Nanofertilizer for sustainable agriculture

The study: Nanofertilizer use for sustainable agriculture: Advantages and limitations, published on the Plant science: an international journal of experimental plant biology, makes a very precise point on what many believe could be the fertilizer of the future.

We can read: "Nutrient fertilization plays a critical role in maintaining soil fertility and improving crop productivity and quality. Precise nutrient management of horticultural crops is a major challenge worldwide as it relies predominantly on chemical fertilizers.

Traditional fertilizers are not only costly for the producer, but may be harmful to humans and the environment. This has led to the search for environmentally friendly fertilizers, particularly those with high nutrient-use efficiency, and nanotechnology is emerging as a promising alternative.

Nanofertilizers offer benefits in nutrition management through their strong potential to increase nutrient use efficiency. Nutrients, either applied alone or in combination, are bound to nano-dimensional adsorbents, which release nutrients very slowly as compared to conventional fertilizers.

This approach not only increases nutrient-use efficiency, but also minimizes nutrient leaching into Furthermore, nanofertilizers but y also be used for enhancing abiotic stress tolerance and used in combination with microorganisms (the so-called nanobiofertilizers) provide great additional benefits.

However, although the benefits of nanofertilizers are undoubtedly opening new approaches towards sustainable agriculture, their limitations should also be carefully considered before market implementation. In particular, the extensive release of nanomaterials into the environment and the food chain may pose a risk to human health.

In conclusion, although nanofertilizers use in agriculture is offering great opportunities to improve plant nutrition and stress tolerance to achieve higher yields in a frame of climate change, not all nanomaterials will be equally safe for all applications.

The risks of nanofertilizers should be carefully examined before use, and further biotechnological advances are required for a correct and safe application of nanomaterials in agriculture."

What is the relationship between fruit and arthritis?

Arthritis is an arthropathy with an inflammatory etiology that can be of different types, more or less severe.

The causes can be of metabolic, autoimmune, infectious or idiopathic origin. The initial diagnosis makes use of a clinical evaluation accompanied by subsequent instrumental investigations. Among the various symptoms that characterize arthritis we find the most common such as heat, swelling, stiffness, pain, redness.

The study: Dietary fruits and arthritis, published on the Food & function, said us: "Arthritis is a global health concern affecting a significant proportion of the population and associated with reduced quality of life.

What is the relationship between fruit and arthritis? Among the different forms of arthritis, osteoarthritis (OA ) and rheumatoid arthritis (RA) are the most common and lacking a definite cure in the affected individuals.

Fruits, such as berries and pomegranates are rich sources of a variety of dietary bioactive compounds, especially the polyphenolic flavonoids that have been associated with antioxidant, anti-inflammatory and analgesic effects.

Emerging research demonstrates a protective role of fruits and their polyphenols in pre-clinical, clinical and epidemiological studies of OA and RA. In this context, commonly available fruits, such as blueberries, raspberries and strawberries, and pomegranates have shown promising results in reducing pain and inflammation in experimental models and in human clinical studies of arthr itis.

There is also some evidence on the role of specific fruit polyphenols, such as quercetin and citrus flavonoids in alleviating RA symptoms. These emerging data deserve further investigation in rigorous scientific studies to determine the mechanisms, dosing and selection of fruits and fruit extracts in arthritis management."
