Root orientation of four sorghum cultivars: application to estimate root length density from root counts in soil profiles [PDF]

Plant Root, 2008
The root length density (RLD) distri- bution in the soil is a key factor for water and nutrient uptake but its direct assessment is not easy. A field method is presented here to assess RLD of sorghum (Sorghum bicolor L. Moench) from the root intersection density (RID) and taking root orientations into account.

Compensation in Root Water Uptake Models Combined with Three‐Dimensional Root Length Density Distribution

Vadose Zone Journal, 2014
Because root water uptake is a considerable component in the soil water balance, a lot of attention has been paid to defining and applying root water uptake models. These models can be grouped into empirical vs. mechanistic root uptake models. Intermodel comparisons are valuable in understanding the different concepts used.

Wood Chip Incorporation in Almond Orchard Planting Berms Increased Gravimetric Water Content, Soil CO2 Efflux, and Fine Root Length Density

HortScience
Incorporation of chipped woody material into soil instead of burning or transporting wood chips (WCs) off-site is a practical solution to dispose of old orchard trees.

Different Responses in Root Water Uptake of Summer Maize to Planting Density and Nitrogen Fertilization [PDF]

, 2022
Modifying farming practices combined with breeding has the potential to improve water and nutrient use efficiency by regulating root growth, but achieving this goal requires phenotyping the roots, including their architecture and ability to take up water

In situ Root Phenotypes of Cotton Seedlings Under Phosphorus Stress Revealed Through RhizoPot

Frontiers in Plant Science, 2021
Phosphorus (P) deficiency is a common challenge in crop production because of its poor mobility through the soil. The root system plays a significant role in P absorption from the soil and is the initial indicator of low P levels. However, the phenotypic

Characterizing Root Morphological Traits in 65 Genotypes of Foxtail Millet (Setaria italica L.) from Four Different Ecological Regions in China

Agronomy, 2022
As an indispensable grain crop, foxtail millet (Setaria italica L.) is becoming a functional food in China because of its abundant nutrients. However, low rainfall and uneven precipitation limit its growth and production, especially in northwest China ...

Influence of Paulownia fortunei (Seem.) Hemsl. roots on preferential flow in the red soil hilly region

Soil and Water Research, 2023
Preferential water flow in soil significantly affects runoff, water infiltration, storage, groundwater environment, and soil stability. Plant roots positively affect preferential flow development.

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]

, 2009
We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A
