Sugar has a low water potential, which means water would move outside of the cell, which is why the mass of the potato would decrease. campground los angeles caAt a potential of 0 kPa, soil is in a state of saturation. At saturation, all soil pores are filled with water, and water typically drains from large pores by gravity. At a potential of −33 kPa, or −1/3 bar, (−10 kPa for sand), soil is at field capacity. Typically, at field capacity, air is in the macropores and water in micropores. Field capacity is viewed as the optimal condition for plant growth and microbial activity. At a potential of −1500 kPa, soil is at its permanent wilting point, at which plan… first time home buyer incentive 2018
