This book was released on 2020-08-13 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: El país está enfrentado un tema tan crítico como la apertura económica -tratados recién firmados como el TLC con Estados Unidos- obligan a los gremios del sector productivo a ser más competitivos si quieren continuar en el mercado. Uno de los elementos para mejorar este aspecto es la eficiencia en el uso de los recursos (fertilizantes, riegos, manejo sostenible del medio ambiente, etc.). La toma de decisiones es un paso difícil en cualquier empresa. En la empresa agropecuaria intervienen muchos elementos, componentes y variables que es necesario conocer a la hora de decidir. Como el momento de las decisiones y los resultados están alejados en el tiempo, los problemas se manifiestan cuando suele ser tarde para resolverlos. Así, para tomar buenas decisiones es fundamental una correcta información previa. Un análisis equivocado lleva siempre a un mal resultado; cuando los márgenes de ganancia de la actividad agropecuaria se reducen, el costo del error puede ser crítico. Las buenas decisiones solo pueden ser resultado de un correcto análisis de las variables y esto solo puede hacerse con buena información.

Available in PDF, EPUB and Kindle. Book excerpt: El suelo, como soporte físico y fuente de elementos nutritivos constituye un elemento fundamental para el correcto desarrollo y la buena producción de cualquier especie vegetal. El conocimiento de los niveles de nutrientes en el suelo, la composición físico-química del mismo, los niveles de extracción de los distintos cultivos y el estado nutricional de éstos es la fase inicial de cualquier intento de mejora cuantitatva y cualitativa de la producción, así como el elemento básico para lograr un uso racional y equilibrado de los fertilizantes, que permitirá evitar tanto el despilfarro económico como las posibles consecuencias respecto a la contaminación de suelos y aguas. El presente trabajo tiene como objetivo facilitar a los técnicos y agricultures una información básica, que les permita realizar una correcta toma de muestras de la tierra y una adecuada interpretación de los resultados analíticos, que haga posible el conocimiento del estado nutricional del suelo en función de las necesidades de las plantas así como un abonado racional y científico.

This book was released on 2021-09-08 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in particular Goal 15, “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification and halt and reverse land degradation and halt biodiversity loss” with the SOC stock being explicitly cited in Indicator 15.3.1. This technical manual is the first attempt to gather, in a standardized format, the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks and constraints. This manual presents different sustainable soil management (SSM) practices at different scales and in different contexts, supported by case studies that have been shown with quantitative data to have a positive effect on SOC stocks and successful experiences of SOC sequestration in practical field applications. Volume 4 includes 51 case studies dealing with cropland, grassland, integrated systems and farming approaches.
Download or read book Micronutrients in Tropical Food Crop Production written by Paul L.G. Vlek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mission of the International Fertilizer Development Center is to increase food production through the improvement of fertilizers and fertilizer practices for the developing countries with special emphasis on tropical and subtropical agriculture. The principal aim is to ensure that fertilizer technology is not a limiting factor to food production in those regions. Although the full extent to which deficiency of micronutrients hampers food production is yet un known, there is ample evidence that problem areas exist and more will be identified as crop production is intensified and marginal lands are exploited. Therefore, it seems fully appropriate at this time that IFDC, as an international organization, take a leadership role in developing micronutrient fertilizer technology appropriate for the tropics and subtropics. The gravity of micronutrient deficiency as a limiting factor to crop pro duction varies from crop to crop and from soil to soil. The effects may range from slight yield reductions to complete crop failure. While the economic impact of omitting micronutrients in seriously affected areas (e.g., Zn in Brazilian Cerrado) is convincing, it is difficult to estimate the yearly loss in crop production due to unsuspected micronutrient deficiency. Active soil and crop testing programs in regions with advanced agricultural systems are aimed at recognizing micronutrients as a limiting plant nutrient in time to allow corrective measures and prevent yield loss. Successful micronutrient monitoring systems are generally limited to developed economies or to developing economies producing export cash crops.
