Benefits of Alfalfa Meal

Alfalfa meal is packed with nutrients that offer numerous benefits for your plants and soil. Let’s take a closer look at some of the top benefits of using alfalfa meal in your garden.

N-P-K Value and micro-nutrients in alfalfa meal

Alfalfa meal is an excellent source of nitrogen, phosphorus, and potassium, with an average N-P-K value of 3-1-2. This makes it a perfect fertilizer to replenish lost nitrogen in your soil. Additionally, alfalfa meal contains essential micro-nutrients such as calcium, magnesium, sulfur, manganese, iron, copper, boron, and zinc, which support plant growth and development. These micro-nutrients not only promote plant growth but also contribute to building healthy soil.

Growth hormone Triacontanol and its effects on plant growth

Alfalfa contains a natural growth hormone called Triacontanol, which stimulates plant growth and development. This hormone aids in the development of lateral branches, leading to larger, healthier plants with more bud sites. It also enhances fruit size and flavor, resulting in amazing results. By using alfalfa meal in your garden, you can achieve healthier, more robust crops.

Improving soil health with alfalfa meal

Not only is alfalfa meal a fantastic nutrient source for your plants, but it also improves soil health. It contains trace minerals that help build soil health and promote a healthy soil ecosystem. As a natural soil conditioner, alfalfa meal improves soil structure and water-holding capacity. It also attracts earthworms and other beneficial microbes, leading to better soil aeration and water retention.

Pest resistance and the repelling effects of saponins in alfalfa meal

The high level of saponins in alfalfa meal helps repel pests, making it an effective and natural way to protect your plants. Saponins act as a natural detergent-like compound that inhibits the feeding of certain insects and pests. By incorporating alfalfa meal into your garden, you can reduce the use of harmful pesticides.

Eco-friendliness and sustainability of alfalfa as a renewable resource

Alfalfa is a renewable resource that is cultivated without the use of synthetic fertilizers or pesticides. By using alfalfa meal in your garden, you’re making an environmentally conscious choice that promotes sustainable agriculture. Furthermore, alfalfa meal is biodegradable and safe for the environment.

Using Alfalfa Meal in the Garden

Alfalfa meal is a versatile organic soil amendment that can be used in various ways to enhance plant growth and soil health.

One common method is applying alfalfa meal as a dry soil amendment. Simply broadcast the meal around your garden and let the worms and microbes do the rest. Alternatively, you can mix it into the soil by tilling or manually mixing it.

Another approach is making alfalfa tea for your plants. Soak the meal in water for a day or two and use the resulting liquid to water your plants. You can also add alfalfa tea to compost teas when brewing with air pumps, providing a food source for the microbes in the compost.

Fermented plant extracts using alfalfa meal are gaining popularity in natural farming practices. You can ferment fresh or rehydrated dried alfalfa meal with other plants like kelp meal, comfrey, nettles, and yarrow. The resulting concentrate serves as a plant growth tonic and can be applied via soil drench.

Alfalfa meal is also an excellent compost activator, supplying nitrogen and protein that speed up the composting process. It can also revive a stalled compost pile.

For veganic gardeners, alfalfa meal is a fantastic substitute for animal-based nitrogen sources. You can blend it with other soil amendments, such as gypsum, basalt, azomite, lime, rock phosphate, and kelp meal, to create a complete veganic all-purpose fertilizer.

Incorporating alfalfa meal into your gardening practices is a great way to increase organic matter, provide essential nutrients, and promote healthy soil and plant growth.

Dosage guidelines and frequency of application: To achieve the best results with alfalfa meal, it’s important to follow dosage guidelines and apply it at the correct frequency. As a general rule, you should apply 1/2 cup of alfalfa meal per plant (30L pot) or 1 cup per square meter to your soil. This will ensure that your plants receive the right amount of nutrients without causing any harm. Reapply alfalfa meal every 6-10 weeks to ensure a consistent supply of nutrients.

How to Properly Store Alfalfa Meal

Proper storage is key to maintaining the quality and effectiveness of alfalfa meal. Store it in a cool, dry place, away from direct sunlight. An airtight container is recommended to prevent moisture and air from affecting its quality. When stored correctly, alfalfa meal can last for several months without losing its potency.

Precautions to Take When Using Alfalfa Meal

While alfalfa meal is generally safe to use, there are a few precautions to consider to avoid potential problems. Source non-GMO alfalfa to ensure you’re using a high-quality product. Avoid over-application, as it can lead to nutrient imbalances in the soil. Additionally, be mindful of any allergies or sensitivities to alfalfa and wear gloves and a mask when handling large quantities to prevent inhaling dust particles.
