2. Definition of ley farming T he growing of grass or legumes in rotation with grain or tilled crops as a soil conservation measure . Example: grass + stylosanthes This system involves the use of various annual and perennial crops (grasses, legumes), grown in long-term and short-term, to manage the soil.

4. Ley Farming E mphasis is placed on the value of grass-legume mixture to get fodder for livestock and improve soil fertility for obtaining higher yields of arable crops . For maximum crop yield, the best use of available land. L atest methods of crop husbandry are put into practice.

5. How ley farming was introduced? Highest yield Cultivated fields were abandoned when yields started to decline Yield tend to decrease with successive crops New fields were taken over for cultivation Farmers have recognised that yields of arable crops are the highest after ploughing up of old grasslands.

6. Contd. Shifting cultivation Fallowing of land Next stage of agrarian development Legumes introduced in place of fallow ‘Crop rotation’ was thus initiated to obtain better yield with maintenance of soil fertility

7. Advantages 1. Improvement of nitrogen content for subsequent plantations Legumes improve the fertility of the soil, the quality of the grain and increase the volume of crops. Most of the nitrogen in the soil gets used up by grains, so the alteration with legume crops gives an extremely positive effect . 2. Restoration of soil and organic matter structure Legume pastures can't produce the desired effect if used separately; in this case, grass can become an excellent helper, since it promotes the production of organic materials. It has been scientifically proven that meadow grasses increase soil organic matter by about 0.1% per year .

8. 3. Controlling the growth of weeds C attles that eat unwanted plants can graze on these pastures. This approach is especially effective in combating weeds annually. 4. Preventing deep drainage and erosion On perennial pastures, the root system develops quite well, which provides access to water and nutrients at a considerable depth . As a result, the top layer becomes dry, and the loss of water and useful substances during drainage is prevented. Shallow soil is quite unstable as it does not hold water well, so ley pastures are able to become good tools for reducing drainage.

9. 5. Improving livestock efficiency During the grazing season, animals receive high nutritional support so farmers can obtain milk of better quality . 6. Natural fertilizers

10. Disadvantages C onsiderable time and investment of lots of money . Problems could also arise due to improper preparation of the seeds, their low quality or unfavorable weather conditions . It is necessary to remove all modern forms of plant cultivation from the soil before sowing new under the ley farming system. Sometimes, in order to ensure a good future harvest, it is required to observe a certain interval before removing and sowing plants.

11. Conclusion Ley systems are more profitable than continuous cropping . I ntensity of ley increased, the profit per year is also enhanced. C ost of cultivation is low due to reduced cultivation operation, unlike cultivation of cereal crops, where these costs are considerable. It is eco-friendly and very relevant to the arid and infertile soil profile to achieve progress. The technology is not specific for the undermined areas and ecosystems, so it is to be adopted everywhere to raise the outputs for the betterment of socio-economic conditions of the farming community.
