Sulphur
This element has a general role in plant nutrition, it being difficult to explain its exact function. Sulphur is present initially in most soils and in addition in many fertilizers used, so its shortage is seldom, if ever, a problem.
Iron
This is an important element in greenhouse culture and is greatly concerned with photosynthesis. It is very insoluble and is rendered still more so by high pH figures. Symptoms of shortage are yellowing of the whole leaf, although in extreme cases the leaf can turn white, the older leaves usually being more affected than the younger ones. Deficiency usually arises from an excess of exchangeable calcium in the soil or growing medium. Excess is difficult to detect, no doubt because excess iron combines with phosphorus to form insoluble compounds, but excessive iron application is not to be recommended.
Manganese
Like iron, this is much concerned with photosynthetic activity, which is why any shortage invariably produces a leaf-mottling effect. High pH figures usually spark off any deficiency of this element, although the mottling of the leaves of young plants caused by the invariably high pH figure of many growing composts usually disappears as the pH figure drops. Toxicity of manganese is a much more common problem, particularly in older tomato borders which are steam sterilized. Here a blue-black coloration develops on leaf tips, in addition to a general drooping.
Boron
Much more has been heard of boron in recent years, largely because its importance in tomato culture has been highlighted. It would appear to have a multifarious role to play in plant growth, as its shortage in many plants causes shrivelling of leaf tips and a blueing of stems and petioles. Tomato fruits develop a corky brown layer beneath the skin. In the majority of cases, and with properly formulated growing media, boron deficiency should not arise, although it is obviously an element which can cause considerable trouble. Care should be taken not to use boron to excess, as the efficiency of boron-based weedkillers is well known.

What do fertilizers do and how often should you apply them to potted plants?
Plant fertilizers usually hep your garden plants grow because of their soils will consist of the nutrients that plants need to grow. I would apply them once a month to your plants to ensure plants are staying strong.
What are the three most important minerals for plants?
The three basic minerals that plants require for growth are: Nitrogen (N), Phosphate (P) and Potassium (K). Also abbreviated as NPK in the horticulture and agriculture industries after the elements abbreviations on the periodic table of elements. Nitrogen (N) is primarily responsible for the green, leafy growth of the plant. Phosphates (P) responsible for root development of the plant and Potassium (K) assists in flower and fruit production of the plant Micro elements are also required to sustain a balanced, deficiency free plant
Why is sulfur needed for plants?
Mineral salts (nutrients/ elements) are required by the plant in order for the ongoing metabolic processes within the cell of the plant. Elements are normally divided into two groups (macro and micro); macro are used in large amounts and are basically the building blocks of the plant, micro are used in far less quantities, but are still important to the overall health and growth of the plant. Macro include: Nitrogen, Potassium, Phosphorus Micro include: Sulfur, Magnesium and Iron
What organisms are the producers in the energy flow of an ecosystem?
usually plants or micro-organisms with similar capabilities.
Living on land required that plants?
grow roots.
Why do plants grow so quickly?
They only grow fast if they get their required nutrients such as macro and micro elements which again depends on many other factors such as soil water pH value, etc.
What are the elements required for grass to grow?
The elements that is added to the soil for plants to grow is all fertilizers. fertilizer gives the plants nutrients to grow better.
Why are trace elements important?
Plants get trace elements - micro nutrients from the soil or from fertilizer supplied by the grower. Animals get micro nutrients from plants. Humans can by food fortified with micro nutrients eg calcium in milk.
What elements are required by plants does not come directly from the soil?
Air, water, and light.
What elements required by plants does NOT come directly from the soil?
carbon carbon carbon
What elements required by plants come directly from the soil?
Nitrogen, Magnesium, Potassium and Iron

What is macronutient in plants?
Nitrogen (N) Potasium (K) Phophorus (P) they also require Calcium, Sulphur and Magnesium there are also a list of other elements that are vital known as micro or trace elements.
Type of micro elements needed by man?
types of micro element
Are the size of micro elements the same as macro elements?
Yes
Define micro and macro nutrients?
Macro nutrients = six nutrients are required by the plants in large quantities and hence these are called macro nutrients. Micro nutrients = iron , manganese , zinc , copper , molybdenum , boron and chlorine are the micro nutrients which used in small quantities.
Do plants need water and minerals to make food?
Plants require macro elements Nitrogen (N), Potassium (P) and Phosphorus (K) as well as micro (or trace elements) such as magnesium (Mn), sulphur (S), iron (Fe), boron (B), copper (Cu), Zinc (Zn) and Molybdenum (Mo) to sustain vigorous growth.The availability of these elements in the soil depends on the nature of the soil as well as the pH of the soil. Excesses of micro-nutrients/ trace elements can be just as damaging as deficiencies. Micro-nutirents are normally only required in parts that can be measured in parts per million (PPM), while macro element requirements are measured in parts per ten thousand (PPT)
