SWFC is excited to offer a new Plant Sap Analysis service to our customers!
Crop nutrition is traditionally driven by soil nutrient analysis. This works well to establish the range of nutrients available to the plant. But are the plants able to access and take up these nutrients?
A great snapshot of plant nutrients
Plant sap analysis can give a great snapshot of how nutrients are moving through the plant in real-time and identify any potential deficiencies before they even occur. Sap analysis measures the nutrients present in the cell cytoplasm and the plant’s vascular system, showing how the nutrients are moving through the plant as it grows.
Uptake of nutrients can be affected by a multitude of different factors – from fertiliser type to EC or soil type to climate. While leaf tissue analysis can offer a means of diagnosis of nutrient deficiency, sap analysis can highlight any restrictions on the movement of key nutrients before they show as reduced crop health, disease or reduced yield.
As it depends on the plants’ vascular system, samples should be taken at the same time each day, preferably in the morning. This information can then directly influence the choice of fertiliser or foliar feed, for example, or provide valuable information on how forage plants take up nutrients for animal feed. For example, taking samples of ryegrass, chicory, cocksfoot, red clover, birdsfoot trefoil and plantain for sap analysis from an existing pasture could inform species choices when establishing future herbal leys. Animal health from the ground up!
Farmers Weekly recently covered the application of sap analysis in an arable context for disease control. Click here to read the article.
