Do anionic polyacrylamide polymers affect plant growth?

Various anionic polyacrylamide polymers (PAMs) are frequently used to improve soil properties and reduce erosion. However, the effects of their application on plant growth remain unclear.

Does a linear Pam affect plant growth?

However, the effects of their application on plant growth remain unclear. Aggregate-free loess with high water holding capacity was used as growing substrate to test the effects of two rates (10 and 40 kg ha −1) of a linear PAM on the growth of maize (Zea maize L.) for a period up to one month.

Does Pam application affect maize growth?

Soil water content and age significantly affected these variables, but none variables were affected by PAM application. The effects of PAM application on maize growth were largely masked by the non-structural loess, tended to be age and soil-moisture specific, and were modulated by the rhizodeposition processes.

Does polyacrylamide affect water consumption and rhizodeposition?

Two rates (10 and 40 kg ha −1) of an anionic linear polyacrylamide were applied to non-aggregative and high-water-absorbing loess for a period up to 1 month. The effects of PAM on water consumption, biomass accumulation, and C assimilation and allocation in maize and rhizodeposition in soil were tested.

Does Pam affect plant growth?

As a result, the absence of negative effects of PAM on plant growth suggests that the PAM can be applied at least up to 40 kg ha −1 without notable negative effects on plant growth. Abiven S, Menasseri S, Chenu C (2009) The effects of organic inputs over time on soil aggregate stability—a literature analysis.

Does Pam affect water consumption and biomass accumulation in maize and rhizodeposition?

The effects of PAM on water consumption, biomass accumulation, and C assimilation and allocation in maize and rhizodeposition in soil were tested. Soil water content and age significantly affected these variables, but none variables were affected by PAM application.
