What is it about?
We have examined the relation of water repellency induced by organic manure amendments to the water entry value and water retention of a Sri Lankan Ultisol.

Why is it important?
Lowered stability of soil aggregates governed by insufficient organic matter levels has become a major concern in Sri Lanka. Although the use of organic manure with water repellent properties lowers the wetting rates and improves the stability of soil aggregates, its effects on soil hydrophysical properties are still not characterized. Our findings revealed that the slight incorporation of hydrophobic organic manure with other common organic manures would not generate unfavorable impacts on soils.
Perspectives
This publication extensively explains the importance of slight increment of water repellent conditions of common organic amendments with special consideration towards a tropical ultisol soil. We have proved that this situation might not cause detrimental impacts on major soil hydrophysical properties. Hence we tried to emphasize the positive impacts of slight increment of water repellency of organic amendments on hydrophysical properties by mixing a small amount of hydrophobic organic manure except the other benefits such as, improved aggregate stability and reduced organic matter depletion which has been revealed by other related research studies.
