Mineral <strong>and</strong><br />
Environmental Stresses<br />
Poor plant growth often can be attributed to<br />
inadequate levels of essential plant nutrients.<br />
Nitrogen, phosphorous, <strong>and</strong> potassium are used by<br />
the plant in relatively large amounts, <strong>and</strong> therefore<br />
are the nutrients that are most commonly<br />
deficient. However, micronutrient deficiencies can<br />
occur as well. Many minerals in the soil, including<br />
those essential to the plant, can be toxic if the<br />
amount freely available in the soil is too high. The<br />
buildup of salts in the soil, insufficient water,<br />
extreme temperatures, <strong>and</strong> poor application of<br />
pesticides also can affect the growth <strong>and</strong> yield of<br />
a crop.
