Plants need nourishment to grow. Throughout nature, plants use bacteria…
…and fungi to scavenge nutrients from various sources…
…including soil nutrients and gases released during decomposition.
However, these systems are not as robust under cultivation.
All houseplants, from lawn grass to houseplants, need a little help to thrive. Fertilizer can help.
Organic fertilizer support and stimulate plants’ natural processes of self-feeding.
Microorganisms in the soil consume the fertilizer, releasing its nutrients to the plants.
The result is improved soil aeration and water holding capacity…
…as well as a healthier physical environment for plants.
Organic fertilizer with an optimal NPK ratio (particulate nitrogen, phosphorus, and potassium)…
…will aid the plants in thriving. They’re made of natural ingredients like plant scraps, animal waste, and minerals.
Some are liquid, while others are dry.
A high-quality fertilizer requires minimal processing, is easy to apply, and has a consistent texture.
By providing a balance of nutrients, quality ingredients…
…and an application method that suits the gardener…
…organic fertilizer makes edible or ornamental plants healthier.
Before we move into next section, let’s hear Julia’s story…
My cannabis plants needed some help. I was using fish emulsion w good results but I needed a boost.
This organic fertilizer I bought days ago made a fast improvement,
I mixed a handful with water and poured around the plants
and in a few days plants were getting greener and I cud see faster growth.
Very inexpensive. I just ordered 3 more 4 pound bags!
Let’s get started…
Organic Fertilizer Types
You need to choose the right type or combination of organic fertilizers for your garden.
Some fertilizers come from plants only, while others are from animals.
Some products contain a mix of plant, mineral, and animal-based ingredients.
It’s not just a matter of personal preference; these products actually serve different purposes.
Compost, cottonseed meal, alfalfa meal, soybean meal…
…and seaweed are all examples of plant-based organic fertilizers.
Cottonseed meal and soybean meal both contain up to 7 percent nitrogen…
…but most plant-based fertilizers have lower levels of nutrients.
Fertilizers of this type are best known as sources of soil-improving carbon, enzymes…
…and natural plant growth stimulants that are not found anywhere else.
They break down quickly and make excellent soil conditioners.
Compared to their plant-based counterparts, animal-based fertilizers…
…(such as blood meal, bone meal, and fish meal) contain significantly more macronutrients…
…(nitrogen, phosphorus, and potassium).
Using waste materials from meat and fish processing plants, these fertilizers are made.
The nutrients in blood meal and bone meal slowly release throughout the growing season.
Typically, fish emulsion is used as a fast-acting liquid fertilizer.
It is not true that all inorganic fertilizers are synthetic.
The use of mineral fertilizers is not technically “organic” since they do not contain carbon…
…but they can be used in an organic fertility system.
These are excellent sources of trace elements that may not be found in other fertilizers.
A natural source of phosphorus such as rock phosphate is mined from clay deposits.
Aside from nearly 4 percent phosphorus, it contains high levels of calcium…
…nitrogen, potassium, magnesium, iron, manganese, copper, and boron.
Greensand is a type of sand or sandstone found in shallow marine sediments.
In addition to potassium, it is rich in iron, magnesium, calcium, phosphoric acid, and a variety of trace minerals.
Most organic fertilizers contain a combination of these types to provide a balance of essential macro and micronutrients, plus beneficial microbes that help make the nutrients available.Mark Wolfe Writer Specializes in Garden
