$117
Excludes GST
Our ultimate test for arable and horticulture crops. It covers all the essentials from our Pasture Soil Test, plus nitrogen. Perfect for managing nitrogen, switching from pasture to crops, or planning crop rotations.
When to test: Autumn - Spring. Every two or three years. Generally 7.5cm depth.
Measures: pH, Olsen P, Ca, Mg, K, Na, Bulk Density, CEC, Base Saturation + SO4-S + Organic S + Anaerobic Mineralisable Nitrogen (AMN)
For each Cropping Soil Test you add to your cart, you will receive 1 x ARL sample bag in your test kit, which is posted out to you containing all the information you need to get started with your DIY soil testing.
Purchase one Test for each paddock/area you want test.
WHAT'LL THIS TEST MEASURE?
| pH | Measures the acidity or alkalinity of the soil which affects the availability of nutrients to plants. |
| Phosphorous (Olsen P) | Assesses the availability of Phosphorous to plants, important for energy transfer in plants supporting plant growth and health. |
| Cations (Calcium, Potassium, Magnesium and Sodium) | Measures the extractable amount of cations, key nutrients essential for plant growth. |
| Cation Exchange Capacity (CEC) | The higher the CEC the greater the capacity of soil to store and retain cations (Ca, Mg, K, Na) |
| Base Saturation | Provides a percentage saturation of the CEC for each of the cations and can be used to better understand and plan your fertiliser needs |
| Volume weight | The density of a known volume of air-dried and ground soil - gives an indication of the soil’s physical character (e.g. sandy soils vs clay vs pumice vs peat, etc) |
| Sulphate Sulphur (SO4) | Provides the extractable amount of Sulphate Sulphur - a building block for plant protein |
| Extractable organic Sulphur | Provides the extractable sulphur content in the organic matter which is an indicator of sulphur reserves in the soil |
| Anaerobic Mineralisable Nitrogen (AMN) | Measures the potentially available nitrogen in the soil that is tied up with the organic matter. |
