'We farm in one of the driest area in Wales. One of the things that we've learnt over the 20 years that we've been here is to try and predict and look out for a drought that's coming our way. The minute growth rate drops below what we would deem to be average for that time of year, and particularly if there's no rain in the forecast, then we would start putting things in place early, and that's the key thing because you can make a massive difference to the effect that drought has on your grassland.'
