Soil Nutrients and Management
- Nitrogen (N) 1
- Phosphorus (P) 2
- Potassium (K) 2
Soil pH
- Effect of acidity-alkalinity to nutrient availability in the soils
- Amendment for soil acidity
Soil testing for NPK
- Steps employed in rapid test of N-P-K
- Things to remember when use soil test kit
Steps in use of soil test kit
– Soil sample preparation and N-P-K extraction from soils
– Ammonium measurement procedure
– Nitrate measurement procedure
– Phosphorus measurement procedure
– Potassium measurement procedure
– Testing soil pH
Benefit:
1. Used to analyze the amount of plant nutrients in the soil
2. Tell the state of soil fertility in real conditions.
3. Used to analyze soil to combine with other data. To give advice on common fertilizer for plants
4. Can be portable in the farm condition, easy to use, convenient and fast, with cheap price
Attribute:
The NPK and pH monitoring kit can analyze useful nitrogen of the soil in the form of ammonium nitrate, helpful phosphorus. Useful potassium And soil reaction values (pH) of 50 samples
