  • Dig an 8-inch-deep furrow and set the surplus soil to the outside. Plant one seed potato per 12 inches in the furrow.
  • 6 inches of soil should be used to plant the seed potatoes. Hydrate them thoroughly, but do not water them repeatedly until they’ve sprouted to prevent decay.
  • And once potato sprouts have emerged, add more soil on top of them. Continue this hilling process a couple of extra times to keep the potatoes from turning green due to sun radiation.

What Is the Purpose of Bone Meal Fertilizer?

Steamed animal bones are crushed into finer dust or granules and applied to field crops as a fertilizer. Bones are highly nutritious and have minerals that assist the crops, making them bigger and more resilient. Bone meal fertilizer, on the other hand, isn’t appropriate for all cases.

There are several advantages to using bone meal fertilizer as a nutrient-dense soil amendment: –

#1 Calcium-dense

Calcium is well-known for its role in the development of strong bones, but it is also useful to crops. This important mineral is abundant in bone meal fertilizer. It supports vigorous development by keeping your crops’ cell walls firm and healthy.

#2 Phosphorus-rich

Another important mineral present in bone meal fertilizer is phosphorus. Photosynthesis, roots, bloom and seed formation, energy transport within the plants, as well as other critical activities all rely on this component.

Phosphorus is the “P” in NPK, which you’ll see on fertilizer all the time. It strengthens pest attacks protection, increases fruit and seed output, and stimulates blossoming.

#3 Nitrogen is present in bone meals

The majority of pre-made bone meal fertilizers include nitrogen. An additional element required for a well-rounded soil supplement is this. 15-30-15 fertilizer is included in great brands like Miracle-Gro. This signifies that 15 percent of the material is nitrogen, 30 percent is phosphorus, and 15 percent is potassium. Plants require those three minerals to survive.

#4 Additional Soil Nutrients are Balanced by Bone Meal

Although manure and compost are beneficial to soil additions, they are typically heavy in nitrogen and poor in other components. What your plants require from the land is a delicate balance of nutrients that do not interfere with one another. Bone meal aids in achieving that equilibrium, allowing your crop to thrive.

#5 Blooming Plants’ Health Is Improved

Gardeners typically employ bone meal for flowering shrubs like roses and bulbs because plants require phosphorus to blossom. Initially, in the growing period, an infusion at the bottom of the plant can result in larger, more abundant flowering, as well as assist onions make bulbs. Bone meal is also applied to the root of plants precisely since they are flowering to encourage them to produce fruit.

How to Make Bone Meal Fertilizer?

Begin by assembling a bone collection. Usually, bones are saved in the refrigerator until you have enough. The bones must then be cleaned and sterilized before being used. One usually prepares broth to wash and disinfect the bones because They want to get the maximum out of these. Lay the bones out on a baking dish and bake for 10-fifteen min under the broiler.

Then, for 5-8 hours, slowly simmer these bones in just sufficient water to immerse them. By the completion of this period, the bones should have been readily stripped free of any remaining fatty or meat tissues. Make sure the bones get completely dry. Simply lay the bones onto a dish and leave these in a well-ventilated location to dry after they’ve been scrubbed clean.

Wait approximately a month for bones to dry off. This enables it to be simple to powder. Grind the bones together into powder form after they are stiff and dried. With a little effort and a mortar and crusher, you can do this. To make uniformly fine particles, proceed in tiny quantities at a moment.

What Should One Do If The Soil pH Is Over 7? If the pH of your ground exceeds 7, phosphorus will get locked in the surface and unreachable to your crops. If the soil tests alkaline (pH more than 7), start by lowering the pH with Cottonseed Meal, Peat Moss, Soil Sulfur, or Alkaline fertilizers.

What if the soil has a high calcium and phosphorus content? If one’s soil test shows that they also have enough calcium or phosphorus however not the others, a more focused treatment like high-phosphorus guano or Oyster Shell Flour for calcium would be a better option.

Tips to Use Bone Meal for Growing Potatoes

Producing potatoes naturally isn’t as difficult as some people believe. It only takes a little study into ground conditions, an awareness of what minerals your potatoes want and when they require them, and lastly, a comprehension of what natural chemicals you may use to provide those nutrients.

If you can’t obtain a bone meal, combine a high phosphorus granular fertilizer (high middle number) carefully into the base of the trench, then top this with an inch of new soil before actually planting the seed potatoes.

Root crops benefit from high-phosphorus fertilizers because they promote root and blossom formation. Bone meal is an excellent natural fertilizer for potato crops. When planting your potato, sprinkle just a little powdered bone meal on the soil surface that covers the potato seeds because when it rains, the fertilizer is disseminated into the soil and provides long-term nourishment to your produce.

Select tiny seed potatoes with a weight of 2 to 3 ounces (55-85g). Bigger potatoes should be split into bits before sowing, with at least three ‘eyes’ sprouting on each portion. Let the sliced portions of the chunks dry for approximately a day to produce a callous. Viruses as well as other diseases are less likely to infect the seed potato’s body as a result.

Drill ten to twelve-inch (25-30 cm) shallow pits or separate holes. To provide emerging potatoes the most freedom to spread, the soil around the sowing location should be properly cultivated and loose. Through each sprouting area, add a tiny spoonful of bone meal.

Phosphorus is abundant in bone meal, which itself is required for proper roots and potato growth. Each 12 to 14 inches, but one seed potato or piece (30-35 cm.) Potatoes would be shorter if they are planted closely together. Water thoroughly after covering the freshly planted tubers with a loose soil layer.
