What Are the Benefits of Using Hemp Soil Amendments

What Are the Benefits of Using Hemp Soil Amendments?

Hemp soil amendments improve soil health and fertility greatly.

They are made from the hemp plant and have many benefits.

These include better soil structure, more nutrients to feed the healthy microbes, and the ability to hold onto moisture, making it so that you don’t have to water as often.

How do hemp soil amendments improve soil structure?

Hemp amendments help make soil better by making it less compact and by adding air to it – otherwise known as aeration.

The fibrous hemp hurd lets air pockets form in the soil.

This helps roots breathe and stops the soil from getting too wet.

Also, the organic matter in hemp makes the soil crumbly.

This makes it easier for water to go in and drain out.

What are the key nutrients found in hemp soil amendments?

Hemp soil additives have lots of nutrients that plants need to grow well and be healthy.

This includes nitrogenphosphorus, and potassium.

They also include nutrients like magnesiumironzinc, silica calcium and sulfur.

These help plants in many ways and keep them from lacking important nutrients.

Can hemp soil amendments be used for organic farming?

Yes, hemp soil amendments are great for organic farming.

They come from a totally natural and organic source: hemp, so they’re good for the environment.

Also, they’re safe to use for growing and producing organic products.

This means they can make the soil better without adding bad chemicals or synthetic fertilizers or pesticides and herbicides.

What are the 4 Hemp Products Used for Soil Amendment

What are the 4 Hemp Products Used for Soil Amendment

Organic amendments from hemp are natural and sustainable and help increase the micronutrient levels of your vegetables and other plants, whether you’re growing them in a pot, mixing with potting soil, or just using them right in your garden bed.

They enhance your soil and play a vital role in enhancing the nutrients in your plants, and they can be used for both indoor and outdoor plants as well.

They not only add nutrients but can help help soil hold moisture and improve deficiencies or imbalances.

This boosts the plant’s nutrient intake and health, leading to better harvests.

So what are these four raw hemp fiber and seed products that can be applied as a soil amendment?

#1 Hemp Seed Hulls for Soil Amendment

Hemp seed hulls are light and fibrous, from processing hemp seeds.

They boost soil’s structure, letting air and water move better and combats evaporation in dry conditions.

These hulls help hold moisture and slowly feed plants essential nutrients.

The outer shell of the hemp seed serves as a biodegradable nutrient provider and helps with soil aeration simultaneously.

Its tiny size is akin to perlite, but it decomposes more rapidly.

Additionally, it makes an excellent alternative to soy hulls for those cultivating mushrooms.

Once decomposed, it possesses an NPK rating of 2-.5-.3.

#2 Hemp Hurd Fiber as a Soil Amendment

The woody core, or hemp hurd fiber, helps condition soil well.

It improves aeration, avoids soil compaction, and supports roots.

This fiber also keeps soil moist, lessening the need for water.

Hemp hurd provides an additional benefit for soil aeration.

Hemp hurd is available in large and small pieces.

We have found that both sizes work well so it’s up to you what you’d like to use.

Additionally, it serves as an effective mulch for controlling weed growth.

A single application of hemp hurd can prevent weeds for up to a year.

It decomposes more quickly than wood, contributing organic material to your soil and microbes.

Once decomposed, it has an NPK ratio of .4-0-1.

#3 Hemp Bast Fiber as an addition to Soil Amendment

The outer hemp stalk layer, bast fiber, is full of nutrients.

It’s great for enriching soils over time.

Fiber improves soil quality, aiding drainage and welcoming helpful microorganisms.

Hemp fiber serves as an excellent soil amendment and provides optimal water retention.

It can be torn into small pieces and incorporated into the soil or placed on the soil surface to prevent it from drying out.

Additionally, hemp fiber is useful for creating seed mats and for managing erosion.

Many of our customers will use a combination of both the bast and hemp hurd fibers.

Upon decomposition, hemp fiber contributes an NPK value of 0.4-0-1.

#4 Hemp Seed Cake as a Soil Amendment Additive

Hemp seed cake, as a byproduct from extracting hemp seed oil, is rich in nitrogen.

This nutrient is key for plant growth.

It slowly feeds plants with nitrogen, benefiting them for a long time.

Hemp seed cake proteins can be incorporated into your soil as an organic, plant-derived fertilizer.

When decomposed, hemp seed cake (H3o) offers an NPK ratio of 4-3-1, whereas H20 provides a ratio of 4-2-1.

These alternatives are excellent for enriching your soil, ensuring a steady supply of compounds rich in bio-nutrients to your plants throughout the growing season, thus eliminating the need for weekly feedings.
