Why is it interesting to associate Bacillus with a supply of Silicon for cultivated plants? The association between bacteria of the genus Bacillus and a supply of silicon can be beneficial for cultivated plants for several reasons. First of all, silicon is an important element for the growth of plants, as it strengthens their immune […]

How can Azotobacter naturally replace synthetic nitrogen units? Azotobacter is a bacterium that can fix atmospheric nitrogen and convert it to a form usable by plants. This ability is due to the presence of an enzyme called nitrogenase, which converts atmospheric nitrogen into ammonia. Nitrogen is a crucial element for plant growth, but plants cannot

The organic matter content of soil has reduced by 1 to 2% in 30 years. This decline has led to the decrease in organic soil fertility and agricultural productivity. To offset this decline in soil fertility, large quantities of inputs have been used. Agricultural productivity can be improved once again only by changing farming practices

The risks of nitrate leaching into water, fluctuations in the global prices of granulated urea and the high level of energy consumption in the production of ammonium nitrate are all reasons that urge us to seek alternatives to the sole use of chemical mineral fertilisers as a source of nitrogen fertilisation for plants. Enriching soil

In addition to covid 19, the year 2021 is marked by awareness of the environment and general health. Consumers, politicians, and farmers in turn raise the multiple issues facing society. Among these issues: environmental imbalances that impact the health of living things, including that of humans. Fertilization plays a major role in soil balance, environmental

Urea 46: a nitrogen fertiliser used worldwide   Urea 46 is the most used nitrogen-based fertiliser worldwide in terms of tonnes due to its high nitrogen content. Industrially synthesised from ammonia and carbon dioxide, the finished product in the form of granulated or prilled urea contains the elements carbon, oxygen, hydrogen and nitrogen. The gradual mineralisation

Adopting organic farming practices for your fields or garden means encouraging plant growth without using most synthetic chemical products. Based on respect for the universal life cycle, fertilisation in organic farming should help plants rather than act as a substitute for nature, and has emerged as a response to consumer trends towards sustainable farming.  

For the last few decades, plant fertilisation has been based on 3 components: The analysis of the soil and its compounds, pH, levels of NPK nutrients The crop’s physiological needs in terms of nitrogen, phosphorus and potassium for growth The NPK nutrients to input in the form of fertiliser to bridge the gap between crop

The many functionalities of silicon make it a fundamental element for plants in their strategies to fight against diseases and pathogens. After oxygen, silicon is the most abundant element in the earth’s crust, yet it is only present in small quantities in living matter. Indeed, these origins make it an element that is difficult to

Soil is said to be poor when it is not able to produce nutrients such as essential microorganisms for humans, plants and animals, and this for generations. Unfortunately, it is not uncommon to see acidic soils poor in humus and organic matter. Therefore, it is high time to reconsider the earth as the fundamental link
