According to the ‘fertilizer law’, 12 elements can be seen as essential to crops. However, when analyses are performed on plants in their natural habitat, over 60 different elements can be found.
It is known that there definitely are several ‘missing elements’ that positively effect a crop. Examples are:
Selenium is involved in a plant’s process of photosynthesis. Especially the ultraviolet part of light can be taken in better when selenium is present within the plant. Due to selenium, a conversion process of light to energy could take place, which is perceived to support the plant’s photosynthesis.
Silicon’s popularity is rising. The plant’s ability to ‘build in’thiselement, ensures stronger cell walls. Besides, a better intake of calciumin the plant is established thanks to the addition of silicon. Even though, the intake of calcium improves,the concentration of potassium should be monitored closely. In the end, silicon has indicated to lead to a firmer plant with a better resistance.
Also, the advantages of the use of seaweedand algae areseen. Because seaweed is grown in the ocean, it contains several elements. In addition, seaweed consistsofnatural matter that enablea better resistance against drought. An attempt is done by the salty ocean water to extract the seaweed’s moisture, which is impossible due to the mannitol in the weed. Also (glycine) betaine is a matter that can be found in seaweed. Because of (glycine) betaine,a plant is able to maintain its moisture better. When matters like mannitol and (glycine) betaineare taken in by a plant, its resistance of stress will be affected positively. The use of ‘missing elements’When ‘missing elements’ are used, several things should be taken into account.
