In order to improve the prediction accuracy of agricultural machinery total power then to provide the basis for the agricultural mechanization development goals, the paper used gray GM(2,1) model in the prediction. Through the introduction of parameter λ to correct the background value and parameter ρ for multiple transformation on the initial data, the model was expanded to (2,1, , ) GM λ ρ mo...

The goal of this study was to quantify the economic role of dairy farming in New Mexico and to identify its linkages with allied industries in terms of income, value added, and employment impacts. An input-output model was used to estimate the direct, indirect, and induced impacts of the dairy farm industry on the economy of New Mexico. The results showed that in 2005, New Mexico's dairy farm i...

Improving agricultural total factor productivity is essential to achieving the high-quality and sustainable development of agriculture. As major global producers, G20 countries play an important role in product trade development. such, it well-positioned a positive improving productivity. This paper uses DEA-Malmquist index method measure (TFP) from 2010 2019, analyzes impact on TFP using two-w...

Abstract Measuring soil health indicators (SHIs), particularly total nitrogen (TN), is an important and challenging task that affects farmers’ decisions on timing, placement, quantity of fertilizers applied in the farms. Most existing methods to measure SHIs are in-lab wet chemistry or spectroscopy-based methods, which require significant human input effort, time-consuming, costly, low-throughp...

OBJECTIVE Estimate the annual US incidence and cost of fatal and nonfatal youth injury in agricultural settings. METHODS We used 2001-2006 Childhood Agricultural Injury Survey data to estimate the incidence of nonfatal injury and 2001-2006 Multiple Cause of Death data to estimate the incidence of fatal injury. To estimate the costs for injuries suffered by youth working/living in agricultural...

The response of agriculture to changes in relative prices is an important factor in the success of structural adjustment programs in Africa. In this paper I estimate supply functions for total agricultural output, food crops and export crops in 14 African countries for the years 1975 to 1990. Food and export crops are substitutes in production in the short run. Total agricultural output respond...
