Analysis Laboratory

Soil Analysis
Farmers strive to grow healthy plants that produce an economic yield while minimizing environmental impact. An important part of farming is providing plants with proper amounts of lime and essential nutrients. Soil testing can be used to indicate if additional nutrients are needed to achieve optimal yield. Applying the correct amount of nutrient helps achieve desirable yields and quality, while protecting the environment from excess nutrients.

Commercial Vegetables

Successful vegetable growers use soil testing as a guide to fertilizer management. Soil testing helps growers to make informed decisions about fertilizer use and helps protect the environment from pollution by excess fertilizer nutrients.

Ornamentals
A productive soil is essential for healthy, vigorous growth of ornamental plants in the landscape. It assures rapid plant establishment by providing a favorable environment for the developing root system. Information from a soil test will aid in selecting a proper liming and fertilization program to correct problems associated with poor plant growth, such as lack or excess of certain plant nutrients and the level of soil acidity or alkalinity.

Environmental analysis
Environmental AnalysisEnvironmental analysis helps growers make responsible decisions about the use of farm, municipal and industrial wastes and by-products, as fertilizer materials or topsoil for crop production or landscaping.

Field Crops and Forages
Field Crops Knowing and maintaining correct soil pH and nutrient concentrations before seed planting and after establishment is important for obtaining optimum economic forage and grain yields of high quality.
Fruit
FruitAll fruiting plants require fertile soil with optimum pH and balanced nutrients. The lime and fertilizer rates recommended on your CNAL soil test report serve this purpose. Precise fertility management for fruit crops requires plant tissue analyses as well as soil tests.
Plant Tissue Analysis
Plant Tissue AnalysisPlant tissue analysis can indicate whether plants contain the concentrations of essential nutrients necessary for optimum growth. Results help growers monitor nutrient uptake, correct deficiencies before they reach a critical stage, and for some crops, time harvest appropriately.

Optical nitrate analysers

Optical nitrate analysers use the property of dissolved nitrate that it absorbs ultraviolet light. The instrument consists of a light source (deuterium lamp of flash lamp), collimating optics, a light path through the sample water and a spectrometer with photodetector. The resulting absorption spectra have to be analysed (either by an on-board computer or after data recovery) as other constituents in the seawater also absorb ultraviolet light. (For details see Johnson & Colleti (2002[1]))
Optical nitrate analysers do not require any chemical reagents and have a very fast response (on the order of 1 s) and therefore are also suitable for measurements during profiling work, on towed vehicles and AUV's. The detection limits depend on the length of the optical absorption path, generally these instruments are not well suited for low nitrate concentrations (< 1 umol).
The deployment time of the optical instruments is limited by available electrical energy (batteries) and biofouling (though for some instruments anti-biofouling measures can be added).

Wet chemical analysers

A variety of wet chemical nutrient analysers exist on the market. These analysers draw in sample water and mix it with a reagent (or reagents). The resulting solution develops a characteristic property (e.g. colour complex or fluorescence) depending on the concentration of the target analyte, that is then measured in an absorption cell (colour complex) or by a light source and photodetector (fluorescence). In some cases heating of the solution is required to speed up development.
Depending on the chemical protocols followed (i.e. if heating and/or preconcentration steps are needed), the time response (time between independent measurements) is on the order of a few seconds to minutes.
Parameters limiting the deployment time of wet-chemical analysers are reagent consumption, reagent degradation time, available electrical energy (batteries) and biofouling.
A distinct advantage of wet-chemical analysers is the capability of conducting in situ calibrations by piping a blank or standard solution of known concentration into the analyser instead of the sample. Any instrument drift can be detected and the measurements corrected for the drift.
Nutrients that can be measured in situ include dissolved nitrate, nitrite, ammonia, phosphate and silicate (see "external links" to companies below for details).
