inSITE - Soil and Plant Testing Service
inSITE is our industry leading soil and plant analysis program delivered by our team of Experienced Area Managers. With inSITE, customers receive a full breakdown of test results for individual paddocks, alongside recommendation reports prepared by their Area Manager. Our recommendation reports outline specific product selection advice to deliver the nutrients required to achieve target yields and are based on our Field Research program and our Area Manager experience of local conditions.

Customers can access their inSITE data through our SummitConnect online customer portal. This portal also gives customers access to trend maps, which allow farmers to visualise how soil nutrients are tracking across different depths and in different paddocks.
Aside from Soil Analysis and Plant Analysis, other services we offer:
- Grain nutrient analysis
- Water quality analysis
- Lime effective neutralising value, gypsum quality analysis and clay assessment
- Pasture feed quality analysis

Adequate Range Expected
Comments
Phosphorus
P
ppm (mg/kg)
15 - 45
Dependent on crop/pasture type and soil type.
Potassium
K
ppm (mg/kg)
40 - 120
Lupins and Canola are less sensitive to K deficiency. Clover and Medic require higher soil levels.
Sulphur
S
ppm (mg/kg)
5 - 15
Dependent on soil type.
Nitrate
NO3
ppm (mg/kg)
up to 30
Very mobile in the soil. May be lost to leaching.
Ammonium
NH4
ppm (mg/kg)
up to 20
Stable in the soil as it is a cation, but converts to Nitrate readily.
Copper
Cu
ppm (mg/kg)
> 0.3
Soil tests for Copper are a guide only.
Zinc
Zn
ppm (mg/kg)
0.12-0.5
Dependent on soil pH. The more alkaline the soil (higher pH) the higher the soil Zinc level needs to be.
Organic Carbon
O.C.
%
1.0 - 3.0
Dependent on soil type and rainfall.
Electrical Conductivity
EC (1:5)
dS/m
< 0.25
A measure of 'salinity'. Highly dependent on soil type with heavier soils having some buffering capability, but generally EC (1:5) values <0.2 are non-saline and >0.7 is of concern and possibly accumulating salt.
A variable conversion factor can be applied so values will fit one scale across all soil types. This is called 'estimated EC' or ECe. In this case ECe threshold of >8 represents highly saline soil.

pH
(CaCl2)
>5.0
Aluminium
Al
ppm (mg/kg)
<5.0
As pH declines (becomes more acidic) aluminium can increase in soil solution. Aluminium is toxic to roots. When roots don't grow, plants cannot explore the soil to access nutrients and soil moisture. Levels above 5 mg/kg strongly impact wheat. Other crops such as barley are more sensitive (Read the article on soil pH here)
PBI
PBI (Phosphorus Buffering Index) is a function of soil type. Generally where soil particles contain more iron, aluminium and calcium such as forest gravels, plus some soils with considerable clay and organic matter, the PBI will be higher and decrease plant-available P (See article)

Soil Analysis
Soil analysis is an essential part of developing a comprehensive fertilizer strategy for the coming season. This service involves gathering critical information on nutrient levels and other key soil traits.
Plant Analysis
Our comprehensive plant analysis service measures the amount of nutrients contained in the plant at the time of sampling and is the best indicator of trace elements currently available.
