This article demonstrates how project managers can achieve greater success if trained in people skills. Project management is an important skill for businesses to have – particularly companies whose business rests on delivering projects. Often project managers are trained in the technical aspects of project management such as setting objectives; critical path analysis; work breakdown structures; resource allocation and risk management. However, the success of a project often rests on the understanding of related people and management issues, rather than technical issues. ITNET, a UK‐based consulting and business process outsourcing company, reveals how adding soft skills training, such as influencing, motivation, and delegation, to technical project management training can positively impact a business.

A Previous investigation by the writer (1) showed that cyanamide readily breaks down, yielding ammonia in normal clay and sandy soils. The evidence, however, threw no light upon the cause or nature of this change. This question was accordingly reserved for a later investigation. The concensus of the available evidence indicated that the production of ammonia from cyanamide in the soil is due to direct bacterial action. This view was held by Immendorff(2) and Kappen(3), who concluded that in poor soils of low bacterial activities cyanamide is not converted into ammonia but is chemically transformed into dicyanodiamide. Löhnis(4) at first accounted in a similar way for the formation of ammonia from cyanamide in the soil. He(5) assumed later, however, that cyanamide is normally decomposed by soil colloids into urea or possibly some other substances, and the latter are then converted into ammonia by the soil organisms. He adduced no direct evidence of the production of urea from cyanamide in the soil.

With I Text-egure)Increased attention has been given in recent years to the study of nutrient-deficiency symptoms in different plants. The published results of this type of work have been derived from examination of the plant grown more often in sand or water culture than in the field. A plant grown in sand culture and in the field may react differently to the same deficiency owing to variation in the cultural conditions, since it is impossible to reproduce in sand the complexity of factors present in soil, the interactions of which may induce not only the incidence but also the nature of deficiency symptoms. The study of plants grown under controlled conditions in sand and water culture may assist the diagnosis of deficiency symptoms under field conditions, but extreme care is necessary in hterprethg the d t s SO obtained in terms of the behaviour of the plants under natural conditiona.The external reactions of a plant to deficiencies or to su$ciencies of plant foods may afford a better understanding of the mutual relationship between soil and plant than even an elaborate soil analysis. Field studies of this type would at least facilitate interpretation of soil analyses and thus contribute to the solution of manurial problems. In this connexion there may be grounds for regret that modem field fertilizer trials, in which the responses can be assessed statistically, have not been more utilized for the study of the incidence of nutrient deficiencies in relation to manurial treatments. The evidence from P~~~O U S studies suggests that the effects of a nutrient deficiency on the plant XMY be intensified by some specific interaction between the deficient element and one or more of the other elements. Similarly, the presence of one or more nutrients in definite excess in the soil XMY interfere with the solubility, absorption or utilization of another element to such a degTee as to induce acute deficiency symptoms on the plant, although there might be an adequate Supply of the second element for normal growth in the absence of the excess of other elements. A comprehensive publication (Hambidge, IWI), illustrated by colour and black and white phta, deals with deficiency symptoms on a wide range of plants. A similarly illustrated publimtion (Es.tein et d. 1937) is devoted exclusively to potash-deficiency symptoms. Potashdeficiency effects, as Uhibited by the potato plant in the field, are well illustrated in both these publiatiom. It has been generally assumed that leaf scorch and other potash-deficiency symptom are P -Y induced by a combination of high nitrogen and low potash in the soil. T h e abnormally green colour of the fohage on the NP plots was attributed mainly to the unbalancing influence of the nitwen. The W W P h Was based on observations of plots in the older type of experiment which did not ~a d y include separate nitrogen and phosphate treatments. Wallace (1925 a, 6) showed that a wide ratio Of nitroscn to potash (nitrogen/potash) was a vitd factor in the incidence of leaf S C O~ on fruit P h a . F-Y (1928)...
