Traditional fertilizers waste a lot of nutrients. Plants absorb very little, meaning farmers must use large amounts repeatedly, which wastes time, money, and harms the environment. Biological liquid fertilizers (made with beneficial microbes) are a greener option, but they have problems too: the microbes often don't survive long, different strains can fight each other, and the products have a short shelf life.
The Solution
This invention introduces a new type of eco-friendly biological liquid fertilizer. Its key innovation is coating the beneficial microbes inside tiny protective shells called hydrophobic microcapsules made from natural materials like corn starch, glycerol, and sodium lignin sulfonate. These capsules are mixed into a liquid fertilizer blend that includes amino acids and plant nutrients.
What’s New and Different
Unlike regular fertilizers, the microbes here are shielded from harsh environments, preventing them from dying off quickly or attacking each other. The use of corn starch and stearic acid makes the capsules water-resistant, controlling when and how microbes are released to the plants. This extends the fertilizer’s shelf life and improves how well it works.
The Benefits
- Higher microbial survival rates — fertilizers stay effective for months, not days.
- Better nutrient absorption — plants grow faster and healthier.
- Less waste — fewer applications needed, saving farmers time and money.
- Eco-friendly — biodegradable ingredients protect soil and water quality.
- Integrated nutrition and watering — simplifies farming operations.
Broader Impact
This invention supports sustainable agriculture by reducing chemical overuse, enhancing crop yields naturally, and helping farmers transition to greener practices. It could play a vital role in improving food security while protecting the environment for future generations.
