Multiple methods can be used based on individual budgets including:
Traditional Soil Testing
Test soil content and balance to identify potential restrictions and/or salinity issues.
Soluble Nutrient Testing
Determine how well your soil is functioning, actual nutrient availability via the water stream and the potential for toxicity and/or salinity issues.
Identify nutrient shortfalls or restrictions in actual nutrient uptake.
Determine biological balance and activity of soil and by extension nutrient cycling and thatch degradation.
Determine water quality and your input to help determine water quantity applied. Illustrate what and how much of each constituent is being contributed to your specific growing medium to allow a more pro-active approach to management preventing the reactive roller coaster of highs and lows.
