About Tuzhi
Website Producer: Li Zeyu. A Geoscience Lover. The President of Geoscience Club of Shanghai Pinghe School.
Know the soil, farm it well.
The line is “Read the land. Farm it well.” This site is for people who work the field.
What Tuzhi does: photograph the field to match a problem; read the field guide by what you see; put lab-sheet words into plain speech; post a photo of your own field in Q&A.
What Tuzhi does not do: it does not replace an extension station or a lab; it does not hand you a pesticide brand as a prescription. If the crop is already in trouble, go to the local station now. Do not wait here.
Guides are written from what the field looks like. Each one has easy mix-ups and a rate range. Confirm rates with the local station and the label.
Made by Li Zeyu. That is not a sales pitch.
Copy is compiled by the producer. Confirm rates with a local agronomist. Public references include China’s soil-testing and formula fertilisation guide, common soil-science thresholds, and local extension leaflets. Not a prescription.
