Suggest future needs in considering research on economics of fertihzer use. Concepts and Principles Involved in the Economics of Fertilizer Use A. Early Concepts concerning Crop-Yield Response TO Fertilizers Early research concerning plant nutrients was devoted largely to determining elements essential to the growth, development, and Cited by: Operating costs have increased and fertilizer inputs have increased more compared to most other crop inputs, such as herbicides and fuel.

The fertilizer costs as a percentage of operating costs are 29 percent, 33 percent, 37 percent and 48 percent, respectively for the years, and   That is what happened during We had a supply constraint, as the market had not imported as much fertilizer as it should have.

But there were good crop economics, so the customers paid more to get what they needed. So going forward the next two or three years, the biggest factor in the fertilizer market will be the new supply coming on-stream. expectation are significant factors that affect fertilizer use among maize farmers.

Olwande et al., () in Kenya also confirm that age, education, credit, presence of a cash crop, distance to fertilizer market and agro ecological potential significantly influenced the use of fertilizer by smallholder farmers.

Akpan andCited by: The economics of fertilizers. The practical goal is to determine how much nutrient material to add. Since the farmer wants to know how much profit to expect if he buys extra fertilizer, the tests are interpreted as an estimation of increased crop production that will result from nutrient additions.

Cost of nutrients must be balanced against value of crop or even against alternative procedures. Authors: Reetz, H.F. Publisher: IFA, Paris, France, May Date of Publication: 20 May Language: English A reference guide to improve general understanding of the best management practices for fertilizer use throughout the world to enhance crop production, improve farm profitability and resource efficiency, and reduce environmental impacts related to fertilizer use in crop production.

This publication reviews these various issues, substantiated by examples from each country, and analyzes available statistics on fertilizer use by cropPublisher's description.

Fertilizer Use and Crop Yields in the United States The National Soil and Fertilizer Research Com- mittee, recognizing the crucial relationship of fertilizers to our national welfare, charged the Fertilizer Work Group with the responsibility of (1) assembling and analyzing experimental data relating to the fertilizer requirements of crops and.

Food production and economics of fertilizer use. March 3, By Tom Jensen* However, when they saw what the margins were using current fertilizer and crop prices, fertilizer rates have in most cases remained similar to recent years and margins have increased.

An example in Table 1 shows estimated returns over the years, a Total NPK = total use / requirements in million tons N + P 2 O 5 + K 2 O. b NPK use/ha is the use/requirement in kg N + P 2 O 5 + K 2 O per hectare of harvested land. c FM, FH, LF = fertilizer scenarios; FM = medium variant, FH = high variant and FL = low variant of the medium production scenario.

The functions were used to reproduce the fertilizer use for the developing regions for To overcome this pitfall, optimization of fertilizer use is aimed at maximizing farmer profit from fertilizer use.

Determining the economics of fertilizer use requires crop nutrient response functions. Results of numerous studies from different AEZ were used to capture crop responses. The general objective of the study is to examine determinants of fertilizer use among smallholder food crop farmers in Ondo state, Nigeria.

The specific objectives are to: Examine some socio-economic characteristics of food crop farmers in Ondo state, Nigeria. Examine fertilizer use among the food crop farmers in the study area Determine the File Size: KB. Crop responses to applied nutrients needs to be considered in addition to the farmer’s land allocation to different crops, the value of the produce, the costs of fertilizer use and the money available for fertilizer use.

What is optimization. Optimization is the process of identifying solutions that minimize or maximize a function’s. 1. Introduction. Achieving food security is a key agenda that is eluding governments in sub-Saharan Africa (SSA) (Shapouri et al., ).Low productivity of food crops due to low nutrient application, in a region that has faced land degradation for several decades, is one of the major contributors to food insecurity in SSA (IFDC,Shapouri et al.,Muller et al., ), besides Cited by: Because of the various resources needed to produce it and the enormous scope of distribution around the world, fertilizer is closely tied with many other industries.

Its cost then can be affected by several economic factors, including supply and demand, responses to commodity prices and global supply. These factors are.

This is the third publication on "Fertilizer Use by Crop" produced by the Food and Agriculture Organization of the United Nations (FAO), the International Fertilizer Development Centre (IFDC) and the International Fertilizer Industry Association (IF A). The first issue was published in and the second in The responseFile Size: 1MB.

Fertilizer demand is influenced by the evolution of planted area and yields, the crop mix, crop prices and fertilizer-to-crop price ratios, fertilizer subsidy regimes, nutrient management regulations, nutrient recycling practices and innovation. Nitrogen is by far the largest nutrient, accounting for almost 60% of total consumption.

Fertilizer reduces the carbon footprint of farming Application Higher efficiency with nitrates Precision farming tools Fertilizer - an efficient solar energy catalyst Production is a marginal part of the carbon footprint; efficient application is more important Huge positive effects of fertilizer use, since higher yields enable lower land area use.

Economics and Agronomy and Horticulture Departments at UNL. The tool considers the land area that the farmer wishes to plant to each crop, expected commodity values at harvest, the costs of fertilizer use and the budget constraint.

The output includes the re-commended fertilizer rate. The evidence presented shows the benefits of high fertilizer inputs to produce high maize yields, thereby reducing the cost of grain production per hectare.

A clear relationship between soil test values for K and relative maize yield (yield obtained/maximum obtainable under local conditions) was established on a silty clay soil in Natal, S.

by:   Rick Gilbertson, crop consultant with Pro Ag Crop Consultants Inc., says that farm operations spend more time analyzing economics of input decisions than in years past, and that fall fertilizer can be an attractive option as fall prices are generally lower than spring prices.

Also, dealer equipment and applicators are more available. Just the facts.Fertilizers. Boost yields and reduce input costs by more efficiently and effectively applying fertilizer. This section covers the equipment, technology, and application methods for better nitrogen management.
