On a world-wide basis, the number of university courses in agricultural science and related disciplines such as agricultural economics and farm manangement increased dramatically in the 1950 to 1990 period. One of the most important factors influencing this development was the perceived need to enlist the assistance of modem science to solve the world food problem. That is, for the last four decades, agricultural education at the tertiary level has been primarily orientated to increasing food production. Consequently, a large proportion of the human capital (researchers) created by these educa...

Scale operation of agricultural land is necessary for agricultural modernization. To achieve scale operation, Japan relaxed quantity and rent restrictions on agricultural land, and tried to facilitate the development of efficient and stable agricultural producers. However, these policies have not essentially changed the agricultural operation pattern featured by small-scale households, considerably deviating the facts from the ideal. Rethinking the causes of this deviation is highly implicative for China's efforts in the scale operation of agricultural land.

The rational use of water is essentual as it is a finite resource. Consequerntly, studies of methids that minimize water use water are essential. As a result, agricultural hydrogels have been extensively tested in as a means of promoting agriculture improvements because of their waterand nutriente-retention characteristics. However, even though hydrogels are used in several sectors of Brazilian agriculture, there are still very few studies on their applications, the best methods and the quantities to be used. Consequently, there is a need for research into the applicability of this technology ...

- Historically, agriculture has been a large contributor to the global green house gas emissions due to the use of fossil fuel-powered machinery during the production cycle.

The objective of this work is to display, in general lines, a boarding regarding the municipal planning directed toward the dynamics of the relations between the environment, the transport and the socioeconomic in the urban centers. It presents an argument on the viability of the induction of urban models of agricultural production as a strategically program for harmonizati...

Si Xénophon dans l’Économique et Platon dans les Lois prônent sans réserve l’intégration politique de l’agriculture et des agriculteurs, le cas d’Aristote dans les Politiques, c’est notre thèse, est différent. S’il fait de l’agriculture l’activité économique principale de toute cité juste pour des raisons à la fois empiriques et métaphysiques, la question de savoir qui doit l’exercer reste problématique : tandis que l’idéal serait à ses yeux que des esclaves ou des populations étrangères s’en chargent afin que les hommes libres se consacrent exclusivement aux affaires politiques, la réalité du...

The industrialization of agriculture has caused the reduction of profits for agricultural activities, environmental disasters, exclusion of the rural inhabitant and the production of food with residues harmful to human health. Agroecology banishes the use of synthetic chemical products and proposes safekeeping the environment from aggressions, producing food without contaminating elements, reducing the costs of production, increasing the offer of work and thus avoiding the rural exodus. This proposal increases the chances of rendering sustainable the agricultural system and it is the most suit...

Cato s second century BCE De Agricultura is our earliest complete Latin prose text, recommends farming for its security and profitability, and advises on management of labor and resources.

Ce chapitre analyse a grands traits les structures generales de l'organisation de l'agriculture et des agriculteurs dans quelques grandes regions du monde. L'organisation de l'agriculture est entendue comme l'ensemble des formes institutionnelles qui environnent et structurent l'activite des agriculteurs et la relient au reste de la societe: il s'agit par exemple des structures foncieres (taille des exploitations), du type de marches (specialises, concentres), de la facon dont la recherche et les services agricoles sont organises... Les organisations des agriculteurs renvoient a toutes les for...

L'etat des lieux sur la transition postsocialiste des agricultures apres 7 ans revele une forte differenciation regionale et surtout nationale de trajectoires de sortie du collectivisme. Les deux heritages du collectivisme et des structures agraires anterieures a la Seconde Guerre interviennent de facon complexe. L'importance d'un ensemble heterogene de neocooperateurs face aux divers paysans et entrepreneurs individuels se rapprochant des modeles occidentaux souligne la dimension "d'entre-deux" de cette partie de l'Europe agraire.

[fre] Du fait de la baisse constante du nombre d'exploitations agricoles et du nombre insuffisant d'enfants d'agriculteurs susceptibles de s'installer, l'installation dite « hors cadre familial » est encouragee. Au travers d'etudes de cas monographiques, l'article a pour objectif de cerner les motivations de ces « nouveaux agriculteurs », de presenter les difficultes specifiques qu'ils rencontrent- en termes de travail comme en termes d'acces au foncier - et d'analyser les strategies qu'ils mettent en œuvre pour contourner ces difficultes. Avec ces exemples, c'est aussi la selectivite et la co...

The recent discoveries of the physiological properties of the brassinosteroids allow regarding as natural substances themselves highly promissory and appropriate for his use in the protection of the plants and increase in the agricultural produce.

Resume. - De nombreuses exploitations agricoles sont aujourd'hui considerees comme «industrielles». L'article denonce remploi abusif de ce qualificatif qui devrait etre reserve a certains cas exceptionnels, et etablit la distinction entre une agriculture «industrielle » (ayant les caracteres de l'industrie) et une agriculture «industrialisee » (qui entretient des rapports etroits avec l'«amont» et l'«aval» industriel, mais reste d'essence familiale).

The agricultural and farm labor history of African Americans extends across more than four centuries, from slavery beginning in the early 17th century to freedom resulting from the Civil War to a small number of independent farm owners by the early 21st century. Prior to the Civil War, slavery primarily served as an agricultural labor system. During the colonial period, only a few free African Americans owned land and farmed independently, but most worked in some fashion as slaves, producing tobacco and rice, tending livestock, and processing food. In 1794, Eli Whitney patented the first effic...

Precision agriculture makes use of RS to macro-control, of GPS to locate precisely ground position and of GIS to store ground information. It precisely establishes various operation, such as the best tillage, application of fertilizer, sowing, irrigation, spurting etc,turns traditional extensive production to intensive production according to space variable data. Precision agriculture not only may utilize fully resources, reduce investment, decrease pollution of the environment and get the most of social and economic efficiency, but also makes farm products, the same as industry, become contro...

The limits of the research are those caused by the absence of linguistic tools specific to the field of GPS. The practical implications of the study are dictated by the purpose of the study...

The objective of this review is to show how biochar (BC) can be obtained and its effects on the physicochemical properties of soils and physiological behavior of cultivated plants. Biochar is a product rich in carbon that comes from the pyrolysis of biomass, generally of vegetable origin. It is obtained by the decomposition of organic matter exposed to temperatures between 200-900 °C in an atmosphere with low oxygen availability (pyrolysis), which can be slow, intermediate or fast. BC can contain varying levels of elements such as: carbon, nitrogen, oxygen, hydrogen, and sulfur. The primary so...

It was possible to identify some risks inherent in agricultural activity and its contribution to the emergence of health problems of workers engaged in agricultural activities and it is fundamental to adopt health promotion and surveillance strategies for this group.

The paper is centered on the concept of conservation agriculture (CA), which is defined as a sustainable cultivation system for the future. Conservation agriculture (CA) is a sustainable farming system that promotes minimal soil disturbance, permanent soil cover, and crop rotations to maintain soil health and productivity. This approach focuses on maximizing natural resources, reducing inputs, and improving the efficiency of nutrient use. CA practices have been found to reduce soil erosion, conserve water, and increase soil organic matter, leading to improved crop yields and reduced greenhouse...

A renewed focus on agriculture’s potential contribution to economic transformation in Africa has resulted in increased attention paid to agricultural mechanization. African agriculture still relies predominantly on human muscle power despite anecdotal evidence on urbanization and rising rural wages, in contrast to other developing regions that have experienced rapid increases in agricultural mechanization during the past few decades. Past state-led mechanization pushes in Africa often failed due to insufficient understanding of the nature of demand for mechanization technologies among farmers ...

In early America, settlers were totally dependent upon their food source. If they produced their own food, they knew how to grow it, where to sell it, and how to process and preserve it so that it remained safe for consumption. If they did not produce their own food, they knew where to find the most reliable source, both in quality and quantity. They knew because their lives depended upon this knowledge. Although most agriculturalists would argue that little has changed in our dependency upon a reliable source of quality food, most would also agree that the vast majority of Americans know very...

Land application of sewage sludge seems justifiable mostly because of its phosphorus content. Depending on the distribution of cattle manure the total Danish supply of phosphorus could be provided by manure and sludge. Or sludge phosphorus could substitute from 30—100% of all imported raw phosphates utilized domestically for agricultural purposes. Increased sludge phosphorus production would require extended waste water treatment. Due to increased costs of imported phosphorus such treatment may actually prove economically sound using well known technology. Furthermore it may reduce eutroficati...
