Spring Planting Farming Update

Posted: 13th July 2017

As part of our eight year rotation we sow certain areas of the farm each year with cash crops or fertility building leys.

Following our experiment last year with sowing fertility building leys together with a nurse crop of buckwheat, we’ve taken the same approach again. Buckwheat acts as a quick growing and leafy cover and while the ley establishes beneath it, the buckwheat helps to retain moisture and offers shelter from the summer sun. This is important on our south facing, free draining, dry soils. However, we’ve reduced the buckwheat to 10 kilos per acre this year as it was a bit too thick last year at 20 kilos per acre. The buckwheat was drilled to 1.5 cm and in a separate pass, the ley mix was broadcast and harrowed with a consolidating flat roller to finish.

We also established cash crops. Spring wheat was sown at the end of April, undersown with yellow trefoil and white clover to improve fertility and provide grazing once the crop is combined in the autumn. It’s going to be interesting to see whether this has established after slow stunted growth due to lack of rain.

The other cash crop we’ve grown is spring oats. We originally experimented with direct drilling into last year’s yellow trefoil and white clover that was left in place over the winter. The yellow trefoil and white clover was grazed tightly and oats direct drilled with the Aitchison drill at a rate of 250 kilos per hectare in mid April. But the lack of rain has caused havoc. With a year‘s growth under its belt the deep rooting and drought tolerant yellow trefoil and white clover grew back far more strongly than anticipated and swamped out the oats. So several weeks later, and with only a handful of gallant oat plants soldiering on, the decision was taken to plough the field and resow from scratch. The oats are now looking great.

Ryegrass and vetch was sown last autumn, direct drilled into last year’s oats stubble. It provided useful early grazing this spring for sheep. It was ploughed in March and a field scale bird food mixture was established. The dry weather has again taken its toll and the crop is thin. Weeds are present and we are going to decide if we leave the crop in or sow again. Much depends on how much rain is in the forecast.

As part of our ongoing experimentation, we have left four acres of spring barley unchanged since we took over the farm, providing two continuous control plots that let us compare the effect that the new rotational system, with its associated soil improving species and no artificial inputs has on soil health, compared to a high input continuous cereal system.

This is also the first year that we’ll be able to look at the relative costs between the 8 year rotation and the high input, conventionally grown spring barley, which has received standard treatments of fungicides, herbicides and nitrogen.

The wildflower margins are in their third year, running in 12 metre strips around each field. We are seeing a noticeable change in the balance of species present, from early pioneer species in the first couple of years, such as oxeye daisy and wild carrot, to the species that have taken longer to establish, like field scabious, musk mallow and meadow buttercup. They are creating a great habitat for pollinators, insects, hares and ground nesting bird species.

About Us

It's always been part of our vision to have a farm as an extension of the Cotswold Seeds business and in 2013 we bought Honeydale Farm, one hundred acres in the Cotswolds. During the past couple of years we've been making huge progress on the farm and this blog was set up to share this progress with our friends in the farming world.
