The location and persistence of ammonia (aqueous, anhydrous and anhydrous + ‘N-serve’) injected into a sandy loam soil, as shown by changes in concentrations of ammonium and nitrate ionsThe Journal of Agricultural Science, 85
This study was conducted to elucidate the crop physiological basis for yield differences frequently observed in experiments comparing top‐dressing of N fertilizers with injection of ammonium or ammonium/urea solutions into the soil. The effects of diammonium phosphate (NH4‐N) injected at the two‐leaf stage, calcium nitrate (NO3‐N) broadcasted and incorporated before sowing, and a control without N fertilization (‐N) were assessed from measurements of growth, N‐uptake and N‐partitioning, light interception, gas exchange, leaf anatomy and the activity of key enzymes of N‐metabolism. The experiment was performed with spring barley (Hordeum vulgare L.) grown in 80‐l containers in a vegetation hall in Braunschweig, Germany. The plants in the NH4‐N treatment produced a 20 % higher grain yield than those in the NO3‐N treatment. The grain yield superiority of the NH4‐N plants was attributable to a higher number of ears per plant (+13 %) and more grains per ear (+6 %). The NH4‐N plants exhibited lower concentrations of inorganic cations than plants supplied with NO3‐N. In the NH4‐N treatment, the light penetrated more deeply into the crop canopy and the NH4‐N plants exhibited a higher leaf carbon exchange rate at the different leaf layers than the NO3‐N plants. It is concluded that as opposed to predominantly nitrate nutrition, provision of a persistent source of ammonium enables plants to take advantage of the positive yield effect of mixed N nutrition.
