Discover the difference between organic foods and their traditionally grown counterparts when it comes to nutrition, safety and price. By Mayo Clinic Staff. Once found only in health food stores, organic food is now a regular feature at most supermarkets. And that's created a bit of a dilemma in the produce aisle. On one hand, you have a conventionally grown apple. On the other, you have one that's organic. Both apples are firm, shiny and red. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.
Vegetable Gardening: Selecting a Fertilizer. All plants need nutrients for growth. Gardeners can provide supplemental nutrients to plants by applying fertilizers in the form of composted organic material, synthetic fertilizer, or a specific mineral such as iron.hen selecting a fertilizer, look at the three numbers on the bag. They will read something like 15-0-15 or 16-2-8. The first number represents the percentage of nitrogen in the bag, the second refers to phosphorus, and the third number is the amount of potassium.
Types of Fertilizer. There are many options for how you convey nutrients to your plants. Many gardeners use a combination of different fertilizers and techniques. Try using granular products or manures to supply the main nutrients and liquids to correct minor deficiencies or quickly boost growth.ardeners who wish to avoid chemical fertilizers can also use fish emulsions or manure teas. Fish emulsion, which is usually high in nitrogen but low in phosphorus, is mixed with water and sprinkled around plants every two to three weeks, or as needed. It typically has a 5-1-1 analysis.
