A Revolutionary Guide to Crop Nutrition Through Leaf & Petiole Testing
Learn to Read the Language of Your Crops—and Feed Only What They Ask For
Ask the Plant
is more than a book—it’s a turning point in modern agronomy. Based on the foundational work of agronomist K. Chandler and presented through the lens of Acres USA founder Charles Walters, this essential guide teaches farmers and growers how to let the plant speak first
—then fertilize accordingly.
Rather than force-feeding with high doses of synthetic nitrogen, this book outlines how to monitor nutrient levels through leaf and petiole testing, interpret the plant’s true needs, and apply targeted, efficient, and biologically compatible nutrition.
What You’ll Learn
How to use leaf and petiole tissue testing
as a real-time diagnostic tool
Why conventional NPK models fall short in long-term soil health
How to fine-tune fertilizer programs
using plant signals—not guesswork
The role of organic matter and mineral balance
in sustainable productivity
Strategies to reduce inputs while increasing crop health and quality
Why This Book Matters
After more than 70 years of conventional agriculture mining soils without fully replenishing them, growers are seeing the effects: nutrient lockout, declining organic matter, and weak crop performance.
Ask the Plant
offers a practical way forward—by teaching you to work with biology, not against it.
