slope of the land. This implement can be used after the field has been broadcast seeded or before row-crop planting.

For maximum water carrying capacity, the inside surfaces of the corrugations ehouic' be compressed and smooth. To achieve this, ballast can be adied to the implement as required.

The spacing of the corrugations will depend »yon how rapidly the the water moves laterally through the soil. Too lighter the soil texture, the wider a^art the corrugations can be.

The implement design shown can be modified in size to suit animal-draught or tractor-hitching &s required.

Note: The figures in brackets are in millimetres.
