The accumulation of mineral salts in irrigated land is called soil salination. One of the undesired effects of irrigation is soil salination. Irrigation water often contains some salt at varying levels. Salt is nasty to plants and does not make themn grow, so farmers have to deal with salination by flushing the soil with extra water to leach salts out. Proper soil management and monitoring of water table is necessary to reduce impact of salination to soil quality.
Answer:
The correct answer to the question above is "PLATE COUNT TECHNIQUE"
Explanation:
DIRECT MICROSCOPIC OBSERVATION is the method of estimating the number of microorganism using microscope. Samples to be estimated are placed on microscope slides which allow few cells in a small volume to be counted. Then, the value determined is used to estimate the total number of cells mathematically. It is only difficult to aee small cells which may affect precision.
VIABLE COUNT is the estimation of the living cells in a given sample.
PLATE COUNT TECHNIQUE is used to estimate the number of viable cells that are present in a given sample of actively growing or dividing cells based on bacteria cells found on agar plate. A sample to be counted is diluted in a solution that will not kill the microorganisms, this is done to enable accurate counting as only living bacteria will be counted.
