7 best organic extra fertilizers

Organic extra fertilizers are a type of plant nutrient designed to enhance the growth and health of plants in gardening and agriculture. These fertilizers are considered "organic" because they are derived from natural sources and are typically free from synthetic chemicals or additives. Here are some key points about organic extra fertilizers:

  1. Natural Ingredients: Organic extra fertilizers are made from natural materials, such as compost, animal manure, bone meal, seaweed, and other organic matter. These ingredients are rich in essential nutrients like nitrogen, phosphorus, and potassium (NPK), as well as micronutrients.

  2. Slow-Release: Many organic extra fertilizers are slow-release, which means they gradually release nutrients into the soil over an extended period. This slow-release characteristic helps prevent nutrient leaching and provides a more sustained source of nutrition for plants.

  3. Soil Health: These fertilizers not only nourish plants but also improve soil health. They enhance the soil's organic matter content, increase microbial activity, and improve its overall structure and fertility.

  4. No Harsh Chemicals: Organic extra fertilizers do not contain synthetic chemicals, pesticides, or herbicides. This makes them a more environmentally friendly choice and reduces the risk of chemical residues in the soil and on plants.

  5. Plant Compatibility: Organic fertilizers are suitable for a wide range of plants, including vegetables, fruits, herbs, flowers, and ornamental plants. They are often used in organic gardening and farming practices.

  6. Nutrient Balance: These fertilizers are formulated to provide a balanced nutrient profile, promoting healthy root development, flowering, and fruiting. The NPK ratios can vary depending on the specific product and plant requirements.

  7. Environmental Benefits: Using organic extra fertilizers can contribute to sustainable and eco-friendly gardening practices. They promote soil conservation, reduce the environmental impact of chemical runoff, and support biodiversity in the garden.

  8. Application Methods: Organic extra fertilizers can be applied in various ways, including broadcasting over the soil surface, mixing into the soil during planting, or as a top dressing for established plants. The application method may depend on the product's form (granular, liquid, or powder).

  9. Certification: Some organic extra fertilizers may carry certification labels, such as the USDA Organic seal, to verify their organic status. These certifications indicate that the product meets specific organic farming standards.

It's important for gardeners and farmers to choose the right organic extra fertilizer based on their specific plant needs and soil conditions.Soil testing can help determine nutrient deficiencies and guide fertilizer selection and application rates. Additionally, following recommended application guidelines and scheduling can help ensure that plants receive the appropriate nutrients for healthy growth and productivity.

User questions & answers

Question: What is the solution (NPK) on this
Answer: There is no such listing as "NPK" on the ingredient percentages
Question: For a potted meyer lemon tree, how much should I use
Answer: My lemon tree is only about 2 ft. tall and has been inside all winter. I added 1 3/4C. Jobe's fertilizer and watered it well. that was two days ago and it appears to be doing very well. Because my tree has been inside I have been misting the leaves every day.It had about 50 blossoms on it and is very healthy. I hope to plant it in the ground in April or May.,
Question: What is the percentage of nitrogen, phosphate and potassium in the fertilizer
Answer: This fertilizer is 4-4-4. The first number indicates 4% nitrogen, second 4% phosphorus and the third 4% potassium. The best way is to incorporate 4 pounds of 4-4-4 per 100 sq.ft. prior to planting. This kind of fertilizer is called "all purpose" fertilizer. My recommendation is that you analyze your soil with an inexpensive test kit (Amazon has them). Then decide what you want to grow and research on-line what the optimum fertilization ranges are for your specific plants or vegetables. Then, if you incorporate the all purpose fertilizer into you soil before planting you can spot supplement with specific fertilizers as needed. There are many organic solutions available to you. The great thing about Jobe's -09526 is that it is organic so you will be starting off the right way. Lots of luck with your plants.
Question: what are the actual ingredients
Answer: Protein Hydrolysate from feather meal, bone meal, composted poultry manure, sulfate of potash and various bacteria, endomycorrhizae, ectomycorrhzae and archaea.

User questions & answers

Question: Does this work on peonies to promote more blooms
Answer: Yes, this will promote more blooms. Because the middle number is highest, (3-9-4) this blend will encourage your peonies to bloom well. Make sure to supplement with Calcium (bone meal) because strong stems require calcium! Add according to directions. Mix into soil around the base and drip line of your peony bush, then water well. If you are planting peonies in the ground for the first time, ask your local nursery if you should protect the roots from gophers. If so, this will require more preparation, but will be well worth it. Best of luck to you.

Question: My back yard was just seeded with new grass. I was told to fertilize it once the grass just comes up, with a 20-15-10 mix. Will this fertilizer work
Answer: Hi, J. Catlin! Ratio of Scotts Lawn Food is 32-0-4 on a new bag that I have- the 15k sq ft bag has long been thrown in the trash. I elected to not use the bag I have left because it would have been TOO MUCH on my lawn!. This is NOT one of those items where ,if a little bit does a little good... you know the rest! You must follow the directions when using this product!!! As you can see from the first number (nitrogen), all manner of bad stuff will happen to the grass if over applied. Conversely, it will do a fantastic job if properly applied. At least that has been my experience when using the product. Good Luck! JBH

For best results, apply with a Scotts drop or rotary spreader. Grass will become greener within 1 to 3 weeks after application (may vary depending on weather conditions). Can even be used with new lawns, before or after seeding or sodding. See product label for complete instructions.

Tips for Lawn Care Success

First, regular feedings help your lawn look it’s best and provide the nutrients it needs to withstand the stresses of weeds, weather and activity.

Secondly, after you mow leave the grass clippings on the lawn! This allows grass to use water more effectively.

Finally, water; utilize nature’s sprinkler as much as possible. When you do have to water, do it between 6 and 10AM - less water is lost to evaporation and more reaches the roots.
