Description
A soil amendment describes the placement of organic or inorganic materials into the soil in order to promote plant growth. This can happen through several different mechanisms, mainly:
Changing the soil structure
Changing the ability for the soil to retain moisture
Changing the nutrient availability
Changing the pH
Under this definition, fertilizers ARE a type of soil amendment. For information on how soil amendments interact with soil and crops you can read this.
Many types of certifications, including Organic require recording all inputs (see Certifications, certifiers, and LiteFarm for more information) so it’s essential that users can record their use of soil amendments in LiteFarm.
Creation attributes
Attribute | Data type | Required? | Example data | Notes |
|---|---|---|---|---|
Purpose | Enum: {“Change soil structure”, “Change soil moisture retention”, “Change nutrient availability”, “Change pH”, “Other”} | No | “Change soil structure; Change pH, Other” | Must be multi-selectable |
Other | Text | Only if “Other” selected in Purpose | ||
Product | Text | Yes | Cow manure | This will be persisted and retrieved from an inputs table (see Inputs for more details). |
Amount | Decimal (w/ unit) | Yes | 3 kilograms | 0 - 9999. Ideally allows the user to choose either mass or volume Unit displays. |
Supplier | Organic | West Coast seeds | Upon saving a fertilizing task, the fertilizer, supplier, and permitted substances should be written to a table per Inputs. These values can be pre-populated in the future from that table. | |
Listed in permitted substances list? | Enum: {“Yes”, “No”, “Not sure”} | Organic AND farm in Canada | Yes | Upon saving a fertilizing task, the fertilizer, supplier, and permitted substances should be written to a table per Inputs. These values can be pre-populated in the future from that table. |
