Structure of the Mn 4 O 5 Ca core of the oxygen-evolving site in plants, illustrating one of many roles of the trace mineral manganese. [1] Manganese (Mn) deficiency is a plant disorder that is often confused with, and occurs with, iron deficiency. Most common in poorly drained soils, also where organic matter levels are high.
The artificial solution described by Dennis Hoagland in 1933, [1] known as Hoagland solution (0), has been modified several times, mainly to add ferric chelates to keep iron effectively in solution, [6] and to optimize the composition and concentration of other trace elements, some of which are not generally credited with a function in plant nutrition.

Phosphorus deficiency can produce symptoms similar to those of nitrogen deficiency, [35] characterized by an intense green coloration or reddening in leaves due to lack of chlorophyll. If the plant is experiencing high phosphorus deficiencies the leaves may become denatured and show signs of death.
Corn futures prices that approached $6.30 a bushel in June have since tumbled to $4.10, after U.S. farmers ultimately produced record crop yields. "I wish I sold a lot more," Henebry said.
Research at the James Hutton Institute has shown that bere is particularly able to grow in alkaline soils with low metal micronutrients, [11] such as the increased manganese use efficiency demonstrated when grown in manganese-deficient conditions such as those found in the Orkney Islands, [12] [13] [14] resistance to the fungal disease scald ...
Fertilizers are, in fact, more likely to solve trace mineral deficiency problems than cause them: In Western Australia deficiencies of zinc, copper, manganese, iron and molybdenum were identified as limiting the growth of broad-acre crops and pastures in the 1940s and 1950s. [120]

Over the last decade, solar panel prices have dropped dramatically, according to The Conference Board, with manufacturing costs falling from $5 per watt in 2000 to less than $0.25 in 2023. This ...
