No

2.1 Short description of the Technology

Definition of the Technology:

The addition of organic matter, such as compost, to soils on farms can enhance soil health with benefits for soil organisms, soil structure, carbon sequestration and plant production.

2.2 Detailed description of the Technology

Description:

Application of organic matter to soils, in the form of compost, helps enhance soil organisms and structure for improvements in overall soil health. This technology has been applied to 36 hectares of a 300 hectare organic arable farm that practices a rotation of 2 years grass ley, followed by a winter cereal and then two spring cereals with cover crops in the period between the two spring crops. The technology has been trialed in the south of England (Berkshire) where the average annual rainfall is around 690 mm and the soil is mostly gravel, silt and clay soil with low organic matter – making it challenging to cultivate.
The practice has been to import certified green waste compost to apply to fields on a rotational basis before the winter crop, as it requires more nitrogen than the spring crops. The application was planned for this period in the rotation as spring spreading can damage the soil through compaction after the winter crop has been harvested.
The sources of green waste varied, with 900 tonnes of composted PAS 100 certified green waste from a local waste company, and 500 tonnes of green waste from a local camomile producer, both in 2019/2020. The compost was stored in windrow heaps for 6 months on the grass leys turning once during this time. For the application, a contractor then used a spreader before soil cultivation for the winter crop. This technology is ongoing.
The primary aim of the application of organic matter is to improve soil fertility and the soil's health. This in turn results in better crops.
Challenges to overcome with this technology are issues with compaction from spreading activities and the cost of compost purchase and haulage. Compaction can be alleviated through autumn spreading, yet costs can be prohibitive. So, far the benefits of the technology application are limited as it will take a long time achieve the full impacts of increasing soil organic matter, especially in the soil type that is present on the farm, yet the hope is it will have a large impact in the future.

4.2 General information regarding the calculation of inputs and costs

Specify how costs and inputs were calculated:

• per Technology area

other/ national currency (specify):

£GBP

If relevant, indicate exchange rate from USD to local currency (e.g. 1 USD = 79.9 Brazilian Real): 1 USD =:

0.85

4.3 Establishment activities

	Activity	Timing (season)
1.	Procurement of compost	Spring
2.	Application of compost (27.4t/ha)	Autumn

4.4 Costs and inputs needed for establishment

	Specify input	Unit	Quantity	Costs per Unit	Total costs per input	% of costs borne by land users
Fertilizers and biocides	Compost purchase, haulage and spreading (£11 per tonne)	ha	36.0	303.0	10908.0	100.0
Total costs for establishment of the Technology					10908.0
Total costs for establishment of the Technology in USD					12832.94

Comments:

Compost was sourced, delivered, arranged in windrows and later spread by a single contractor for a set price (£11 per tonne @27.4t/ha over 36 ha).

4.5 Maintenance/ recurrent activities

Comments:

No ongoing maintenance as organic matter will incorporate into soil over time. Ongoing maintenance would be to repeat the procedure to continue adding matter to the soil over time.

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Comments:

No ongoing maintenance costs as organic matter will incorporate into soil over time. Ongoing maintenance would be to repeat the addition at the right time of the crop rotation again to continue adding organic matter to the soil over time.

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

The cost of contractor haulage and spreading, which is partly driven by current fuel costs.
