Agricultural practices affect the physical, chemical, and biological properties of soil in agroecosystems. This study evaluated the impact of food production strategies on the rhizosphere microbial communities in the Yaqui Valley, Mexico, on key crops (Medicago sativa, Brassica oleracea, Asparagus officinalis, Phaseolus vulgaris, Citrus sinensis, Z...

Objective: To analyze the situation experienced by the agricultural organizations in the Yaqui Valley in relation to the way they generate knowledge and their capacity for innovation in health contingency. Methodology: Through qualitative research using interview guides with various farmers in the Yaqui Valley. Results: It was found that the agricu...

Journal of environmental science and health. Part. B, Pesticides, food contaminants, and agricultural wastes
A pesticide characterization is presented for two highly technified valleys in northwest Mexico: Culiacan Valley (CV) in Sinaloa and Yaqui Valley (YV) in Sonora. Approximately 250,000 kg of active ingredients are used every year, half of which are considered highly hazardous pesticides. Legacy pesticides are still present in the soils of these vall...

Nutrient Cycling in Agroecosystems
Searching for sustainable cropping systems has often focused on the optimization of system sustainability, yield or ideally both. It is important to also include wheat quality characteristics like grain protein concentration (GPC) and bread-making quality (loaf volume). The effect of placement and timing of nitrogen (N) fertilizer on performance an...

Abstract: In this first study on aeromycota from the state of Sonora, Mexico, the airborne fungal diversity of Ciudad Obregón was determined and quantified with a Hirst-type sampler according to internationally accepted methods (Spanish Aerobiology Network). Spearman statistical correlations between the dominant fungal taxa and several meteorologic...

Abstract: Women studies had been a limited subject, particularly in the Sonoran research. It is evidently the lacking of historical approaches, but it is worst in the rural area, because the analysis of colonization of Yaqui Valley is based in the distribution of land as the main subject. This article recovers the characteristics of everyday life o...

There is a clear need to develop conservation agriculture technologies appropriate for surface irrigated conditions, and the adoption by small-scale farmers. The objective of this paper is to evaluate the effect on soil quality of five different tillage-crop residue management systems (conventionally tilled raised beds [CTB] with residue incorporat...

Nutrient Cycling in Agroecosystems
An improved version of an ecosystem nitrogen cycling model (NLOSS) is described, tested, and used to analyze nitrogen cycling in the Yaqui Valley, Sonora, Mexico. In addition to previously described modules in NLOSS that simulate soil water and solute fluxes, soil evaporation, soil energy balance, and denitrification, modules were added to estimate...

In several human populations, the age at which female breast development begins is reported to have declined over the last five decades. Much debate has occurred over whether this reported decline has actually occurred and what factors contribute to it. However, geographical patterns reflecting earlier developmental onset in some human populations ...

Irrigation and Drainage Systems
Components of a satellite-based system for estimating the crop water requirements of irrigated vegetation have been combined, applied, and tested against field data in the Yaqui Valley, northwest Mexico. Frequent satellite observations have the potential to provide snap shots of cloud variability at the high spatial and temporal resolutions that ar...
