Field of Study Project TitleThe effect of soil salinity on plant growth is part of botany, the study of plants.Botany: The study and science of plants in a particular habitat and region, is the branch of biology that deals with plant life. Soil salinity: should we worry? Introduction Soil salinity is said to be "bad" for plant growth, but is it really true? Is it just a big misunderstanding? Is it really the 'fault' of the salts? Are there no solutions to solve this problem? These are some of the questions many people should ask themselves before deciding whether salt is a friend or foe. Instead of just following what others say, people should know exactly how soil salinity affects crops and why this happens. To know our enemy, in this case "salt", it is necessary to do experiments, collect and process the results and there must be an explanation to understand the different outcomes and results. We decided to find out all about soil salinity and how it affects plant growth because plants are an important part of our lives, we live and breathe by them and we want them to flourish. First, these are some information and questions that will make it easier to understand the whole concept. Lettuce will be used for the experiment because it is one of the most widely grown vegetables in South Africa by farmers. What is soil salinity? Salinity is simply the amount of salts in the soil that is estimated by measuring the electrical conductivity of a removed soil solution. An electrical device can easily measure the amount of salt contained in the soil. In millimhos/cm or micromhos/cm, a salt concentration of one gram per liter is approximately 1.5 millimhos/cm). The salinity of the soil ef...... half of the paper...... is damaged cannot be easily recovered due to the now rock hard surface which does not easily absorb rain and water. Saline soil is also vulnerable to erosion as the vegetation that held it together dies. Eroded soil can also "pollute" the water. By finding out the maximum amount of salt that a plant (lettuce) can tolerate, we will be able to understand whether the soil is usable or not and what the result of the plant will be. , if the plant is planted in soil with a certain amount of salt. WHAT CAN BE DONE TO AVOID FURTHER DAMAGE? CORRECT WATERING CAN AVOID THE ACCUMULATION OF SALT BECAUSE THE WATER CAN DRAIN THE SALTS AND DIFFUSE THEM SO THAT THE SALTS ARE T CONCENTRATED IN A SINGLE AREA!!! MORE ORGANIC FERTILIZERS MUST BE USED, NOT POTASSIUM BASED FERTILIZERS. SALT TOLERANT PLANTS CAN BE PLANTED TO AVOID FURTHER DAMAGE AND RECOVER THE SOIL.
