Potassium Fertilizers

Buy Potassium Fertilizers

Potassium is one of the three base nutrients used in all fertilizers. It’s an essential nutrient for plant health and growth, as plants use potassium to absorb nitrogen from the ground and produce proteins. High potassium fertilizers enhance crop yields.

Manure and Composted Manure | Buy Potassium Fertilizers online

When potassium levels are low in the soil, the usual culprit is a low level of organic matter in the soil. Organic matter is rich in all three nutrients needed by plants, i.e., nitrogen, phosphorus, and potassium. Manure and composted manure are excellent sources of potassium for plants.

Wood Ash

Wood ash refers to the powdery remains of wood after it has been burnt for kindling. It’s a traditional source of potassium for plants used in plant rearing and agriculture for a long time.

Kelp Meal | Buy Potassium Fertilizers cheap

Kelp or seaweed has been used as a fertilizer for thousands of years. It supplies the necessary macronutrients of nitrogen, phosphorus, and potassium to the plants while enriching soil quality. You can apply kelp meal to plants in several different ways. You can mix it with the potting soil, but most farmers and gardeners prefer water-soluble versions.

Greensand | Buy Potassium Fertilizers for sale

Greensand is sediment from the sea also found as rocks. Greensand has been used as fertilizer for crops and plants since long before the Civil War. It’s a slow-release fertilizer also known as glauconite. The advantage of greensand is that too much greensand won’t harm the plant, unlike most other fertilizers. Your plants will simply absorb as much potassium as they need, and the rest of the greensand will remain in the soil, keeping it aerated.

Granite Dust | Buy Potassium Fertilizers from wholesalers

Granite dust or granite slurry is a valuable byproduct of granite manufacturing highly valued in the agricultural and commercial gardening industries as a fertilizer. Granite dust is rich in macro and micronutrients, including potassium, calcium, and aluminum, necessary for crop and plant growth.

Comfrey | Cheap Potassium Fertilizers wholesale

Comfrey is a perennial shrub that grows in North America, Europe, and South Asia. It’s known as a dynamic accumulator for its capacity to accumulate nutrients and improve the quality of the soil. The best way to use comfrey as a fertilizer is by incorporating freshly cut leaves of the plant in mulch. The mulch can be made up entirely of comfrey leaves as well.

Banana Peels and Eggshells | Buy Potassium Fertilizers in bulk

The banana fruit is known for being high in potassium, but the peels are also rich in potassium. There’s about 78.10 mg of potassium per gram of banana peel, approximately 0.0027 ounces per 0.002 pounds of banana peel. Eggshells are also a good source of potassium for plants, though the primary nutrient that plants derive from eggshells is calcium.

Wool Potting Compost | Buy Potassium Fertilizers from wholesalers

The use of sheep’s wool in compost has several benefits for the soil. It aerates the soil, prevents runoff of nutrients, and is a great slow-release fertilizer with high levels of nitrogen and potassium. You can use Wool as mulch to stop nutrient runoff. It has been used for this purpose since the 1900s. The absorbent nature of wool makes it hold onto water and fertilizers, preventing them from running off.

Coffee Grounds and Tea Leaves

Coffee ground and tea leaves are great for adding much-needed nutrients to the soil. Both coffee grounds and tea leaves are rich in nitrogen, phosphorus, and potassium, and dried grounds are richer in these nutrients than fresh grounds.

Organic Solution Grade Potassium Sulfate

Potassium sulfate is one of the main potassium-based fertilizers used in agriculture and gardening. It’s more expensive than the commonly used potassium muriate but is effective for improving the quality of yield in garden plants like tomatoes.

Muriate of Potash Granules

Muriate of potash or potassium chloride is the most easily available and commonly used potassium-based fertilizers. It’s typically available in granule form and mined from rock deposits.

Alfalfa Pellets

Alfalfa is a plant that needs a lot of potassium to grow. As a result, the plant itself contains high levels of potassium. Alfalfa pellets are typically used as animal feed, but their use in gardens as a green fertilizer has been growing over the years. The pellets can’t be used directly on the soil as they won’t break down quickly enough to be absorbed in the soil.

Cottonseed Meal

Cottonseed meal is the byproduct of processing cotton. Sometimes it’s used as feed for cattle, but one of the most effective uses of this byproduct is fertilizer. While cottonseed meal is typically known for its high nitrogen content, it does have a lot of potassium and is an effective source of potassium for plants.

Soybean Meal

Soybean meal is similar to alfalfa, with the added advantage of being easier to use. The meal is usually finely milled with a powdery texture. When used as a fertilizer, it can be directly sprinkled onto the soil to be effective.

Cucumber Skin Ash

Like wood ash, cucumber skins can be burned to produce ashes that are a rich source of potassium for your garden. While these are not easily available ingredients and not viable for large-scale use, they’re useful for home gardens.
