“…abundance and diversity, soil microbial respiration, biomass or activity. Several studies (Doran 1980;Gupta and Germida 1988;Vargas Gil et al 2008) stress that, unlike monoculture, crop rotation can stimulate soil biodiversity and biological activity through changes in the soil habitat, favouring the development of specific microbial communities (Meriles et al 2006). Accordingly, because of the different quality and amount of exudates and organic components from root systems and crop residues, some groups of microorganisms can be differently influenced by crop sequence, supporting the diverse results obtained in this work.…”

Soil microbiological and chemical aspects were evaluated to determine the effects of conservation tillage and crop rotation on soil fertility over a 16-year period. A field trial was established to compare two cropping systems (continuous soybean and maize/soybean, soybean/maize rotation). In addition, maize (Zea mays L.) and soybean (Glycine max L., Merr) were grown in two different tillage systems: no tillage and reduced tillage. Soil populations of Trichoderma spp., Gliocladium spp. and total fungi were more abundant when maize or soybean were under conservation tillage and in the maize/soybean and soybean/ maize rotation, than in continuous soybean. Furthermore, higher levels of microbial respiration and fluorescein diacetate hydrolysis (FDA), were recorded under no tillage systems. However, soil counts of Actinomycetes and Pythium spp., and Pythium diversity together with soil microbial biomass were not affected by the field treatments. To establish a correlation with soil biological factors, soil chemical parameters, such as pH, organic matter content, total N, electrical conductivity, N-NO 3 -and P were also quantified, most of the correlations being significantly positive. Under no tillage there was a clear increase of the amount of crop residues and the C and N soil content due to the presence of residues. Also the distribution of crop residues in surface soil due to zero tillage and the quality of these residues, depending on the crop rotation employed, improved on soil biological and chemical characteristics. Crop yield was also enhanced by zero tillage through the management of residues. Although yield values were not directly associated with the development of microorganisms, both yield and microorganisms were influenced by crop management. These results suggest that measuring soil properties over a long period helps to define effective management strategies in order to preserve soil conditions.

“…Means et al (2007) detected a signiûcant increase in soil Fusarium within two weeks after glyphosate was applied at recommended rates in the ûeld. Meriles et al (2006) verified that the population growth and sporulation of soil Fusarium spp. increased after glyphosate application to soils containing maize or peanut crop residues compared with lower Fusarium populations in similar fallowed soils lacking crop residues.…”

Weeds are generally hardy species having fast growth, deep root system and capable of competing very efficiently with cultivated crops for the available resources and adversely affect the crop growth and yield. Weed management systems that rely on post emergence control assume that crops can tolerate competition for certain periods of time without suffering yield losses. Initial slow growth particularly at early crop growth stages and wider plant spacing of maize crop encourages fast and vigorous growth of weeds. It is of paramount importance that, competition from weeds must be minimized to achieve optimum yield. Among the different weed control methods, chemical method bears many advantages in suppressing weed growth and to get healthy and vigorous crop stand. Non-selective herbicide molecules with a variety of mode of action were discovered, developed and marketed for successful weed control programme.

“…This effect was larger in soils that had greater previous exposure to glyphosate. Other studies have shown that glyphosate use is associated with an increase in the plant pathogens Fusarium and Pythium [42]. Glyphosate can stimulate the growth of mycorrhizal fungi in vitro.…”
