Vegetable map made real

Since its publication on these pages in 2017 the Vegetable Map of Scotland [1] has attracted much interest. There is a growing awareness of the benefits of local, nutritious food – especially if bought from short supply chains that use the least possible carbon.

People want to know where their food comes from, how much is imported and how much grown locally and whether the country can grow more of its food within or near its borders.

These questions are asked especially of vegetables, including pulses and potato, because they are (or should be) mostly eaten very fresh, such as leaf, or else, like carrot and swede, kept not too long on the shelf before being cooked.

With this background of interest, the Vegetable Map was constructed by researchers at the Institute as part of joint interests with Nourish Scotland [2]. The group interrogated EU databases provided by the Scottish Government [3] to locate the fields in which the various vegetables and soft fruits were grown.

An example of part of the region is shown above. The Map remained available through this web site, then in late 2018, ideas began to form about making the map real – complete with vegetables – and it would be constructed in the Living Field garden [4].

Tayside’s neolithic?

Time went by. Ground was weeded, cleared and cultivated – a rare barrenness in the otherwise plant-rich garden. Then gradually, over the winter, tectonic plates shifted.

People began to wonder about the strange earthworks dotted with rocks that appeared in the plot. Was the garden being visited at night by strange forces or was the Living Field community finally just losing it? Rumours were rife.

Rocks laid in formation and the ground smoothed again

More time went by. Turf was laid in a great rectangle over the whole patch, but people were still unclear of what it was all for …. and what lay underneath.

The turf rooted and formed a fine carpet. But what were the rocks? A ritual landscape? Tayside’s answer to the Ring of Brodgar?

The laying of the turf, before the winter 2018/19

Then one day in late spring 2019 an outline was traced and the turf was cut to reveal the unmistakable shape of ….. Scotland ….. its indented coast now clear and the land inside complete with hills and mountains.

All well so far ……. a map of the country covered in grass and rocks …… nothing new there. But then in May, holes were cut in the turf and plants put in the holes: and you’ll guess what plants – Yes, vegetables.

The map complete, ready for the vegetables in spring 2019

And that is where we are at the beginning of June 2019. The Farm’s drone was flown to photograph the Living Field garden from the air on 5 June. The image of the map appears below.

Different types of vegetable are being planted in the parts of the country where they are typically grown. It is possible to see the early plantings to the right of the image. The brown holes in the turf are where circles have been cut in readiness for later plantings. (The ‘corners’ and lower border are spare turf in case of need.)

Planting will continue well into the summer. There will be some surprises which we shall show later.

For now, you can read more about the history of vegetable growing at the original page [1]. photographs of the construction will follow – link to be provided. And there will be more articles on what can and can’t be grown in the soils and climates of our northern latitudes.

Living Field people will be on hand at Open Farm Sunday 9 June 2019 to explain more about the Vegetable Map of Scotland. See you there!

With apologies to the Outer Hebrides, Orkney and Shetland, presently missing from the map but to be included.

Together, and with other coopted helpers they measured out the grid, made the mountains (like Titans), laid and cut the turf and raised and planted the plants. A great effort by the Living Field community!

Mashlum no more! Not yet

The mixed cereal-pulse crop known as mashlum. Decline after 1950 yet still grown in a few fields. The question of crop mixtures in prehistory.

An earlier article Mashlum – a traditional mix of oats and beans [1] suggested that the mixed cereal and pulse crop known as mashlum had died out in Scotland but no ….. an email from a farmer in Fife, Douglas Christie, confirmed that it was still grown on his farm. Here is a photograph.

Earlier we had related an account from 1925 [2] on the difficulties of growing mashlum and also the benefits. Mr Christie reports that the mixture worked very well, that chemical and nitrogen fertilizer costs were drastically reduced, but that he had to pick the field carefully as some weeds would be difficult to control.

He also overcame some of the problems in sowing and harvesting a mixture reported in earlier accounts from the 1920s. He has a drill  that can sow (direct drill) the two crops at the same time and a grain dresser that can easily separate the two crops after harvest,

Since hearing from Douglas Christie, the Living Field has noticed on Twitter that several farmers in the south of the UK are also working with mixed cereal-pulse crops. A further question arose in correspondence as to their antiquity.

Mashlum in the crop census

That mashlum merited a separate chapter in the 1925 Farm Crops [2] shows how seriously it was taken. It first appeared in the agricultural census [3] under the heading ‘vetches, tares, beans, mashlum for fodder’ between 1902 and 1919. The category in the census then changed slightly to ‘vetches and mashlum for threshing’ which declined to a low point in 1939 (grey symbols in Fig. 1). Presumably the need for fixed nitrogen during shortages caused vetches and mashlum to increase in area almost 10 times during the war years.

Most of this increase was in mashlum, which in the 1940s and early 1950s became the most widely grown legume crop in Scotland – covering more area than beans and peas – and was listed in the census simply as ‘mashlum for threshing’ (orange symbols in Fig. 1) , that is, grown and harvested for seed.   After a few years, it declined again in the early 1950s and had almost died out by 1960. In 1961, mashlum disappeared from the census and any remaining fields were combined with ‘other crops for stockfeeding’ (green symbols to the right of the trace in Fig. 1).

Fig. 1 The area sown with mashlum and related crops in the agricultural census in Scotland, 1902-1978 [3]. Mashlum was listed as a separate item in the crop census from 1944 to 1960 (orange). Before that it was part of ‘vetches, tares, etc.’ up to 1919 (light blue-grey), then vetches and mashlum for threshing (grey). Any crops remaining after 1960 were counted as part of ‘other crops for stockfeeding’ (green symbols).

The period from the late 1950s to the 1980s was the time of rapid increase in the use of mineral nitrogen fertiliser.  The cereal-pulse mix became uneconomical.

Despite its temporary revival in the 1940s, mashlum, as all other legume crops, was grown on a small part of the arable surface in the 20th century, generally less than 1% of it.

Cereal-pulse mixtures in prehistory?

A question then arises as to how old is the practice of sowing mixed  cereals and pulses. The Dictionary of the Older Scottish Tongue (DOST) finds that mashlum, in the spelling mashloche, was in use more than 500 years ago [4], but that in itself tells little of the crop’s ancestry. Was the method handed down from earlier Bronze or Iron Age  farmers to the medieval period or was it brought over by the Romans or early Christians?

The archaeological record in the north of Britain is thin on peas and beans: there is one record of field beans in Scotland  – also known as horse bean and Celtic bean, now faba bean.  Peas and beans appear far less frequently than cereal grains, but this difference is often attributed to the methods of cooking them: beans are less likely than grain to be charred and hence preserved. In an authoritative survey beans and cereals were examined in 75 locations in southern England [5].

At some archaeological sites, beans and cereals, such as emmer wheat, are found together and in numbers that suggest they were both grown as crops for food. Descriptions of the finds at Foster’s Field, Sherborne in Dorset  for example, include the line that beans ‘may have been grown as a mixed crop with barley or as part of a crop rotation system’ [6], a statement repeated in the broader survey [5].

The archaeologists agree that presence itself does not mean anything definitive about how the crops were grown – whether alone, in broadcast mixtures, or in rotation or sequence. It is not hard to imagine, though, that cereal-pulse mixtures have been used from the earliest times. Imagine a household or village had some cereal and some legume seed, not enough to be sown alone, but together they would make a field.

And the same farmers would have known, as all farmers up to the mid-1950s have known, that cereal and pulses together do better on poor soil than cereals alone because of the nitrogen-fixing ability of the pulses, and if the pulse is faba bean, then also the support offered by the stronger bean stem.

Common sense tells that they would have grown mixtures but there is no definitive evidence.

Feel the pulse

With Dundee Science Centre, the James Hutton Institute is  contributing to a range of outreach activities in 2016 as part of The Crunch, and initiative headed by the UK-wide Association of Science and Discovery Centres and supported by the Wellcome trust.

Our exhibit at a community-run event in Baxter Park Dundee on 28 July 2016 was called – Feel the Pulse – a display of beans and peas, which along with lentils are known as ‘pulses’ (images below).


Why pulses? They yield a highly nutritious, plant protein that can be grown without nitrogen fertiliser because the plants themselves fix nitrogen gas from the air into their own bodies. Nitrogen is essential for plant growth, but in its mineral form (from bags of fertiliser) can be a serious pollutant, contaminating streams and drinking water.

Once, peas and beans were widely grown and eaten, but the arrival of industrially made nitrogen fertiliser about 100 years ago and the ready import of plant protein from other countries caused pulses to decline as crops.


Yet today, pulses are widely acclaimed for their benefits to health and the environment. The field bean Vicia faba crops above were grown locally without nitrogen fertiliser. They also offered a habitat and refuge for insects and small animals.

Is there a way to turn the tide – to farm more locally-grown cereal and legume produce, use less mineral N and support a cleaner environment.

We believe there is but one of the first things to do is to increase awareness of the benefits of peas and beans and similar products.


Our exhibit – Feel the Pulse – shows some of the things that are being done, such as finding types of peas and beans suited to the local conditions, comparing the nutritional value of different pulses and finding new pulse-based products for the market, for example bean bread and bean beer, both made from field bean flour.
