Here's how to provide your plants with phosphorus for healthy growth:
Phosphorus is crucial for plant development, and you can supply it through several methods. These include using organic materials and commercially produced fertilizers.
Sources of Phosphorus for Plants
Here are some good ways to give plants phosphorus, drawing from organic and commercial options:
-
Organic Sources:
- Animal Manure: Chicken and horse manure are excellent sources of phosphorus. They release nutrients slowly, improving soil structure and fertility over time.
- Bone Meal: Bone meal is a slow-release source of phosphorus made from ground animal bones.
- Fish Emulsion: Fish emulsion provides a readily available source of phosphorus and other nutrients.
- Rock Phosphate: Rock phosphate is a natural mineral that releases phosphorus slowly into the soil.
-
Commercial Fertilizers:
- High Phosphorus Fertilizers: Fertilizers with a higher middle number in their N-P-K ratio, such as 10-20-5, provide a quick boost of phosphorus for plants. The middle number represents the percentage of phosphorus.
How to Apply Phosphorus
- Manure: Spread well-rotted manure around the base of plants and lightly work it into the soil.
- Bone Meal: Incorporate bone meal into the soil before planting or side-dress existing plants.
- Fish Emulsion: Dilute fish emulsion in water according to label instructions and apply as a soil drench or foliar spray.
- Rock Phosphate: Mix rock phosphate into the soil before planting. It works best in slightly acidic soil.
- Commercial Fertilizers: Follow the package instructions carefully, as over-fertilization can damage plants. Apply to the soil surrounding the root zone.
Tips for Using Phosphorus
- Soil Testing: It is good to test your soil to determine if a phosphorus deficiency exists before applying fertilizers.
- Balanced Nutrition: Ensure your plants have other essential nutrients like nitrogen (N) and potassium (K) for optimal growth, by using fertilizers with N-P-K ratio that meets your plant's needs.
- Proper Application: Avoid over-applying fertilizers, as this can cause nutrient imbalances.
By following these guidelines, you can effectively provide your plants with the phosphorus they need to thrive, using both natural and manufactured fertilizers. Remember, chicken and horse manure, bone meal, fish emulsion and rock phosphate are good sources. Fertilizers with a higher second number, such as 10-20-5, act quickly to boost phosphorus for plants.
