The spreading of liquid manure requires certain precautions to avoid harming the environment and the population.
Moreover, a regulation is in place and must be applied correctly to limit pollution. Here is the point about organic manure and the method of spreading it.
What is the spreading of liquid manure?
The spreading of liquid manure is an operation that consists of using specific waste and spreading it on the crops:
– These wastes come mainly from livestock’s excrement and urine, such as cattle, poultry, and pigs.
– Livestock excrements are mixed with the washing water of farm buildings. The volume of water can reach 90% of the mixture.
Manure is a valuable organic fertilizer. It is intended to be stored in tanks to fertilize agricultural land through a spreading process.
Good to know: the spreading of liquid manure requires equipment specially adapted to this operation.
Methods of spreading liquid manure
The spreading of liquid manure is done with a spreader vehicle equipped with a tank containing the liquid manure. This machine is called a slurry tanker and is equipped with
– Either a low boom equipped with a manual or hydraulic slurry flow regulation system. It allows the spreading of the liquid manure uniformly.
– Or a boom with pendulums positioned at a low height to the ground level. It is equipped with hoses to distribute the slurry to be spread. All hoses are attached to the boom. The downpipes are positioned on the lower part of the boom. They are spaced 30 cm apart to distribute the liquid manure evenly and accurately.
Some booms can be equipped with the following:
– an anti-drip system;
– tilt correctors;
– vertical choppers-distributors;
– burying devices.
Good to know: there is a wide choice of slurry tanker models, either trucks or trailers. These machines are available for sale (new or used) or rent.
Regulations regarding the spreading of liquid manure
The spreading of liquid manure is subject to regulations concerning the distances to be respected concerning houses and the environment. The minimum distances for spreading liquid manure are established by decree and defined as follows
– Dwellings of third parties: 15 m if a direct injection of manure into the ground, 50 m with a 12-hour burial period, and 100 m with a 24-hour burial period.
– Environment: 35 m from watercourses (stream, torrent, river, etc.) as well as water bodies (pond, lake), 50 m from water points such as wells, boreholes, drinking water distributors, etc., 200 m from bathing areas, 500 m from fish and shellfish farming areas (shellfish).
On the other hand, prefectural decrees forbid the spreading of liquid manure in the following cases
– on snow-covered or frozen ground;
– on flooded or soaked soils during periods of heavy rain;
– on steeply sloping ground;
– on uncultivated soil;
– on legumes.
The spreading of liquid manure, a matter of environmental protection, is subject to authorization or declaration under the Environmental Code. Hence, getting information from the town hall is recommended for any questions.
