“…Researchers have utilized this capability in agriculture in an effort to increase infiltration and reduce erosion associated with rainfall and irrigation. While much research has focused on rainfall and/or sprinkler applications (Sojka et al, 2007; Abu‐Zreig et al, 2007; Petersen et al, 2007), this report is concerned with surface irrigation applications.…”

Two formulations of water-soluble anionic polyacrylamide (WSPAM) are used in agriculture to reduce erosion and manage infi ltration in furrow irrigations, although few if any reports have compared their eff ectiveness. A control and two WSPAMs, a granular form and the inverse emulsion, or oil-based liquid form, were applied to irrigation water supplied to furrows formed in a silt loam soil with 1.5% slope during each irrigation from 1993 to 1999. Stock solutions prepared from the two WSPAMs in tap water were injected into furrow infl ows to attain a concentration of 10 mg L −1 only during furrow advance. During irrigations, furrow infl ow and runoff rates, and runoff sediment concentrations were measured. Crop yields were measured in fi ve of the 7 yr. Relative to controls, both WSPAM treatments reduced runoff sediment loss equally well, decreasing soil losses by 84% per irrigation, and prevented the loss of 47.8 Mg soil ha −1 over the 7-yr period. Th e yearly soil loss reductions produced by WSPAMs ranged from 66 to 99%, and may refl ect changes in the electrical conductivity (EC) of the irrigation water. Both WSPAM treatments increased the proportion of applied irrigation water that infi ltrated into newly formed furrows, but the emulsion produced the greatest overall increase in water infi ltration fraction. As a class, WSPAM treatments increased yields by 14.3% for bean ('Viva Pink' Phaseolus vulgaris L.) and 4.5% for silage corn (Zea mays L.), suggesting that the cost of WSPAM applications may be recoverable. While the two WSPAM formulations provide equivalent erosion protection, diff erences in infi ltration eff ects, product costs, and potential environmental impacts should be considered when selecting the formulation.

“…Higher rates of PAM might have had stronger effects as frequently showed in other studies, because higher application rate provides more ion charges that contribute to the flocculation processes, thus improve the soil structure and WHC (Levy et al 1995;Abu-Zreig et al 2007). However, in common agricultural practices, PAMs are applied at rates of 1 to 100 g m −3 in furrow irrigation water, corresponding to 1-100 kg dry PAM per hectare (Sojka et al 2007;Entry et al 2008).…”

“…PAMs can also preserve plant-available water in soils so as to maintain sufficient soil moisture (Nadler and Steinberger 1993), thus increase water use efficiency and reduce water stress during drought events. Positive effects of PAMs on crop yields and growth activities can be found in Martin (1953), Bjorneberg et al (2003), Abu-Zreig et al(2007) and Lentz and Sojka (2009), etc. Conversely, PAM application could also block the physiological activities of plant growth. Specifically, PAMs can clog pores in soil aggregate surfaces because of their high viscosity and molecular weight (Malik and Letey 1992).…”

Aims 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. Methods 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. The PAM effects were evaluated at three levels of soil water content (SWC) and three plant ages, based on water consumption, shoot and root biomass, as well as allocation of recently assimilated C in plants and soil using 14 C labeling. Results Both SWC and maize age significantly affected water consumption, biomass accumulation, and 14 C allocation in plant parts and soil. Even though consistent increases in plant biomass and total assimilated 14 C were observed, the effects of PAM application were insignificant on either of these variables. Conclusions The effects of PAM application were directly connected to soil rather than to maize, and could be masked by the non-structural loess. The effects tended to be age and soil-moisture specific, and were modulated by the rhizodeposition processes. The possible mechanisms of PAM application on plant growth were also discussed.

“…However, ponds represent a large capital investment and permanently occupy land. The use of polyacrylamide blocks or zeolite filters located at key structures/ discharge points have shown promise to trap soluble nutrients and sediments in arid environments (Zreig et al, 2007). Limited research has been conducted so far by UF/IFAS on this topic, but engineering firms have successfully used this technology on construction sites throughout Florida.…”

The success of the best management practices (BMPs) program for vegetables in Florida is measured by the level of BMP implementation and the improvement of water quality. Both require keeping water and fertilizer in the root zone of vegetables. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension Vegetable Group has identified the fundamental principles of 1) basing UF/IFAS production recommendations on the rigors of science and the reality of field production; 2) replacing the out-of-date paradigm “pollute less by reducing nutrient application rates” with “improve water management and adjust fertilizer programs accordingly”; 3) engaging growers, consultants, educators, and regulators in open-channel discussions; and 4) regularly updating current fertilization and irrigation recommendations for vegetables grown in Florida to reflect current varieties used by the industry. The group identified 1) developing ultralow-flow drip irrigation; 2) assisting conversion from seepage to drip irrigation; 3) using recycled water; 4) developing controlled-release fertilizers for vegetables; 5) developing real-time management tools for continuous monitoring of soil water and chemical parameters; 6) developing yield mapping tools for vegetable crops; 7) developing and testing drainage lysimeter designs suitable for in-field load assessment; and 8) using grafting and breeding to develop commercially acceptable varieties with improved nutrient use efficiency by improving morphological, biochemical, and chemical traits as new strategies to keep nutrients in the root zone. These strategies should become funding priorities for state agencies to help the vegetable industry successfully transition into the BMP era.
