| Sensitivity review: |
Completed. Public-source evidence only. |
| Purpose: |
This page records secondary evidence on whether industrial hemp is agronomically and geographically plausible in the Granite Borders region. It does not conclude that hemp is suitable for the region. It identifies the conditions and pathway-specific checks needed before suitability can be assessed. |
Regional Evidence Position
The strongest regional evidence is the AgriFutures Industrial Hemp Variety Trials work at Stanthorpe. It provides direct evidence that hemp can be trialled successfully in the historic Stanthorpe area, including grain and biomass results. The evidence is weaker for current Tenterfield Shire because no Tenterfield hemp trial evidence has yet been located, although BoM climate data show a broadly comparable high-elevation, summer-rainfall environment.
The main suitability issue is not simply "can the crop grow?". It is whether a legal variety, product pathway, water regime, harvest system, storage pathway and buyer/processor route can be matched to a local farm.
AgriFutures Australia's 2023 best management practice manual is now treated as the main Australian national agronomy reference for this screen. It is useful for identifying production prerequisites and operational risks, but it is not local Granite Borders trial evidence and does not prove profitability or environmental benefit. Its guidance must be tested against local soils, water, frost exposure, product pathway and market access. Source: S059.

Agronomic Suitability Screen
| Suitability factor |
Current evidence |
Regional implication |
Confidence |
| Temperature and frost |
BoM stations show cool winters and frequent days at or below 0 C. AgriFutures BMP guidance identifies ideal sowing once soil temperatures are consistently above 10-12 C and frost is not forecast. |
Sowing windows must avoid damaging frost risk and should be checked against variety-specific growth stages and soil temperature, not only calendar date. |
Medium |
| Summer rainfall |
Rainfall is summer-dominant at the reviewed stations. The BMP manual indicates industrial hemp needs reliable crop-season water, especially for establishment, and gives indicative irrigation or rainfall requirements. |
Summer moisture supports plausibility, but crop establishment, first six weeks water demand, soil moisture and irrigation access remain property-specific. Dryland and irrigated scenarios should be separated. |
Medium |
| Direct trial evidence |
Stanthorpe IHVT evidence reports grain and biomass yields under local trial conditions. |
Strong lead for historic Stanthorpe area; not automatically transferable to every soil, enterprise or Tenterfield farm. |
Medium to High |
| Variety choice |
Hemp Farms Australia identifies varieties and sowing windows for dual-purpose, grain and fibre uses; Australian Hemp Council and the AgriFutures BMP manual stress matching variety to market, location, latitude, harvest system and THC compliance requirements. |
Variety selection should follow the intended product pathway and local agronomist advice, not generic hemp claims. Dual-purpose varieties may trade flexibility against yield or quality. |
Medium |
| Water and irrigation |
Trial and industry sources repeatedly identify water-use efficiency and establishment moisture as important. The BMP manual indicates southern growing areas may require frequent irrigation and that high-yielding crops may use substantial seasonal water. |
Dryland versus irrigated budgets should be separated. Water availability, irrigation capacity and drainage may determine realistic yield and crop risk. |
Medium |
| Soil and nutrition |
Stanthorpe trial notes and the BMP manual point to soil, fertility, compaction, drainage, pH, pest and weed management requirements. The manual identifies well-drained uniform or gradational soils with pH around 6-7.5 as preferred and warns against waterlogging and compaction. |
Soil testing, pH, fertility, compaction, drainage and plant available water need property-level assessment before any suitability conclusion. |
Medium |
| Chemical-use pathway |
APVMA sources confirm legal registered and permitted chemical pathways. The BMP manual reinforces the need to check current APVMA options, monitor pests and weeds, and account for application constraints in tall crops. |
Crop protection is possible but not automatically low-input; legal labels, crop height, application access, withholding periods and buyer residue limits must control assumptions. |
Medium |
| Harvest and storage |
The BMP manual identifies grain harvest as challenging and stresses immediate access to drying, cleaning and storage facilities for grain or planting seed. Biomass pathways require cutting, windrowing, retting and baling. |
Regional suitability depends on machinery, contractor availability, drying/cleaning/storage access and weather during harvest or retting. |
Medium |
| Processing geography |
Fibre/hurd supply-chain evidence emphasises local processing because stalk and hurd are bulky and freight-sensitive. |
Regional suitability for fibre/hurd is low until a practical processor route is verified. |
Medium |
| Market geography |
Food processors and seed/genetics actors exist, but no local Granite Borders buyer has been confirmed. |
Suitability for producers depends on accessible offtake, not only agronomy. |

Agronomy Profile From Australian BMP Manual
The following profile translates the AgriFutures BMP manual into decision-useful agronomy checks for Granite Borders. It should be read as national production guidance requiring local validation.
| Topic |
BMP guidance relevant to agronomy profile |
Granite Borders assessment use |
Perspective relevance |
| Variety and product pathway |
Variety choice should match end product, location, latitude, sowing time, THC compliance, crop rotation and harvest system. |
Assess grain, fibre, hurd/biomass and dual-purpose crops separately; do not build one generic hemp profile. |
Producer; Supply Chain |
| Sowing and establishment |
Germination and emergence depend on seed quality, storage, soil temperature, soil moisture and even establishment. Establishment losses can materially affect final plant density. |
Compare sowing windows with Tenterfield, Stanthorpe and Applethorpe frost and soil-temperature conditions; include establishment-risk allowances in budgets. |
Producer |
| Soil and drainage |
Preferred soils are well-drained, uniform or gradational, not sodic, not compacted and commonly around pH 6-7.5. Hemp is sensitive to waterlogging and compaction. |
Screen candidate properties for soil pH, drainage, compaction, duplex constraints, plant available water and erosion risk. |
Producer; Environment |
| Nutrition |
Hemp requires nutrient-rich soils and fertiliser planning; nitrogen timing can affect yield and disease or water-quality risk. |
Build soil-test-led nutrition scenarios rather than assuming low-input production; compare nutrient needs with existing enterprises. |
Producer; Environment |
| Water and irrigation |
Reliable water is important for establishment and yield. The manual gives indicative crop-season water or irrigation needs and notes biomass crops can require more under some conditions. |
Separate dryland, supplementary-irrigation and fully irrigated cases; test against local water entitlement, storage, irrigation capacity and drainage. |
Producer; Environment |
| Pests and diseases |
The manual identifies insect, mite and disease risks and recommends monitoring, integrated pest management and biosecurity vigilance. |
Do not assume hemp is pest-free; include scouting, advice, possible treatment and application-access constraints. |
Producer; Environment |
| Weeds and volunteers |
Weed control before planting is important. Dense crops may suppress weeds, but poor establishment increases weed competition. Volunteers after grain harvest may affect following crops. |
Test fit with existing rotations, knockdown options, pre-emergent pathways and follow-up crop plans. |
Producer; Environment |
| Pesticide application |
Current APVMA options must be checked. Tall crops may require high-clearance or aerial application late in the crop cycle. |
Include practical spray-access constraints, label limits, permit status and buyer residue requirements in any farm scenario. |
Producer; Environment |
| Harvest and post-harvest |
Grain, planting seed, fibre and biomass pathways require different harvest timing, machinery, drying, cleaning, storage, retting and baling arrangements. |
Suitability depends on local contractor availability, machinery compatibility, storage/drying access and weather risk during harvest or retting. |
Producer; Supply Chain |
| Farmgate economics |
Budgets should be conservative and include licensing, seed, fertiliser, labour, machinery, water, pest control, harvest, drying, cleaning, storage and contract terms. |
Use as a cost-category checklist for producer economics; do not infer profitability until buyer prices, processor fees and freight-adjusted returns are verified. |

Specialist opportunity only; requires direct validation. |
| Fibre / bast |
Stanthorpe biomass signal and fibre cultivars support biological plausibility. The BMP manual highlights different biomass harvest, retting and baling needs. |
No verified nearby decortication or fibre processor; bulky freight; harvest and retting weather risk. |
Agronomically possible but commercially high risk. |
| Hurd / hempcrete |
Building-material actors and hurd processors exist nationally. |

Follow-Up Priorities
- Extract the full Stanthorpe final report data, including sowing dates, cultivar performance, water-use efficiency, grain quality and management constraints.
- Seek any Tenterfield, Northern Tablelands, New England, Darling Downs or Granite Belt hemp trial evidence not located in this pass.
- Compare climate stations with candidate farm locations and soil/land capability data.
- Model freight from Tenterfield, Stanthorpe and Applethorpe to verified processors and buyers.
- Validate sowing windows, frost risk, irrigation needs and pest/weed management with agronomists and growers.
- Use the AgriFutures BMP manual as the baseline agronomy checklist when developing producer economics scenarios and interview questions.
