Soil management and mineral nutrition Herbicide-based soil management may reduce phosphorus uptake into leaves and fruits and increase susceptibility of fruit to low temperature breakdown during storage. Apply phosphorus sprays in Cox and Bramley orchards …
The effect of composted green waste on tree nutrition Nutritional guidelines that combine adequate cropping with good storage potential …
AHDB Horticulture funded Project TF 177 to assess the long-term effects of applied composted green waste mulch on the cropping of Braeburn and Cox apple orchards. Trees growing in a bare herbicide strip in a Braeburn and Cox orchard in Kent were compared …
Nitrogen In Cox orchards apply sufficient nitrogen fertiliser to achieve a maximum nitrogen concentration of 2.6% (dry weight) in leaves and 70 mg 100g-1 (fresh weight) in fruit at harvest. In Bramley orchards apply sufficient nitrogen fertiliser to …
Predicting storage potential of apples using fruit mineral analysis Make an assessment of the storage potential of Cox and Bramley apples from all orchards intended for storage by the use of mineral analysis. Sampling Samples should be taken at random in …
Equipment calibration for post harvest treatment Good practice preparing for post harvest treatment Good practice during post harvest treatment Good practice following post harvest …
The following procedures should be adopted for calibration: Measure volume of tank. For square tanks calculate volume = height x length x width. For round tanks calculate volume = radius x radius x height x 3.142. For measurements in metres multiply …
The following procedures should be adopted for operation: Mark the tank to show the operating level (full). Add clean water until the tank is approximately three-quarters full. Use a clear area to weigh or dispense chemicals. List chemicals and quantities …
Treat fruit for 60 seconds maximum. Fruit should not be treated above 21 o C or below 100C (optimum 16 o C). Top-up using solution diluted to the correct concentration. Change solution every 2 or 3 days or when excessively dirty. DPA manufacturers suggest …
Dispose of the used (dilute) solution on an area of land authorised for the purpose by the Environment Agency, via a licensed waste disposal company or by the use of equipment designed specifically to treat waste pesticides. After chemical treatment …
