Fine Root Growth Response to Soil-Applied Nitrogen and Paclobutrazol
Practices to promote tree root growth have been sought in arboriculture for many years, especially as a treatment for trees that are stressed or in decline. Tree fertilization is a common practice in arboriculture. A few research reports have shown that nitrogen fertilization can increase fine-root density in localized areas of soil where the fertilizer has been applied, but the effect on the w...
متن کاملStimulated fine root growth benefits maize nutrient uptake under optimized nitrogen management
Optimized nitrogen (N) management reduces total N application without sacrificing cropyield. However, the underlining mechanisms have not been well investigated, especially lackingthe evidence from roots. Here we performed a two-year field experiment with maize grownunder zero-N, conventional N and optimized N applications and examined grain yield, N,phosphorous (P) and potassium (K) uptake and...
متن کاملMaize response to water, salinity and nitrogen levels: soil and plant ions accumulation
In the present study, some nutritional imbalances, specific ion toxicity and yield-ion concentration relationships in maize under water, nitrogen (N) and salinity stresses were assessed. Effect of different levels of irrigation water (I1=1.0ETc+0.25ETc as leaching, I2 =0.75I1 and I3 =0.5I1) as main plot, salinity of irrigation water (S1=0.6, S2= 2.0 and S3=4.0 dS m-1) as sub-plot and N fertiliz...
متن کاملFine root growth dynamics of four Mojave Desert shrubs as related to soil moisture and microsite
Water is generally considered to be the major limiting factor for perennial shrub growth in the Mojave Desert, USA. However, the responses of active fine roots to soil moisture and microsite differed among Ambrosia dumosa, Ephedra nevadensis, Larrea tridentata, and Lycium pallidum, suggesting differences in root foraging strategies. Ambrosia and Ephedra had a positive linear relationship betwee...
متن کاملA global analysis of fine root production as affected by soil nitrogen and phosphorus.
Fine root production is the largest component of belowground production and plays substantial roles in the biogeochemical cycles of terrestrial ecosystems. The increasing availability of nitrogen (N) and phosphorus (P) due to human activities is expected to increase aboveground net primary production (ANNP), but the response of fine root production to N and P remains unclear. If roots respond t...
