Humic Acid And Its Uses As Fertilizer

Humic acids are complex molecules formed by the breakdown of organic matters in soil. People think that humic acids are fertilizers but it is not so, it can be added to fertilizers to make soil better even if the soil is less fertile. Humic acids are not fertilizers but in fact, it is more of a soil conditioner. It is the end result of ancient plant and animal matter. The best sources of humic acids are the sedimentation layers of soft brown coal, which are known as leonardite. Humic acids are found in high concentration here. It is rich in organic and mineral substances that are essential for plant growth.

Humic acid, when used along with fertilizers has the ability to make the soil improve its texture and water retention. It increases water holding capacity and breaks down crop residues. It builds organic matters in soil and reduces soil erosion. It also stabilizes soil temperature. Humic acid, if applied to sandy soils, can provide organic matter and help retain water, which is essential for the growth of the plant.

Importance of Humic Acid-

The structure of the soil is improved by humic acids. It prevents high water nutrient losses in light, sandy soil. At the same time converts them into fruitful and fertile soil by way of decomposition. In heavy and compact soils, aeration of soil and water retention is improved. It prevents soil cracking, surface water draining, and soil erosion by increasing the ability of top soil to combine or mingle. Helps the soil to loosen and crumble, thus increases aeration or airing of the soil as well as soil work capacity. It increases water holding capacity of soil, which helps to resist drought. Many times it darkens the color of the soil thus help in the absorption of the sun energy.

Humic acid helps to convert elements to plant food when it is added with fertilizer. It retains soluble fertilizers in root zone of the plant thus strengthens the roots as well as the stem. Has a very high ion exchange capacity. It releases nutrients as needed for the plants and stabilizes nitrogen that is required for the plant and also breaks down salt complexes. When humic acids are used with fertilizer it boosts the growth of the soil life, root growth, plant enzyme and plant growth at all stages.

Importance of Fertilizer in Soil-

Soil conditioner that makes poor soil good and good soil better is possible if humic acid is added to the fertilizers. It works best when added with fertilizer to create optimum growing conditions or the finest growing condition. They work as a compliment to the fertilizer and together, humic acid and fertilizer is more fruitful. Humic substances are similar to auxin growth hormone and improve the living cell metabolism or growth. It provides available carbon to microorganism and is safe to the environment and also to the living organism. It liberates carbon dioxide from soil calcium carbonate and enables its use in photosynthesis. It helps to eliminate chlorosis due to iron deficiency in plants. It reduces the availability of toxic substances in soil and makes the soil better for the crops. It neutralize both acid and alkaline in soil.

Fertilizers are essential for better input in any cropping system and when humic acids are added, it helps to improve the efficiency of the fertilizers by increasing the nutrient value and retention. It can add organic matter to deficient soil and increase chlorophyll synthesis and have better seed germination. It also stimulates favorable microbial activity with an overall better and healthier plants and improved yields. Humic acids with organic fertilizer give abundant natural organic substances and help soil and plant with dense humic acid and can optimize the structure of soil to increase the buffering power and fertility.

There are different types of fertilizers with humic acids, such as humic acid liquid, humic acid powder, humic acid round granule and humic acid flakes. Humic acid in liquid foliar helps the plant to uptake and utilize the nutrients in the solution many times more successfully. It is assimilated more easily by the plants to improve the plant metabolism, immunity, root development and improves the supply of plant nutritional elements and also increases the formation of ferments. It promotes the increased accumulation of chlorophyll, sugar, amino acids and improves the effectiveness of nitrogen consumption.

The greatest and the most important thing is that humic acids helps to increase the plant’s ability or capacity to tolerate the stresses of heat drought, cold weather, diseases, insects, and other kinds of environmental problems. It increases general plant productivity, in terms of yield.


The Hazardous Effect Of Chemical Fertilizer: Organic Fertilizer Is The Only Solution

Plants require a number of soil nutrients like nitrogen, phosphorus and sulfur for their growth.  But, soil nutrient levels can decrease over time when crop plants are harvested, as nutrients are not returned to the soil.  Hence, these essential nutrients needs to be compensated either through the natural process of decomposition, when plants die and decay, and the nutrients extracted from the soil return to the soil or by the easy means of adding fertilizers.

Today fertilizer has become essential to modern agriculture to feed the growing population.
Use of fertilizers, especially, the chemical fertilizers has brought in blessings on humanity, which helped contain hunger and death in different corners of the world.  Though chemical fertilizers increase crop production; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well.  It has already been proved how chemical fertilizers pose serious challenges to the balanced and sustainable growth.  Accordingly, scientists and researchers are seen arguing in favor of organic fertilizers as the best solution to avoid soil pollution and many other threats to environment and life caused by overuse of chemical fertilizers.                                                                                            organic2 copy

Since salt content is one of the most critical characteristics of chemical fertilizers; they are expected to be harmful to agriculture in the long run as salts are harmful for plants as well as soil.  Continuous use of these chemical fertilizers depletes essential soil nutrients and minerals that are naturally found in fertile soil.  When we use chemical fertilizers; they do not help replenish soil nutrients and its fertility contrary to the popular belief; but, replenish only nitrogen, potassium and phosphorous.  And we know phosphorous does not dissolve in water and its overuse may cause hardening of soil.  Likewise alkaline fertilizers like sodium-nitrate develop alkalinity in soil reducing its fertility and making it barren.  So to say; soil fertility and vegetation depend much on the balanced supply of essential nutrients and minerals.  As such, overuse of specific nutrients may cause imbalance in the supply of soil nutrients further resulting in soil degradation and the loss of equilibrium of a stable soil.

Though chemical fertilizers will help plants grow faster; plants will not be healthy and strong as plants grown in that manner do not have enough time to mature to develop a good root growth, strong stems, or nutritious fruits and vegetables.  Even they will be less likely to survive because they will be more susceptible to pests and diseases as they lack good immune system and enough resistance against these forces.  Besides this, chemical fertilizers can cause root burn or fertilizer burn, as chemical fertilizers do not allow enough water intake for the plants.  As already said; chemical fertilizers are high in nitrogen salts, and when the nitrogen is absorbed by soil too quickly; it will dehydrate and dry up the plant. But, organic fertilizers are not like them; they are slow release which will allow time for microbial activity to break down the organic materials in the fertilizers. When we talk of microbial activity; we need to remember that natural microbes; which include beneficial insects, fungus, and bacteria found in the soil, are very much helpful for healthy soil and plant growth.  Needless to say, use of chemical fertilizers will kill these soil friendly micro organisms.

In their larger threat to environment, animals and human health; chemical fertilizers will ultimately end up leaking into our water bodies; ponds, streams, ground water etc and contaminate water supply as a result of which humans as well as animals may suffer numerous short term and long term hazardous chemical effects on their health and body.  In reply to this, organic fertilizers will be the right solution without which gardening and growing healthy and natural food and crops could be possible.

The Importance Of Fish Fertilizer As An Organic Fertilizer

Fish is a highly nutritious food.  It is an excellent source of protein with fewer calories and considered better than other meat options.  It is rich in omega 3 fatty acids which are proven to be good for the heart.  There are many health benefits of eating fish.  Its regular consumption helps reduce risk of various diseases and disorders.  However, apart from these health benefits; fish can also be used to produce fish emulsion a mixture which is considered one of the best organic fertilizers ever created in such a perfect proportion of nutrients plants need most for their healthy growth.  As such, it is beneficial not only for the humans but also for the plants.

A fish emulsion is generally created out of a byproduct of the fish oil and the fishmeal industries.  Obviously, it is natural and organic.  It is a simple process through which fish emulsion is produced using the waste fish samples that are subjected to intense heat by cooking until the muscles as well as the bones are tender enough.  Cooking not only softens the components for utmost extraction but also helps get rid of bad and sharp odor from the rotting fish.  There after few acids like sulfuric and phosphoric acids are added to the mixture only to kill off the decaying odor and help prevent early aging of the product.  Now, the fish emulsion is ready to be used as organic fertilizer in the plants.

Fish fertilizers can also be prepared using cold processed which means the fish is converted through the grinding process and by the naturally occurring enzymes that continually break down the fish into a liquid.  It is said enzymes are still present when you get it; so they are there to keep your soil alive.  Unlike fish emulsion this process does not remove oils.  It is screened through a mesh screen and has the consistency of chocolate milk and is very easy to apply.  This process uses several species of edible fish and has no offensive odor.  However, the fertilizers whether produced through cooking or using cold processed are all natural and organic, and very effective in the over-all growth of the plant.

Fish fertilizer normally contains most important minerals needed by plants.  It is also known to contain traces of other essential nutrients.  That is why; it is capable to promote proper development of the roots of the plant.  This organic fertilizer is observed to be more effective when applied to the plants during the colder seasons, which reduces possible leaf burning.  Other elements that are contained in fish emulsion also contribute towards over-all health of the plant.

Fish fertilizers are good source of nitrogen.  It is usually composed of 5% Nitrogen, 1% Phosphorus and 1% Potassium.  In addition to these three macronutrients, fish emulsion also contains micronutrients and trace minerals.  Fish emulsion makes a fast acting foliar fertilizer.  In fact, today it is one of the most common liquid organic fertilizers.  Tropical plants with large leaves, including Alocasia, Caladium, Calathea, Canna, Colocasia, Ginger, Heliconia and others, benefit from periodic applications of additional nitrogen using fish emulsion.  Leafy vegetables, such as arugula, lettuce and spinach and herbs, like basil and parsley, also respond well to extra feedings of nitrogen.  As such, this mixture is perfect for use in perennial veggies and flowers, for all plants contained in the greenhouse and are best in promoting healthy root systems among plants.  Its application is also believed to have the ability to help plants deter away insects that attack them.

Organic fertilizers are hailed these days due to a number of reasons.  These are commended for their ability to improve the quality of the soil where the seeding is planted. Organic fertilizers also re-emphasize the role of humus and other organic components of soil which are believed to play several important roles.  Further, organic fertilizers help air to move freely within the particles thereby enriching the soil as the nutrients are equally distributed.
