2. Shallow ploughing to protect soil biodiversity

At the end of its 4 years, the ley is ploughed under, typically at the end of July. A crop of stubble turnips and forage rape are sown to be grazed by ewes with lambs at foot. This forage crop allows for effective destruction of the ley. Although ploughing is known to have a negative effect on soil health, the options to kill off a well-established sward are limited. To reduce the soil damage the farm has invested in a new very shallow plough; an ‘Ovlac’ from Spain, a 6 furrow reversible with which it is possible to plough at only 3-4 inches. This forage crop is grazed by sheep and this typically lasts into January. The remaining grazed stubble is ploughed under with the shallow plough and sown with spring wheat, at a standard seed rate.

3. Undersowing & direct drilling for weed suppression
Although not managed organically, Ian wants to eliminate pesticide use, so to help with weed control, the wheat is under-sown with a mix of white clover and yellow trefoil. This is sown on the same day as the wheat with the farm’s own Aitchson seed drill; a typical coulter type drill The drill places the clover/trefoil seed between the drills of the wheat seed. The clover and trefoil mix is not just for weed suppression but also for soil health – as much soil is covered with a plant as possible throughout the year. Bare soil is frowned upon at Honeydale, as there is now considerable evidence that for a soil to function at its best it needs to interact with a living plant root as well as to be fed with good quality organic matter.

Both the white clover and yellow trefoil do not compete with the wheat crop, and once the wheat is harvested there is a crop ‘ready to go’ for grazing the sheep. Incidentally, there is long history of using yellow trefoil in the UK, particularly with spring barley where the two crops were grown together in a continuous rotation.

Although the clover and trefoil is available for autumn grazing it is kept back for early spring grazing by the sheep.

If grazed hard by the sheep in the spring, the farm will experiment with sowing a spring oat crop directly into the clover and trefoil stubble, with a March or April sowing date. If this is not possible, the stubble will be shallow ploughed and the oats under-sown with vetch. The oats are cut in August, with the under-sown crop of either clover/trefoil or vetch going on as a winter cover crop, which is available for spring grazing.

4. Seed mix for wildlife and soil improvement
A wild bird seed mix is slotted into the rotation next, with an emphasis on late spring mechanical weed control to prevent problem weeds getting into the rotation. The mix is a field scale wild bird seed mix, sown annually in the early summer. It is shallow drilled and rolled and left down for a year, then moved to a different field. The aim is to provide food for the birds and also to act as a green manure and soil improver.

5. Nurse cropping for re-establishing grass ley
To complete the rotation, the diverse grass ley is re-established. Honeydale is experimenting with methods to do this and to suppress weeds; typically the ley would be under-sown beneath a spring cereal crop, but this year Honeydale used buckwheat, sown at 18kgs per acre as a nurse crop to protect the under-sown ley from summer heat and sun and to give good soil cover. The frost in November killed the buckwheat and left the new ley.

The bottom line
At the start it was clear the old regime wasn’t working financially, so how will the new model change this?

New crops
Adding value to crops will help, but is proving challenging so far. Ian has looked at ways to turn 5 tonnes of oats into a product he can sell directly for making porridge; this has been more difficult than he first thought. Big processing facilities do not want small quantities and the cost and equipment to process what is a small tonnage of oats is so far preventing this project from progressing.

15 acres of the farm has been planted as fruit orchard, helped by a local nurseryman and the local community, with mostly apple, pear and cherry trees in single varieties. They are planted at a traditional spacing of 30 foot, to allow for sheep grazing between the trees. This increases productivity by having two crops from the same plot of land, as well as the sheep being able to return fertility to the orchard soils. Ways of adding value to the fruit will be considered, such as bottling the fruit for direct sales.

A rural community hub
Ian considers the farm buildings important in his ambitions to improve earned income. He has plans to make this a centre for the wider rural community by providing a processing centre to add value to farm produce – in fact he would like to see it as a complete centre for the processing, distribution and sales of local farm produce. The general and local public are already interested in what the farm is doing turning up in high numbers to farm open days.

Flood management & planting trees
Soil health and water quality go hand in hand, but a natural flood management scheme at Honeydale has used innovative techniques to help reduce flooding from rapid storm run-off in the local village of Ascott-under-Wychwood. There is spring line on the farm, which feeds the Evenlode River via two main streams. The river rises and falls very quickly.In 2010 it flooded 60 homes in Ascott-under-Wychwood. All the land at Honeydale is on a slope and the streams had been straightened so water run off to the river was too efficient.

A new system was devised with the help of an aquatic consultant. The straightened stream was put back into its original sinuous bed still visible on the landscape and the water flow was held up further by the use of three ‘leaky’ dams. These are stone faced earth wall bunds with a leaky or permeable top, constructed from large stones, which are covered with turf to hide the landscape work. The water is then fed into a large scrape and wetland before reaching the Evenlode. This wetland area is planted up in a dense pattern with a mixture of hazels, willows and dogwoods to encourage water infiltration deep down into the soil. The net result is a flattening out of the peak water flow.

This scheme was supported by the Cotswold Rivers Trust and the Big Lottery Fund ‘Awards for All’ for capital works and tree planting. Not surprisingly, this scheme has attracted great interest from water companies and politicians.

Honey and pollination
To encourage diversity, the farm has recently installed seven beehives, with help and advice from Cotswold Bees. Not only will they provide income from honey sales, but they will also help pollinate seed crops and fruit trees. The first honey is from bees collecting nectar from a crop of Sainfoin; a long term crop used on the farm, which is down for 7-8 years and is very important as a soil improver.

Measurement and results
An experimental area on the farm has been invested in with monitoring equipment by North Wyke, Reading University and the Duchy College. The research focuses on the deep rooting mixtures important to the farm’s underlying philosophy, with interests in forage quality, nitrogen losses, and total emissions.

It’s still early days for the soil improvement measures so soil analyses are still base line references; soil organic matter measured by Loss on Ignition is at 4% sampled from soils in winter stubbles, potash levels are at a respectable 2 and phosphate levels quite high at 3 - certainly for the Cotswold brash soil type. As a control measure to compare against his present system, Ian has kept a total of 5 acres under the original ‘spring barley only’ system.

There are no additions from outside the farm system, either of purchased manures or composts – the manure from grazing sheep is the only, but very valuable input.

Early indicators
The advantages of the changes are already becoming evident – there is less sign of the soil erosion that used to build up in the farmyard and run down the drive. The grazing of the grass leys is effective in controlling troublesome weeds such as perennial sow thistle, which is grazed off before it gets chance to seed.

Permanent pasture is highly valued on the farm for its multiple benefits, so these have been preserved from the original farming system. They provide grazing in the shoulder months, a valuable hay crop and also native wild flowers, which are becoming rare in the countryside with the knock-on loss of their supporting role for our native insect pollinators.

The farm strives to be an example of how to produce food, care for wildlife, manage natural capital, maintain the landscape and protect human welfare; here, there are multiple outcomes from the same parcel of land. To quote Ian he hopes it to be ‘a new version of the mixed farm’.

 

Over the next few weeks we’ll be doing a bit of our own housekeeping too, in preparation for spring, cleaning out one of the hives that was recently donated to us. This involved blowtorching it to sterilize before the newly arrived colony is transferred into it in the Spring and the hive they are currently occupying will then be given a refurb too.

We’ll continue to check on the bees as winter progresses and we move towards spring.

This is in fact the second ring John had been asked to find on a farm. Earlier last year a local farmer lost his wedding ring during lambing and John was tasked with finding, not quite a needle in a haystack, but a ring in a big barn full of straw.
