What is organic farming What are its limitations?
Limitation: Organic manure is not abundantly available and on plant nutrient basis it may be more expensive than chemical fertilizers if organic inputs are purchased. Production in organic farming declines especially during first few years, so the farmer should be given premium prices for organic produce.
What is organic farming explain its benefits and limitations?
Benefits of organic farming: (i) In organic farming synthetic chemicals, (petroleum based) are not required. (ii) Organic crops contain more secondary metabolites than the conventionally grown plants. (iv) Organic farming yields on average around 20% less produce than does conventional farming.
What is organic farming and examples?
Definition of organic farming Unprocessed products: vegetables, cereals, fruits, cotton, flowers, animals, eggs or milk; Processed products for human consumption: cheese, bread or instantaneous meals; Food for animals like organic soy cakes; Materials for vegetative reproduction and seeds.
What is organic farming in easy words?
In other words, organic farming is a farming method that involves growing and nurturing crops without the use of synthetic based fertilizers and pesticides. It relies on ecologically balanced agricultural principles like crop rotation, green manure, organic waste, biological pest control, mineral and rock additives.
Which manner is used in organic farming?
The important concentrated organic manures are oilcakes, blood meal, fish manure etc. These are also known as organic nitrogen fertilizer. Before their organic nitrogen is used by the crops, it is converted through bacterial action into readily usable ammoniacal nitrogen and nitrate nitrogen.
What chemicals are used in organic farming?
Time For The Truth: Yes, Organic Farming Uses Pesticides 889/2008. It includes materials such as composts and manures, but also inputs or pesticides such as aluminum-calcium phosphate, magnesium sulfate, sodium chloride, calcium polysulfide, copper sulfate, and many others that can be used.
What is the best natural insecticide?

- Soap Sprays.
- Diatomaceous Earth.
- Milky Spore.
- Iron Phosphate.
- Neem Oil.
- Pyrethrum.
Can hydrogen peroxide be used in organic farming?
Organic farming is characterized by lower yield stability as compared to conventional farming methods. Hydrogen peroxide (3%) when sprayed on crops can control soft tissue pests such as aphids, red spider mites and fungal diseases like powdery mildew.
Does organic farming use crop rotation?
Crop rotation, planting a different crop on a particular piece of land each growing season, is required in organic crop production because it is such a useful tool in preventing soil dis- eases, insect pests, weed problems, and for building healthy soils.
What are the benefits of crop rotation in organic farming?
Crop rotation helps control the erosion of soil from water and wind by improving the soil structure and reducing the amount of soil that is exposed to water and wind. Crop rotation also supports reduced or no-till farming, which ensures even better protection against erosion.
Which is a reason that organic farming is more expensive than conventional farming?
If the demand for organic food continues to grow, the supply could be scaled up, and organic food could subsequently go down in price (your basic supply and demand). Another reason organic food costs more is because the production process is more expensive.
What are the three advantages of crop rotation?
Crop rotation can improve yield and profitability over time, control weeds, break disease cycles, limit insect and other pest infestations, provide an alternative source of nitrogen, reduce soil erosion, increase soil organic matter, improve soil tilth, and reduce runoff of nutrients and chemicals, as well as the …
What are the uses of crop rotation?
In addition, crop rotation is helpful in long-term soil and farm management. Rotating different crops can break pest cycles and add extra nutrients to the soil. Crop rotations build soil fertility, preserve the environment, control weeds, diseases, and insects, and add to crop and market diversity (Baldwin, 2006).
What are the principles of crop rotation?
The basic principles of crop rotations are as follows: Deep rooted crops should be succeeded by shallow rooted crops such as cotton, castor, pigeon pea-potato, lentil, green gram etc. Dicot crops should be rotated by monocot crops such as mustard, potato- rice, wheat- sugarcane.
What are the three types of cropping pattern?
There are three types of cropping patterns:
- Mixed Cropping: Growing two or more crops simultaneously on the same piece of land. Minimises the risk of crop failure.
- Inter-cropping: Growing two or more crops simultaneously in the same field in a definite pattern.
- Crop Rotation:
What is 2 crop rotation?
ยป Crop rotation is an important strategy for managing some diseases, weeds, and insect pests of vegetable crops. Crop rotation involves planting a sequence of different kind of crops in a location over a number of seasons (Figure 1).
What is the use of crop rotation explain it with one example?
With crop rotation, particular nutrients are replenished depending on the crops that are planted. For example, a simple rotation between a heavy nitrogen using plant (e.g., corn) and a nitrogen depositing plant (e.g., soybeans) can help maintain a healthy balance of nutrients in the soil.
