Effect of Nitrogen Fertilization on the Chemical Composition of Bromegrass¹

Nitrate accumulation in smooth bromegrass as influenced by applied fertilizer and environmental conditions

“…Campbell (1924) found this was true with Amaranthus retroflexus L., a weed species which has often been quoted as accu mulating large quantities of nitrate. Similar results have been found with oats (Smith, I960) and bromegrass (Carey et al, 1952). Olson and Whitehead (1940) sampled various weeds from bud stage to maturity and found a consistent decrease in nitrate content.…”

“…calcium-phosphorus ratio, pore size distribution, and surface area (2,6,9)-as well as estimation of the relative reactivity itself by known techniques: measurement of phosphorus solubility in solutions of neutral ammonium citrate, citric acid, and phosphoric acid (3, 8 ) . calcium-phosphorus ratio, pore size distribution, and surface area (2,6,9)-as well as estimation of the relative reactivity itself by known techniques: measurement of phosphorus solubility in solutions of neutral ammonium citrate, citric acid, and phosphoric acid (3, 8 ) .…”

“…Mitchell, and Anderson (2) found that the nitrate content of bromegrass increased markedly with increasing rates of application of NHI-NO3 fertilizer. Some data are available for perennial forage grasses.…”

Nitrogen Fertilization and Cutting Management of Sudangrasses and Millets1

“…It has been shown that applying nitrogen fertilizer to pure stands of grass has increased yields of grasses on most soils. Generally, these increased yields have been accompanied by increases in percent protein in the herbage ( 1,4,5,10). Occasionally, when the nitrogen fertilization rates have been low, little or no increase in protein percentages has been obtained ( 3).…”
