Plants indicate soil.
Plants indicate soil conditions. Look at the grass in the plot, know the real soil. Plan the soil improvement properly.

Observing grasses and weeds in an area is a folk method that helps to assess soil conditions easily and free of charge, because each plant reflects soil conditions such as tightness, humidity, and acidity-alkalinity. However, it is only a preliminary sign, it can be aberrated by seasons, chemicals, or area adjustments. It is best to observe several points in the plot before summarizing soil conditions.

# Main thought important before reading plants indicate soil
Before you apply it, farmers should understand these three digits.
1.Look at many kinds together. Not one kind → Because many kinds of mixed grass indicate that the soil has many conditions in the plot.
2. Look at the area to be wide. Not a small point →. Because the data from a single point may not represent the whole plot.
3.Always watch the accompanying season → Because the rainy season and the dry season make the upward plant species very different.

# Prag grass→ Tight soil / dry soil
It is often found in packed soil, difficult seepage water and low humidity.
Common Cause
1. Plow often until the soil is tight downstairs.
2. Lack of organic matter
Solution
1. Add manure / compost
2. Plow a clay bomb (if there is a solid layer of soil)
---
# Raven's foot grass→ Degraded soil / tight soil
It's a sign of soil being heavily used, low in nutrients.
Solution
1. Grow soil plants (green beans, orphan beans)
2. Stop burning stubble. Add organic matter.
---
# Grass→ Acid soil
Good resistance to acidic soil conditions, so it is often higher in low pH areas.
Solution
1.Insert pH adjustable dolomite mortar
2. Increase organic fertilizer, reduce long-term acidity.
---
# Pork grass→ Loam / Moist
Indicates that the soil has good moisture, but be careful of drainage.
A utilitarian approach
1. Ideal soil conditions, plant vegetables, kitchen garden
2. Water should be controlled, not trapped
---
♪ Maiyrab → Firm soil / compressed
Found in hard or often trampled land areas.
Solution
1. Deep shoveling
2. Add manure and cover crop debris.
---
# Broad-leaved weeds → relatively complete soil
1. Such as stone pawn vegetables, wild spinach. Many species often rise in soil with enough nutrients.
2. Caution: Even good soil, but still need to control not to snatch the main crop food.
---
♪ Hydrophilic plants (sai grass, lung vegetables) → dry soil / waterlogging
Reflects that the drainage system is poor.
Solution
1. Make a drainage groove
2. Lift the groove, transform, plant
3. Structure the soil.
---
# Bird Rice segmental grass → Moist soil / Quite complete
It is found in areas with good humidity and moderate to good nutrients.
A utilitarian approach
1.Use as a sign that the soil is starting to recover
2. Suitable for growing many crops
---
# More information that farmers often overlook
1.Same soil but different
For example, the rim of the plot may be dry, but the middle of the plot may be damp or frizzy.
2. Weeds change according to management.
- Fertilize → Weed change kind
- Plow often → Firm soil. Weed resistant up instead.
3. The use of chemicals to affect plants indicates
- Some species disappear, not better soil, but because they are eliminated.

# How to apply in real plots (simple)
1. Walk, explore, convert 3-5 points.
2. Write down the most common kind of grass.
3. Compared with soil conditions
4. Plan one section at a time (do not need to do both conversions at the same time)

The spontaneous crops in the plot are not just weeds, but "soil indicators" that can be used by farmers. If you read them, it will reduce the cost of soil analysis and help you plan soil improvement on a more direct basis. As the soil improves, the main crops will be stronger, productivity will increase, and unnecessary use of chemical fertilizers. Let's study this approach to your agricultural plots.
