Dry Matter

Dry matter refers to the portion of plant material that remains after all the moisture or water content has been removed. Dry matter includes all the solid components of the plant, such as fibers, carbohydrates, proteins, fats, minerals, and other nutrients. Water, on the other hand, is the liquid component that makes up the rest of the plant's weight.

The dry matter content is a crucial concept in agriculture and animal husbandry because the nutritional value of feed, including forage grass, is determined based on its dry matter content. In practical terms, knowing the dry matter content of forage grass allows farmers to accurately formulate animal diets, estimate nutrient intake, and manage livestock nutrition more effectively. It also aids in comparing the nutritional value of different forage sources and adjusting feeding programs to meet the specific dietary requirements of different livestock species and production stages.

Usage

The processDryMatter() mutation and retrieveDryMatter() query are used to generate and retrieve dry matter analyses. They each require three arguments:

  • polygonId
  • startDate
  • endDate


mutation {
  processDryMatter(
    polygonId: "[YOUR POLYGON ID GOES HERE]"
    startDate: "2023-01-01"
    endDate:   "2023-07-31"
  )
  {
    IsSuccess
    Message
    Status
    Result {
      requestId
    }
  }
}



query {
  retrieveDryMatter(
    polygonId: "[YOUR POLYGON ID GOES HERE]"
    startDate: "2023-01-01"
    endDate:   "2023-07-31"
  )
  {
    IsSuccess
    Message
    Status
    Result {
      tif
      png
      json
      colorlegend
    }
  }
}
