The physical characteristics and spatial location of
land are hypothesized to be significant inputs to its
valuation. This research evaluates the influence of
locational, economic, and physical site variables on the
assessed value of real property.
Evaluation of such influences is based on a stratified
systematic sample of land parcels...
The National Agricultural Statistical Service (NASS) conducts quarterly surveys for estimation of some primary commodities produced on farms and ranches. The commodities often have highly skewed distributions with a few farms producing very large amounts. NASS uses dual sampling frames comprised of the list frame for efficient stratification and the...
A method of calculating surface evapotranspiration by separately
including the effects of vegetation and atmospheric evaporative demand
under the condition of nonlimiting soil moisture is presented. A
literature survey is conducted to determine the effects of plants on
evapotranspiration.
To represent the atmospheric evaporative demand, the original
potential evaporation equation...
The vast area of sandy soils in Thailand which are low in fertility
and can hardly hold water, prompted this investigation. A greenhouse
study was conducted from December 1978 to April 1980 to find out
the effect of straw on nitrogen availability that could affect dry
matter yield and nitrogen...
The Petchburi Irrigation Project was built in the southern part of
the Central Plain of Thailand in 1942. The purpose of the project was
to divert water from the Petchburi River to irrigate the principal part
of the Petchburi Plain where lands were used for rice and upland crop
production....
The investigations were based on a complete diallel cross
among three inbred lines of Suffolk sheep. Line of sire effects were
assumed to be an estimate of general combining ability effects while
sire x dam interaction was assumed to be an estimate of specific
combining ability. The line of dam...
The economic efficiency related to the use of the range resource
is extremely important to an area such as Southeastern Oregon where
most of the gross income of the area is obtained from range livestock
production; important to the economic progress of the region and to
the development of a...
The refractive index of particulate matter suspended in seawater
is nonuniform and potentially is an indicator of composition and
origin. A method is described for determining the refractive index
distribution. The method requires the measurement of the volume
scattering function and assumes the total size distribution to be
capable of...
