    30 Location: Sussex Country: i always thought the idea behind it all was to puncture the lawn (aerate it) then "FILL" the holes with sand (sharp sand is good) the idea being that you"break the compactedness" of the lawn by aeraiting it and all the sand is for is just to stop the holes from closing up I remember the late Geoff Hamilton doingCoarse sand (also known as sharp sand and builder’s sand) contributes to soil drainage and aeration It is inexpensive and very good for gardens in rainy environments, where poor drainage is an issue PerliteHow To Fill A Raised Bed With Healthy Soil (& Save Money!)Unicef Jordan O & M Manual Water Supply Azraq Refugee Camp WASH Section Azraq Refugee Camp Page 5 / 65 PG / 03042019 1 Objective This O & M Manual Water Supply Azraq Refugee Camp is the core document that defines the needs, requirement, processes, elements and timelines to assure a proper and sustainable runningOperation and Maintenance Manual Water Supply
