Answer 1

Answer:

Explanation:

Sulphur is an important plant nutrient necessary to produce bountiful food crops. ... More sulphur is removed from the soil as a result of an increase in agricultural ... less than 10 ppm sulphur are considered to be low or deficient in plant available ... Sulphur deficiency symptoms in many ways resemble those of nitrogen - that .................................

Answer 2

Nutrient levels outside of a plant’s  sufficiency range cause overall crop growth  and health to decline due to either a  deficiency or toxicity.Toxicity occurs when a nutrient is in  excess of plant needs and decreases plant  growth or quality. y. Common nutrient  deficiencies in Montana and Wyoming  are nitrogen (N) and phosphorus (P),  with some deficiencies of potassium (K), sulphur (S), boron (B), chloride (Cl), copper  (Cu), iron (Fe), manganese (Mn) and zinc  (Zn). . Micro nutrient deficiencies are fairly  uncommon with deficiencies of B, Cl, Fe  and Zn occurring most often (Nutrient  Management Module 7, Micro nutrients:  Cycling, Testing, and Fertilizer  Recommendations; NM7).Interpreting visual nutrient deficiency  and toxicity symptoms in plants can be  difficult and plant analysis or soil testing is necessary to confirm nutrient stress.

Precautions in identifying nutrient stress

symptoms include the following:

1. Many symptoms appear similar. For  instance, N and S deficiency symptoms  can be very alike, depending upon plant  growth stage and severity of deficiencies.

2. Multiple deficiencies and/or toxicities  can occur at the same time. More than  one deficiency or toxicity can produce  symptoms, or possibly an abundance of  one nutrient can induce the deficiency  of another (e.g. excessive P causing Zn  deficiency).

3. Crop species, and even some cultivars  of the same species, differ in their  ability to adapt to nutrient deficiencies  and toxicities. For example, corn  is typically more sensitive to a Zn  deficiency than barley and will show Zn  deficiency more clearly (NM 7).

4. Pseudo (false) deficiency symptoms  (visual symptoms appearing similar

to nutrient deficiency symptoms).  Potential factors causing pseudo  deficiency include, but are not limited  to, disease, drought, excess water,  genetic abnormalities, herbicide and  pesticide residues, insects, and soil

compaction.

5. Hidden hunger. Plants may be nutrient  deficient without showing visual clues.

6. Field symptoms appear different than  ‘ideal’ symptoms. Many of the plants  shown in this module as photographs  were grown under controlled nutrient  conditions, and deficiency/toxicity  symptoms observed in the field may  or may not appear as they do here.  Experience and knowledge of field  history are excellent aids in determining  causes for nutrient stress.  In addition to the above precautions,  visual observation is also limited by time.  Between the time a plant is nutrient  deficient (hidden hunger) and visual

symptoms appear, crop health and  productivity may be substantially reduced..............
