APPENDIX 3. Soil and Other Physical Limits for Satisfactory Crop Growth on Organic Soils
1 The clay content of the mineral component must be 18 percent (Soil Survey Staff 1975).
2 n.r. - no restriction
3 Forage crops - although pasture grasses can be grown under the conditions stipulated, the trafficability of animals is uncertain. It is noted that lighter animals like goats may not pose a problem and that the trafficability is probably better where the mineral content is higher.
4 Frequent, but short-term flooding acceptable for clove, nutmeg and rambutan; infrequent, long lasting floods for citrus, durian, guava and mango.
