No soil erosion contour farming benefits

No soil erosion contour farming benefits, advantages, history, origin and need are explained here. How contour lines farming helps to reduce soil erosion is given here.

No soil erosion contour farming benefits

contour line advantages – Contour farming is sustainable agriculture in active form. Slope land tilling is done in contour farming. The practice of tilling slope land along elevation lines is done in contour farming. This is beneficial to conserve rainwater and reduce soil erosion. Furrows, crop rows and wheel track across the slope acts as reservoirs and catch the retained rainwater.  

Contour farming is not a new farming model instead it is a traditional farming model which has been practised for centuries. Contour farming is mostly practised in the region where irrigation farming is important. Contour farming in the United States was first practised in the 19th century. 

In the 1930s US Soil Conservation Service has done essential efforts to promote contouring as an essential part of soil erosion control. Due to the effort of US soil conservation services contouring became popular and it was adopted worldwide by farmers. Contour farming has been proven to reduce fertilizer loss. The contour farming method is useful for preventing the loss of water, power and time consumption. Control farming technique is important to increase crop yield and reduce erosion.

While counting contour farming benefits it is very helpful to absorb the impacts of heavy rains. In straight line planting rain often wash away the topsoil. Soil erosion prevention is one of the main advantages of contour farming. Contour farming becomes more effective when used along with such practices including terracing, strip cropping and water diversion.

What is Contour farming in agriculture

Contour farming is also known as contour plowing and contour bunding. Contour farming is a farming practice in which planting or ploughing is done across the slope following its elevation contour lines. Water break is created by contour lines Which reduces the formation of gullies and rills during heavy rainfall. This allows more time for rainwater to settle into the soil.

In contour plowing the ruts made by the plough are not parallel instead they are erect to the slope. Furrows curve around the land and are level, this method is helpful for preventing tillage erosion. Contour bunding is a process where stones are placed around the contours of slopes. The importance of contour ploughing is huge in contour farming because contour ploughing is helpful to reduce soil erosion and less consumption of water. 

History of contour farming

Contour farming was first developed by the Phoenicians. Phoenicians are responsible to spread contour farming modal throughout the Mediterranean. However, the Roman preferred straightforward cultivation which became standard. In 1930 contour farming was promoted by the US soil conservation service which is currently Natural Resources Conservation Service. In 1935 dust bowl was a big problem in America. Soil erosion was a huge problem along with desertification in 1935 during the dust bowl period.

Soil conservation service state governments and agriculture universities worked together, they organized some agriculture programs such as the University of Nebraska to promote the contour method to farmers. All of them did good hard work and the effort was praiseworthy by 1938 the adoption of new agricultural techniques such as contour farming has reduced soil erosion by 65%. 

Cover crop in agriculture

Cover crops are fast-growing crops and these crops are planted to reduce soil erosion and increase nutrients in the soil. Cover crops are beneficial to plants because they provide organic matter to the soil. Some examples of cover crops are rye, cowpea, vetch and buckwheat etc.   

Cover crop growing season

Cover crops are mainly grown between the rows and when cash crops are not grown. 

FAQ

What is soil erosion?

After heavy rainfall lots of soil is washed away with the rain resulting as soil erosion. Soil erosion led into the wastage of nutrients and other components of soil which are good for the growth of plants. Therefore it is necessary to prevent the soil erosion and contour technique is one of the best technique to prevent soil erosion.

How to prevent soil erosion?

According to agriculture experts contour farming technique is helpful to to prevent soil erosion.

What is contour bunding in agriculture?

Contour bunding is a farming practice beneficial for reducing soil erosion. In contour bunding stones are placed around the stopes of contour.

What is the benefit of contour ploughing in agriculture?

Contour ploughing is helpful to reduce soil erosion.

What is the dust bowl in America?

Dust bowl in the USA was actually a time period of severe dust storms that use to damage the agriculture and ecology of America and Canadian parairies.

What are the major benefits of contour farming?

Contour farming benefits are given below:
Contour farming reduce fertilizer loss.
Contour ploughing or farming reduce power and time consumption.
Agricultural contour farming reduce loss of important nutrients of soil.
Contour method in agriculture Increases crop yield.
Most importantly contour lines in agriculture reduce soil erosion.
