Sir I have a doubt... ODR value decrease with increase in compaction i.e. bulk density... So according to this, Which type of soil has higher ODR ...sand or clay? (According to me it's clay because it has low BD)
Yes, I also agree with the fact that the sandy soil has better ODR than clay. You may got confused as the porosity of the Clay is higher than the Sand. And Yes, Clay has more porosity but it is effective for the water holding capacity due to ample of small pores. So more water, less air will be there. And we can conclude that the Sandy soil has better aeration status than Clay.
