no cause they dont think they need to practice hg
Emphasis upon high yields versus focus upon optimal health is the difference between intensive farming. Farmers who practice intensive farming look at a field in terms of what crop variety, what fertilizer brand and what herbicide and pesticide treatments will result in products that will cover costs and make profits through maximum marketing and sales. Farmers who practice organic farming must balance expenses and profits but they do so while imitating Mother Nature's cycles and ways of growing healthy animals and crops that will sustain the landscape, the people and themselves.
Well, they aren't using harmful chemicals.
Do no environmental harm is the organic farming rule. Organic farmers therefore refrain from chemical, genetically modified, non-local, and off-site inputs. Organic farming requires attention to the health of the soil and of its soil food web and the coordination of well-being with weather and wildlife.
Typically farmers choose inorganic or conventional farming because 1) that is what they are accustomed to, and 2) cost efficiency. To be considered organic not only do you have to practice organic farming but you also have to buy a permit or license that costs quiet a bit of money. Also man made pesticides are much cheaper than the organic alternatives. Many farms are passed along through generations and have been taught by their parents or grandparents. This makes changing the identity or practices of your farm difficult because this is the way you were taught and how it has always been.
Ladybugs are great. They eat insects that farmers consider to be pests, like aphids, and don't harm plants themselves. So if you have enough ladybugs and the right climate, you could eliminate your need for pesticides on some plants, which aids organic farming significantly. Unfortunately ladybugs cost a lot more than pesticide, so it's not common practice in commercial farming.
Because they don't think they can make enough money that way.
No. It takes several years in which you have to practice organic farming (which costs more) and sell your produce as regular crops with regular prices. It also means learning new ways of dealing with problems and a change in mind frame thing much more long term slow processes rather then immediate results. It also means changing your market and clientele. Quite a few challenges. An alternate answer: Switching from modern farming (i.e. "chemical" farming) to organic farming doesn't necessarily mean more expenses for the farmer. It does entail different methodology and practices, however. "Easy" is a relative term. For some farmers, the switch would never be easy, for others, there is no other way to farm. In terms of a sustainable planet, many farmers feel that organic is the only way to go. After all, until the "modern" era, with chemicals, organic was the way farmers raised crops for thousands of years. response to alternate answer: organic farming is a far cry from sustainable farming in fact for each acre of organic farming one needs 5 acres of non organic farming to produce enough compost for it to fertilize the field. if you were to gather all organic waste in the world and compost the whole lot and spread it evenly all over agricultural areas you'll get about a sixth of the minimum amount needed to grow organicly. additionnaly organic farming requires more labor and produces less product so if you want to change to organic farming and still sustain the current human population you need to cut down more rain forests and nature reserves to have enough agricultural area to grow food. there are many many many reasons NOT to grow organic especially from an envirumentally friendly approach. It also will help if you learn about organic farming as a chemical to change quickly
Organic cultivation promotes better health and environment, it's one of the best good food habits to follow. The ill effects of chemicals in farming techniques have affected the cultivator. Natural farming techniques help in improving soil fertility and better yield. Intensive farming can deplete nutrients from the soil, therefore organic farming is useful. Organic farming is cost effective and less risky. Unlike the non organic, organic farming doesn't require multiple objectives.

organic farmers plan carefully far in advance to ensure appropriate feed supplies and access. Organic livestock must be maintained on land that is free from any chemical infiltration
That chemicals, genetic modification and synthetics are disallowed is the reason why organic farmers do not use herbicides. The equivalent controls in organic farming receive the label botanicals if the treatments come from plants, such as pyrethrin from Chrysanthemum cinerariifolium. Much of the plant pest control in organic farming will be achieved by eliminating the stresses that encourage pathogens and pests through respect for plant-specific air, heat, light, moisture and nutrient needs.
Organic farming can be done anywhere in the world.
