Superabsorbent Polymers and Superabsorbent Polymer Composites
This article briefly describes the general aspects and cross-linking polymerization of superabsorbent polymers (SAPs) and superabsorbent polymer composites (SAPCs). Research and development of SAPs has become very active after the Northern Region Laboratory of the United States Department of Agriculture invented the first SAP, used as a soil conditioner. Based on the advancements in organic/ino...
متن کاملCrack Mitigation in Concrete: Superabsorbent Polymers as Key to Success?
Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these problems. At an early age, the absorbed water by the SAPs may be used to mitigate autogenous and plastic shrinkage. The formed macro pores may...
متن کاملAlum-Treated Poultry Litter as a Fertilizer Source
Alum used for poultry houses is sold under the commercial name of “Al+ Clear” in either liquid or dry form. Alum should not be confused with other litter treatment chemicals such as “PLT” (poultry litter treatment), as PLT is comprised mainly of sodium bisulfate (NaHSO4). Although PLT is effective at reducing ammonia levels, pathogens in house, energy costs, and potentially increasing forage yi...
متن کاملEffect of chemical and microbial amendment on phosphorus runoff from composted poultry litter.
Environmental impacts of composting poultry litter with chemical amendments at the field scale have not been well quantified. The objectives of this study were to measure (i) P runoff and (ii) forage yield and N uptake from small plots fertilized with composted and fresh poultry litter. Two composting studies, aerated using mechanical turning, were conducted in consecutive years. Composted litt...
متن کاملAlum amendment effects on phosphorus release and distribution in poultry litter-amended sandy soils.
Increased poultry production has contributed to excess nutrient problems in Atlantic Coastal Plain soils due to land application of poultry litter (PL). Aluminum sulfate [alum, Al(2)(SO(4))(3).14H(2)O] amendment of PL effectively reduces soluble phosphorus (P) in the PL; however, the effects of these litters when added to acidic, sandy soils are not well understood. The objective of this study ...
