Soil Testing and Plant Tissue Testing
The function of plant nutrients in crop production is well proven. There are 16 essential plant nutrients (macro and micro-nutrients). These nutrient elements have to be available to the crops in quantities as required for a yield target. Any limiting or lacking nutrient (or nutrients) will restrict crop growth.
Integrated nutrient management (INM) is a well-accepted approach for the sustainable management of soil productivity and increased crop production. To implement this approach successfully, Green Terra Alliance (GTA) have established well-equipped advanced analytical laboratory facilities for chemical analysis of soils and plants.
Accurate and timely analysis helps in determining the requirements of plant nutrients, to serve the Canadian grower more rapidly and more effectively. GTA’s laboratory has multi-nutrient analysis capabilities and is equipped with many top-notch instruments including ICP-OES (Inductively Coupled Plasma – Optical Emission Spectrometry) and CHNSO Analyzer.
