Terrestrial ecosystem functioning affected by agricultural management systems: A review
2020, Soil and Tillage ResearchCitation Excerpt :Fig. 2 summarises main impacts of three basic practices of conservation agriculture i.e. crop diversification, reduced tillage and residue incorporation on bio-physicochemical properties of soil and their effect on mechanisms take part in pesticides’ fate. Accumulation of organic residues is one of most important feature of conservation agriculture, and it generally leads to enhance the interception of applied pesticide especially polar pesticides (Reddy and Locke, 1998; Zablotowicz et al., 1998). This interception differs with type, amount and distribution of organic residues in soil (Sadeghi and Isensee, 1997) and affects the applied pesticides persistence (Kah et al., 2007).
Green manure amendment enhances microbial activity and diversity in antibiotic-contaminated soil
2018, Applied Soil EcologyCitation Excerpt :Because the availability of carbon substrates largely controls microbial growth in soil (Elfstrand et al., 2007), green manure amendments stimulate soil microbial growth and activity (Tejada et al., 2008). Moreover, incorporation of cover crops in a crop production system may impact on both soil biological and chemical processes, affecting the subsequent fate of agrochemicals (Zablotowicz et al., 1998). Previous studies have reported the effect of green manure on weed control, soil chemical/biological properties, crop growth and yield (Tejada et al., 2008; Muchanga et al., 2016).
Transition from flooding to sprinkler irrigation in Mediterranean rice growing ecosystems: Effect on behaviour of bispyribac sodium
2016, Agriculture, Ecosystems and EnvironmentCitation Excerpt :In addition, although the surface soil microbial community and activity may increase under no-tillage management (Soon and Arshad, 2005; Muñoz et al., 2007; López-Piñeiro et al., 2013), this does not always imply that the specific microbial populations involved in the degradation of a compound will be more abundant and therefore that this degradation will be faster (Gaston and Locke, 2000). Indeed, compared with conventional tillage, slower pesticide dissipation rates have been reported under no-tillage or reduced tillage regimes (Gaston et al., 1996; Zablotowicz et al., 1998). Despite aerobic rice cultivation being an attractive alternative to lowland rice in areas where water is the limiting factor, one disadvantage of this management system is the greater amount of weeds (Singh, 2008).
Tillage and fallow period management effects on the fate of the herbicide isoxaflutole in an irrigated continuous-maize field
2012, Agriculture, Ecosystems and EnvironmentCitation Excerpt :Degradation of pesticides can also be modified by cover crops. Bottomley et al. (1999) showed that winter crops increased the mineralisation of 2.4-D in subsurface soil, while others studies showed that degradation could be slowed down according to the type of cover crop residues (Gaston et al., 2001; Zablotowicz et al., 1998). Nevertheless, field experiments with cover crops are mainly focussed on their effects on nitrate leaching.
Agroforestry and grass buffer effects on soil quality parameters for grazed pasture and row-crop systems
2011, Applied Soil EcologyCitation Excerpt :Additionally, plant polysaccharides and fungal hyphae associated with the perennial vegetation help form more stable macroaggregates (Degens, 1997; Oades and Waters, 1991; Tisdall and Oades, 1982). Readily available substrates also contribute to greater microbial and enzyme activity (Zablotowicz et al., 1998). Mungai et al. (2005) found that FDA hydrolase activity was significantly higher in tree rows compared to crop alleys for surface soil in a temperate alley cropping practice and the differences were attributed to tree age and soil water content.
