Plants need the right kind of nourishment if they are to produce good yields of high quality. This also helps them build resistance to diseases and plagues. This is why fertiliser research is important for improving the health of the plant and the soil. HLB does not only focus on the main nutritional elements such as nitrogen, phosphate and potassium, we also examine the potential of meso-nutrients and micro-nutrients such as sulphur, magnesium, manganese and boron.
