David Thomas
Farm Manager
In the video below/above, David, with input from Ellis Luckhurst (agronomist and technical manager for Riviera Produce Ltd) talk about:
- Pest, disease and weed control
- Strip tilling to improve soil structure and moisture retention and give a much more even crop (describing what the strip tiller is and how it works...)
- Selecting disease resistant varieties that will give good quality and high yielding crops
- Using cover crops to improve soil structure, biodiversity, nutrient management, and pest control through increasing the amount and variety of beneficial insects. David and Ellis describe some of the key benefits and considerations for cover crop management.
- They are working towards growing more and more disease resistant crop varieties, trying to select those that are of good supermarket quality and give high yields but also looking for tolerance to leaf disease.
- They are greatly reducing their herbicide use (they've grown all winter cauliflowers and spring greens this year without the use of residual herbicides), and are increasingly using more mechanical methods and inter row cultivation; strip tilling to create better soil drainage, reduce compaction, and more even crops (GPS system is used to line up planters with the strips).
- They have been growing cover crop mixtures such as phacelia, linseed and clover for the last 3 years. Typically, after cauliflowers have been harvested in July, a cover crop will be lightly disced in, left over the winter then planted in the spring again. They no longer plough; after lightly discing, a Vaderstad CrossCutter breaks up all the dead material, then they run a strip tiller through and start planting behind it.
- They have noticed a big increase in soil biota and beneficials such as hoverflies, ladybirds and bees since doing strip tilling and growing cover crops.
