Duetto by Hello Nature is created to fertilize crops and encourage quick growth rates among fruits and vegetables in a natural, sustainable manner. Duetto specifically supports crops needing high quantities of potassium in the growing environment for better quality of the yield.

Using Duetto as a fertilizer, it’s possible to improve the quality of soil to help your plants produce more for a better yield. Fruits and vegetables are of better quality with Duetto, because it helps reduce soil exhaustion and helps plants get more nutrients from the ground.  Duetto improves the efficiency of organic nitrogen throughout the plant’s life cycle by reducing the risk of leaching and activates soil microorganisms to enhance plant nutrient uptake. Featuring essential nutrients and containing a large quantity of humified organic and active matter, these compact pellets dissolve into the soil rapidly, improving the structure and water retention of soil, avoiding losses or insolubilization of elements which are so precious to crops. Hello Nature’s organic-based fertilizers are produced from select raw materials that are carefully chosen according to strict parameters.The exclusive manufacturing process guarantees maximum quality and safety, delivering a product which is biologically active, free from weed seeds and pathogens (i.e. Salmonella, Escherichia coli, etc.), and rich in useful micro- organisms such as PGPR (Plant Growth Promoting Rhizobacteria).

Nitrogen (N)
Plays a very important role in various plant physiological processes. It imparts dark-green color in plants, promotes leaves, stem and other vegetative part’s growth and development. Moreover, it also stimulates root growth. N produces rapid early growth, enhances the growth of leafy vegetables, and increases protein content of fodder crops.

Potassium (K)
Is vital for plant metabolism. It helps in the development of a strong and healthy root system and increases the efficiency of the uptake and use of nitrogen and other nutrients. K helps photosynthesis, regulates the water status in the plant and plays an essential part in the formation of starch and in the production and translocation of sugars. K not only increases yields but also enhances fruit quality, improving flavor and color and increasing the size.

Phosphorus (P)
Is essential in photosynthesis and respiration. Seeds have the highest concentration of P in a mature plant, and P is required in large quantities in young cells, such as shoots and root tips, where metabolism is high and cell division is rapid. P aids in root development, flower initiation, and seed and fruit development.

Organic Matter
Primarily composed of carbon, organic matter in soil has direct benefits for agricultural production. Soil organic matter plays a vital part in enhancing soil fertility and quality, on three levels: chemical (capacity to store and supply essential nutrients), physical (improve soil structure and water holding capacity), and biological (enhance biodiversity, improve microorganisms’ activity, and capture carbon).
