MONITORIN NITORING G CROP ROP NUTRITION TRITION – OVERVIEW: VERVIEW: • SOIL analysis tells about availability − But is not fully reliable − Needs cross-checking • LEAF analysis indicates immediate crop status − Can support corrective sprays etc. − Problematic to interpret … weather effects … ‘norms’ change as crops age − Uncertain thresholds / critical values • GRAIN analysis tells about ultimate nutrient capture − Most accurate, precise & easy − Embraces soil supply, rooting, foliar sprays and any soil moisture issues − NEW .. so Significant value in sharing results … either informally, .. or with organised BENCHMARKING

Nutrient Management for 2020/21 Dr. Sajjad Awan Resource Management Scientist, AHDB
Maximise the benefits of nutrient management plan by cutting losses For accurate and precise nutrient management, attention to detail is essential The ‘4R’ rule for nutrient management: • Right Source: AN, Urea, DAP, TSP • Right Rate: Match the crop requirement; • Accuracy of yield prediction is crucial • Right Time: Autumn vs Spring applications • Right Place: broadcast vs incorporated/injected
Future development of RB209 Currently 3 main projects are in progress; 1 . Updating N & S fertiliser recommendations for spring malting barley: April 2021 2. NOatS: Nitrogen and Sulphur management of spring oats: May 2022 3. Nitrogen and sulphur fertiliser management to achieve grain protein quality targets of high yielding modern winter milling wheat: March 2022
