are being widely used in the field of agriculture than in any other
field of science and their application is leading us to the solution
of many agriculture problems in a shorter time and more precisely.
Thus, radioisotopes have become a very important aid to scientists
dealing with the solution of agricultural problems. In addition to
this, radioactive tracers and radiation sources have become
indispensable to all the intricate agricultural research problems.
Radioisotopes and radiations give us the chance to clear the events
that once were mysterious in the nutrition and growth of plants and
evolution of new crop varieties. They help us to clear the casual
factors, which produce ill-effects to the plants in different ways.
In agriculture, radioisotopes
are used in the nutritional studies of major and minor elements,
milk production, mechanism of photosynthesis studies. Plant
protection, plant pathology, action of insecticides, uptake of
fertilizers, ions mobility in soil, and plants and food
preservation. In order to determine the correct nutrition for a
plant we need to know the exact soil plant relationship and the
factors involved therein.
