Soil sampling and analysis is not just for the broad acre farmer it is one of the most productive tools available, for anyone who grows a crop, a tree or a bunch of flowers.
Whether fertilising through the irrigation water or by conventional broadcast, some important aspects to take into consideration are the different soil types and nutrient levels that are present. Nutrient levels that may not need adjusting and others that need tweaking with a few teaspoons and others that require truck loads.
Money could be saved by targeting the inputs and adjusting through simple soil tests and their analysis. One of the best articles on soils we share here https://robinsonloveplants.com/soil-building-soil-amendments-rain-barrels/ to the point without too much detailed science!
There are many organisations that carry out soil analysis, one of the most popular is NTS http://www.nutri-tech.com.au/soil-and-plant-therapy, followed by APAL http://www.apal.com.au/ .
In the article below four (4) very relevant case studies are presented, we acknowledge the Government of Western Australia for the article.
