General

On several farms an application of manure close to the ground has been implemented. It's not only a low-emission technique but also reduces the loss of nutrients and is therefore important to protect ground water from excessive nutrient input. In particular the application of manure by trailing shoe has proved successful. The manure is applied not onto the plants but onto the ground beneath. Thus the manure is applied very precisely, accurate dosed and near to the roots. This results in a higher rate of absorption of nutrients by the plants and less input of redundant nutrients into the ground water. Nearby surface waters are protected as well because the manure is not situated onto the plants and therefore not in the risk of being washed into a surface water.        

When applying, the farmer has to get used to the new technique which can be demonstrated by the customer service of the distributor. Regular use of the trialing shoe to get used to the handling.

To monitor the effect of the good practice, the water quality of ground water and surface water can e tested before and after using the trailing shoe.

Benefits

Higher acceptance from local residents because of decreased unpleasant smell. Also he is already prepared for new requirements.

Bottlenecks

The investment for the new equipment and to learn how to work with this equipment

Lessons learned

- New equipment is expensive but an advantage when it comes to environmental protection
- Plant growth improved because of high disposability of nutrients
- Farmer's interest in technique helps to learn the handling

Impact

- Socio- economic resilience: Growth of feeding plants can improve due to higher disposability of nutrients
- Animal health and welfare
- Production efficiency and meat quality
- Environmental sustainability: Input of nutrients in ground and surface water is reduced, especially the input of nitrogen

Costs and benefits of the application of liquid slurry with trailing shoe

Distribution on field of liquid manure with trailing shoe reduces the loss of nutrients and increases the efficiency of organic fertilization, because the manure is applied not onto the plants but on the ground near to the plants roots. This results in a higher rate of absorption of nutrients, lower ammonia emission into the air and lower leaching in to the ground and surface water.

Simulation of the cost and benefits from the economic point view has been carried out considering the production costs of the finishing and cow calf typical farms in Ireland. Economic variables taken into account under the hypothesis of the adoption of this technique are the reduction of the use of chemical nitrogen fertilizers (due to higher efficiency of the organic fertilization), and the difference of the cost charged by an external contractor for the application of manure with the trailing shoe instead of the splash plate or other conventional technique. The following are the value of N fertilizer value according to different application method, showing that  a reduction in chemical fertilization is possible

Cost charged by an external contractors for manure distribution by trailing shoe range from 90-95 €/hr. Distribution manure with conventional technique (splash plate) is charged 50 €/hr. It was assumed that application by means of the different application methods require the same amount of hour per hectare.

The following tables show the costs and benefits of this technique for different farm types in Ireland.
