Soil conservation is the only known way to protect the productive land. In country like Ethiopia, where droughts and floods cause food scarcity problem, soil and water conservation not only increases crop yield, but also prevents further deterioration of land. Soil and water conservation preserve soil moisture and drain water sustainably to avoid soil erosion and depletion of soil nutrients. So...
The maintenance of low-intensity farming is important for the conservation of habitats and species and is a particular issue in Europe as areas under extensive farming regimes continue to diminish. Current proposals for agricultural reform in Europe are seeking to retain and encourage extensive farming partly by seeking to redirect farm workers into non-farm activities such as leisure activitie...
energy consumption in iran is a subject of debate. some may think that oil is cheap in iran and thus no need for this kind of research. this simple minding is erroneous first because iran subsidizes billion dollars each year for the imported diesel fuel specially for agricultural use and second because energy studies reveal the degree of professionally using the technology. we can easily find t...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
This article presents suggestions toward safer animal handling utilizing the results of a qualitative study of women dairy farmers in Finland. A major proportion of injuries (43%) occur in livestock-related work in Finnish agriculture. An even greater proportion of women's farm injuries (77%) is related to animals. We investigated the working conditions often women dairy farmers. Data were coll...

Events of the 1990s seem to have given the small farm a new lease on life. Organic agriculture offers a means of producing considerable profitability on very small areas even if many small farmers are of necessity only part-time farmers. Opportunities off the farm, however, have enabled owners of small parcels to farm them profitably, or at least sustainably. Urban agriculture is now a respecte...
Modern wind farms comprised of horizontal-axis wind turbines (HAWTs) require significant land resources to separate each wind turbine from the adjacent turbine wakes. This aerodynamic constraint limits the amount of power that can be extracted from a given wind farm footprint. The resulting inefficiency of HAWT farms is currently compensated by using taller wind turbines to access greater wind ...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
