Soil health indicators using microbial composition
An analytics system uses soil health indicators to determine metrics for soil samples. In an embodiment, the analytics system receives metadata describing a soil sample, where the metadata indicates one or more types of crops grown in a geographical location having the soil sample. The analytics system determines nucleic acid sequence reads of the soil sample. The analytics system determines taxonomic information of the nucleic acid sequence reads. The analytics system determines microbial composition of the soil sample using the taxonomic information. The analytics system determines reference metrics of soil samples from geographical locations in which the one or more types of crop were grown. The analytics system determines a metric of the soil sample using the microbial composition and the reference metrics. The analytics system transmits the metric to a client device.
1. A method comprising:
obtaining a soil sample from a geographical location having an attribute based on one or more applied products or been treated with an agricultural technique;
determining, by an analytics system including one or more processors and a memory, a plurality of organisms in the soil sample known to be associated with post-harvest disease pressure;
determining, by the analytics system, a microbial composition of the soil sample using a normalized count of each of the plurality of organisms;
determining, by the analytics system, that a plurality of soil samples from a plurality of geographical locations within a threshold distance of the geographical location have the attribute based on the one or more applied products or been treated with the agricultural technique;
determining, by the analytics system, reference metrics of the plurality of soil samples from the plurality of geographical locations within the threshold distance of the geographical location, wherein the plurality of soil samples from the plurality of geographical locations provide context to the microbial composition of the soil sample, and wherein the reference metrics include a distribution of values of soil health indicators;
determining, by the analytics system, a metric of the soil sample indicative of post-harvest disease pressure by comparing the microbial composition to the reference metrics of the plurality of soil samples from the plurality of geographical locations; and
transmitting, by the analytics system, the metric to a client device for display in context of the reference metrics on a user interface.
2. The method of claim 1 , wherein the plurality of organisms in the soil sample known to be associated with post-harvest disease pressure includes microbes having a genus of Botrytis, Botryotinia, Alternaria, Mucor, Rhizomucor , or Rhizopus.
3. The method of claim 1 , wherein the one or more applied products includes a fumigant.
4. The method of claim 1 , wherein the agricultural technique is no-till farming, use of a cover crop, carbon farming, strip-till, or conservation agriculture.
5. The method of claim 1 , wherein the metric is displayed as a percentile value.
6. The method of claim 1 , wherein the soil health indicator indicates soil mineral or organic element availability, a plant growth promoting factor, an interaction with plant pathogens, or crop performance.
7. The method of claim 1 , further comprising:
determining, based on the metric, a prediction of a physical attributes of a plant grown in soil at the geographical location.
8. A system comprising one or more processors and a memory, the memory storing computer program instructions that when executed by the one or more processors cause the one or more processors to:
determine a plurality of organisms in a soil sample known to be associated with post-harvest disease pressure, wherein the soil sample is obtained from a geographical location having an attribute based on one or more applied products or been treated with an agricultural technique;
determine a microbial composition of the soil sample using a normalized count of each of the plurality of organisms;
determine that a plurality of soil samples from a plurality of geographical locations within a threshold distance of the geographical location have the attribute based on the one or more applied products or been treated with the agricultural technique;
determine reference metrics of the plurality of soil samples from the plurality of geographical locations within the threshold distance of the geographical location, wherein the plurality of soil samples from the plurality of geographical locations provide context to the microbial composition of the soil sample, and wherein the reference metrics include a distribution of values of soil health indicators;
determine a metric of the soil sample indicative of post-harvest disease pressure by comparing the microbial composition to the reference metrics of the plurality of soil samples from the plurality of geographical locations; and
transmit the metric to a client device for display in context of the reference metrics on a user interface.
