PUBLIC LAND POLICY AND THE VALUE OF GRAZING PERMITS

This article provides an empirical test of the traditional theory of permit value and investigates the impact of recent changes in public land policies on the value of grazing permits. Results suggest that the cost advantage for grazing on public lands has been capitalized into substantial permit values, but other economic and hedonic factors influencing land prices also have contributed to the value of grazing permits. Public land grazing permits have fallen in value relative to deeded land as grazing fees have increased and as assurance has waned that public land policies will continue to be favorable to ranchers.Land Economics/Use,

Fertilizer production functions for corn and oats; Including an analysis of irrigated and residual response

This study includes predictions of fertilizer production functions for four experiments. The experiments on Clarion and McPaul soils contain predictions of total and marginal yields, isoquants and marginal rates of substitution, isoclines and economic optima. Similar analyses for the other two experiments, conducted on Carrington soil during successive growing seasons, were not warranted because insufficient rainfall limited yield responses. The experiments included in this study were based on partially replicated factorial designs. The experiment with corn on Clarion silt loam in 1954 included nitrogen, phosphorus and potash as variable nutrients. The production function, isoquants and isoclines are represented by equations a, b, c, d, e, f and g. In these equations (and equations listed below), N, P and K denote the pounds per acre of nitrogen, P2O5 and K20, respectively. Isoquant and isocline equations were derived for each pair of nutrients. Hence, there are three of each of these equations. The α in the isocline equations represents a constant price or substitution ratio

Production surfaces and economic optima for corn yields with respect to stand and nitrogen levels

This study presents production functions for three experiments on corn in Iowa. It is fourth in a series of studies designed to derive corn response surfaces, yield isoquants and economic optima in fertilizer use.:! It differs from previous studies in that, for the first time, stand (plant population) is included as a variable input along with a plant nutrient (nitrogen). The analysis permits estimation of yield response to stand and to nitrogen as well as to the interaction between stand and nitrogen. Knowledge of this type is relevant, not only for farm recommendations, but also for improved planning of fertilization experiments. The first experiment reported involved stand levels on Shelby loam and was conducted in Ringgold County in 1956. The other two experiments reported were conducted in 1953, with variable stand and nitrogen levels on Marshall and Seymour silt loams, respectively, and were located in Fremont and Wayne counties.3 Each of these experiments included an early and an adapted variety of corn (Iowa 4297 or Iowa 4397 and A.E.S. 801, respectively)

Structural investigation of Fe silicide films grown by pulsed laser deposition

Pulsed laser deposition was used to grow epitaxial β‐FeSi2 films on Si(111) (1×1) and Si(111) (7×7) with the following epitaxial orientations: β‐FeSi2(001)//Si(111) with β‐FeSi2[010]//Si〈110〉 and three rotational variants. Silicide growth was influenced by substrate temperature and deposition rate, but not by the structure of the starting surface. Films containing both β‐FeSi2 and FeSi were formed at low substrate temperatures and high deposition rates, while films containing only β‐FeSi2 were formed at higher substrate temperatures and lower deposition rates. FeSi grains had the following epitaxial relationship to the Si substrate, FeSi(111)//Si(111) with FeSi(110)//Si(112). The microstructure of the silicide films varied with film thickness, as did the roughness at the silicide/Si interface. These results suggest that an Fe‐rich environment was created during the growth of the silicide films.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70762/2/JAPIAU-76-4-2202-1.pd
