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.

Nutrient
Symbol
Units Used
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(salt)
dS/m
Levels <0.2 are="" generally="" considered="" negligible.="" levels="">0.8 can be said to be accumulating salt, and should be investigated further.</0.2>
pH
(CaCl2)
>5.0
Economic responses to applying lime to increase pH above 5.0 are doubtful. If subsoil pH is low, it may be necessary to increase topsoil pH >5.5 (CaCl2)
Aluminium
(CaCl2)
5.0

As pH declines (becomes more acidic) Aluminium levels can increase in some soil types. High Aluminium levels will affect root growth reducing their ability to explore large volumes of soil and therefore their access to nutrients and soil moisture. (Read the article on soil pH here)

PBI

PBI is a function of soil type. Generally as a soil contains more iron, clay and organic matter, the higher the PBI. (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.
