Leaf SAP Analysis
Sherriff Amenity are delighted to now be offering a Leaf SAP Analysis service.
Plant nutrient tests and soil analysis are used to diagnose nutrient requirements and provide information for adjusting fertiliser programmes. SAP analysis measures the nutrient concentration in the sap and can be used to forecast nutrient deficiencies. A SAP analysis can tell you the current uptake of nutrients and nutrient deficiencies and / or excesses long before visible symptoms first appear in the grass. It serves to highlight the nutrients which the grass is able to use for growth at that moment. It can also indicate nutrient imbalances in the soil and provide information for selecting fertiliser.
A SAP analysis will quickly show highs and lows of nitrogen inputs. This nutrient is a major limiting factor to healthy grass growth. It is an essential component of amino acids and proteins that are the building blocks of grass growth. It is also a vital component of chlorophyll, which is required for carbohydrate formation (photosynthesis)and this is essential for turning the grass green. Under poor growing conditions, such a slow soil temperatures, nitrogen mineralisation and availability can be a major limiting factor to grass growth. This can be readily identified in the SAP analysis.
