Best Organic Fertilizer For Tomatoes

Best Organic Fertilizer For Tomatoes

Tomato is one of the widely consumed fruit vegetables; this vegetable is known for its copious benefits in human’s healthy and overall wellness of the body. The cultivation of tomato can be enhanced by fertilizers; natural fertilizers help to increase yield, improve soil properties, and enhance the quality of the tomato fruits after harvest.

The application of fertilizers to the tomato plant is a major post-planting operation of tomato cultivation. You may not achieve a reasonable or cost-effective yield if the tomato is planted without the application of natural fertilizer or other forms of fertilizer. Why?

This is because the soil you want to plant on may be deficient of beneficial nutrient elements and needed replenishment through fertilization. This is why soil testing is highly recommended before planting tomatoes.

The replenishment of the soil before planting tomato is best done using organic fertilizers. Natural fertilizers are organic products that have been extracted from living things or the earth. They can either be plant-derived or animal-derived. Some examples are mushroom manure, blood meal, bone meal, cottonseed meal, kelp meal, poultry or horse manure, and compost.

Examples of naturally occurring organic fertilizers include manure, slurry, worm castings, peat, seaweed, and guano. Green manure crops are also grown to add nutrients to the soil. Naturally occurring minerals such as rock phosphate, sulfate of potash, and limestone are also considered Organic Fertilizers.

Examples of manufactured organic fertilizers include compost, blood meal, bone meal, and seaweed extracts. Other examples are natural enzyme digested proteins, fish meal, and feather meal.

Sources Of Organic Fertilizers

Peat, a precursor to coal, offers no nutritional value to the plants but improves the soil by aeration and absorbing water. It is sometimes considered as being the most widely used organic fertilizer and by volume is the topmost organic amendment. Peat is the most widely used as an organic amendment.

#1. Animal Sources  

Animal sourced materials include both animal manures and residues from the slaughter of animals. Manures are derived from milk-producing animals, egg-producing birds, and animals raised for meat and hide production. When an animal is butchered, only about 40% to 60% of the live animal is converted to market product, while the remaining 40% to 60% are considered as by-products.

These by-products of animal slaughter, mostly inedible; blood, bone, feathers, hides, hoofs, horns, can be refined into agricultural fertilizers including blood meal, bone meal fish meal, and feather meal.

Chicken litter, which consists of chicken manure mixed with sawdust, is an organic fertilizer that has been proposed to be superior for conditioning soil for harvest than synthetic fertilizers.

#2. Plant Sources     

Processed organic fertilizers include compost, humic acid, amino acids, and seaweed extracts. Other examples are natural enzyme-digested proteins. Decomposing crop residue (green manure) from prior years is another source of fertilizer.

In a study, it was found that algae which are used to capture nitrogen and phosphorus runoff from agricultural fields do not only prevent water contamination by these nutrients but also can be used as an organic fertilizer.  

Some scientists originally developed the “algal turf scrubber” aimed to reduce nutrient runoff and increase the quality of water flowing into streams, rivers, and lakes, found out that this nutrient-rich algae, once dried, can be applied to cucumber and corn seedlings resulting  in good growth compared  to when  synthetic fertilizers are used.

#3. Treated sewage sludge 

Sewage sludge, also known as biosolids, is an effluent that has been treated, blended, composted, and sometimes dried until considered biologically safe. As a fertilizer, it is most commonly used on non-agricultural crops such as in silviculture or in soil remediation). Sludge is unacceptable due to toxic metal accumulation, pharmaceuticals concerns, hormones, and some other factors.

With concerns about human borne pathogens coupled with a growing preference for flush toilets and centralized sewage treatment, biosolids have been replacing night soil (from human excreta), a traditional organic fertilizer that is minimally processed.

Some natural fertilizers

  • Alfalfa
  • Ash
  • Blood meal
  • Bone meal
  • Compost
  • Cover crops
  • Fish emulsion
  • Fish meal
  • Manure
  • Rock phosphate

  • Wood chips/sawdust

Best Natural Fertilizers For Tomatoes

#1. Compost

A compost pile will produce rich, pure organic matter loaded with essential nutrients and beneficial microbes. It is recommended that a simple compost bin should be piled to help build rich soil.

Compost has all the basic nutrients, both macronutrients, and micronutrients, that are usually absent in synthetic fertilizers.

#2. Epsom Salt

Tomatoes use lots of magnesium while growing; Epsom salt helps provide tomatoes with the necessary amount of magnesium.

#3. Fish Emulsion

This is a natural fertilizer for tomato that gives them an extra boost, both at transplanting and during the growing season.

It is rich in phosphorous, nitrogen, and potassium, as well as other important minerals such as magnesium, calcium (helps prevent blossom-end rot), and sulfur.

#4. Organic Cottonseed Meal

This is an ideal natural fertilizer that can be added as an organic soil amendment at the time of transplanting seedlings. Cottonseed meal is rich in potassium, nitrogen, and phosphorus in a ratio of 6-2-1.

#5. Animal Manures

Animal or cow manure is classic plant food for tomatoes, but before application, several things need to be considered. Pet manures should never be used; cat and dog manures are highly toxic, dangerous to humans, and are full of pathogens. Only manure from vegetarian animals such as horses and cattle should be used excluding chicken manure.

Organic Fertilizers Vs Inorganic For Tomato

There are advantages and disadvantages of organic and inorganic fertilizers. The major benefit of organic fertilizers is that they work slowly. They need to be broken down by soil organisms for their nutrients to be released which take time. Because they work slowly, nothing is wasted. They are consumed as they are released, unlike chemical fertilizers, which are released immediately into the soil.

 Because organic fertilizers contain organic material, they improve the soil’s structure or its capability. Soil that is being fertilized with organic matter is easier to work on and allows more air to get to plant roots. The organic material also permits the soil to retain water for long. Finally, the addition of organic substances used in fertilizer increases the bacterial and fungal activity in the soil. Overall, organic garden fertilizer not only helps plants, it improves the soil also.

Organic fertilizers’ biggest strengths are also their weakness. Because organic fertilizer nutrients are slowly released into the soil, they are not immediately available to plants. If there is an immediate need for nutrients, liquid fertilizers or foliar applications might be considered.

Inorganic fertilizers work faster, which can be beneficial or a disaster depending on your garden’s needs. Another disadvantage of inorganic fertilizer is that overwatering or rain can push the chemicals beneath roots where they won’t do any good. Inorganic fertilizers, because they are so rich, can easily burn roots or create a toxic concentration of salts if over-applied.

Problems Associated With Using Artificial Fertilizers.

  • The possibility of burning plants with the concentrated chemicals from overfeeding the plants.
  • The progressive decrease of the real or perceived health of soil, apparent loss of structure, reduced ability to absorb precipitation, lightening of soil color, etc.
  • The necessity of reapplying artificial fertilizers regularly in increasing quantities to maintain fertility.
  • The cost of acquiring artificial fertilizers.
