In direct seeding, seeds are sown directly in wet/puddled soil, unpuddled soil, or standing water (Kumar and Ladha 2011).
It improves grass density, soil moisture, soil bulk density, standing crop biomass, and soil organic matter, an indicator of increases in soil carbon.
Lack of moisture from snow, soil and standing water in fields will only help to make those frosts more severe.
Total carbon flux has been modeled by taking areal estimates of LU/LC changes of two time periods and carbon factors for soil and standing biomass.
De Jong et al., [13] summarized several studies on tropical ecosystems and observed that on the average the soil and standing biomass compartments are balanced with 120 Mg ha-1.
Plants were established for 8 months in outdoor cultures in waterlogged soil without standing water, and then randomly allocated to water depths from 0 to 0.5 m.

Typha orientalis has received less attention than many other Typha species, but is capable of accumulating very high biomass in the field in environments ranging from waterlogged soil without standing water (Pegman and Ogden 2005) to water depths up to 1.0 m (Froend and McComb 1994; Inoue and Tsuchiya 2009).
All three species grew well in waterlogged soil without standing water, supporting the principle that competition is the major factor driving zonation in shallow water but physiological tolerance controls zonation in deep water (Lenssen et al. 1999; Jung et al. 2009).
For while many regions performed exactly as scientists had predicted -- succumbing to landslides or sprouting bubbling fountains of liquefied soils or standing solid -- many other regions acted quite differently, even in a fashion opposite from what scientists might have expected.
