|Ewes Grazing Cover Crops|
|Soil Structure After Sheep Grazing|
The sheep have a done a great job grazing off the rye and vetch on the hill and soon they will be split up into their grazing groups ready for lambing and its back onto the grassland then. The use of cover crops has some many wider benefits as well as reducing costs in the farming system system. Under this stone on the headland I discovered a fantastic population of Carabid (Ground) Beetles all waiting to pounce on any unsuspecting prey. There are over 350 species in the UK, does anyone know what these ones are? The adults and larvae will feed on other invertebrates, slugs, snails and carrion. Some smaller species will also feed on aphids, so they could be a very helpful ally in the season ahead.

|Catchment Sensitive Farmers Meeting|
It seems that the worst leaching occurs after Oilseed Rape and Wheat, probably due to the higher levels of fertiliser they receive but also due to the very inefficient way these plants use the applied nitrogen. Wheat for example is only about 60% efficient when looking at applied or synthetic nitrogen fertiliser. Where cover crops are used the leached level of nitrogen is about 50% that of land farmed without cover crops. This has a significant impact when looking at the catchment as a whole. It is great credit to Wessex Water that they have decided to take this partnership approach to try and reduce diffuse pollution working together with the farmers in the catchment.

The session continued in the local village hall with a great presentation on 'Making the Most of Cover Crops' by Ian from Oakbank. Ian talked about different cover crop mixes, how and when to establish them, and the merits of diverse mixes and the impact of this type of farming can have to the on the bottom line and the better environment. A great day of learning.

|Red Poll Cattle Grazing Old Grassland|
The grassland has become quite old and matted so a change in grazing technique was required. As we have cattle of our own we have very kindly adopted, for a few weeks, some young heifers from the Kemerton pedigree Red Poll herd. Their job is to eat the standing grass, which as this time of year is like a hay crop, and tread in the inedible bits. All of these hooves will push the uneaten old and dead grass into the soil where the biology (bacteria and fungi) will start to break down the material and recycle the nutrients.
Over time this will improve the quality of the grassland enabling wider species to be introduced. The cattle are being fed hay, which we made back in July, from the species rich tower field with the hope that these ancient species will be moved across to improve the diversity of the sward in the neighbouring fields. The cattle will be socked quite tightly to make sure they eat the right amount of grass and moved on accordingly, always with a supply of hay nearby.
It's a great example of how farmers can work together to get the best results for all parties. These cattle are traditional breeds and will be very happy on the hill whatever the British climate will throw at them.

|Wheat Drilled into Oat Stubbles|
I think this could have possibly been one of the best autumns for establishing winter crops I can remember for quite some time. After the very dry summer months we started to get rain at just about the right time. This rain enabled weeds to germinate in the stubble's and cover crops before the main crops were planted. We had enough rain over the planting period to make sure that the seeds we planted germinated rapidly and emerged very quickly.
This year we have only used seed dressings with Zinc and Manganese on them to kick start the growth of the young plants, except on 1 block of barley we are growing for seed. Every year we have tested leaves for deficiency and these trace elements have always come up short.
One dilemma I have had is whether or not we should be spraying an autumn insecticide to control aphids. The aphids (Bird Cherry-Oat and Grain Aphids) could be carrying a virus called Barley Yellow Dwarf Virus which stunts the growth of plants and reduces yield. The only problem is you don't know if the aphids in our crops are carrying the virus and if the plants have been infected until the spring, when its too late to treat. The AHDB has developed a tool to assess when you should spray for aphids. This can play a crucial role when we are using Integrated Pest Management to responsibly use pesticides. This means that when we see a pest, we monitor its development and then spray with the correct product, with the correct amount of water and the correct dose rate to take the pest out. The tool can be found HERE
As we are trying to reduce the levels of insecticide we apply on our fields I have decided not to spray half of the wheat area that was later planted but rely on our beneficial predators to help reduce the numbers of aphids. There are always lots of spiders webs across the fields and the aphids should provide a tasty snack! The Game and Wildlife Conservation Trust did some research which indicated that the effect on beneficial insects of that autumn spray was still apparent the following June.
Providing grassy margins around our field boundaries and beetle banks within larger fields also help create habitat for beneficial insects to live ready to strike at invading aphids. We will see in the spring whether or not this was a good decision! We need a good hard winter to help kill off as many aphids as possible.
