TL;DR: In this article, the authors evaluate the risks involved when traditional agricultural management practices are applied to different ecological settings while the underlying ecological principles of those practices are not well understood, and suggest that traditional management practices may be ecologically sound when considered within their original ecological context, but may be inappropriate in new ecological settings.

TL;DR: In this paper, a metodologia for abordar la racionalidad ecologica in tres grupos de agricultores horticolas del partido de La Plata, Argentina, was presented.
Abstract: La existencia de una racionalidad ecologica implicita en el manejo de los recursos naturales en agricultores tradicionales ha permitido la sustentabilidad de los agroecosistemas. Comprender la racionalidad ecologica en agricultores con caracteristicas diferentes a la agricultura tradicional, podria contribuir a avanzar hacia una agricultura sustentable. Sin embargo, esto no es sencillo debido a la propia complejidad del termino y la ausencia de metodologia que permita abordarla. En este contexto, se propone y valida una metodologia para abordar la racionalidad ecologica en tres grupos de agricultores horticolas del partido de La Plata, Argentina. La propuesta consta de ocho pasos: 1) definicion del marco conceptual, 2) planteo de hipotesis, 3) definicion de las dimensiones de analisis, 4) definicion de ambitos, categorias y descriptores de analisis, 5) definicion de los indicadores, 6) relevamiento de datos, 7) analisis de resultados, 8) validacion de la hipotesis. La metodologia permitio generar un conjunto de indicadores que fueron sensibles y pertinentes para analizar la racionalidad ecologica. Se observo que los agricultores organicos y los pequenos agricultores, con menor posibilidad de incorporar insumos externos, desarrollan una racionalidad ecologica mas adecuada a la conservacion de los recursos naturales, que los agricultores capitalizados con mayor acceso a la tecnologia.

TL;DR: In this paper, the authors analyze the conocimiento de la racionalidad ecologica (RE) in relation with the capacidad of modificar el ambiente in 3 grupos de agricultores horticolas de La Plata (capitalizados, pequenos, and organicos).
Abstract: Se analizo la racionalidad ecologica (RE) en relacion a la capacidad de modificar el ambiente en 3 grupos de agricultores horticolas de La Plata (capitalizados, pequenos y organicos). La RE se evaluo a traves de las dimensiones Saber y Hacer, para las cuales se construyeron indicadores y se seleccionaron ambitos de evaluacion y categorias de analisis. Se encontro que la capacidad de modificar el ambiente estuvo asociada negativamente con la RE. Los agricultores organicos presentaron una mayor RE seguidos de los pequenos y de los capitalizados. Se concluye que el conocimiento de la RE de los agricultores es una herramienta valiosa para el diseno de estrategias de intervencion por parte de profesionales, instituciones y organismos de extension.

TL;DR: In this article, the balance of nutrientes (N, P, K, Ca, S, S) in the produccion of leche (PL) and carne (PC) was analyzed in the provincia of Buenos Aires.
Abstract: Una produccion agropecuaria sustentable debe ser compatible con la conservacion de los recursos naturales, entre ellos el suelo. Un objetivo necesario es la conservacion de los nutrientes del suelo, lo cual esta influenciado por el modelo de produccion realizado. En Buenos Aires existen escasos estudios que analicen el balance de nutrientes de la produccion de carne y leche bovina, a pesar que ocupa el 54% de su superficie. En parte esto se debe a que se asocia a la ganaderia con la mejora en la fertilidad edafica, aunque esto puede estar enmascarando una disminucion del reservorio de nutrientes. En este trabajo se evaluo el impacto de la produccion de carne y leche en la conservacion de los nutrientes del suelo en la provincia de Buenos Aires. Se analizo el balance de nutrientes (N, P, K, Ca, S) en la produccion de leche (PL) y carne (PC). Se encontro que PL es mas extractiva por hectarea en todos los nutrientes que PC. En ambas actividades el balance de nutrientes fue positivo en N y P y negativo en el resto de los elementos, siendo PC el mayor responsable en los excesos y deficit totales. La fijacion biologica fue la principal entrada en N y la fertilizacion en P. Los excesos de N se observaron en toda la provincia mientras que en P solo en la zona con mayor presencia de tambos e invernada. La sustentabilidad de la ganaderia necesita de la reposicion de K, Ca y S en toda la provincia y de P en buena parte de la misma.

TL;DR: In this paper, a comparative study of two agroecosistemas (vinedos), abordados a traves del enfoque sistemico, is presented.
Abstract: Una agricultura sustentable requiere un abordaje de los sistemas que permita entender tanto los componentes como las interacciones entre estos. En este trabajo se compararon dos agroecosistemas (vinedos), abordados a traves del enfoque sistemico. Se analizaron componentes, interacciones, entradas y salidas a los sistemas; asi como las similitudes y diferencias tanto en el ciclado de la materia organica, como en el flujo de nutrientes. Palabras clave: enfoque sistemico, agroecosistema, sustentabilidad, agroecologia.

TL;DR: In this article, the impact of various management practices on soil loss in vineyards was evaluated in small vineyards located in southwestern Slovakia in the Vrable viticultural district, using the levelling method.
Abstract: Vineyards represent one of the most erosion-prone types of cultivated land. Because of this, cultivation practices are very important in reducing the soil erosion risk in vineyard regions. The aim of this paper was to assess the impact of various management practices on soil loss in vineyards. Effects of tillage, hoeing, rotavating and grass cover were evaluated in small vineyards located in southwestern Slovakia in the Vrable viticultural district. Erosion and deposition rates were estimated using the levelling method. This method is based on an evaluation of variability of the soil surface against vineyard poles measured between the year of pole insertion and the year of measurement. On the basis of the measured data, a WATEM/SEDEM distributed soil erosion model was calibrated, and the total soil loss from the vineyards under different management conditions was estimated. The model shows rather good performance in modelling soil erosion, but at the same time, it shows lower reliability in modelling soil deposition. Downslope tilled vineyards were the most eroded; the erosion in rotavated vineyards is somewhat reduced. The most protective tillage system is hoeing. Considerably lower soil loss was estimated with the use of vegetation cover between vine rows, which is in accordance with agro-environmental schemes supporting use of grass cover as an erosion prevention measure in vineyards.

TL;DR: In this paper, the authors present an overview of existing data and modelling approaches for terroir functional modelling, footprinting and zoning on local and regional scales, focusing on two main areas of recent terro-ir research: (1) using new tools to unravel the biogeochemical cy-cles of both macro- and micronutrients, the biological and chemical signatures of terroirs (i.e. the metagenomic approach and regional fingerprinting); (2) terroIR zoning on different scales: mapping terroires and using remote- and
Abstract: Notions of terroir and their conceptualization through agro-environmental sciences have become popular in many parts of world. Originally developed for wine, terroir now encompasses many other crops in- cluding fruits, vegetables, cheese, olive oil, coffee, cacao and other crops, linking the uniqueness and quality of both beverages and foods to the environment where they are produced, giving the consumer a sense of place. Climate, geology, geomorphology and soil are the main environmental factors which make up the terroir ef- fect on different scales. Often considered immutable culturally, the natural components of terroir are actually a set of processes, which together create a delicate equilibrium and regulation of its effect on products in both space and time. Due to both a greater need to better understand regional-to-site variations in crop production and the growth in spatial analytic technologies, the study of terroir has shifted from a largely descriptive regional science to a more applied, technical research field. Furthermore, the explosion of spatial data availability and sensing technologies has made the within-field scale of study more valuable to the individual grower. The result has been greater adoption of these technologies but also issues associated with both the spatial and temporal scales required for practical applications, as well as the relevant approaches for data synthesis. Moreover, as soil microbial communities are known to be of vital importance for terrestrial processes by driving the major soil geochemical cycles and supporting healthy plant growth, an intensive investigation of the microbial organiza- tion and their function is also required. Our objective is to present an overview of existing data and modelling approaches for terroir functional modelling, footprinting and zoning on local and regional scales. This review will focus on two main areas of recent terroir research: (1) using new tools to unravel the biogeochemical cy- cles of both macro- and micronutrients, the biological and chemical signatures of terroirs (i.e. the metagenomic approach and regional fingerprinting); (2) terroir zoning on different scales: mapping terroirs and using remote- and proxy-sensing technologies to monitor soil quality and manage the crop system for better food quality. Both implementations of terroir chemical and biological footprinting and geospatial technologies are promising for the management of terroir units, particularly the remote and proxy data in conjunction with spatial statistics. Indeed, the managed zones will be updatable and the effects of viticultural and/or soil management practices might be easier to control. The prospect of facilitated terroir spatial monitoring makes it possible to address another great challenge in the years to come: the issue of terroir sustainability and the construction of efficient soil/viticultural management strategies that can be assessed and applied across numerous scales.
