We dug sods of pasture and Brendan was able to show how the humus had gone down over 2 inches where there was practically none 18 months ago. One paddock had been laser graded when he purchased the farm 3 years ago and was "pounded" with high analysis super, but the grass did not respond at all. The change since using Vitec fish has been dramatic. Brendan applies about 15 litres of fish to the hectare over the season with a low rate of urea ( 3 — 5 kg/Ha ). His pastures are lush, he had no bloat last season and only 2 cows had milk fever.
