In this paper, we consider the effect of increasing the area of agricultural land under organic practises. We assumed that organic agriculture does not have effective means of pathogen control. We model pathogen dispersal with a diffusive logistic equation in which the growth/death rate is spatially heterogeneous. We find that if the ratio of the organic plots to conventional plots is below a c...

Multifunctional agriculture (MFA) has emerged as a key concept in science and politics with respect to the future of agriculture and rural development in the recent decade. Overall, MFA implies that in addition to their main function in production and support of rural livelihood, the agricultural activities have some other advantages for the environment including the conservation of water and s...

the major purpose of this study was to examine the advantages and implications of biogastechnology in the agriculture sector. biogas is one of many biomass energy sources, which includeanything that was once alive and that can generate energy (except for fossil fuels, which are notrenewable). to talk of biogas is to talk of agriculture, since biogas generation starts withagricultural waste prod...

The paper is centered on the concept of conservation agriculture (CA), which defined as a sustainable cultivation system for future. Conservation (CA) farming that promotes minimal soil disturbance, permanent cover, and crop rotations to maintain health productivity. This approach focuses maximizing natural resources, reducing inputs, improving efficiency nutrient use. CA practices have been fo...

Arkansas agriculture teachers (N=259) were surveyed to obtain information needed by a planning committee studying the issue of science credit for agriculture. Objectives were to determine: (a) the level of support for granting science credit for agriculture; (b) teachers' support for methods of granting science credit for agriculture for agriculture; (c) teachers' support for methods of certify...

Following rapid expansion of huge Agriculture information body on the Web, the efficient Agriculture information gathering on specified top becomes more and more important in search engine research. Through the statement of the developing trend of search engine and sharing agriculture information resource, this paper discusses the necessity of building search engine for agriculture information....

This paper describes the scale and nature of agricultural production in urban, suburban and peri-urban zones of Mexico City and how these have adapted to the changing demands from urban populations for food, wood and recreation. It also demonstrates how agricultural producers have successfully adapted their products and their production methods, including building on traditional production syst...

Agricultural information technology, especially virtual reality(VR) technology, will act the important roles in agricultural modernization and realm. Computer science and IT are both playing important roles in the development of agriculture and rural areas of the world. Combining agriculture science with IT and VR, the virtual agriculture technology explored new ways of studying and applying ag...
