Tillage management notes: Dryness to bring new crops challenges
Continuing dry conditions are likely to cause establishment challenges for late-sown spring crops, increase micronutrient deficiencies and decrease wet-season disease infection pressure.
Dry conditions would cause farmers to question the benefit of applying N at the moment, but high soil mineral N levels indicate the need to deduce total applied rates this spring.

Dry spell could be mixed blessings:
The rise in temperature is welcome but it may not be long until some crops begin to show consequences of dryness. Some crops already lack the lushness that might be associated with a warm damp April and this could get more acute in coming weeks.
Dryness is most likely helping to reduce infection pressure for wet season diseases like septoria, rhyncho and net blotch but it may help diseases like rusts. But the single wet day could still have caused serious problems.

While rainfall amounts have been quite low for April, amounts have been variable. Micronutrient deficiency could be a particular issue for emerging spring crops but dryness could also exaggerate challenges in winter crops. If you can identify a deficiency correct it as soon as possible using foliar sprays. An ongoing deficiency is lost yield potential.
Dryness could also be a problem in later planted crops where ground got very dry and knobbly. Germination is uneven and crows and leather-jackets are problems. Roll well but be careful with emerging seedlings.
