Chelates - structures, which serve to make many nutrients, especially micronutrients accessible to factories. In absence chelates in the nutritious decision factories would be deprived some key micronutrients which can lead to deficiencies, ingibirovannomu to growth and several other undesirable conditions. Manufacturers should therefore, guarantee, that these structures are present at nutrients which they use in kultivirovanii gidroponiki.
Kleshnevidnoe the word is received from the Greek word "chele", that capable enough association, because helirovanie - process a little as shvatyvanie and carrying out something with a claw means "claw". Therefore it would be interesting to see, how chelates facilitate absorbtion nutrients which differently would be inaccessible on factories. It is a lot of trace elements bear a positive charge as ions in the decision while or opening on roots and leaves of factories negatively charge a time. The element therefore is incapable to enter into factory because of fixing of positive and negative charges. However, with addition kleshnevidnogo, elements, such as iron are concluded in a capsule and changes of a positive charge in pure negative or neutral charge which allows an element to pass through a time in factory.
Synthetic Agents Chelating
The majority of chemical fertilizers includes one or more chelating substances, and higher qualitative fertilizers include a little from these agents. chelating the agent in fertilizer is identified on a label about an element of a trace, to which it serves to make accessible on factories. If the label on a package has letters EDTA about some element of a trace, fertilizer is contained Ethylenediaminetetraacetate usually used chelating by the agent. Higher qualitative grades of fertilizers also contain DTPA or Diethylenetriaminepentaacetate. Fertilizers which include ethylenediaminedihydroxy-phenylaceticacid, designated as "EDDHA" about iron on a label, are first-rate quality fertilizers.
At Chelates there are some points of the appendix with which they "grasp" a trace element. At EDTA there are four incorporating points to elements it chelates while DTPA has five, but higher number of points of communication can be advantage not always. In some cases four points of communication can hold an element too strongly while in a various situation they, probably, do not consider its strained enough.
When they demand chelated an element, factories delete an element, for example iron, from kleshnevidnogo, and it is absorbed in factory. However, being alien to factory, kleshnevidnoe directly it is not absorbed and let out back in the decision.
Efficiency chelating the agent depends, also depends pH the decision factor. EDTA is better approaches little bit more low than neutral levels pH the factor while DTPA is the most effective for high values pH the factor. DTPA is more expensive than EDTA and less razreshimym and it is found in higher qualitative fertilizers.
Most effective of synthetic chelating agents - ethylenediaminedihydroxy-phenylaceticacid (EDDHA). It is found only in the selected formulations of fertilisation because of it concerning high cost. It has been shown, that factories act better, even under adverse conditions, when a primary source of iron - chelated EDDHA. In experiments on aeroponically the grown up chrysanthemums a part of factories have been imparted (infected) with illness of a root (pythium). Only four percent of factories which have been supplied EDDHA, developed hloroz (yellowing leaves) while 35 % of the factories supplied DTPA, became suffering hlorozom. From supplied HEDTA 18 % became suffering hlorozom. In addition, it has been found, that EDDHA delivered the factories absorbed twice quantity of zinc than factories, supplied HEDTA and DTPA.
Biological Agents Chelating
Except synthetic chelating agents, there are structures which occur naturally as fulvic acid which agents function as "natural" chelating. The factories growing naturally, depend from fulvic acids and others chelating agents who as find in the nature, have allowed absorption of elements of a trace. Acid Fulvic follows from decomposition of an organic question in humus. On humus microbes operate to make guminovye acids. Guminovye acids are processed further by microorganisms in fulvic acids. As a little synthetic chelating agents, acid Fulvic forms bonds with four points with elements it chelates, but unlike synthetic agents it can be absorbed in factory. It adds to mobility of nutrients within factory. Nutrients chelated fulvic acid can move more freely which prevents number conditions as the limited deficiency of calcium which happen because of low mobility of nutrients.
.
Acids Fulvic can be the most effective when growing environment in a root zone (rhizosphere) above or is more low optimum. Unlike synthetic chelating agents fulvic acid keeps its efficiency under conditions as high or low pH the factor. Under such adverse factories of conditions supplied fulvic with acid as found, were remarkably free from pressure signs, deficiency etc. than the factories supplied synthetic chelating with agents. Acid Fulvic also makes everywhere round improvement transportability various nutrients in a factory fabric. It is not limited by minerals of fertilizer but also and helps to improve transport of other liquids of factory.
Amino acids form other category biological chelating agents. Amino acids can function well as chelating agents, owe their positive and negative charges which can operate as the North Pole and the South Pole of a magnet. As chelating amino acids of agents form five bonds of point with a mineral element.
The conclusion
As chelating agents allow absorption of set of nutrients, vital for healthy growth of factory, manufacturers should search for nutrients which offer a range of structures chelating. It guarantees nutritious suitability on a wide range of conditions, including those above or more low the optimum. |
