Organic Fertilizer and It’s Hidden Value

An organic fertilizer is a scientifically blended product consisting of biodegradable waste materials e.g. plant and animal wastes including garbage and sewage wastes fortified with chelated trace materials, enzymes, growth promotants, phyto-vitamins, probiotics, amino acids, organic acids and billions of beneficial microorganisms. Functional compounds such as chelating agents, surfactants, emulsifiers and stabilizers are added and mixed thoroughly with the biomass to ensure better quality and efficacy as well as enhanced assimilability of the nutrients contained in the finished product.

The hidden values of the organic fertilizer that we produce include the following:

  1. It is an excellent soil conditioner, making the soil more friable. In other words, it provides the soil good tilth.
  2. It enhances the cation exchange capacity (CEC) or nutrient binding capacity of the soil.
  3. It can also enhance the growth of soil microorganisms that help released elements for plant use.
  4. It enhances nitrogen fixation. This translates into substantial savings on chemical-based nitrogenous fertilizers.
  5. It can enhance the formation of growth promoting substances advantageous to plant growth.
  6. It is the source of organic acids that can improve the assimilability of soil minerals by plants.
  7. It can beneficially affect the chemistry of inorganic fertilizers in the soil minimizing their degree of mineralization.
  8. It enhances the moisture retention of the soil by increasing its water holding capacity.
  9. It minimizes sharp fluctuations of soil temperature, hence, minimizing the stress in plants attributable to wide gaps of daytime and night time temperature and last but not least.
  10. It promotes soil-balancing effect. The soil where the plant grows must be in an ideal balanced site: physically, chemically and biologically for maximum productivity.

Microbes on fertilizers play a critical role on the plant yield and increase in harvest and production? On the average, an ordinary organic fertilizer can only has 5 to none microbes and can only increase yield up to 3.4% to 8.1%. Our PLANTMATE ORGANIC FERTILIZER has 25 microbes and is proven to increase yield by 30%-50% has balanced composition of beneficial microbes with chelated trace elements, growth promotants and balanced micronutrients which are readily assimilable by the plant and thus, it is indeed the most superior organic fertilizer compared to others. These 25 microbes were discovered through the years of our research, and now plays a significant role on increasing yield.

Advantages of Plantmate Organic Fertilizer Relative to Chemical or Inorganic Fertilizer

  1. It is cost beneficial. Plantmate Organic Fertilizer (POF)- a superior product which is produced by using Bio-PLUS Activator, a biological preparation consisting of 25 beneficial microbes, enzymes, growth promotants, amino and organic acids, probiotics and functional compounds that enhance nutrients assimilation by plants is very much cheaper compared to chemical or inorganic fertilizers. Since it is locally produced, it saves the country of much needed foreign currency.
  2. It is an excellent soil conditioner. POF when applied to the soil will make it loose and friable. In other words, it provides the soil good titlth- a condition that will encourage more vigorous and profuse growth of root hairs as well as deeper and wider root zone of the plants or crops. On the other hand, chemical fertilizers will cause puddling of the soil making it tough and difficult to prepare making it more costly for land preparation.
  3. It enhances the cation exchange capacity (CEC). The CEC refers to the nutrient binding and storing capacity of the soil. The greater the CEC the more nutrients can be stored in the soil hence, supply of nutrients to plants will not be limited and therefore encourage better growth and development and higher yield. The CEC of POF can be as much as 300 meq/gram of soil so its ability to store nutrients can be as much as 6 times that of plain compost.
  4. The use of POF builds up the organic matter content of the soil. Since the organic matter is the natural food source of beneficial soil microorganisms their proliferation will therefore be enhanced. These beneficial microbes will convert inorganic elements into “metabolites” or organic compounds that can be easily assimilated by plants. Also the microbes will accelerate the decomposition of organic materials e.g. grasses, weeds and stubble. Chemical fertilizers do not contain organic material, hence they don’t improve the organic matter content of soils.
  5. It promotes nitrogen fixation as well as that of the other major elements. POF contains at least 7 microbes that are N-fixers as well as other species that can convert phosphorus, potassium and other inorganic elements available in the soil into readily assimilable compounds for plant use. This translates to substantial savings on chemical fertilizers. NPK which are generally supplied by chemical fertilizers are expensive and since they are oil-based products their prices have become very prohibitive.
  6. The POF also contains beneficial microbes that have the ability to produce natural enzymes. This will encourage the formation of growth promoting substances for better growth. Some microbes also produce probiotics (precursors or source of penicillin, terramycin, aureomycin, bacitracin, polymixin, etc. that will protect and/or increase the resistance of plants against bacterial-, fungal and viral-borne diseases.
  7. It is a good source of organic acids that can improve the assimilability or absorption of soil minerals by the plant. Increase assimilation will mean additional savings. On the other hand, losses of nutrients from chemical fertilizers can be as much as 70% since they are highly volatile and not as stable as organic nutrients. Also the organic acids founds in the organic fertilizer (e.g. humic formic, acetic, citric, stearic, oleic etc.) when absorbed or assimilated by plants will render them resistant to attack of pets and secondary diseases. This means substantial savings on pesticides which are harmful to humans and animals and cause damage to soil, water and air.
  8. It can beneficially affect the chemistry of inorganic fertilizers in the soils minimizing their degree of immobilization. The beneficial microbes will transform the insoluble inorganic elements supplied thru chemical fertilizers or those found in the soil into metabolites or highly assimilable nutrients ready for plant use.
  9. It improves the water holding capacity of the soil. Since the POF contains substantial amounts of humus – a material that can absorb water three times its weight, soils fertilized with it will retain more moisture – a condition which is significant especially during droughts or prolonged dry season. Humic acid which is found in humus is also beneficial for plant growth and development. Chemical fertilizers do not have a trace of humus.
  10. The POF minimizes sharp fluctuation of soil temperatures, hence, minimizing the stress in plants or crops which is attributable to wide gaps of daytime or night time temperatures. The growth and yield of plants or crops subjected to any stress will be adversely affected. Again, chemical fertilizers do not have the ability to provide this advantage.
  11. Last, but not the least, the POF promotes soil balancing effect. The soil where the plant grows much be in a well-balanced state: physically, chemically and biologically for maximum productivity. It is only through the use of a superior organic fertilizer such as the POF that this state can be achieved. Since organic fertilizers do not destroy the soil, it will eventually lead to sustainable production.

Advantages of Organic over Chemical Fertilizers

The following features can be cited why the use of organic fertilizers in our soils must be encouraged either singly or preferably in complementation with inorganic fertilizers.

  1. Cost Savings – It has been demonstrated in the growing of various crops that a combination of organic and foliar fertilization supplemented with adequate chemical fertilization is less expensive and resulting in better production than chemical fertilization alone. The techno-demo tests conducted in selected areas throughout the country by the Bureau of Soil and Water Management revealed that a savings of about P1000.00 per hectare is realized when complementation of organic and inorganic fertilizers are applied by rice farmers.
  2. Ecological Consideration – Chemical fertilization results into depleted and acidic soils. Growth of beneficial organisms is adversely affected when soil turns acidic and the biological activity slows down. Biologically inactive soils decompose organic matter much slower than soils with adequate amounts of decomposed organic matter which is the natural habitat of beneficial microorganisms. The conversion of nutrients into their assimilable form also slows down when bacterial population is reduced.
  3. Dollar Savings/Import Substitution – Imported chemical fertilizers are substitutable by properly and scientifically produced organic and mineral-based liquid fertilizers which can be produced locally, hence enabling the country to save on foreign exchange otherwise spent for importation. Dollar Savings/Import Substitution – Imported chemical fertilizers are substitutable by properly and scientifically produced organic and mineral-based liquid fertilizers which can be produced locally, hence enabling the country to save on foreign exchange otherwise spent for importation.
  4. Waste Utilization – Wastes which are abundant in the country such as rice hull and straw, sawdust, leaves, cane bagasse and mud press, grasses and weeds, animal wastes such as pig, poultry, livestock, guano, including human waste and garbage can all be recycled and converted into organic fertilizers. These will totally discourage pollution and prevent the poisoning of our soil and underground potable water. Recent findings showed that many areas in the country especially those applying substantial amounts of chemical fertilizers contain high amounts of nitrates, a carcinogen or cancer-causing substance. Organic fertilizers are environment friendly and a sure way of preserving MOTHER EARTH.

Difference between Plain Compost VS. Organic Fertilizer

Fact: Plain compost and the real organic fertilizer are essentially two different products as shown in the following table:

Plain Compost
Superior Organic Fertilizer
1. The total NPK is low below 4%. Contains only the elements naturally present in the substrate/raw material. Hence, there are not enough nutrients to support proper growth and development of the crop.1. Has a total NPK content of 7.5-8.0% based on 25% moisture content. Adjusted to 10% m.c. this is equivalent to about 15%. Also contains chelated trace elements to effect a graduated release for more efficient utilization by plants
2. Because of the low or inadequate amounts of nutrients, the effect on plant growth and development is inefficient and yield is adversely affected. Note: The law of limiting nutrient in plant nutrition states: "the yield of a given crop is limited by the deficiency of one element even though all of the other necessary elements are present in adequate amounts." by J. von Liebig

2. The finished product is analyzed and must be ensured to contain all the necessary elements in their right ratios as well as in a well-balanced state. For example:

C:N not >15;

C:P not >300; C:K not >150;

C:S not >200; Ca:B not >200;

Ca:Mg not >100; etc.

These nutrients must be readily assimilated by plants to attain maximum productivity.

3. May emit foul or obnoxious smell which is normally the complaint raised by farmers. This is due to incomplete or improper composting. The micro organisms usually pathogenic which produce the bad odor are not killed because the temperature during composting is not high enough.3. Devoid of any foul smell or bad odor. All pathogenic organisms are eliminated because of high composting temperature. Species of bacteria in the BPA will use up the elements that my lead to obnoxious gas emissions e.g. sulfur in hydrogen sulfide and carbon in carbon dioxide, etc.
4. Very difficult to apply because of improper moisture content either too dry or too wet. The texture is not also uniform and sometimes due to carelessness of the processor may contain foreign matter e.g. plastic, stick, stones etc.4. The moisture content is maintained at about 25% which is just right for manual application. In mechanical application the moisture content ranged between 15-20% depending on the machine being used. The material is being sieved to maintain uniformity.
5. Due to insufficient processing temperature normally below 60 degree Celsius weed seeds are not eliminated and this has caused discouragement to farmers.5. The processing temperature would reach thermophilic range (65+/-5 degree Celsius) which guarantees the elimination of all weed seeds and unwanted matter including pathogens
6. The cation exchange capacity (CEC) is low affecting the availability of nutrients for the plants. Note: The CEC is a measure or indication of the soil’s capacity to retain nutrients and make them available for plant use.6. Has a very high CEC, as much as 300 meq/g of soil. In layman’s terms an organic fertilizer with a high CEC has a huge reservoir of nutrients available for plat use.
7. There is truth to the observation that compost in terms of nitrogen content is more expensive than chemical fertilizer pound for pound. For example: If it contains 2% nitrogen, a 50-kg bag would only have at most 1 kg of N and if a bag sells for P200.00, a kilo of N will be worth P200.00. On the other hand, a 50-kg bag urea which cost P900.00 contains 22.5 kg of N, hence a kilo of N amounts to only P40.00.7. Plantmate Organic Fertilizer contains about 2.5% nitrogen so in a bag of 50 kg there is 1.25 kg of N. However, this organic fertilizer also contains nitrogen fixing bacteria, 7 of them and at least 3 species of N-fixing fungi. Note: If a soil has a sufficient amount of organic matter (5-10% within the first 40 cm of top layer) these N-fixer can fix N between 300 kg up to as much as 3000 kg per hectare per year. This is no mean amount and what is good about it, it’s FREE.
