摘要: This study investigated how repeated applications of different types anaerobic digestates and undigested cattle slurry affected the growth responses nutritional aspects ryegrass swards (Lolium perenne L.) soil nutrient concentrations, in a two-season field trial. The treatments included four digestate, slurry, nitrogen control (N-control) with calcium ammonium nitrate (CAN) no fertiliser control, distributed randomised block design three replicates. biofertilisers drove comparable average forage daily rate varying between 65 79 kg ha???1 day???1 (p???>???0.05). Crude protein neutral or acid detergent fibre were not influenced by any type biofertiliser Most led to increases level available P K (p?????0.05). Despite detectable influence levels NPK on plant responses, when applied using same dry matter amounts can drive grass low over quality forage. Repeated help increase reduce losses K. application N content soil; however, there differences them, despite their considerable terms inputs. might be linked volatility readily from applied.
