Silica is the scientific name for a group of minerals made of silicon and oxygen. Silica is found in most mineral deposits in the world in both crystalline and non-crystalline (amorphous) forms. Crystalline silica has its oxygen and silicon atoms arranged in a three-dimensional repeating pattern. Amorphous forms of silica have a random pattern. In general, silicon forms can be grouped into three main categories, namely; total, extractable (amorphous) and soluble. The amount of Si in soil may vary considerably from 1 to 45 % Most Si is present in the soil as insoluble oxides or silicates, but...

Das Wachstum von Nutzpflanzen hängt stark von der Verfügbarkeit von Stickstoff ab, der von den Pflanzen vorwiegend in Form von Nitrat aufgenommen wird, das bei den meisten Arten in den Blättern zu Ammonium unter Bildung von Aminosäuren und Proteinen reduziert wurde. Menschen und Tiere sind auf das von Pflanzen gebildete Protein angewiesen. Daher ist der Einsatz von mineralischen N-Düngern für die Ernährung der Weltbevölkerung unerlässlich, aber er ist auch mit Risiken wie einer erhöhten Nitratkonzentration in den essbaren Pflanzenteilen verbunden. Die Toxizität von Nitrat ist...

La croissance des cultures dépend fortement de la disponibilité de l'azote, qui est absorbé par les plantes principalement sous forme de nitrate qui, pour la plupart des espèces, se réduit dans les feuilles à de l'ammonium pour former des acides aminés et des protéines. Les humains et les animaux dépendent de la protéine construite par les plantes. L'utilisation d'engrais azotés minéraux est donc essentielle pour nourrir la population mondiale, mais elle est également associée à des risques tels que l'augmentation de la concentration de nitrates dans les parties comestibles des...

Partial acidification through organic acids has the potential to increase the release of phosphorus from rock phosphates, especially oxalic acid due to the acidic effect and chelating interactions with the metal associated with phosphorus, which results in the available form of phosphorus and other nutrients for plant nutrients uptake. Combination with oxalic acid plus ammonium thiosulfate and mixing them with rock phosphate has an effective effect on increasing the yield parameters of both soybean and maize plants. The use of oxalic acid and ammonium thiosulfate represents many unique...

Selenium (Se) is an essential micronutrient for both human and animals. Plants serve as the primary source of Se in the food chain. Se concentration and availability in plants is influenced by soil properties and environmental conditions. Optimal Se levels promote plant growth and enhance stress tolerance, while excessive Se concentration can result in toxicity. Se enhances plants ROS scavenging ability by promoting antioxidant compound synthesis. Se-dependent antioxidant compound synthesis is critically reliant on plant macro and micro nutritional status. As these nutrients are fundamental...
