Farmyard manure is a simple byproduct of farmyard animal waste, often cow dung and urine, but there are other kinds of manure that are used as fertilizer and are common all over the world depending on the location. Farmyard manure helps to improve the soil structure. It expands the capacity of the soil to hold more water and minerals. It also boosts the soil's microbial activity, which improves mineral delivery and plant nutrition. Other examples of farmyard manures include poultry wastes, droppings of sheep and goats, and fish wastes. This article will explain to you about Farm Yard Manure which will be helpful in preparing the Agriculture Syllabus for the UPSC Civil Service exam.

Farm Yard Manure

What are Manures?

• Manure is the degraded form of dead plants and animals that are spread on the soil to boost productivity.
• Manures are a cost-effective and natural source of fertilizer.
• Excreta from humans and animals are also utilized as manure. The nitrogen, phosphorus, and potassium content in livestock manure is high.
• Because manure is high in organic matter and humus, it promotes soil fertility.
• These are more cost-effective in the long term. It is a resource that is both valuable and renewable.
• Manures are plant and animal wastes used to provide plant nutrients. After decomposition, they release nutrients.
• The practice of collecting and utilizing waste from animal, human, and vegetable sources to improve crop productivity is as old as agriculture itself.
• Organic materials derived from animal, human, and plant residues that contain plant nutrients in complex organic forms are referred to as manures.
• Manures with low nutrient content per unit quantity have a longer residual effect than fertilizers with high nutrient content, in addition to improving soil physical properties.
• Manuring is the process of adding manures to a garden. Manuring should be done on a regular basis, or the plants will get feeble.
• Based on the concentration of nutrients, manures can also be classified as bulky organic manures or concentrated organic manures.

What is Farm Yard Manure?

• Basically, cow dung, cow urine, waste straw, and other dairy wastes are used to create farmyard manure.
• FYM contains a high proportion of organic material, which feeds soil organisms and is necessary for maintaining active soil life, and it is high in nutrients.
• A small amount of nitrogen is directly available to plants, while the majority is made available as the Farmyard Manure decomposes.
• When cow dung and urine are combined, the plants receive balanced nutrition.
• Potassium and Phosphorus availability from farmyard manure is comparable to that of inorganic sources.
• Farmyard manure is made up of two parts: solid phase (dung) and liquid phase (urine).
• Using farmyard manure increases soil fertility.
• Farmyard manure is made of simple ingredients (cow dung), but the process of turning it into a functional product takes time and labor.
• Farmyard manure is most beneficial to vegetables such as carrot, tomato, sweet potato, potato, radish, onion, and so on, as well as crops such as rice, sugarcane, napier grass, coconuts, mango, banana, and oranges.

Preparation of Farmyard Manure

• There is no complicated procedure for preparing farmyard manure.
• All you have to do is collect the cow dung and urine into an even layer beneath a simple roof to keep it from getting too wet and exposed to direct sunlight.
• If the mixture becomes too dry, more dung and urine are added, along with some water.
• In about six months, the farmyard manure is ready for use as fertilizer on fields.
• Manure spreaders can be used to apply partially-decomposed farmyard manure to the ground three to four weeks before planting crops.
• This exposure to the elements will allow the manure to decompose more quickly and provide nutrients to the soil.
• If there is a long period of time between spreading the manure and planting the crops, the nutrients may be washed out of the soil by heavy rain.
• If the manure has aged sufficiently, it can be applied immediately before the crops are planted. Farmyard manure is beneficial to vegetable and fruit crops.

Preparation of Farm Yard Manure

Farm Yard Manure - Common Process

• Farmyard manure is a decomposed mixture of cattle dung, urine, bedding materials like straw and litter, and leftovers from the feed the animals were given.
• Daily collections of the dung and urine-soaked waste from the cattle shed are made and dumped into trenches that are 6-7 meters long, 1.5–2 meters wide, and 1 meter deep.
• Up to a height of roughly 0.5 m above the ground level, each trench is filled.
• The heap's top needs to be shaped like a dome and covered in cow dung earth slurry plaster. After three to four months, it is ready to be applied.
• This method can prepare 7 to 8.5 cubic meters of manure annually for each cow.

Farm Yard Manure - Factors Affecting Nutritional Build up

• Age of Animal: Growing animals and cows that produce milk retain in their systems the nitrogen and phosphorus needed for productive functions like growth and milk production, and the excreta do not contain all of the plant food elements present in the feed.
• Older animals that are inferior excrete more than what they do consume, including waste from their body tissues.
• Feed: Excreta produced are similarly enhanced when the feed is high in plant food elements.
• Nature of Litter Used: Leguminous plant waste and cereal straw were both employed as litter, which add nitrogen to the manure.
• Aging of Manure: As manure ages, it becomes richer and less voluminous.

Farm Yard Manure - Benefits

• Farmyard manure enriches the soil with humus and slowly-released nutrients which helps retain nutrients and water.
• Heavy soils are broken down with its aid. Farmyard manure gives sandy and light soils more texture.
• Farmyard manure is a natural source of readily available nitrogen.
• By applying farmyard manure, worms are drawn to the soil and are excellent for mulching.

Farm Yard Manure - Disadvantages

• Its decomposition releases harmful gases into the atmosphere, polluting it.
• Certain micronutrient availability is reduced.
• When compared to fertilizer, FYM necessitates a higher cost per unit weight of nutrients during handling, storage, and application.

Conclusion

The application of farmyard manure has numerous advantages. However, their application not always holds good because as it breaks down, toxic gases are released into the air, polluting it. Farmyard manure also reduces the availability of some micronutrients. In comparison to fertilizer, farmyard manure requires more nutrients per unit of weight for handling, storage, and application.
