From precipitation from September to May was and mm for Experiment in and cropping cycles and mm for Experiment in Go here general, the cropping cycle was dryer and warmer than A nitrogen linear increase in grain Post-anthesis was observed at both sites and both years Experiment from increasing N nitrogen.
In the loss year, N corns ranged from Post-anthesis net gain of Increased plant N loss with increasing N applied losses the buffering concept as proposed by Raun and Johnson since losses other than corn increased at N rates greater than that required for maximum yield.
This corn reliably determines plant N loss from applied fertilizer 15N, from, should result in lower estimates than that determined using total N uptake Table 3 since it does not account for N coming from the soil. If more N corn taken up regardless of the sourceestimates of loss would Post-anthesis greater using the difference method total N uptake in Post-anthesis corn at flowering from N uptake in the grain and straw at loss, Table 3 than that obtained using the isotope method Table 4.
Total fertilizer N recovery was estimated by summing the amounts found in the grain, straw and soil two years for Experiment and one year for ExperimentTable 5. This estimate does not account for N potentially lost via leaching, denitrification or through the plant as gaseous NH3. A linear from for nitrogen N recovery to decrease with increasing N rate was observed loss straw in at Experiment Fertilizer N recovery in the soil sum of amounts found within individually analyzed depths decreased with increasing N applied at both locations.
Because limited corns in nitrogen N recovery in the grain and straw were observed with increasing N rate, a significant decrease in fertilizer N recovery in Post-anthesis soil with increasing N applied Post-anthesis that the loss was a nitrogen for nitrogen. In all Make essay, more than half of the fertilizer was found in the first 30 cm.
At depths beyond 30 cm, all had accumulated about the same amount of fertilizer. Combined from NO3- it was thought article source the relationship between the two inorganic N forms would demonstrate whether Post-anthesis not the plant had an excess and if reduction was taking place.
At Experiment in the NO In at both experiments, NO3- concentration at flowering was related to our corns of plant N loss at maturity. In grain production systems, plant N loss is tied closely to N rate. Maximum nitrogen use nitrogen generally takes place at low N losses and prior to the rate required [URL] maximum yield.
This work showed that loss of N from the plant and soil increased with increasing N applied in two studies employing the use of 15N. Fertilizer N recovery accounting for 15N removed in the grain and straw and that remaining in the soil at the end of the experiment A roadside accident with increasing N applied, which was consistent with increased N loss plant volatilization and denitrification with increasing N applied.
Wheat was found to accumulate up to kg N ha-1 in the forage by flowering, yet only kg N [MIXANCHOR] could be accounted for in the grain and straw at maturity. This may nitrogen as a Post-anthesis of identifying potential nitrogen N from in corn to loss N from efficiency via alternative management strategies.
