Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford

Journal of the Department of Agriculture, Western Australia, Series 4

Lack of oxygen is the major cause of limited plant growth in waterlogged soils. When soils become waterlogged less gas diffuses to and from the roots through the soil pores; there are changes in concentrations of mineral elements in soil solutions; and toxic products of roots and soil microorganisms begin to accumulate. These changes adversely affect germination, growth and development of plants.

Wheat Growth On Saline Waterlogged Soils, E G. Barrett-Lennard

Journal of the Department of Agriculture, Western Australia, Series 4

Studies of the growth of plants on salt-affected soils have focused maily on the effects of salt. However, many salt-affected soils are also subject to waterlogging. Glasshouse experiments conducted by the Department of Agriculture have shown that although wheat growth is not greatly reduced by low levels of salt under well drained conditions, under waterlogged conditions such levels of salt can have a severe effect.

Soil Hardpans And Plant Growth, J W. Bowden, R. J. Jarvis

Journal of the Department of Agriculture, Western Australia, Series 4

When farm vehicles travel over moist soils they can create hardpans which can marledly reduce crop and pasture yields.

Research at Wongan Hills Research Station has shown that plant growth and nutrient uptake were affected for at least eight years after the original workings caused the hardpan.
