What is fym in agriculture


Farmyard manure (FYM) is an important organic resource for agricultural production in livestock-based farming systems in the semi-arid tropics of India. However, use of FYM has been affected by a shortfall in its supply, by increasing demand for plant nutrients, and by the increasing use of manufactured fertilizers.

What is FYM in farmyard manure?

FYM refers to the decomposed mixture of dung and urine of farm animals along with their litter and fodder fed to the cattle. FYM is one of the components of Integrated Nutrient Management (INM) as it a cheap and easily available source of organic nutrients. What are we waiting for? Let’s get into the details of farmyard manure preparation methods.

What is FYM and how does it work?

FYM is rich in nutrients A small portion of N is directly available to the plants while a larger portion is made available as and when the FYM decomposes When cow dung and urine are mixed, a balanced nutrition is made available to the plants

What is the nutritional status of FYM?

Application of FYM improves soil fertility. Nutritional status of FYM (%) Nitrogen 0.5000 Phosphorus 0.2500 Potassium 0.4000 Calcium 0.0800

What does old FYM mean?

Old FYM = manure that has been stored for three months or more and has an estimated ammonium-nitrate and nitrate-nitrate content of 10% (cattle and sheep FYM) or 15% (pig and duck FYM) of the total nitrogen. e.


What does FYM mean in farming?

Using farmyard manure (FYM)

What is FYM describe in detail?

FYM stands for Farm Yard Manure. It is prepared mainly from cow dung, cow urine, waste grass, and other dairy products. Properties of FYM.

What is the full form of FYM and NPK?

Index Terms— Farm Yard Manure (FYM), Nitrogen, Phosphorus, Potassium (NPK) based fertilizer, Algal.

What is compost and FYM?

Compost can be made from a wide variety of materials, such as livestock manures, untreated wood and garden waste or waste food for example. Composting is “the natural breakdown of biodegradable materials through mixing, self-generated heating and aeration to form a stable, soil-like material”.

What is the NPK content of FYM?

Farmyard manure refers to the decomposed mixture of dung and urine of farm animals along with litter and left over material from roughages or fodder fed to the cattle. On an average well decomposed farmyard manure contains 0.5 per cent N, 0.2 per cent P2O5and .

How is FYM prepared?

This method is commercially adopted by farmers usually pits of 8m x 2m x 1m dimensions are prepared, which are filled in layers by the mixture of dung, urine and litter up to about 50 cm above ground level. The top is nicely filled, pits is covered by dry soil and then plastered by mud paste.

What is SSP fertilizer?

SSP is the most popular phosphatic fertilizer after DAP as it contains 3 major plant nutrients namely Phosphorus, Sulphur and Calcium along with traces of many micro-nutrients. SSP is indigenously available and supply can be made at short notice. Oilseed farmers have special preference for SSP.

What is NPK fertilizer?

NPK fertilizer provides all the essential nutrients required by plant – Nitrogen (N), Phosphorous(P) and Potassium (K). The nutrients for vegetative growth in stems, roots particularly during the early stages, root growth, seed and flower formation, bud growth and ripening of fruits.

What is enriched FYM?

The manure is made from mixing one cart of cow dung, 5 kg of super phosphate, potash and urea each, one quarter bag of field soil (soil taken from the field) and a handful of calcium mixed well, and shade dried for 15 days and used. “One cartload of this manure is sufficient for an acre.

How do I apply for FYM?

Apply 1 tonne of fully decomposed FYM or compost to 20 cents nursery and spread the manure uniformly on dry soil. Basal application of DAP is recommended when the seedlings are to be pulled out in 20-25 days after sowing in less fertile nursery soils.

Is FYM and compost same?

– Science | Shaalaa.com….Solution.Farmyard ManureCompost ManureIt is the decomposed mixture of cattle excreta, urine, litter, and leftover organic matter (roughage or fodder).It is prepared from farm and town refuse such as vegetable and animal refuse, faecal matter, and sewage waste.1 more row

What is the best farmyard manure?

Ideally, the best manure for gardens is probably chicken, since it has a very high content of nitrogen, a need all plants have, but it must be composted well and aged to prevent burning plants. Chicken manure is a rich source of nutrients and is best applied in fall or spring after it has had a chance to compost.

Why is farm yard manure soluble?

This farm yard manure FYM will decompose in moist soil to improve the soil structure and release the nutrients contained in it, in the soluble form for growth of the crop. If it is applied too long before sowing the crop, the nutrients are lost by leaching by rain water.

How is cattle dung decomposed?

Cattle dung is rapidly decomposed by high temperatures, when the complex organic form of nutrients contained in them are converted to simple inorganic forms of nutrients which are washed down by high rainfall.

What happens when gypsum is used?

If gypsum is used, ammonium sulphate and calcium carbonate are formed. When manure + heap dries up, the ammonium sulphate reacts with calcium carbonates to re-form ammonium carbonates, which are then decomposed to ammonia, carbon dioxide and water. ADVERTISEMENTS:

Should farmers be provided with other sources of cheap fuel?

Farmers should be provided with other sources of cheap fuel. A Biogas plant should be provided to them at a subsidized rate. The floor of the cattle shed should be cemented to prevent from soaking in the urine. Sufficient quantity of waste organic material should be used for soaking the urine. ADVERTISEMENTS:

Why is duck manure included in the fym?

Typical total nitrogen content of FYM (fresh-weight basis) Duck farmyard manure is included here because the availability of its nitrogen is generally lower than that of other poultry manures. To convert kg/t to units/ton, multiply by 2. a.

What are the factors that determine the nutrient content of livestock manure?

The nutrient content of livestock manures will depend on several factors: type of livestock, diet and feeding system, the volume of dirty water and rainwater entering storage facilities, and the amount of bedding used. Consequently, the nutrient content of manures produced on any particular unit may vary significantly from …

How much nitrogen is in fym?

FYM contains approximately 5 to 6 kg nitrogen, 1.2 to 2.0 kg phosphorus and 5 to 6 kg potash per tonne. The quantity and quality of FYM mainly depend upon the type (draught, mulch) and age of the animals, the way they are feed and the care taken to collect and store the material.

Why is farmyard manure important?

Farmyard Manure has a high proportion of organic material which nurtures soil organisms and is necessary for maintaining an active soil life. Typically, about half of the nutrient content of farmyard manure becomes available for crop growth during the first year after it is applied to the soil.

What are the properties of farmyard manure?

FYM is highly useful and some of the properties of FYM can be given below; FYM has a high proportion of organic material which nurtures soil organisms and is essential in maintaining an active soil life and it is rich in nutrients.

How many pits should a farmer have?

Every farmer should have at least 2-3 pits so that the first pit gets covered after adding soil and then the second pit should start filling. During this time, the FYM of the first pit will be ready to be added in the field, which will again obtain free after using manure.

Is farmyard manure good for the soil?

The application of this source of organic improves the physical, chemical and biological condition of the soils . FYM can supply all the nutrients required by the plant and it is prepared by using cow dung, cow urine, waste straw, and other dairy wastes.


Application of farm yard manure (FYM) is known to maintain soil productivity longer than inorganic fertilizers (Flaig, 1975). Farm yard manure contains all the macro- and micronutrients required for plant growth (Hesse, 1984), but its main effect is due to nitrogen, phosphorus, and potassium (Heck, 1931).
