agricultura de reghydroculture Growing plants without soil but in sand or vermiculite or other granular material, using a liquid solution of nutrients to feed them
agricultura de rompuda i artigaslash and burn culture A traditional farming system that has been used by generations of farmers in tropical forests and the savannah of north and east Africa. It is known to be an ecologically sound form of cultivation, and because the soil is poor in tropical rain forests it is a sustainable method of farming. It is still practised today, primarily in the developing countries. Small areas of bush or forests are cleared and the smaller trees burned. This unlocks the nutrients in the vegetation and gives the soil fertilizer that is easily taken up by plants. A few years later the soil is degraded and the farmer moves on to do the same at another site. The original ground is left fallow for anything up to 20 years so that the forest can regenerate. With the growth in population and in the subsequent need for more farming land to produce food, the method is increasingly being used today to clear large areas of tropical forests for cattle ranching, and in most cases the ground is not left fallow for long enough and, with modern mechanized farming systems, not enough tree stumps or suitable habitats for plant life are left to start the regeneration process
agricultura de secàdry farming A system of extensive agriculture allowing the production of crops without irrigation in areas of limited rainfall. Dry farming involves conserving soil moisture through mulching, frequent fallowing, maintenance of a fine tilth by cross-ploughing, repeated working of the soil after rainfall and removal of any weeds that would take up some of the moisture
agricultura intensivaintensive farming Farming in which as much use is made of the land as possible by growing crops close together or by growing several crops in a year or by using large amounts of fertilizers
impacte ambiental de l'agriculturaenvironmental impact of agriculture Agricultural activities have significant impacts on water quality, including increases in stream sedimentation from erosion, and increases in nutrients, pesticides, and salt concentrations in runoff. In certain regions, the misuse of pesticides has led to the development of pesticide-resistant strains of pests, destroyed natural predators, killed local wildlife, and contaminated human water supplies. Improper application of fertilizers has changed the types of vegetation and fish types inhabiting nearby waterways and rivers
legislació ambiental sobre agriculturaenvironmental legislation on agriculture A binding rule or body of rules prescribed by a government to regulate any aspect of farm and livestock production that poses a threat to ecological integrity and human health, especially the use of pesticides, fertilizers and land
