Preliminary Studies on Depth of Soil Moisture Extraction by Sugarcane Using the Neutron Probe

چکیده
The design and operation of supplementary irrigation schemes are dependent upon an accurate estimation of the "total available moisture" in the soil. This has been defined as the amount of water held between the limits of field capacity and wilting point in the effective rooting depth of the crop. Under irrigated conditions the effective rooting depth is that depth of soil from which the crop can remove all of the available moisture before its growth is materially affected, and is determined in the field by visual inspection of the soil profile and the crop rooting habits.

Measurement depth of the cosmic ray soil moisture probe affected by hydrogen from various sources
[1] We present here a simple and robust framework for quantifying the effective sensor depth of cosmic ray soil moisture neutron probes such that reliable water fluxes may be computed from a time series of cosmic ray soil moisture. In particular, we describe how the neutron signal depends on three near-surface hydrogen sources: surface water, soil moisture, and lattice water (water in minerals ...
متن کاملLarge Area Soil Moisture Measurement Using Cosmic Rays Neutrons: The Australian CosmOz Network
Field measurement of soil moisture is undertaken traditionally using point based measurement techniques such as neutron probes or time domain reflectrometry (TDR). Recently, a new technique has been developed that can be used to derive soil moisture at larger spatial scales by measuring neutrons that are generated by cosmic rays within the air and soil, and emitted back into the atmosphere. A ...
متن کاملThe COsmic-ray Soil Moisture Interaction Code (COSMIC) for use in data assimilation
Soil moisture status in land surface models (LSMs) can be updated by assimilating cosmic-ray neutron intensity measured in air above the surface. This requires a fast and accurate model to calculate the neutron intensity from the profiles of soil moisture modeled by the LSM. The existing Monte Carlo N-Particle eXtended (MCNPX) model is sufficiently accurate but too slow to be practical in the c...

متن کاملProduction of Single Cell Protein from Sugarcane Bagasse by Saccharomyces cerevisiae in Tray Bioreactor
In this study, solid state fermentation (SSF) was carried out to produce single cell protein (SCP) from sugarcane bagasse using Saccharomyces cerevisiae. The SSF experiment were performed in a tray bioreactor. The influence of several parameters including extraction buffer, initial moisture content of substrate, fermentation time, relative humidity in bioreactor, the bioreactor temperature and ...
