“…Many important microbial processes can be infl uenced by minerals, including energy generation, nutrient acquisition, cell adhesion, and biofi lm formation (Hochella 2002 ;Brown et al 2008 ). In doing so, SOM largely determines the physical, chemical, and biological qualities of a soil (Stevenson 1994 ;Etebu and Osborn 2012 ). Soil organic matter (SOM) plays very signifi cant roles in soil.…”

“…The adsorption processes, mineral dissolution of acid functional groups, and the cation exchange capacity depend on the pH. The pH affects the microbial diversity and activity, which in turn, significantly affects the decay rates of plant residues, affecting the content of organic matter in the soil [29]. The pH is an indicator of an abnormal situation in soils, when it reaches boundary values.…”

The knowledge of the soil quality plays a vital role in the agricultural sector. Despite its importance, there is scarce scientific information concerning this regard. The objective of this research is to develop a methodology to identify and select the most appropriate indicators of Soil Quality Index (SQI) in a region with high agricultural activity. For its conformation, a descriptive statistical analysis and a Pearson correlation matrix were performed and the indicators that showed greater variation were identified using a Principal Components Analysis (PCA). A sensitivity analysis was carried out and the most sensible soil indicators of SQI were identified. This statistical procedure was also used to specify the weights of the indicators in SQI. The variables resulting from the multiparametric statistical analysis were pH, organic matter, sodium, calcium, iron, zinc, cation exchange capacity and electrical conductivity. The robustness of the SQI obtained in this study was demonstrated through simulations carried out by the numerical optimization through simplex method. The Soil Quality Index range obtained (0.54 -0.75) locates Culiacan Valley soils as moderate/high quality.

“…Temperature, moisture, light and pH are known to be the most important environmental factors which influence the infection of plants (Tarr, 1989). Environmental factors modify the transmission of disease pathogen and their effect on host plant by modulating the action of the soil microbial community, and in the process renders a soil disease suppressive or conducive (Etebu and Osborn, 2012;Maude, 1996).…”

Seeds are the means of propagating about 90% of all food crops in the world, and they significantly influence yield potential in crop plants. Moreover, seeds are adversely affected by a number of factors such as postharvest and storage disease pathogens and unfavourable environmental conditions. Seed-borne pathogens represent a major threat to crop establishment and yield. Exposure of seeds to disease pathogens and other adverse conditions disrupts their normal physiology and metabolism which ultimately affects productivity. It is therefore imperative to promptly diagnose, treat, prevent and control seed related diseases. As with every other sphere of scientific studies, seed pathology has evolved tremendously over time; hence in this paper the development and emerging perspectives of this all important discipline was reviewed. Pathogen exclusion by detection and elimination of infested seed lots is required for disease management but traditional and conventional measures such as visual examination, use of media culture and serology are inadequate to detect pathogens associated with seed. In contrast, Nucleic acid-based molecular tools, such as the polymerase chain reaction (PCR) have emerged as faster and more reliable means for detecting and quantifying pathogens in seeds than conventional techniques.
