These are real pages from the book. The table of contents is the full one: 7 parts and 61 topics.
You're on a practice question: the soil test calls for 2 tons of lime per acre at 100% ECCE, and your ag lime is 60%. You've spread lime for twenty years, and the number still won't click.
The study guide gives you the formula in one line, between two others. Nothing on the page shows you why you divide and not multiply.
In this book, that same question is one page: the recommendation on top, the ECCE as a fraction, one arrow down. 2 ÷ 0.60 = 3.3 tons per acre, the same steps every time.
Other topics work the same way: CEC, the 4Rs, the IPM ladder, corn V stages by leaf collar, the units card for field math. Each one gets its own page.
Next time a lime question comes up, you run the same steps and answer it, no manual needed.
How the exams work, soil and water, nutrient management, IPM, crop management, field math and exam-week review: 65 pages, all illustrated
Think of it this way:
A grower calls from the field: his corn looks pale and he wants to know if it's nitrogen or sulfur. Or the exam asks the same thing in textbook words. You need to know where on the plant to look.
In the book you open the page on mobile and immobile nutrients and see the plant drawn: mobile nutrients show up on the lower leaves, immobile ones on the new growth.
Same with soil texture, the 4Rs, the IPM ladder, corn V stages and sprayer calibration: each one on its own page.
Crop Adviser Illustrated is 7 parts and 61 topics, all drawn, with stages, site-of-action groups and formulas at a glance at the end.
What you see drawn, you don't have to memorize.
The International and local board exams, the 4 competency areas on one map, how to read a performance objective and how to fit study between harvest and planting.
Soil texture in the triangle, structure and compaction, the soil profile, CEC, pH, soil water, infiltration and drainage, erosion and the USLE, conservation practices and cover crops.
The 4Rs, the 17 essential nutrients, mobile vs. immobile, deficiency symptoms on the leaf, the N cycle, P and K, fertilizer grades, soil sampling and test reports, MRTN, manure and N timing.
IPM in 5 steps, EIL vs. economic threshold, scouting patterns, insect life cycles, weed ID, herbicide groups and resistance, the disease triangle, SCN, fungicide and insecticide groups and the label.
Corn V and R stages, soybean stages, Feekes and Zadoks, growing degree days, hybrid selection, planting, stand counts, replant decisions, yield estimates and bushel weights.
The units card, lime rate adjusted for ECCE, pounds of product per nutrient rate, UAN in gal/acre, N-P-K blends, sprayer calibration by the 1/128 acre method, GPM and GPA, and tank mixes.
Stages, site-of-action groups and formulas at a glance, frequent mistakes on calculation questions and an exam-day checklist.
At the end of the book: Stages, site-of-action groups and formulas at a glance, plus an exam-day checklist.
Exam-style questions for all 4 areas, each answer explained with the page to go back to, so you find your weak spots before exam day.
The most common agronomy mistakes, from lime rates to sprayer calibration, each one drawn wrong and then right, so you can review them at a glance.

Yes. It doesn't start from zero and it doesn't read like a textbook: it takes what you already do in the field and lays it out the way the exam asks it, one drawn page per topic.
It follows the performance objectives for the International exam and is cross-checked with land-grant university extension publications, NRCS Standard 590 and the WSSA, FRAC and IRAC site-of-action classifications. Rates and code values are flagged so you can check them against the current edition and your local board's materials.
No. It's an independent study book, not affiliated with the American Society of Agronomy or any certification board. It doesn't give you a certificate or CEUs: certification comes from passing the exams and meeting your board's requirements.
The objectives tell you what can be asked; they don't explain it. This book puts each topic on one drawn page, works every calculation step by step in the same order, and adds practice questions that point you back to the page. Your board's objectives, your state's extension guides and the product label still come first.
No. They're written for this book, in the style of the exam, and each answer points you to the page to review.
The book and the 2 bonus books arrive as PDFs by email, at the address you enter at checkout. It's a one-time payment, no subscription.
In part. Both exams cover the same 4 competency areas, so the topics overlap. But your local exam also asks about your region's crops, pests, soils and state rules, and this book doesn't cover those state by state. For that part, use your local board's performance objectives and your state's extension guides.
Yes. The PDF prints on standard letter paper, at home or at a print shop, so you can keep it in the truck.
You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
No more rereading pages that don't stick.
Soil texture, the 4Rs and corn stages: you see them drawn and you've got them.
You walk into the exam knowing where everything is.
