Leaf scorch (also called leaf burn, leaf wilt, and sun scorch) is a browning of plant tissues, including leaf margins and tips, and yellowing or darkening of veins which may lead to eventual wilting and abscission of the leaf. [1]
Compare yellow chlorotic leaves with the green non chlorotic leaves at left of this image. Iron (Fe) deficiency is a plant disorder also known as "lime-induced chlorosis". It can be confused with manganese deficiency. If soil iron concentration is high, in spite of this it can become unavailable for absorption if soil pH is higher than 6.5. [1]
Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...

During the summer, once the leaves begin to turn yellow and dry—usually within a month and a half to two months—snip the leaves down to three inches. Loosen the soil with a garden fork and ...
Molybdenum deficiency symptoms in most plants are associated with a build-up of nitrate in the affected plant part. This is a result of poor nitrate reductase activity. Symptoms include: [1] [2] pale leaves with interveinal and marginal chlorosis (yellowing) and necrosis (scald); the whiptail disorder in Brassica crops (especially cauliflower);
Fertilizers are essential during spring and summer when plants are actively growing and flowering, but they may be needed at other times of the year depending on the plant. Without fertilizer ...
Acidic, sandy, or coarse soils often contain less calcium. Uneven soil moisture and overuse of fertilizers can also cause calcium deficiency. At times, even with sufficient calcium in the soil, it can be in an insoluble form and is then unusable by the plant or it could be attributed to a "transport protein". [2]
