“The most beautiful thing in nature, a flower, has its roots in the earth and in the fertilizer.”
(David Herbert Lawrence)
What is a biofertilizer?
Many farmers are engaged in environmentally friendly agriculture. Alternative solutions, including biofertilizers, are made available to them so that they can successfully grow their crops. A biofertilizer is a product containing living micro-organisms that helps to improve plant growth. In other words, it is a product that optimises soil functions and fertility thanks to the action of the micro-organisms it contains.
To grow, plants need light, water, carbon dioxide (CO2), molecular oxygen (O2) and minerals. Thanks to their root system, they draw these resources stored in the soil, which are necessary for their life and development. However, the soil not only serves as a nutrient reserve for plants but is also a complex ecosystem. Although it has a substantial nutritional capital, a fraction of what is used to feed the plant may be immobilised and therefore not available for it.
This is where soil micro-organisms come into play: they participate in mechanisms to improve the bioavailability of nutrients, thus promoting plant development.
Biofertilizers are therefore products made up of living micro-organisms, which have properties that stimulate plant growth. To help plants, they act in particular on nutrient reserves that are immobilised in the soil or the atmosphere.
The advantages of biofertilizer
The main advantages deriving from the use of biofertilizers can be summarised as follows:
- The best nutrient intake: some nutrients are present in the soil but are not physically available to the plant because they are in a form that cannot be absorbed or because they are physically too far from the roots. Micro-organisms such as phosphorus-solubilising bacteria or nitrogen-fixing bacteria make these elements bioavailable to the plant, thanks to their properties and their action in the soil. Others, such as endomycorrhizal fungi – which have the property of being in symbiosis with the plant, so that each of the two organisms benefits from the other – indirectly widen the root network to bring nutrients closer to the plant. Through their actions, biofertilizers make it possible to directly or indirectly improve the absorption of nutrients by the plant, which leads to an optimisation of its growth and development;
- Resistance to abiotic stress: micro-organisms have a positive effect on the nutritional status, growth and environment of the plant. These improvements allow crops to become more resistant to the various abiotic stresses that surround them: trampling, drought, salinity, heat, etc.
- The improvement of soil activity: biofertilizers have the capacity to rehabilitate and improve soil functions and natural systems, using the resources of nature. By bringing living micro-organisms into the soil, their biological activity is revitalised.
CHARACTERISTICS OF BIOLOGICAL AZOTATED FERTILIZER
- PHYSICS PROPERTIES: Fit favoritizes the aggregation and the stabilization of the particles in the land. It reduces the superficial erosions, the clay compaction of the land, the creation of the scabs in the silty land and the consequences of the superficial water’s run off. It gets better with the hydric retention in the sandy land.
It makes the land more workable because it maintains stable temperatures;
- CHEMICAL PROPERTIES: it increases the capacity of the cationi switch in the land and the capacity of hydric retention. It’s also able to from stable complexible not dilavables with the macros and the oligos nurtures, these ones increase the characteristics quality of the agricultural products contributing to reduce the lost of the micro nurturing, the potential toxicity of the metals and of the phytosanitary products, but also to maintain in the assimilable form some ions that otherwise would stay fixed on the land. It also contributes to the capacity of tampon with the acidifying agents continuing to maintain the PH and the natural values of the land.
It reduces the greenhouse gas emission in the atmosphere and favoritizes the accumulation of the CO2, tying the azotate, for the colloidal nature of the humus that forbids the escape of the ammoniac in the atmosphere.
- BIOLOGICAL PROPERTIES: FIt favorizes the metabolic energy that is necessary for the biological process. It favors enzymatic activity and increases the number of species improving biodiversity in the lands.
It makes available gradually the nurturing elements (azotate, phosphorus and sulfur) to the living organisms in the land. It increases the resilience of the land.
