Weed management between coffee inter rows plays a key role in minimizing soil degradation processes. Soil structure and, consequently, its pore size distribution (PSD), water retention (SWRC) and availability can be greatly affected by the weed contr

Brazilian soils that present extremely hard sub-superficial horizons when dry and friable when humid are similar to the Australian and South African hardsetting horizons whose hardness can be mainly related to low crystallinity. Studies involving ref
