Sustained rainfall fell throughout the year even though the total amount during the long rainy season period was far below the usual average.
When rainfall does occur during the growing season, it is usually disruptive to production.
When not actually submerged, the soils of the littoral zone are unprotected from extremes of climate, including the direct impact of sunshine and rainfall.
Simple linear regressions were also used to test for relationships between rainfall and mean species richness, percentage of baits attacked, intensities of attack.
No direct relationships were noted between rainfall recorded at the sites and species richness, frequency and intensity of attack on baits.
The sands are mostly well drained but low-lying areas accumulate sufficient clay and fines to retain water for periods after rainfall.
Presence of an adequate water film is related positively with rainfall and negatively with insolation.
The lowest maize yield harvested in 1996/97 under sole maize was attributed to leaching and water logging due to excessive rainfall and lodging.
