Welcome to Sustainable-Ag Solutions, where your agricultural and environmental testing needs are met with the highest standards of excellence.  Find out what we offer growers of all sizes, homeowners, municipalities, horticultural industry, golf course professionals and sports turf.

Soil and tissue testing should never be looked at as extra expense but as a necessary cost saving investment.  Agricultural testing has become the grower’s best tool for saving money by reducing leaching and the avoiding the high cost of unnecessary chemicals.  Testing not only tells what nutrients are needed to produce a good crop but it also tells the condition of the soil and the health of the biological life.  By proper soil testing and interpretation, one can can tell if the microbial life is alive and well.  Testing can pinpoint the correct amount of nutrients your soil is able to hold without being leached to the ground water.  With the use of precision testing, growers have a better idea of the shelf life of their crops and what they need to do to have optimum production.

Sustainable-Ag Solutions believes in working to assist nature by using science to ensure that amendments are added to the soil only when they are needed to produce the best crops possible. Over-application of fertilizers is wasteful and harmful to the environment.  By combining natural processes with scientific methods, we assure that nature will be preserved while producing cost effective, nutrionally healthy crops. 

Sustainable-Ag Solutions believes testing is critical to the complete system of farming.  Our roots are in a set of values that reflects an awareness of both ecological and social realities.  It involves design and management procedures that work with natural processes to conserve all resources and minimize waste and environmental damage, while maintaining or improving farm profitability.  Working with natural soil processes is of particular importance. Sustainable agriculture systems are designed to take maximum advantage of existing soil nutrient and water cycles, energy flows, beneficial soil organisms and natural pest controls.  By capitalizing on existing cycles and flows, environmental damage can be avoided or minimized.  Such systems also aim to produce food that is nutritious, and uncontaminated with products that might harm human health.  Testing is important to understand what the soil can hold and to make sure that only fertilizers that are required are being used.  Excessive use of fertilizers is costly and unproductive to healthy live soils.  A healthy soil is one that has diverse, thriving microbial life forms. 

Soil pH

Soil pH is misunderstood and is often used in the wrong way.  Soil pH is a measurement of the alkalinity or acidity of soil and quantifies the hydrogen-ion concentration in the soil.  It should never be used to decide any corrective treatments.  If pH is out of the desired range for your crop, you should have a complete soil sample performed to make the necessary corrective treatments. Treating soil based only on pH can be costly and can result in crop damage. Even if soil is in the desired pH range, the levels of calcium, magnesium, potassium, sodium, etc. that are responsible for the pH may not be at appropriate individual levels.  Soil pH influences the solubility of nutrients.  It also affects the activity of micro-organisms responsible for breaking down organic matter and most chemical transformations in the soil.  Soil pH thus affects the availability of several plant nutrients.  Below is a chart of nutrient availability at various pH ranges.
