The downside is that it is\u00a0not particularly easy (or in some cases, possible) to test every parameter in harsh environments accurately or without causing damage to the sensors.<\/p>\n<p>With this in mind, I am planning to take a sightly different approach: a sensor for use in the field that measures parameters that\u00a0<em>must\u00a0<\/em>be collected\u00a0<em>in situ <\/em>(such as temperature and moisture), supplemented by benchwork preformed in the evening to collect other relevant soil parameters. The evening benchwork would also have hardware and software components. For example LED\/photometer sensors could be used to measure organic content and other optical sensors could be used to make observations about the color of the soil and its composition.<\/p>\n<p>The next steps for me are:<\/p>\n<ol>\n<li>Learn more about the chemistry of soil fertility and ph and find a way to test them cheaply without using standard kits.<\/li>\n<li>Consider the hardware element. Look for cheap sensors that are compatible with Arduino boards and begin preliminary designs. I will probably build\u00a0the temp\/moisture sensor first since it most closely follows the paradigm of sensors that have already been developed\u00a0as a part of this research.<\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>My current project is to develop a functional and consistent set of sensors and protocols to collect information about important soil parameters such as pH, fertility, conductivity, temperature, organic content, and moisture.
