I have followed a procedure to find out WHC of some sieved soil. I have also got the moisture % content of the soil. From this I have calculations that tell me exactly how much water to add to reach 60% WHC. However, after added this amount of water I can see the water leaching through the mesh bottom, suggesting that its beyond 60%
My question is, should 60% WHC happen instantly, or should I wait a certain period of time for the water to be absorbed?
As I need to weigh the wetted soil and maintain that weight. However, columns initially wetted weight more than the next day so I'm not sure which is the true WHC.
We did the same thing on our soils and it is true that they were very wet. Our mistake was the size of the mesh that ultimately allowed all fine particles to pass. Then it was good to wait 48 hours for the percolation of soil water after humidification (24 h).
