4 Introduction Netafim s CMT systems: delivers the real time data needed for precision irrigation decisions

5 General Costing Greenhouse cost can vary between R200 to R400 per m² Item % of Total Greenhouse Structure and Plastic 33% Erection of above (installation of structure) 7% Pad and Fan (including electrical cable and switchgear) 16% Screens 18% Heating 14% Irrigation Head Control (pump house and NMC control) 5% Infield Irrigation equipment 5% Climate control (NMC products) 2%

6 Costing - Statement Irrigation equipment and control (including climate) are the smallest portion of the cost, but this give the grower a tool to manipulate the crop for optimum yield. Management of the above must be simple and user friendly. Question: Why do we neglect this process? Why do we compromise on design and standards?

7 Why Dosing? Visible Deficiency Symptoms Visible Toxicity Symptoms Optimal Level Plant Gro owth, Yield Critical Deficiency Level Critical Toxicity Level Content of Mineral Nutrients in Dry Plant Tissue Nutrient / Growth Ratio
