Management data by land class were compared with information from the 2013-2014 harvest provided by the Emiliano Zapata sugar mill, and with leaflets produced for farmers by government institutions. Three types of land were recognized and in order of importance are: Black Clay with Caliche, Black Clay and Brown Clay. The lands were similarly managed in terms of the use of oxen for planting and furrowing, water management, pest control and the use of fertilizers. However, to solve specific problems, different strategies are applied, such as the use of "sacuales" in water conduction, and fertilization with manure or algae accumulated in the channels. Four varieties were identified, which are grown for several cycles. The study verified that the land classes are related to sugarcane yield. There are differences between what the producer does and the technological recommendations of official institutions.

En contraste, el conocimiento tradicional campesino de suelos proporciona informacion que permite conocer la distribucion y el manejo agronomico de los suelos en areas mayores. El objetivo fue determinar la tasa de descomposicion de las raices EnglishMost studies in Mexico on the decomposition of crop roots are carried out on small surfaces and under controlled conditions; this fact limits the regional information. In contrast, local soil knowledge provides information that allows to know the distribution and agronomic management of soil in larger areas. The objective was to determine the rate of decomposition of maize roots Land classes were determined through field trips with farmers work, and the plots were selected through interviews with local producers. The rate of decomposition was obtained from in- growth cores installed in the plots. In addition, bulk soil samples were taken to determine their edaphic properties and their soil classification. Six treatments (plots) were selected in three land classes (clayey black, BN, clayey brown, BP, and clayey with white Tepetate, BB) and two agronomic managements (monoculture and crop rotation). Experimental design was completely randomized, and data were analyzed with ANOVA and Tukey test to compare means. Vertisols and Inceptisols (Soil Taxonomy) or Vertisols and Regosols (WRB) occur in the study area. The local producers recognize three speeds of decomposition based on the presence or absence of fine and thick roots, which matched the values calculated in the in-growth cores in the field. The highest mortality rate in decreasing order was in BN (0.047), BB (0.024) and BP (0.011) with irrigation and in BP (0.001) in rainfed conditions. The interaction between local and technical soil knowledge allowed identifying and calculate speeds and rates of decomposition of roots with different crop management.

Nonetheless, the irrigation district mostly stored sewage, and all of the dredged saline lacustrine material was placed on parcels adjacent to the lake burying the original soils. Since then, the farmers have significantly influenced the formation of soil on their lands through wastewater managements. The objectives were to establish the influence of management practices on soil properties, and to determine how the addition of lacustrine sediment, wastewater and amendments are reflected in both local and scientific soil classification. A soil survey was carried out taking into account the local soil knowledge, and soil management and irrigation practices information were obtained through interviews. Also physical and chemical analyses were conducted. The main contributions of farmers to the reclamation of saline soil with low agricultural productivity include the use of wastewater, the use of differing irrigation frequencies with various crops and materials added to existing soil, and the appropriate combination of amendments (manure and soils). These soil management's strategies have strongly modified the soil properties which are now expressed as different anthropogenic horizons (hydragric, terric, and hortic). They are now classified as Anthrosols. This case study shows how human beings are able to adapt to degraded environments and to produce knowledge and strategies for transforming their surrounding landscape.

The first greenhouse experiment used lisianthus (Eustoma grandiflorum) and included organic (coconut fiber, Cf; and peat moss, Pm) and inorganic (pumice, P; and Perlite, Pe) materials, with varying particle size (1-2 and 2-3.36 mm), using the same organic:inorganic ratio (60:40 v/v), and using bulk material as blank tests. The second experiment used lettuce (Lactuca sativa), with one particle size, but with varying ratios (100 Cf, 75:25, 50:50, 25:75, 100 P v/v) of Cf:P mixtures. Thin sections were prepared from the mixtures of both experiments, to describe sorted degree, distribution patterns and porosity (macro and micro). Furthermore, the water release curve was determined (air capacity, AC; easily available water, EAW) for each treatment in both experiments. In lisianthus, it was observed that using a single particle size Cf:P (1-2 or 2-3.36 mm) renders higher yields, because of the loose packing particles, well sorted material and macro-and micropores, resulting in sufficient EAW (36%) and AC (33%). In contrast, the worst effects were in bulk peat moss, because of the poor sorted, close packing particles, and high micropores content (95%) resulting in a low AC (12%) and EAW (49%), overall. Regarding lettuce, the best ratio resulted in Cf:P 75:25 v/v compared to other ratios, because particles presented a banded distribution pattern generating an heterogeneous porous system (vughs, fissures, and simple and compound packing voids). We conclude micromorphology helps to a better understanding of physical properties of mixtures, and to identify which features for growing materials may improve or restrict lisianthus and lettuce development.

Valenciana) was studied by using a complete randomized 2 x 2 x 7 factorial design with six replicates per treatment. Inoculation of Glomus Zac19 significantly enhanced growth and nutritional status (NPK) of alfalfa, particularly in silt soil. A synergistic effect was observed between Zac19 and the rhizobacteria H. alvei P25 and P27, P. aeruginosa 11PS, and E. cloacae S3DER. Bacteria showed effect variations when they were inoculated alone or in combination with Zac19. Nitrogen content was synergistically enhanced due to the inoculation of Zac19 with P. aeruginosa 11PS and H. alvei P25, whereas P and K content was improved by the dual inoculation of Zac19 with P. aeruginosa 11PS, H. alvei P25 and P27, or B. cepacia P13. Soil type was a significant factor in the behavior and in the expression of beneficial effects to the plant through the inoculation of the rhizobacteria and the arbuscular mycorrhizal consortium Zac19. The rhizobacteria P. aeruginosa 11PS, H. alvei S1AS, P25, and P27 have potential utilization as growth promoting agents of alfalfa.

En este trabajo se determinaron cuáles son los factores de formación que influyen en el tipo y propiedades del suelo en la cuenca rancho Dolores en la región mixteca en el estado de Oaxaca. Se realizó un análisis de componentes principales y una clasif icación no supervisada para la delimitación de unidades de suelo, en las que se realizaron muestreos y análisis de laboratorio de algunas propiedades físicas y químicas. Los factores de formación que explicaron la variabilidad de los suelos de la cuenca fueron: pendiente, índice de posición topográf ica, material parental y uso del suelo. Se delimitaron cinco unidades de suelos con su distribución espacial en la cuenca y se asociaron con sus propiedades de textura, dens...

Para su aplicación se requiere contar con un mapa de suelos, ya que los objetos a clasificar son unidades cartográficas, reagrupando aquellas que resultan semejantes. En México se cuenta con mapas de suelos, escala 1:50 000, elaborados por el Instituto Nacional de Estadística, Geografía e Informática (INEGI), considerados como la información edáfica más detallada del país, que podría utilizarse como mapa base para la aplicación de las clasificaciones técnicas. Sin embargo, su calidad ha sido cuestionada, por lo que se ha propuesto sustituirlos con otros mapas y, además, las clasificaciones técnicas que se usan no se han elaborado en el país y requieren ser evaluadas. El objetivo de la presente investigación fue utilizar al conocimiento local sobre tierras como un marco de referencia para la aplicación y evaluación de dos clasificaciones técnicas de suelos, la de Capacidad-Fertilidad...
