SPREEDING OR DRYING

• Suitable for hot dry climates, this method consists in spreading within 24 hours of its being voided each day’s output of manure in a thin layer so that it may be subjected to rapid desiccation by sun and wind.
• Rapid and regular daily drying is essential as only the eggs and pre infective stages of struggles are easily destroyed by desiccation. Moreover dry or drying manure does not attract over poisoning flies and any maggets already present therein cease development and die.
• The method should be worked on the “ Three day system” using three areas of ground each just large enough to take one days output of manure when it is spread out thinly. Each area is covered in turn and before re-using an area again the dries along may where necessary be swift raced to one sole for burning.
