STATISTICS OF FERTILIZERS AND PESTICIDES This chapter contains statistics on percentages of crop acres treated by various types of fertilizers and pesticides. Nitrogen, phosphate, and potash are the most common fertilizers; herbicides, insecti-cides, fungicides, and other chemicals are the main categories of pesticides. Other chemicals include. Why It’s Time to Stop Punishing Our Soils with Fertilizers Researcher Rick Haney travels the U.S. preaching the benefits of healthy soils. In a Yale Environment interview, he talks about the folly of pursuing ever-greater crop yields using fertilizers and other chemicals and how farmland can by restored through natural methods.
Impact of Fertilizers and Pesticides on Soil. tones/ Ha in and the demand for total fertilizer nutrients has been esti- ture of agricultural soils due to prolonged pesticide inputs. Ongoing work by the authors involves econometrically estimating this model of variable input demands for thirteen variable inputs (labor, pesticides, fertilizer, fuel and natural gas, electricity, purchased feed, purchased seed, purchased livestock, machinery repairs, building repairs, custom machinery hired, veterinary services, and other.
Fertilizer is a world market commodity subject to global supply and demand, and market fluctuations. The year of saw unprecedented demand for fertilizer and record prices (Figure 3). World price for fertilizer remained relatively constant from through , but in prices started to escalate. Among the typical fertilizer inputs of nitrogen, potassium and phosphorous, urea production for nitrogen dominates fertilizer energy use (Dept of Fertilizers, ). Since the urea production process is fairly standard, we assumed a fixed energy intensity of urea production and allocate aggregate fertilizer energy to crops state-wise, in Cited by: 7.

Estimation of Aggregate U.S. Demands for Fertilizer, Pesticides, and Other Inputs: A Model for Policy Analysis The method often proposed to meet environmental goals such as water quality improvement is input restriction, such as reduced fertilizer or pesticide use.

Department of Agriculture. Economic Research Service.]. Using cross-country panel data, this forms a macro-level physical production function for yield increases.
We confirm that fertilizer, modern variety seeds, and pesticides are key inputs to yield growth, even with aggregate data, and controlling for other factors such as human capital and land-labor by: Aggregate data on fertilizer consumption and use must be assembled from multiple sources with varying release dates.

Resource Structure of Agriculture: An Economic Analysis focuses on the quantitative economic analysis of the agricultural industry. The book first discusses the theory of resource demand. Topics include decision milieu in agriculture; aggregate demand for an input; and notes on the statistical estimation of the demand function for an Edition: 1.

ERS research also examines factors influencing volatile fertilizer markets and farmers' strategies to manage nutrient use under price uncertainty. ERS evaluates factors driving trends in the use and composition of pesticides in the United States.

This study uses a computable general equilibrium (CGE) model of the U.S. economy to estimate the economic effects of agricultural fertilizer and pesticide input reductions on individual farm sectors, and on the economy as a whole.
The costs of reducing agricultural chemicals using a market-based approach and a command-and-control approach are compared.

Their use of sales as a dependent variable generated an implicit estimate of aggregate US crop losses in of % at average pesticide use, far less than estimates of other studies (Pimentel et al.

That specification suggests that their estimate of pesticide productivity should be biased by: Tables in this product provide annual fertilizer use and price data at the national and State levels.

Unlike N, which includes fertilizer, manure, atmospheric deposition, and N fixation as inputs, P inputs comprise only two terms: fertilizer and manure P.

Reproductive failure, poisoning, and/or death (pollinators, pets, livestock, predators, children). Summary of Findings Summary of Findings The rapid growth in fertilizer consumption throughout the s and s—as more acreage was devoted to high-yield crop varieties and hybrids that responded well to more intensive use of commercial fertilizer—peaked at million nutrient short tons (1 short ton is equal to 2, pounds) in Soil degradation that leads to the loss of a soil's capacity to buffer nutrients, pesticides, and other inputs accelerates the degradation of surface water or groundwater quality.
Erosion not only results in the direct transport of sediment, nutrients, and pesticides to surface waters but also reduces the nutrient storage capacity of soils. As grazing systems are intensified there is a parallel increase in management, water use, fertilizer, pesticides, and other inputs.
The need is to find viable systems that can be integrated for crop, forage, and livestock production such that their complimentary benefits would allow for a more sustainable use of water and soil while maintaining. This paper reports meta-regressions of substitution elasticities between greenhouse gas (GHG) polluting and nonpolluting inputs in agricultural production, which is the main feedstock source for biofuel in the U.S.
We treat energy, fertilizer, and manure collectively as the “polluting input” and labor, land, and capital as nonpolluting by: 5. This page presents the methods underlying the ERS agricultural productivity accounts. This data set provides estimates of productivity growth in the U.S.
