Uniform Root Layer Application at Optimal Timing Can Effectively Improve Root-Knot Nematode Disease Control in Rui Yam

Agriculture, 2022
Root-knot nematode disease seriously threatens the production of Rui yams, making it important to explore effective management strategies, including the optimal time for disease control and efficient application techniques.

How Does Irrigation with Wastewater Affect the Physical Soil Properties and the Root Growth of Sugarcane under Subsurface Drip?

Agronomy
Studies on the development of the root system can provide important information about responses to different management strategies, such as the use of lower quality water, also evaluating the interaction between plants and the physical properties of the ...

A Generalization of Metropolis and Heat-Bath Sampling for Monte Carlo Simulations

, 1999
For a wide class of applications of the Monte Carlo method, we describe a general sampling methodology that is guaranteed to converge to a specified equilibrium distribution function. The method is distinct from that of Metropolis in that it is sometimes

Sampling Studies in Morning Glory Roots [PDF]

, 1941
Farmers and agriculturalists have in recent years become more conscious of the seriousness of the weed problems. The solution of this problem is obviously the development of more efficient and less costly methods of eradication. Most pernicious weeds are propagated vegetatively by means of underground parts in which reserve food is stored as a source ...

Higher order scrambled digital nets achieve the optimal rate of the root mean square error for smooth integrands

, 2012
We study a random sampling technique to approximate integrals $\int_{[0,1]^s}f(\mathbf{x})\,\mathrm{d}\mathbf{x}$ by averaging the function at some sampling points.

Carbon storage in old hedgerows: The importance of below‐ground biomass

GCB Bioenergy
Ambitious climate change mitigation goals require novel carbon (C) sinks in agricultural systems. Thus, the establishment of new hedgerows is increasingly attracting attention as a C sequestration measure.

Effect of riparian vegetation roots on development of meander bends in Tarim River, Northwest China

E3S Web of Conferences, 2018
Meandering channel with distorted bends develops along the Tarim River, the longest dryland river in China. The river bank and bed is majorly composed of coarse silt and fine sand and almost none clay content, making the bank strength very low.

Functionally-explicit sampling can answer key questions about the specificity of plant–microbe interactions

Environmental Microbiome, 2022
The rhizosphere is a nexus for plant–microbe interactions and, as a host-structured environment, a location of high activity for distinct microbes and plant species.
