What is crop rotation explain Class 8?
The practice in which different types of crops are grown alternately in the same field or soil is called crop rotation. In crop rotation cereal crops like wheat, maize,paddy, millet are grown alternately with leguminous crops like pulses,peas,beans,groundnut,clover in the same field.
Why is crop rotation important?
In this situation, crop rotation helps conserve water on farms, because the need of irrigation is decreased. Some additional benefits of better water holding capacity are: Reduction of runoff and loss of nutrients from soils. Lower risk of flooding because soils act as a sponge. Prevention of erosion.
How does crop rotation work?
Unlike intensive fertilizer agriculture, crop rotation systems work by naturally replenishing nitrogen levels in soils through alternating leguminous crops with other crops. According to research, nitrogen fixed by legumes even remains longer in the soil than the synthetically provided form [5].
How many years of crop rotation?
Farmers usually do not follow one specific crop rotation plan. They choose to alternate crops based on their individual requirements, possibilities, environmental conditions and budget. For example, one farmer might follow a seven-year crop rotation scheme as follows: First year: Corn. Second year: Oats.
What is the basic principle of crop rotation?
The basic principle is to plant leguminous crops (e.g. pulses, alfalfa, bluegrass, clover) after the cereal crops (e.g. wheat, oats, maize, rice), and then leave the land undisturbed for at least one season.
Why did ancient civilizations use crop rotation?
One of the main reasons why ancient civilizations applied crop rotation was to prevent the spread of pests, weeds and diseases. With the introduction of chemicals into the agriculture, the need to rotate crops disappeared. However, the widespread application of these chemicals has led to some serious cases of poisoning, contamination of the environment and even the increased resistance of pests to the active substances.
What is crop rotation?
Crop rotation is a farming technique dating as far back as the Roman Empire or Ancient Greece. Although ancient farmers didn’t fully understand the science behind the crop rotation, they observed that growing the same crop at the same plot for several years depletes soils of nutrients and decreases crop yield.
What happens when farmers use a pest control system?
Once farmers applied this system, the soil quality improved and losses of crops due to the pests or diseases dropped. Simple and effective.

How does crop rotation affect nitrogen?
Along with the other benefits of crop rotation, it may impact the rate of nitrogen mineralization .#N#Even on the conversion of organic nitrogen to mineral nitrogen by change of soil temperature, moisture, plant residue, pH and tillage practices. A common use of nitrogen it is been showing up over the past 50 years.#N#The use of this in large amounts, especially to maximize farming production, increases the nitrogen within the soil profile of certain farms.#N#Rotations that include nitrogen by producing legumes such as peas, beans, and alfalfa give to next crops with large amounts of this critical nutrient.#N#A research shows that nitrogen from legumes remains in the soil longer than the nitrogen in synthetic fertilizers, leaving less to leach into groundwater or runoff fields and pollute streams.#N#Crop rotation plays a key role in reducing the risk of nitrate, leaching into surface and groundwater. The system improves the availability of soil nitrogen and reducing the nitrogen fertilizer used.
What is the logic behind crop rotation?
The logic behind crop rotation is when the same crop is grown at the same place for several years the soil is depleted of certain nutrients. Doing rotation, a crop that draws one kind of nutrient from the soil is followed during the consequent season by a crop that returns the nutrient to the soil or draws a distinct ratio of nutrients.
Why is my crop yield decreasing?
This is because if the same type of crop is planted in the same area, the plant will continue to drain same nutrients from the soil. . Second, certain pests can reach levels that are hard to control.
Why is nitrogen used in agriculture?
The use of this in large amounts, especially to maximize farming production, increases the nitrogen within the soil profile of certain farms .
How old is crop rotation?
The crop rotation is a thousand years old technique that has been proven to help the environment, improve the soil and so many other things.
Why did they do crop rotation?
This means they did not even know its impact on the environment. Typically, they did it because of the seasonal calendar of the planting of crops, which was set traditionally as a planting pattern. Here are some of the known advantages and disadvantages of crop rotation. 1.
How does crop rotation help with erosion?
Crop rotation also helps reduce raindrop impact on the soil and general erosion by water because the roots of the plants hold the top layer soil together . Trees planted together with crops in the farms also assists in preventing soil erosion.
How does crop rotation affect the life cycle of a plant?
Similar plants tend to have the same pathogens; therefore, crop rotation intercepts the pest life cycle and their habitat. A cycle entails similar events that happen in constant rotation, meaning that the infestation of pests and diseases happens in the season.
Why do crops need a mix up?
Each crop type adds up or absorbs different soil nutrients to the soil; therefore, it needs a mix up of a variety of plants to make them more balanced. Knowing the type of plants to grow after a rotation is imperative to avoid either excessive buildup of nutrients or excessive absorption of nutrients from the soil. 4.
Why do we get a variety of crops after each season?
Not only does one get a variety of crops after each season because of the incorporation of different crop types, but also a general bounty harvest. Some scientific evidence proves a 10 to 25% increase in crop yield in crop rotation rather than monoculture.
What happens when you plant the same crop?
Prolonged planting of the same crop type leads to the depletion of specific nutrients in the soil. Each crop type has a different nutrient interaction with the soil, and each of them releases and absorb different types of nutrients.
Why do farmers plant different plants?
As a farmer, when you are aware of the kinds of pests and diseases that break out at a given time of the year and the crops affected, you can plant the host plant at a different season when the chances of infestation are low. This lowers the risk of plants getting infested and equally allows the farmer to grow crops each season without using pesticides, which is good for the environment.
Why do farmers rotate their crops?
Before commercial fertilizers and pesticides, farmers rotated their crops. This occurred as early as Roman times and in ancient Asia. In medieval times, farmers had three fields: one of winter wheat or rye, one of peas or beans, and the other lay fallow (unplanted). This provided for the different nutritional needs of the people while removing/replenishing different soil nutrients and allowing the soil to rest for a season. In the southern United States, George Washington Carver taught farmers to rotate soil-depleting crops like cotton with soil-enriching crops like peanuts or peas. Today, organic farmers who understand crop rotation benefits make sure to rotate their crops so they can avoid the use of pesticides and commercial fertilizers.
What makes a good soil for a vegetable garden?
Those minerals include magnesium, potassium, calcium, iron, zinc and selenium, among others, which are essential to our health. Other elements, such as nitrogen, may not benefit us as much as they benefit the growth of the plant. Chemical fertilizers replenish only a few of these nutrients, mainly nitrogen, potassium, and phosphorus. By composting, you place those minerals back in the soil. By rotating crops, you grow a food that takes different minerals instead of depleting the same ones.
What are the advantages of crop rotation?
7. Improvement in Soil Structure. There is reduced compaction of soil when carrying out crop rotation which improves the physical condition of the soil. This is a major advantage as it allows soil conditions in which good seed germination and proliferation of root can occur.
Why should farmers consider crop rotation?
3. Increased soil nutrients.
How does rotation help the soil?
Crop rotation also helps to increase the organic matter of the soil which is left behind by microorganisms found in various types of crops planted. Animals that graze on unplanted grasslands excrete manure which can act as a natural fertilizer for the soil and prepare it for next season. 2. Higher crop yields.
How to prevent soil erosion?
Soil erosion carries away most of the topsoil layer through wind or water. Plants (like cover crops) anchor the topsoil layer through their roots, preventing soil erosion. Planting cover crops or crawling plants will help to prevent soil erosion by giving the ground adequate crop cover and allow the land to rest in the meantime . Crop rotation helps in reducing rainfall impact on the soil and general erosion by water. Trees being planted alongside crops will provide a better preventing of soil erosion.
How does crop rotation affect the productivity of the land?
Crop rotation increases the productivity of the land from a single seasonal harvest. It does not just provide a different variety of crops because of incorporation of different crop types, but it is a general bounty harvest.
Why is crop diversification important?
Due to the farmer not having the specialty in a particular crop , he may be unable to produce high yields of that crop. Crop diversification requires investment in different planting techniques for each unique crop , this costs time and money as different crops require a different amount of time and attention.
What is crop rotation?
Crop rotation is a farming practice employed by farmers for centuries. It is defined as the intentional planting of different types of crops on different parts of the land during different seasons in a sequential fashion. This system entitles farmers to give their farms a break in a particular season, allowing the land to rejuvenate for ...
Why is rotation important for crops?
2. It improves soil conditions. Crop rotation can cause a big difference in root structure over time, especially when you plant crops that have tap or fibrous roots. The diversity in root structure enhances the chemical, biological, and physical structure of the soil. This improves the organic matter and nutrients and increases ...
What is crop rotation?
Crop rotation is a low-input form of sustainable agriculture that has been practiced for a long time, dating back to first century B.C. However, agriculture practices changed in the 1940s and 1950s when high fossil fuel technologies and intensified monocultural cropping was adopted on most lands, with producers believing that these would be more beneficial than the rotating method. However, this newer system required a lot of equipment, fuel, fertilizers, and other agricultural chemicals. Today, there is a growing concern about the environment and increasing demands for a more sustainable agriculture industry and production methods. As a result, more people are taking a closer look and renewed interest in crop rotation.
How does rotation help soil?
1. It reduces soil erosion and water runoff. #N#Rotating crops improves soil tilth and microbial communities, which in turn brings down soil erosion because it enhances water infiltration, minimized surface runoff, and a more stable soil structure.
Why is diversification important for farmers?
This means you can distribute the workload and resources used throughout the year. It also gives farmers more options in selling various produce and not be reliant on just one crop and market price. YouTube.
