Biochar from water hyacinth (Eichornia crassipes) and its impact on soil biological activity

Optimal conditions for the catalytic and non-catalytic pyrolysis of water hyacinth

“…Moreover, China lacks natural predators or natural mechanisms to control water hyacinth [5], which means that has a rapid growth rate. The uncontrolled growth of water hyacinth has had a number of negative impacts, such as (1) a reduction in the number of fish; (2) obstruction of river courses, reservoirs and water channels [6]; (3) increased evapo-transpiration [2]; and (4) interference with fishing and hydroelectric schemes [1]. Therefore, it is necessary to deal with water hyacinth effectively and economically.…”

“…Water hyacinth (Eichornia crassipes) originally comes from the Amazon basin in South America [1] and is a free floating aquatic and recalcitrant weed [2] that has spread throughout the world [3]. In China, more than 66% of reservoirs and lakes are eutrophic, of which 22% are highly eutrophic [4].…”

Chemical soil attributes of Cerrado areas under different recovery managements or conservation levels

“…Masto et al (2013) observed higher pH values, microbial activity and vigorousness of seedlings, which are the result of an application of biochar from E. crassipes in soils, or contains a mixture of aquatic macrophytes with variation in its nutritional composition. Sakadevan and Bavor (1999) as well as Henry-Silva and Camargo (2008) acknowledge that the variation in nutrient absorption of macrophytes is caused by different characteristics of the water body and the time spent in the efflux.…”

Potential value of biochar as a soil amendment: A review

“…The higher productivity of "Terra Preta" soils that were regularly amended with biochar and other organic materials than un-amendment soil, led to world-wide interest in applying biochar to agricultural soils. Increasing data show that amending soil with biochar has remarkable effects on the physical, chemical, and microbiological properties of soil [19][20][21]. The most notable effects may be the increase in the stable soil C pool and reduced greenhouse gas emissions [22,23].…”
