TL;DR: This paper reviews the different methods of measurement of soil aggregate stability used in the literature, paying attention to the conditions of sample collection in the field and sample preparation and treatmen's conditions.
Abstract: Soil aggregate stability is a crucial soil property affecting soil sustainability and crop production A broad outline of the processes and agents of aggregate formation and aggregate stabilization are presented and discussed in this review Aggregate stability is difficult to quantify and interpret The aim of aggregate stability tests is to give a reliable description and ranking of the behavior of soils under the effect of water, wind and management Numerous methods have been used to determine aggregate stability with varying success The different methodologies complicate the comparison among aggregate stability data It is also difficult to obtain a consistent correlation between aggregate stability and other important soil properties such as soil erodibility or crusting potential This paper reviews the different methods of measurement of soil aggregate stability used in the literature, paying attention to the conditions of sample collection in the field and sample preparation and treatmen

TL;DR: In this article, the authors define agroecology as the ecology of food systems and provide a framework that will guide research, education, and action in the multiple and interacting facets of an increasingly complex global agriculture and food system.
Abstract: We present a compelling rationale for defining agroecology as the ecology of food systems. Our purpose is to provide a framework that will guide research, education, and action in the multiple and interacting facets of an increasingly complex global agriculture and food system. To accomplish such goals, it is essential to build bridges and connections among and beyond our disciplines in production agriculture, as well as beyond the farm gate into the rural landscape and community. Fields of sociology, anthropology, environmental sciences, ethics, and economics are crucial to the mix. They provide additional vantage points from which we can view the food system anew, as well as insights on how to establish valuation criteria beyond neoclassical economics. Examples from Mexico, California, and the Nordic Region are used to illustrate the successful implementation of this educational strategy in universities. Design of individual farms using principles of ecology is expanded to the levels of landsca...

TL;DR: In this paper, a conceptual framework for assessing strategies to support the transition from conventional to sustainable agriculture is described, and examples from farming and institutional settings are provided, with a focus on sustainability.

TL;DR: The use of biostimulant compounds in forestry and agriculture offers significant opportuni for farmers, according to findings from current university researc! and field trials as discussed by the authors, improving root and shoot growth, better stress resistance, better root growth potential, and reduction in nitrogen levels of fertilization are some of the possibilities that these compounds connote to sustainable agriculture.

TL;DR: The purpose of indicators is to simplify the system so as to make this reality accessible to the users, in the form of a diagnostic or decision aid tool, and a procedure for developing such indicators in 7 stages is proposed.
Abstract: Real life is often too complex to be understood by means of simple measurements or simulations by models. The purpose of indicators is to simplify the system so as to make this reality accessible to the users, in the form of a diagnostic or decision aid tool. These indicators represent a compromise between the scientific knowledge of the moment, the need to be concise, simplicity of use, and the availability of data. A procedure for developing such indicators in 7 stages is proposed. These are always defined according to an objective. They are either measured, estimated, or calculated by aggregation of data. Their values are assessed relative to a reference. We proposed to evaluate their relevance by a “probability test.” The validation of indicators, i.e., the fact that they fulfil the objective for which they were intended, is done through a “usefulness test” by surveys of end-users. Their scientific value stems from the rigour of the procedure and the degree of consensus which is established a...
