Recent studies have shown that more than 70 elements make up plants. most of these element are found in trace amounts, whereas carbon, oxigen, hydrogen, nitrogen, phosphorus, sulfur, magnesium, potassium and calcium are the most abundant and significant ones. plants can obtain the element, except nitrogen, phosphorus and potassium (NPK), from air or soil. However,these three elements, NPK, should be applied to plants extermally to get a higher yeild. to enrich the soil by means of NPK, fertilizer are used.
Natural or chemical substance put on the land to make crops grow better are called fertilizers. fertilizer make up an important branch of agricultural chemistry. Due to the increasing demand for fertilizers, the production of NPK and NPK compound has increased dramatically
Many mineral fertilizers (e.g KCL,NaNO3, NH4NO3 etc)contain only one basic nutrious element. such fertilizers are referred to as simple. more valuable mineral fertilizers are those which contain two or all three basic nutrious elements (NPK). such fertilizers are referred to as complex. the basic raw materials used in the manufacture of fertilizers are air (as a source of nitrogen), phosphate rock (as a source of phosporus) and sylvinite (as a source of potassium).
Phosphorus is important both for plant and animal nutrition, and most of the phosphorus pruduced today is used in the manufacture of fertilizrs. but it has a wide range of alternative application, being used in the production of pesticides, detergents, water softeners, fine chinaware and baking powder. white phosphorus is flammable, so it used in preparing fireworks and on the sides of safety match boxes.
Give me more example for fertilizer?

HapusHow the principle of cultivation to be absorbed by plants????
BalasHapusBecause all off the plants need that element for growth, so the root will automatically take the element that is needed
HapusHow the principle of cultivation to be absorbed by plants????
BalasHapusn addition to the variety of inputs and outputs, plant nutrients exist in many different forms, or nutrient pools, within the soil (Fig. 1). These pools range from soluble, readily available forms, to weakly bound forms that are in rapid equilibrium with soluble pools, to strongly bound or precipitated forms that are very insoluble and become available only over long time periods. Nutrients in solution can be taken up immediately by plant roots, but they also move with water and can easily leach below the plant root zone or be lost in runoff from farm fields. The "ideal" fertile soil has high nutrient concentrations in the soil solution when crop growth rates are high and a large storage capacity to retain nutrients when crop needs are low or there is no growing crop.
HapusExchangeable cations (see below) are a short-term storage pool that can rapidly replenish nutrient ions in the soil solution. Soil organic matter releases nutrients slowly as it decomposes, but is an important supply of N, P, S, B, and trace-metal micronutrients. Soil minerals vary from relatively soluble types (chlorides and sulfates) to insoluble forms (feldspars, apatite, mica) that release nutrients through weathering reactions with chemical and biochemical agents such as organic acids. Adsorbed anions, like phosphate and iron oxides bound to clay and organic matter surfaces, are held strongly and released very slowly, but can contribute to the long-term supply of plant-available nutrients.
NPK should be applied to plants in general to obtain higher yields. Why is that ? What is contained in NPK fertilizer so it should be applied in general?
BalasHapusIt because phosphorous and potassium. Nitrogen helps keep plant leaves healthy, while phosphorous contributes to healthy root growth.

BalasHapusPlease explain what reaction to fertilizer making process?
I hope you can undrestand
HapusThere are five major processes that happen to applied fertilizer.
• It is taken up by the crop
• It reacts with soil minerals and organic matter to become part of the soil reserve
• It can leach from the root zone with water
• It can be lost to the atmosphere as a gas
• It can move from the field through soil erosion and water runoff
What reaction happens to fertilizers that contain a lot of phosphorus in plants?
BalasHapusThere are no effect of excess phosphorus
HapusHi anisa, I want to ask. Can you mention the kinds of fertilizer and what it contains?
BalasHapusOrganic fertilizer
Hapus1. Compost
2. Green Fertilizer
3. Manure
B. Inorganic Fertilizer
1. Single Fertilizer
the contain of thats fertilizer is 1. NITROGEN (N)
2. PHOSFOR (P)
3. POTASIUM (K)
4. CALCIUM (Ca)
5. MAGNESIUM (Mg)
6. BELINES (S)
7. BORON (Bo)
8. COPPER (Cu)
What kind of fertilizer is cheaper and more efficient for farmers.?
BalasHapusyou can use
HapusOrganic fertilizer
1. Compost
2. Green Fertilizer
3. Manure
How are the positive impacts and negative impacts on the use of fertilizers? Please explain!
BalasHapusThough fertilizers have their benefits, there are also downsides to their use, particularly with regard to synthetic fertilizers. Phosphorus from fertilizer can cause algae to accumulate in lakes and ponds, killing fish by robbing them of oxygen. Fertilizers can also contaminate water with an overabundance of phosphates and nitrates, making it unsafe for consumption. Oxidized nitrogen, a byproduct of synthetic fertilizers, also increases smog, which may be related to higher incidence of respiratory illness and asthma.
Hapuswhat is the mineral fertilizer
BalasHapusA fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin (other than liming materials) that is applied to soils or to plant tissues (usually leaves) to supply one or more plant nutrients essential to the growth of plants
Hapuswheter phosfor is important to human live?
BalasHapus
HapusPhosphorus is an essential mineral primarily used for growth and repair of body cells and tissues. According to the University of Maryland Medical Center, all body cells contain phosphorus, with 85 percent found in bones and teeth. There, together with calcium, phosphorus provides structure and strength. Phosphorus is also required for a variety of biochemical processes including energy production and pH regulation.

Why is phosphorus so important and good for plant and animal nutrition?
BalasHapusbecause for their growth.
