The operator can easily monitor the levels of nutrients, such as ammonia, nitrate, phosphorus, potassium, sulphate, calcium, and magnesium. There are three lengths available - 30cm, 60cm and 90cm.\u003c\/p\u003e \u003cp\u003eThe ceramic tip of the lysimeter can be used in all types of soil. It is made of a material that does not react with the nutrients in the soil. Therefore, the soil solution collected is not affected by the chemical composition of the ceramic cap resulting in precise and reliable tests.\u003c\/p\u003e \u003cp\u003eThe HI-83900 allows the extraction of a solution from the soil by creating a vacuum inside the sampler tube. Typically, a vacuum of about -60 centibar should be drawn.\u003c\/p\u003e \u003cp\u003eFor better monitoring of soil solution composition throughout the entire crop growth period, at least two lysimeters should be installed in the root zone of a representative plant, one at the upper part and one in the lower part of the root zone.\u003c\/p\u003e \u003cp\u003eFor better measurement accuracy and repeatability, it is recommended to replicate installations in at least two more locations.\u003c\/p\u003e \u003ch3\u003e\u003c\/h3\u003e \u003ch3\u003ePlant nutrition\u003c\/h3\u003e \u003cp\u003eThe three elements that are most needed by plants are nitrogen (N), phosphorus (P), and potassium (K).\u003c\/p\u003e \u003cp\u003eNitrogen is indispensable for the plant’s life and is a key factor in fertilisation, nitrogen allows the development of the vegetative growth of the plant; in particular, it contributes to lengthening of trunks and sprouts and increases the production of foliage and fruits. An excess of nitrogen weakens the plants structure creating an unbalanced relationship between the leaves and the stalks. In addition, the plant becomes less resistant to diseases.\u003c\/p\u003e \u003cp\u003ePhosphorus is an important element in the composition of DNA and RNA, the regulators of the energetic exchange (ATP and ADP), as well as the reserve substances in seeds and bulbs. It contributes to the formation of buds, roots, blooming, and lignification. A lack of phosphorus results in stifling of plants, slow growth, production reduction, smaller fruits and a lower expansion of the roots.\u003c\/p\u003e \u003cp\u003eEven though potassium is not a constituent of important compounds, it plays a remarkable role in many physiological activities in plants like the control of cellular turgor and the accumulation of carbohydrates. It increases the size of fruits, their flavour, as well as yielding a positive effect on the colour and fragrance of flowers. Potassium also makes plants more resistant to disease.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering information\u003c\/td\u003e\n\u003ctd\u003eAll include capillary rubber tube with rubber cap and finger clamp, cleaning solution starter kit (120ml), 30ml syringe and instruction.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHI-83900-30\u003c\/td\u003e\n\u003ctd\u003e30cm sampler tube ending with porous ceramic tip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHI-83900-60\u003c\/td\u003e\n\u003ctd\u003e60cm sampler tube ending with porous ceramic tip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHI-83900-90\u003c\/td\u003e\n\u003ctd\u003e90cm sampler tube ending with porous ceramic tip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccessories (buy separately)\u003c\/td\u003e\n\u003ctd\u003eHI-83900-25 Cleaning solution kit, 500ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640090861941,"sku":"HI-83900-30","price":80.27,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/hi-83900-30-suction-lysimeter-30cm_efc0d759-f300-4442-a96e-75aecc961c59.jpg?v=1791581058","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-83900-30-suction-lysimeter-for-root-level-soil-monitoring-30cm","provider":"Test All Water","version":"1.0","type":"link"}
