Agriculture Manure Nutrient Content

Account declared independent dry-basis manure nutrient components from wet mass and model first-year availability; elemental/oxide bases must be consistent and release fractions are not nutrient sufficiency recommendations.

Description

Manure nutrient inventories depend on dry matter and the assay's nutrient basis.

Manure nutrient inventories depend on dry matter and the assay's nutrient basis. A supplied availability fraction distinguishes total nutrient mass from expected first-year availability.^[1]

When to use Agriculture Manure Nutrient Content

Use this tool to account declared independent dry-basis manure nutrient components from wet mass and model first-year availability; elemental/oxide bases must be consistent and release fractions are not nutrient sufficiency recommendations.

Prepare the field, crop, soil or material measurements for the intended period. Confirm units, dry/wet bases and supplied parameters; keep paired observations aligned.

How to use Agriculture Manure Nutrient Content and understand its results

Prepare the field, crop, soil or material measurements for the intended period. Confirm units, dry/wet bases and supplied parameters; keep paired observations aligned.
Enter manureWetMassTonnes, manureDryMatterFraction, dryBasisNutrientFractions, firstYearAvailableNutrientFractions using the field table and calculation rules, then run the tool.
Read totalDeclaredNutrientMassesKg, firstYearModelAvailableNutrientMassesKg. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
manureWetMassTonnes	Manure wet mass tonnes	number	Required
manureDryMatterFraction	Manure dry matter fraction	number	Required
dryBasisNutrientFractions	Dry basis nutrient fractions	list of number	Required
firstYearAvailableNutrientFractions	First year available nutrient fractions	list of number	Required

Enter nonnegative wet manure tonnes, dry-matter fraction in [0,1] and aligned nutrient and first-year availability fractions in [0,1]. Independent dry nutrient fractions cannot sum above one. Return total component kg and each total times its availability fraction.

Paired lists must be nonempty and have equal lengths.

totalNutrientKg_i = wetTonnes × 1000 × dryMatterFraction × dryNutrientFraction_i

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
totalDeclaredNutrientMassesKg	Total declared nutrient masses kg	list of number
firstYearModelAvailableNutrientMassesKg	First year model available nutrient masses kg	list of number

Limitations and assumptions

Assays must use consistent independent elemental bases; oxide percentages require separate handling. Availability is supplied calibration, not nutrient sufficiency or an application recommendation.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Agriculture Fertilizer Requirement Nitrogen: Balance caller crop N uptake/available soil/other credits with explicit recovery/product fractions; a simple accounting scenario, not agronomic sufficiency, environmental permission or application recommendation. For a complementary task, use Agriculture Fertilizer Requirement Phosphorus: Account harvest P removal plus caller soil-build budget and credits, explicitly separating elemental P, P2O5 and product mass; distinct from N recovery/uptake balance, without soil-test recommendations.
