FIELD OF THE INVENTION
[001] The present invention relates to a method to study the attributes of farm yard manure and in particular relates to a method to study the farm yard manure attributes for paddle operated mechanical applicator.

BACKGROUND OF THE INVENTION
[002] As India is a tropical country, the soil is deficient of humus content. Manure added in the beds of soil is excellent source of organic matter as it enhances quality of soil after application. To increase the social acceptance of livestock products it is a need to recycle the animal residue. Now a days, biogas plant and compost pit are present at home of farmers for production of farm yard manure and biogas. For maintaining long term fertility of soil and reduce major forms of pollution, concept of organic farming is introduced. Organic farming also produces quality which is high in nutrient content and adequate quantity. Organic farming also reduces conventional sources of energy and develops potentialities in human beings. By understanding the above stated points organic fertilizers that is farm yard manure becomes a better option for growth of crops. In order to improve the soil structure and suitability of soil fertility, soil organic matter is the key tool. The agricultural technologies are enhancing rapidly, but application of farm yard manure still remains a tedious and difficult task for crop growers.
[003] Previous studies depicts that equipment which are designed to control and apply the manure on land reveal large coefficient of variation in distribution. In order to design an efficient machine for operation of different systems of compost applicator, suitable knowledge of physical properties is a need. Former review of available chemical properties is present, but very less researchers focus on the physical properties of farm yard manure. Some researchers also studied the effect of manure property on performance of various mechanisms. Spreading distances have effect on particle size and it depends on spreader distribution of poultry litters. They observed that on the comparison of smaller particles, the large particles were distributed more uniformly and on larger width. The small particles landed closer to the spreader. It was observed in design of a manure applicator which had characteristic properties to apply solid waste, maximum lump size and moisture content presents problems in conveying manure due to physical properties.

[004] Thus, there is a long felt need for a method that is capable of studying the attributes of farm yard manure for paddle operated mechanical applicator.

DETAILED DESCRIPTION OF THE INVENTION
[010] The embodiments of the invention will now be described herein, with reference to the accompanying examples and drawings. It will be understood by those skilled in the art that the foregoing general description and the following detailed description are exemplary and explanatory of the invention and are not intended to be restrictive thereof.

[011] The present invention provides a method for studying the attributes of farm yard manure for paddle operated mechanical applicator.

[012] According to an embodiment of the present invention, the method 300 begins at step 301, wherein, at least five manure pits of varying depths are employed. At step 302, cow dung is cast off into the pit. At step 303, manure becomes ready to use. At step 304, samples are collected and analyzed for physical and frictional attributes of farm yard manure.

[013] According to an embodiment of the present invention, the physical attributes are bulk density, moisture content, angle of repose and dry matter content.

[014] According to an embodiment of the present invention, the frictional attributes are angle of repose and coefficient of friction for farm yard manure.

[015] According to another embodiment of the present invention, the depths of manure pit are 0-18cm, 18-36cm, 36-54cm, 54-72cm, 72-90cm.

[016] According to yet another embodiment of the present invention, the cow dung is cast off daily into the pit.

[017] According to an embodiment of the present invention, the manure becomes ready for use in 4-5 months.

[018] According to another embodiment of the present invention, the bulk density is used to analyze the stability, bearing capacity and degree of compaction of manure.

[019] According to yet another embodiment of the present invention, the moisture content is determined by oven drying method.

[020] According to another embodiment of the present invention, the angle of repose is measured by the expression –
? = where µ =

EXAMPLES
[021] According to an embodiment of the present invention, the said method was followed to check the physical attributes of farm yard manure (Table 1). Moisture content observed in farmyard manure was 27.95832, 35.46512, 38.45597, 45.05171 and 46.8945 % at respective depths of manure pit. Bulk density measured in FYM was 1.66, 1.724, 1.8, 1.8and 1.89 kg/m3 at different depths of manure pit. Dry matter content measured for farmyard manure was 72.04168, 64.53488, 61.54403, 54.94829 and 53.1055%. The angle of repose for FYM was 35.06174°, 39.19322°, 39.8686°, 47.478° and 53.7372° (Figs. 1 – 4).
