knows your fields.

Good morning. You're growing winter wheat on Home Farm (42 ha, heavy clay, previous crop OSR). At this point in April you should be approaching GS31–32. Key actions now: • T1 fungicide timing — target GS32 for septoria and yellow rust protection • Second split of nitrogen if not already applied (top-dress the remaining N based on your RB209 plan) • Check for aphid pressure — BYDV vectors can still be active this month What growth stage are you at currently, and have you applied your T1 yet?

P Index 1 means your soil is low in available phosphorus — below the optimum for most arable crops. For OSR on that field next autumn, RB209 recommends maintenance plus replacement P: • Target P Index 2 for OSR establishment • Apply 80–100 kg/ha P₂O₅ pre-drilling or as a seedbed application • Consider a P-containing starter fertiliser placed close to the seed at drilling to boost early root development If you're applying slurry or digestate in spring, factor in the P content — a typical cattle slurry at 6% DM contributes around 1.3 kg/m³ P₂O₅. Have you got a recent soil sample from North Field I can factor in?

Black-grass in spring barley headlands is a competitive problem — spring cereals give you fewer herbicide options than winter wheat, but you still have some: 1. Pre-emergence: Pendimethalin (e.g. Stomp Aqua) is the most reliable spring option — apply as soon as possible after drilling, before emergence. Check label for spring barley timing. 2. Post-emergence: Your options are limited in spring barley — most graminicides (Atlantis, Axial, etc.) are not approved for spring barley in the UK. Axial Pro (pinoxaden) has some spring barley approval — check your specific label. 3. Cultural: Widen headland cultivation depth and ensure good seed-to-soil contact to maximise crop competitiveness. Longer term, rotating away from cereals into a spring bean or oilseed rape rotation will deplete the seed bank fastest. Is the infestation across the whole headland or patchy?
