AgriStats Manual – MC Edition
OVERVIEW
Welcome to AgriStats - an entirely
web-based data management system
– available to IPNI Staff and its
authorized Members.
AgriStats manages a global dataset on fertilizer use by crop. Current features include an ability to
compare regional resources and crop profile data for major crops grown in regions where IPNI conducts
its Programs. Currently, the geographic scale of the data is at the Country level.
AgriStats provides access to data on current, attainable, and potential yields, related nutrient use data
as well as the associated gaps between estimates for current farm practice and that which is realistically
attainable. Most data can be selected for projection on a global map.
A unique analysis tool also provides a boundary analysis approach to constructing medium to long-term
Chart Projections of agronomic fertilizer market development.
A newest feature is the Motion Chart section that will allow users to visualize trends in the data over
time.
The manual below assumes users will be familiar with basic navigation functions available in a web
browser. Please contact gsulewski@ipni.net if any questions arise from this manual or the website.
HOME SECTION
The Home section provides all the navigation links and convenient quick links to help guide new users.
The Home section also provides access to the systems required for managing user accounts, defining
custom regions, and managing data submissions into AgriStats (IPNI Staff only).
User Account Management
AgriStats uses a tiered system of account access designed to provide the typical requirements for each
user group that has access to AgriStats. As a Register Guest, your account grants access to the functions
outlined in the following Table.

Editing Your Profile
Registration begins the process of building your profile with a
minimum requirement of a full name, email address, and
affiliation. Once registered, users may view this profile, add
other contact or password data, or edit any existing data as
required.
Custom Region Management
Users are provided with the option of creating custom regions
to allow for quick, personalized comparisons across a specific
group of geographic regions.
• Custom regions are only required to have a name, and be activated (shown below).
• Next select the desired group of sub-regions that will
be associated with each Custom Region.
This custom region will now be available from the User Defined
Region pick list (shown below) when using the Crop Profile
Section (see section in manual for more).

AgriStats Manual – MC Edition
CROP PROFILE SECTION
The crop profile section provides access to a set of formatted Tables, the contents of which are
dependent upon a user’s query selections.
• Queries are constructed by selecting a combination of: 1) a geographic region or regions, 2) a
single year of range of years, and 3) a crop or crops.
• Since the year and crop selectors are optional, users are able to generate all available data for a
the particular region(s) of interest if these two selections are left blank.
Please note: Users should try to avoid queries that might generate tables of excessive size since this
increases the risk excessive response times from the web-based query generator.
Also note that query response time will be highly dependant upon the connection speed available.
The individual Tables have been organized to provide a range of regional data including:
1. Regional resources - selected indicators of resource availability, demographics and the
dependence of regional populations on agriculture.
2. Crop production - crop yields, harvested areas and production data, as well as respective
average annual growth rates for each.
3. Crop productivity - actual, attainable, and potential yields averaged over the last 10 years, as
well as respective average annual growth rates.
4. Yield gaps - actual crop yield averages and respective estimates of : (1) the portion of yield
which is realistically exploitable (2), that portion which remains due to regional constraints
related to climate, soil productivity, crop genetics or and common agronomic practices, and (3)
the full yield gap (1+2).

5. Current nutrient use - crop-wise fertilizer consumption and nutrient removal, which considers
both the current harvested product and an estimate of crop residue removal from the field.
Nutrient removal to use ratios are also provided.
6. Attainable nutrient use - crop-wise fertilizer consumption and nutrient removal based on ,
which considers both the harvested product from attainable yields and an estimate of crop
residue removal from the field. Nutrient removal to use ratios are also provided.
7. Current fertilizer use - an outline of actual crop-wise fertilizer application rates, percent crop
area fertilized, and the resulting fertilizer consumption.
8. Attainable fertilizer use - an outline of crop-wise fertilizer application rates required for the
attainable yield estimates, percent crop area fertilized that is also realistically attainable for the
region, and the resulting fertilizer consumption.
9. Fertilizer gaps - an outline of the differences between the realistically attainable and actual
fertilizer use scenarios.
Features within Crop Profile Tables
Column Sorting
All Tables allow for column sorting by clicking on the column header. Multiple column sorting is also
possible by using shift +click.
Data Export
Table results can be exported directly to an Excel worksheet for the purposes
of using AgriStats data externally.

PROJECTIONS SECTION
The projections section provides the ability to construct Agronomic Market Development Scenarios for
fertilizer consumption. The set of scenarios are designed to provide realistic boundaries for current and
future fertilizer use by crop and region.
• Each set of scenarios is user generated through their selection of: 1) geographic region, crop
(optional), and average annual growth rate (AAGR) of choice.
• The default AAGR is based on the past 10 years of historical data, but can be changed to
construct the projections on IPNI Staff estimations, or a third option is to specify your own
AAGR.
• Leaving the crop selection blank will result in the generation of fertilizer use projections for all
crops available for the region(s).

AgriStats Manual – MC Edition
Explanation of the Agronomic Market Development Scenarios
The boundary analysis for each region and crop is comprised of four models which expand from
historical/current consumption trends to deliver a medium to long-term projection range.
1. Historical/Current: Actual Consumption - portrays estimates of consumption up to the most recent
year (red line in example chart) based on current fertilizer application rates, harvested area, and
percent fertilized area.
2. Current: Intensification Potential - portrays the currently attainable shift (blue line in example
chart) in crop fertilization, the "current market development potential", based on attainable
fertilizer application rates, actual harvested area, and attainable percent fertilized area.
3. Future: Area Expansion Model - portrays future estimates of consumption based on current
expectations for fertilization practices and realistic expectations for future harvested areas (green
line in example chart). Assumes
current knowledge and
application rates would not
change and incentives for
farmers to apply fertilizer
remain constant.
4. Future: Intensification x Area
Expansion Model - portrays
future estimates of consumption
based attainable improvements
in fertilizer use and expected
changes in harvested area (pink
line in example chart), or the
"future market development
potential".
Note: Constraints to realizing the agronomic market development potential include among
others unfavorable economics (e.g., commodity prices), resource availability (e.g., fertilizer), or
lack of knowledge and technologies. The actual market development is expected to take place
between the portrayed boundaries of intensification and area expansion.

MOTION CHARTS SECTION (NEW)
The motion charts section is a new area designed to allow users to make visual comparisons with the
available data set in order to identify trends of interest.
The section is arranged to construct either Crop-centric or Region-centric comparisons through a three
step data filtering process.
Crop-centric comparisons
A crop-centric comparison is constructed through the selection of: (1) a geographic region or regions, (2)
a range of years (data for all available years will be shown if you do not choose from the list), and (3) a
single crop. Submit the query to obtain the motion chart.
The default chart is a scatter plot that can project all data associated with the combination of crop and
geographic regions selected.
To change the data displayed on
each axis, choose a new selection
from the drop downs on the
bottom and left sides. You may
make similar choices for color and
size along the right side.
To highlight a particular crop or
region, you may check them in the
list on the right side. All the labels
can be positioned as desired.
To operate the motion chart, click
the Play button in the lower left to
watch the changes in the data as it
moves through the tie series available.

The second option is to project the
data as a bar chart by selecting the
middle tab located on the upper right
corner of the Motion chart. Individual
series can be identified by clicking
their respective boxes or by mousingover
the chart itself.
The third option is to project the data
as a line chart by selecting the third
tab.
To change the data selection, find the ‘expand/collapse parameters’
toggle text at the top right corner of the screen.
Region-centric comparisons
A region-centric comparison is constructed through the selection of: (1) a single geographic region of
choice, (2) a range of years (data for all available years will be shown if you do not choose from the list),
and (3) a single crop or range of crops (data for all available crops will be shown if you do not choose a
crop from the list). As with crop-centric comparisons, submit the query to obtain the motion chart.

• Arable Land (ArA), total ('000 ha) primarily including annual crop lands, temporary meadows
and pastures.
• Arable Land per Person, Arable land/Total Population (ha)
• Agricultural Area (AA), total ('000 ha) including arable land, permanent crop land (long-term
multi-harvest crops) and permanent pastures (five years or more).

• Forested Area (FA), total ('000 ha)
Crop Production : Crop yields, harvested areas and production data, as well as respective average
annual growth rates for each. Data is provided from 1961 to the most recent year available. Sources:
FAO and Government websites.
• Area (A), harvested area (ha)
• Production (P), total (t)
• Yield (Y), Production/Area (kg/ha)
Crop Productivity :Actual, realistically attainable, and potential crop yields, as well as respective annual
growth rate averages for each. Sources: IPNI expert knowledge, field study, crop models.
• Attainable Yield (Ya), yield (kg/ha) of a modern variety that can be achieved in farmers' fields
with good crop management and ample nutrient supply. Attainable yield is limited by the
region's yield potential (see definition below) and other yield limiting factors in the growing
environment that could currently not be easily overcome by management (e.g., water limitation
to yield or low productivity on sandy soils). Investments in infrastructure (e.g., irrigation
facilities) or soil improvement could substantially increase attainable yield. The maximum
economic yield is often closely related to the attainable yield.
• Potential Yield (Yp), yield (kg/ha) assumed to be only limited by variety (modern, high yielding)
and climate (solar radiation, temperature). Note that by definition, potential yield is not water
limited. Potential yield represents the upper yield boundary for the currently available genetic
material.
Yield Gaps : Quantifies the portion of yield which is realistically exploitable and that which is not
exploitable due to regional constraints related to climate, soil productivity, crop genetics or and
common agronomic practices. Sources: IPNI expert knowledge, field study, crop models.

AgriStats Manual – MC Edition
• Exploitable Gap (Ya - Y), defined as the difference between Attainable Yield and Actual Yield,
this portion of yield (kg/ha) is limited by advancements in knowledge and technologies,
including adoption rate, that are expected to be surpassed.
• Remaining Gap (Yp - Ya), defined as the difference between Potential Yield and Attainable Yield,
this portion of yield (kg/ha) is limited by unfavorable economics (high inputs required following
the law of diminishing return), high risks of crop failure (increasing pest and disease pressure,
crop lodging, etc.), environmental limitations to high yield including water availability and poor
soil productivity, or unforeseen advances in crop production technology.
• Full Gap (Yp - Y), defined as the difference between Potential Yield and Actual Yield, this portion
of yield (kg/ha) is the sum of the exploitable and remaining Yield Gaps.
