10 Nov pH and EC measurement of floricultural crops using the PourThru extraction method
पोर थ्रू निष्कर्षण विधि का उपयोग कर फूलों की फसलों की पीएच और ईसी की माप Providing a proper nutritional program is essential for growing top quality plants. Sampling the root substrate for pH and electrical conductivity (EC) with the PourThru extraction method is a quick and simple. The pour-through method has been shown to be as satisfactory as other more expensive and time consuming methods of measuring EC. Unlike sampling methods that require removal of medium from containers, the pour-through method does not disturb plant roots. The values provide clues about a crop’s performance before deficiency or toxicity symptoms appear. As nurseries implement more environmentally and economically sound growing regimes, the pour-through method should become more widely used by foliage growers for self-determination of EC levels periodically during the crop production cycle. Since many foliage plants can be grown satisfactorily with a wide range of fertilizer rates. The best fertilization rate, from an environmental and economic standpoint, cannot always be determined by visual inspection. Even though excess fertilizer may not harm some plants, excess nitrogen (N) and phosphorous (P) elements can be lost through leaching and eventually contaminate groundwater. Growing regimes designed to have minimum detrimental impact on the natural environment should include only enough fertilizer for good plant growth, combined with irrigation practices that...
