Nitrogen And Phosphorus Compound Fertilisers, M G. Mason, J. W. Bowden

Journal of the Department of Agriculture, Western Australia, Series 4

Nitrogen and phosphorus are two vitally important elements for plant growth which are deficient in most soils throughout Western Australia's agricultural areas.

Both nitrogen and phosphorus can also be applied in appropriate compound fertilisers which can be drilled with the seed, thus making their handling much easier. However, excessively high rates can depress plant emergence and may lower crop yields.
