Chemical indicators can give you information about the equilibrium between soil solution (soil water and nutrients) and exchange sites (clay particles, organic matter); plant health; the nutritional requirements of plant and soil animal communities; and levels of soil contaminants and their availability for uptake by animals and plants. Indicators include measures of:
Ion-selective electrodes, (6 perimeter including Potassium and Nitrates )
Research Grade Meters
Chemical analyzes (12 Nutrients)
Titration based testing (several key nutrients)
Physical indicators provide information about soil hydrologic characteristics, such as water entry and retention, that influences availability to plants. Some indicators are related to nutrient availability by their influence on rooting volume and aeration status. Other measures tell us about erosional status. Indicators include measures of:
Biological indicators can tell us about the organisms that form the soil food web that is responsible for decomposition of organic matter and nutrient cycling. Information about the numbers of organisms, both individuals and species, that perform similar jobs or niches, can indicate a soil's ability to function or bounce back after disturbance (resistance and resilience). Indicators include measures of:
All this information is placed into software for our grower’s database or their land and soil. Having done soil testing and plant testing for over 25 years, and working on thousands of fields and common sense results have created Parkland Agrophysics inc.
