Microbes In Agriculture And Their Role In Plant Growth Promotion
With the world population growing, the agricultural sector is facing an unprecedented challenge to raise productivity and feed billions. Additionally, climate change and excessive use of chemicals have impacted the environment and human health.
Excessive chemical usage and misinformed farming practices have a drastic effect on our natural resources as well the quality and quantity of yield that most farmers achieve today. For the past two decades, Organica Biotech with world-class experience and extensive research have developed solutions for sustainable farming, plant growth and soil conditioning. The high quality, eco-friendly and innovative products like plant growth promoters help to increase yield and productivity under optimal and sub-optimal conditions.

Billions of microorganisms in the complex plant ecosystem play a vital role in the growth and health of plants. Microbial biostimulants boost crop productivity, nutrient uptake and resistance against pests and abiotic stresses.
Biostimulants can be defined as a mixture of natural substances or microorganisms that promotes plant growth without any side-effects. The natural preparations consist of various natural extracts, beneficial fungi and bacteria, enzymes, proteins, amino acids, micronutrients, etc.
Plant growth promoters that act as microbial biostimulants have multi-faceted benefits when it comes to overall plant health, growth and resulting productivity. They are more intertwined than we believe. Some of the beneficial attributes include:
Plant growth regulation & enhancement
Plant Immunity & resistance against disease-causing microbes & insects
Plant Growth Enhancement
Maintenance of Soil Fertility
Resistance to Abiotic stress
Biofertilizers are microbes that when applied to the plant, promote growth by improving the bioavailability of nutrients to the host plant. Biofertilizers add nutrients through natural processes by stimulating the synthesis of enzymes that help the plant absorb the nutrients it requires. This improves nutrient assimilation and thus has a direct positive impact on plant growth and productivity. Biofertilizers are the most well-known categories of microbial biostimulants.
- Plant growth regulation and enhancement
Microbes and plants have always grown in perfect symphony with each other with the progress of evolution. Scientists have found that microbes have evolved to produce important plant growth and metabolite regulating hormones as well. Their presence or absence in and around the plant can be crucial in the role they play as plant growth promoters.
- Plant Immunity & resistance against disease-causing microbes & insects
Microbes form the first of defence against the onslaught of microbial pathogens and pest insects. They boost the crop’s immunity in resisting infection. This can be directed by helping the plant produce beneficial compounds that do not allow infections / repel infestation causing insects, or indirectly by strengthening the plant with better nutrient assimilation and stronger growth responses.
- Maintenance of soil fertility
Soil fertility is the most critical component to the growth of a plant. Sustainable agriculture techniques are incomplete without understanding how one can preserve or enhance the biological and chemical fertility of the soil. Microbial biostimulants also perform the function of improving the organic carbon conditioning of the soil, which is very important to soil health.
- Resistance to Abiotic Stress
Various abiotic stress factors like soil composition, salinity, acidity, temperature, drought, humidity, rain, wind adversely affect plant growth, yield and agriculture in whole. These factors make plants to use their existing energy reserves to reduce the stress and thereby resulting in poor yield. This is where microbial biostimulants come in and demonstrate effectiveness against abiotic stress and further helps in enhancement of nutritional uptake and plant metabolism.
Advantages of plant growth promoters or microbial biostimulants in agriculture include better yielding and increased size of plants and fruits. It influences the physical characteristics of the plants and their chemical composition as well.
Effective microbial biostimulants affect a multitude of biochemical processes occurring in the soil and plant, which allows for the achievement of overall improvement in health and productivity. Microbial biostimulants influence properties like dry mass, acidity and vitamin content of fruits and vegetables. This in turns affects their shelf life, quality and other attributes as well.
At Organica Biotech, our motto is to provide farmers with highly innovative plant growth promoters
or microbial biostimulant products that enhance soil productivity and crop vigour, naturally and effectively, resulting in better yields.
We supply technology-driven products worldwide and have consistently strived towards meeting our objectives of promoting sustainable agriculture. Our range of Magic Gro products contains highly beneficial microbes that can adapt to different geo-climatic conditions and maintain a healthy ecological balance in the soil. It also helps boost crop vigour, enhance immunity against biotic and abiotic stress and thus boost overall crop productivity. For sustainable farming and holistic plant growth promotion, use microbial biostimulants and reduce your impact on the Earth’s natural resources.
