Overview of a UMH Initiative in Elche
A project led by Miguel Hernández University in Elche, Alicante, is exploring a new class of fertilizer pills. These tiny biodegradable tablets bring together microorganisms with nutrient-rich materials containing nitrogen, phosphorus, and potassium. As they break down slowly, they release nutrients gradually, supporting plant growth over an extended period.
A researcher from the Department of Agricultural Chemistry and Environment explains that these pellets are part of the European-funded Eco-bio-fertilizers initiative. The goal is to move from pilot ideas to real-world use, positioning the pellets as an effective alternative to conventional commercial fertilizers.
The expert notes that, beyond a smaller ecological footprint, the slow decomposition of the pellets means plants receive nourishment gradually. This sustained release can reduce the frequency of fertilization while ensuring crops receive a steady supply of essential nutrients.
Alternative to Polluting Practices
The pellets are envisioned as a reference point for sustainable fertilization. They aim to replace more polluting methods, such as certain waste-derived or pruning-based fertilizers, which are often burned. Incineration emits greenhouse gases and contributes to climate change.
The Elche-based researcher highlights that improving pellet quality involves carefully introducing selected microorganisms and shaping them into compact tablets. Each pellet concentrates nitrogen, phosphorus, and minority components that enhance nutrient availability for plants.
Additionally, the project seeks to reduce reliance on chemically synthesized fertilizers by offering a viable alternative that can either replace or complement existing products.
Adaptation for Different Soils and Crops
The study notes that pellet composition can vary according to soil type and the crops grown. In total, there are up to fifteen different formulations designed to suit diverse agricultural needs.
During the pellet formation process, application dosages are adjusted by blending microorganisms with nutrient-rich constituents to match soil and plant requirements.
This approach achieves a slow assimilation, or gradual dissolution, which supplies crops with the nutrients they need over time. The rationale is straightforward: steady nourishment supports healthier, more resilient plants.
Some inputs within the pellets come from agricultural byproducts such as the olive washing residue known as alpechín, residues from almond pruning, and organic manure from goats and cows. These elements are incorporated into the nutritional profile to enhance overall effectiveness.
Involving Worms in the Nutrient Cycle
While not a formal part of the European-funded project, researchers are also examining the role of earthworms in the system. Earthworms can help break down plant waste and boost enzymatic activity, contributing to macronutrient cycling and soil health.
The team notes that these creatures help maximize nutrients and reduce toxic elements in manure, effectively improving the fertilizer’s impact on crops.
There is ongoing interest in whether worms can also help degrade microplastics, with early studies suggesting that earthworms may eliminate a portion of these materials over time. This line of inquiry reflects a broader effort to understand how soil life can contribute to cleaner, more sustainable farming practices.
Further information about the environmental research group highlights ongoing work in this area and the potential for broader agricultural benefits.
