Sampling for Analysis
Analysing plant tissue, soil, growing media, water and hydroponic solutions produces numerous benefits to the grower: a proven process to achieve much healthier and stronger crop growth with higher yields and added disease resistance; production becomes more efficient as growth improves due to less plant stress and less disease control measures; and minimised crop loss. The key to effective analysis is timing and knowing how and what to sample in order to optimise the amount of fertiliser/ameliorant required for a specific growth stage. A prompt return of test results will allow the corrective measures to be applied on time instead of weeks later when less than ideal growth has occurred or problems have compounded.
