Laboratory work on the study of the effect of electric current on cotton. Aim: To inform students on how electric current, which travels through the soil, affects the growth, development, and productivity of a cotton field. Necessary materials: 1) power source; 2) connecting wires; 3) carbon electrodes; 4) copper oxide rectifiers; 5) ruler; 6) clock; 7) thermometer; 8) different types of cotton. Procedure: The goal is to study the effect of this current on the growth and development of cotton when the current passes through the soil. Because soil and cotton contain solutions of various salt and acid ions with certain concentrations. Soil contains calcium carbonate, sodium sulfate, sodium chloride, calcium chloride and other salts of hydrochloric acid. If the soil is artificially electrified or a certain amount of current passes through the soil, the effect of this current on cotton growth and development will be significant. Soil water can be called a soil solution because substances are present in it as a true or colloidal solution. Gases in soil air in the soil solution - CO2, O2, N2, etc., anions - HCO3-, NO3-, NO2-, PO3-, Cl-, SO42-, cations - Ca2+, Mg2+, K+, NH4+, AL3+ trace elements - copper, zinc, lead, nickel, cobalt and other water-soluble organic compounds - carboxylic acids, amino acids, carbohydrates, alcohols and others are dissolved. Soil arrangement assumes a significant part in its life and plant sustenance. The presence or nonappearance of particles of specific substances in the dirt arrangement shifts as per regular circumstances, particularly climatic circumstances. There is a sum accessible in the dirt. At the point when manganese, copper, molybdenum, and in a few explicit circumstances, cobalt, zinc, iodine and other microelements are deficient with regards to, explicit illnesses are seen in crops, which produce low and low quality yields. For this situation, the utilization of fitting micro fertilizers disposes of plant illnesses and works on the yield and nature of plant items. In many plants, how much sugar, starch or protein, nutrients and fats increments affected by micronutrients. The obstruction of plants to dry spell, high and low temperatures expands, their harm brought about by bugs and illnesses diminishes. The lack of certain trace elements in the soil can be determined by the appearance of specific symptoms on the appearance of plants. It is also possible to find out the lack of microelements in plants. In this case, the growth and development of the plant slows down, they produce less. It is necessary to develop new methods of assimilation of microelements. In this case, the simplest method is absorption of microelements by plants as a result of electric current.
