Abstract

                                There are no two opinions that one of the surest methods of increasing the yields of crop plants is to increase the capacity of the soil to supply nutrients to the plant by manuring. It has also been the experience that identical results are not obtained by identical methods practised. At the outset it may be stated that in the paragraphs that follow, no distinction is made between the words 'manures' and 'fertilizers'. Manures in this special sense mean substances belonging to plant residues while fertilizers imply those of mineral origin. It is not proposed to give any detailed recommendations about manuring, but certain basic principles based upon past experience at various Research Stations and the crop in general will be presented.
