Correct a deficiency!
Plant nutrient deficiency symptoms can present differently depending on the crop, environment, soil, and the severity of deficiency.
These are examples of symptoms intended as a general guide to identify nutrient deficiencies.
To confirm any suspected deficiency, take leaf samples from symptomatic plants and submit them for tissue analysis.
Alternatively, use our NutriAnalyticsTM AI platform to highlight any nutrient imbalances and generate recommendations
for foliar nutrient applications that can improve yields. Visit nutrianalytics.com for more information.
Nitrogen
DeficiencySlow-growing, stunted plants that develop pale yellow-green foliage (chlorosis), beginning on older leaves.
Phosphorus
DeficiencyStunted, slow-growing plants with darkened leaves that may develop a purple or reddish hue.
Potassium
DeficiencyTip and marginal leaf scorch appear in mature foliage, accompanied by chlorosis and premature leaf drop.
Calcium
DeficiencyYoung growth is malformed, with crinkled or curled leaves. Some crops may exhibit tip burn (necrosis) on leaves. Fruit can also show this deficiency.
Magnesium
DeficiencyChlorosis appears between the veins on older leaves, accompanied by the formation of brown lesions. The lower leaves also die off.
Sulphur
DeficiencyLeaves yellow, beginning with young leaves, followed by a gradual uniform discolouration
across the entire plant.
Boron
DeficiencyLeave may become thicker, distorted, brittle, and may have chlorotic to brown areas near tips and margins. Reproductive tissues are particularly sensitive to B deficiency.
Copper
DeficiencyYoung leaves may be twisted or distorted, with leaves that may show interveinal chlorosis and necrotic spots.
Iron
DeficiencyYellowing occurs between the veins (interveinal chlorosis), while the veins remain green, and the plants may be stunted.
Manganese
DeficiencyYellowing between the veins (interveinal chlorosis) begins on the young leaves first. Areas between the veins may develop gray to dark brown or black spots.
Molybdenum
DeficiencyYellowing of younger leaves, with necrotic spots (brown or gray) that may develop along the leaf margins.
Zinc
DeficiencyYellowing occurs between the veins of young leaves, leaves fail to expand and appear small, and internode spacing is reduced. Corn may develop white bands on either side of the midrib.
