Types Of Soil Tests
Soil testing helps understand the condition of soil. It guides farmers and gardeners to improve plant growth.
Different soil tests measure various factors like acidity, nutrients, and harmful substances.
Ph Testing
pH testing shows if soil is acidic, neutral, or alkaline. This affects how well plants absorb nutrients. The pH scale ranges from 0 to 14. A pH of 7 is neutral. Below 7 is acidic, and above 7 is alkaline.
Knowing the pH helps decide which plants will grow best. It also guides lime or sulfur use to adjust soil pH.
Nutrient Analysis
Nutrient analysis measures key elements in the soil. These include nitrogen, phosphorus, and potassium. These nutrients are vital for plant health.
- Nitrogen helps leaves grow green and strong.
- Phosphorus supports root and flower development.
- Potassium improves overall plant strength and disease resistance.
Other nutrients tested can be calcium, magnesium, and sulfur. Testing shows if fertilizer is needed and which type to use.
Contaminant Screening
Contaminant screening checks soil for harmful chemicals and metals. These can come from pollution, waste, or past land use.
| Contaminant | Source | Impact on Soil |
| Lead | Old paint, industrial waste | Poisonous to plants and animals |
| Arsenic | Pesticides, mining | Can stunt plant growth |
| Cadmium | Fertilizers, industrial pollution | Toxic to plants and humans |
