Overall, a higher biodiversity will reduce the risk of pest outbreaks, whereas it will also benefit the biological processes that are needed for agricultural production and create diversification of income and risks see section on Agricultural Biodiversity.
The only people who think organic farming can feed the world are delusional hippies, hysterical moms, and self-righteous organic farmers. Store and use agrochemicals according to legal requirements, e. Inspired by a field trip to a nearby organic farm where the farmer reported that he raised an amazing 27 tons of vegetables on six-tenths of a hectare in a relatively short growing season, a team of scientists from the University of Michigan tried to estimate how much food could be raised following a global shift to organic farming.
Other factors include levels of natural enemies, plant health and ability to compensate for damage, other investment opportunities, personal health, and weather are involved in the decision making process.
Lethal dosages are usually given in both oral through the mouth and dermal exposure to skin levels. The world would be able to sustain high levels of biodiversity much better if we could change agriculture on a large scale. If five farmers eliminate half their use of chemicals, the effect on the environment will be two and one-half times as great as if one farmer goes totally organic.
Researchers have suggested that the conversion of 10, small- to medium-sized farms to organic production would store carbon in the soil equivalent to taking 1, cars off the road.
For other crops, larger fragments of natural habitat e. There is good reason to believe that a global conversion to organic farming would not proceed as seamlessly as plugging some yield ratios into a spreadsheet.
Whereas this is one larger component of monitoring, at farm level the farmers should also be aware of what different pests and beneficial organisms look like and what if there is any the tolerable level is in the field.
These include family corporations 4. Access to certified seeds will improve the uptake of farmers of higher-yielding varieties which can withstand stress and thus decrease environmental problems that are caused by use of pesticides see section on Seeds and Plant Genetic Resources. Use resistant cultivars and varieties, crop sequences, associations, and cultural practices that minimize the pressure and maximize biological prevention of pests and diseases.
Exact measures will depend on the crop and landscape configuration, which means that monitoring is needed at ecosystem, or higher, level. The small farmers and indigenous communities of the Global South, with the help of scientists and NGOs, can continue to create and guard biological and genetic diversity that has enriched the food culture of the whole planet.
Eliminate nitrogen fertilizer and many farmers will probably graze cows on their fields to compensate. Given the growing interest in organic farming among consumers, government officials, and agricultural scientists, the researchers wanted to assess whether a large-scale conversion to organic farming in Europe and North America the world's primary food exporting regions would reduce yields, increase world food prices, or worsen hunger in poorer nations that depend on imports, particularly those people living in the Third World's swelling megacities.
Protection and enhancement of important beneficial organisms The configuration of the landscape can help to improve habitat for beneficial organisms for pest control and pollination see section on Pollinator Management.
Again, these are just theoretical assumptions, since a global shift to organic farming could take decades. The risk associated with these biological pest control agents are favourable in comparison with the conventional synthetic chemicals and in some cases they might even be acceptable in organic production systems.
And yields, organic or otherwise, may not improve enough if agriculture in the future is threatened by declining water tables or poor soil maintenance.
Intercropping is advanced management practices of soil fertility status, consisting of cultivating two or more soil fertility status under smallholder farms of semi-arid to exploration of large soil mass compared to monocropping.
Most large-scale industrial farms are monoculture farms, meaning they grow only one type of crop at a time. The Union of Concerned Scientists says this type of farm relies heavily on chemical inputs.

Today, Cruse dismisses strip intercropping for the average grower for “reasons of scale. It restricts the number of acres you can farm,” he says. “Growers these days focus on large expanses of land, rather than adding more bushels per-acre on smaller tracts.” Not so, says acre Fairbank, IA, farmer and retired John Deere Engineer Ben Witte.
Small farms are more productive and resource conserving than large-scale monocultures Although the conventional wisdom is that small family farms are backward and unproductive, research shows that small farms are much more productive than large farms if total output is considered rather than yield from a single crop.
Even small-scale farmers with land sizes farm, because this technique is such a localized, process mainly due to the limited availability of plant residue.Intercropping should large scale farms be
