Class | Definition |
S1 | Highly suitable: land having no significant limitations for sustained applications to irrigated cropping, or only minor limitations that will not significantly reduce the productivity. |
S2 | Moderately suitable: land having limitations that are moderately severe for sustained application to irrigated cropping, and may reduce the productivity marginally. |
S3 | Marginally suitable: land with limitations that are severe for sustained application to irrigation cropping, and as such reduce productivity significantly but is still marginally economical. |
N | Unsuitable: land with extreme limitations which appear to preclude sustained application to irrigation cropping. |
