Liquid Biofertilizer vs. Solid Biofertilizers: Storage Considerations

Importance of Proper Storage for Biofertilizer Longevity

Liquid biofertilizers require proper storage to ensure efficacy is maintained, and here are tips to ensure biofertilizers are stored properly. 

• Liquid biofertilizers are best kept close to room temperature while solid biofertilizers are best stored under 20 degrees. Ideally biofertilizers are best kept in dry cooling environments. Keeping solid biofertilizers in cooler environments such as 5-20 degrees also ensures efficacy is maintained. 
• Air tight containers are also beneficial to both solid and liquid biofertilizers. Without air entry, biofertilizers are less likely to be exposed to moisture and air degradation. 
• Liquid biofertilizers have sensitive microbial strains that can be negatively impacted from exposure to sunlight. For solid biofertilizers, prolonged exposure to sunlight can diminish the effectiveness. 
• Loss in biofertilizers potency are often monitored over time along with they ability to enhance soil and improve plant growth. Regular assessments of stored biofertilizers ensure they are monitored properly and their effectiveness is maintained.

The Science Behind Biofertilizer Shelf Life and How to Maximize It

Preserving microbial life is crucial in maintaining biofertilizers’ efficacy because microorganisms play an essential role in sustaining soil health and biofertilizers significantly aid in this process. Biofertilizers function specifically by increasing microbial activity in soil, mainly through symbiotic bacteria, fungi, and algae. Some bacteria aid in N-fixation as well. These microorganisms, however, require particular environmental conditions in order to thrive. In this part, we contemplate the importance of environmental conditions that biofertilizers deserve to be safeguarded and held in.

Microbial Life in Biofertilizers and Its Sensitivity 

• Importance of Biofertilizers: In the biofertilizers’ life cycle, microorganisms ameliorate the soil, and in return, biofertilizers derive their nourishment. With proper environmental conditions, biofortilizers can operate with the aid of light to some extent. Nevertheless, while exposed to high levels of humidity, light, or warmth, these microorganisms face enduring damage that proves fatal for low amounts of these environmental conditions.
• Microbial life is the backbone of biofertilizers: when their life span ends, in the absence of enough nourishment, the biofertilizer set to aid perish and simultaneously lose its potency. In the absence of requisite conditions, biofertilizers will no longer have the potency which is essential for high-performance agriculture to thrive.
• Microbial Survival and Shelf Life: The effectiveness and potency of biofertilizers and their shelf life are directly dependent on microbial life. In order for biofertilizers to retain their potency, they must be stored in conditions that sustain microbial life. If they are stored under unsuitable conditions, the active microorganisms capable of providing the intended benefits to plants, soil and crops greatly reduces in number.

Liquid Biofertilizer Shelf Life vs. Granular Biofertilizers

Optimal Temperature and Humidity for Biofertilizer Storage

• Storage Conditions temperature: Biofertilizers require the correct temperature to maximize their shelf life, especially liquid biofertilizers. For biofertilizers, the optimal temperature range is between 4 to 15 degrees Celsius. In particular, liquid biofertilizers are sensitive to temperature changes. In addition, higher temperatures e.g. above 25 degrees Celsius, leads to higher microbial respiration and biosynthesis.
• Controlling Humidity Levels: In addition to temperature control, humidity control is equally important. For solid biofertilizers, excess moisture leads to clumping, which lowers microbial effectiveness. Liquid biofertilizers can spoil entirely. For effective storage biofertilizers should be kept between 40-60% humidity.
• Preserving biofertilizers from sunlight is also essential: Ultraviolet rays are very harmful to the microorganisms encapsulated in liquid and granular biofertilizers. Also, light makes sensitive biofertilizers react even faster, hence, making them less effective.

Best Practices for Storing Biofertilizers and Liquid Biofertilizer

Your biofertilizers can be best utilized only when they are stored correctly. Loss of microbial activity due to incorrect storage will cause a biofertilizer to be useless. Correct practices in storage can aid in maintaining the shelf life of biofertilizers and liquid biofertilizer and support the desired potency for thriving plants.

Ideal Storage Conditions for Biofertilizers 

• Temperature Control: Like all other farm inputs, biofertilizers, both in liquid and granular form, are highly temperature sensitive. They should be kept in cool, dry places, sheltered from sunlight. Liquid biofertilizers and number of microorganisms contained in them are best preserved when the temperature is kept between 4 degrees celsius to 15 degrees celsius. Temperature in this range slows the microbial life in biofertilizers from dying too quickly.
• Humidity Levels: Administering the right levels of humidity is crucial in sustaining the shelf life of biofertilizers. Excess moisture in liquid biofertilizers may lead to spoilage while solid biofertilizers are subjected to moisture, increased deteriorative microbial activity. To keep the biofertilizer effective, the storage environment should have relative humidity of 40-60%.
• Protection from Light: Light and ultraviolet radiation in particular, are known to damage both microorganisms and the fine structure of the biofertilizers. Store biofertilizers in opaque or light resistant containers to maintain them for longer periods. Dark, cool rooms are ideal for storing them, away from light.

Liquid Biofertilizer Storage Tips for Optimal Effectiveness
