[QUOTE="Agriland RSS, post: 8114281, member: 105608"] Written by Justin Roberts from Agriland Silage production in Ireland has always centred on grass, but should other plant species, such as clover, be more regularly incorporated into swards, then we may need to assess how the crop is handled in the field. When clover makes a up significant part of the sward then two more factors need to be given far greater consideration by manufacturers of grassland equipment than hitherto, these are are [B]crop hygiene[/B] and [B]leaf loss[/B]. [HEADING=1]The emergence of mergers[/HEADING] With the advent of larger tractors able to drive wider mowers followed by ever more powerful forage harvesters, swathes have naturally gotten bigger. Yet this comes at the risk of greater contamination and leaf shatter as the cut crop has to be dragged across greater distances by increasingly wider rakes, according to the makers of crop mergers, or belt rakes, as they are also referred to.

Instead, the material is picked up off the ground and placed on a belt which then moves it to either the left or the right, or even the centre on twin belt machines. [HEADING=1]Developed in warmer climates[/HEADING] Essentially they are groupers fed from a pick-up reel rather than mower blades and conditioner, and just like mowers, they may be trailed or mounted.

Alfalfa is another leafy legume that is nowhere near as robust as grass and so needs careful handling. Belt rakes have therefore been mainly sold where this is an important forage crop, the U.S and southern Europe especially. [HEADING=1]Clover needs careful handling[/HEADING] Yet now that farmers in Ireland are being encouraged to grow more clover and other species within a sward the importance of leaf shatter as a leading loss of nutrients will increase. The view that mergers are not really relevant to more temperate climates may be changing as two companies that are very much grassland orientated have suddenly developed an interest in the concept.

[HEADING=1]Italian connection[/HEADING] The first to start doing so was Kverneland which purchased an 80% stake in ROC of Italy last October. ROC was formed in 1996 to produce equipment "for forage dehydration plants, biomass and biogas plants as well as big farms specialising in hay, silage and straw production," according to the company itself. [URL='https://cdn.agriland.ie/uploads/2022/04/IMG_01111-1500x1000-1.jpg'][IMG alt="ROC belt rake for alfalfa"]https://cdn.agriland.ie/uploads/2022/04/IMG_01111-1500x1000-1-1024x640.jpg[/IMG][/URL] The ROC RT 1220 is the largest merger in the company's range Today it offers a multitude of mounted and trailed units up to a 12-metre model. Kuhn, which already services the U.S market, lists a 12.8m machine on its site, so working widths are not far short of rotary rakes. However, these are somewhat smaller than Kverneland's present largest conventional rake, the 15m wide 97 150C. [HEADING=1]Passive transport[/HEADING] The great advantage that belt rakes offer is that they pick up the crop and transport across the width of the machine rather than drag it across the ground. A large four-rotor conventional rake moves the crop up to 7m across the surface with the outer part passing through two rotors. [URL='https://cdn.agriland.ie/uploads/2022/04/IMG_6234_-1500x1000-1.jpg'][IMG alt="tine pick on ROC merger"]https://cdn.agriland.ie/uploads/2022/04/IMG_6234_-1500x1000-1-1024x640.jpg[/IMG][/URL] Slower moving tines on a pick-up reel cause less damage to the crop claim the manufacturers The larger the rotors, the greater the tine speed and so the more likely it is that the crop will be damaged during movement. The lower tine speed of a pick-up real is said to greatly reduce this problem. [URL='https://www.agriland.ie/farming-news/kverneland-buys-into-italian-roc-company/']ROC[/URL] also notes that because the crop is handled far more gently it may be handled more often without suffering dramatic leaf loss. Thus, in thin or short crops, a swath may be moved a second time to combine it with another, and so reduces the passes required by the harvester without the leaf shatter associated with a normal rake. [HEADING=1]Keep it clean for clover[/HEADING] The potential for damage to the crop and contamination by stones, soil and faeces is much greater with a standard tined rake, and this is the second big selling point for belt mergers. Pottinger, the latest company to introduce a belt rake to its range, has long been keen on promoting the importance of a clean sward to ensure proper fermentation. [URL='https://cdn.agriland.ie/uploads/2022/04/Verschiedene-Erntegu%CC%88ter-Luzerneheu-1.jpg'][IMG alt="Silage with clover is helped by belt rakes"]https://cdn.agriland.ie/uploads/2022/04/Verschiedene-Erntegu%CC%88ter-Luzerneheu-1.jpg[/IMG][/URL] A clean lift with a real reduces contamination Dirt and soil can introduce clostridia and other detrimental bacteria to the the silage which slows down fermentation and leads to a loss of nutrients in the pit or bale.

[HEADING=1]Moving on from monocrop grass[/HEADING] To what extent belt rakes or mergers will take a hold in Ireland, if at all, will probably depend more on the size of the shift to clover rich swards than any other factor. Clover rich swards are more prone to butyric fermentation as the nitrogen compounds within them act as buffering agents and so reduce the rate of healthy fermentation. Keeping them free of dirt becomes more important as clover content increases. It is also claimed that belt rakes are better able to cope with wet and boggy ground and are not as power hungry as rotary type rakes.
