What are the different types of fertilizers?

fertilizer adds nutrients and texture to the soil that needs to provide nutrients for trees, vegetables, herbs, shrubs and flowers. There are several ways to categorize fertilizer and the most basic is whether it is organic or inorganic. It can also be classified according to its ingredients, whether it is solid or liquid, and according to its specific actions such as slow -release fertilizers that slowly dissolve and release their nutrients. The selection of the fertilizer that is used usually depends on the nature of the soil, such as whether it is acidic or alkaline; Sandy, Clay or Rocky; and weak or rich.

Organic

Organic fertilizer is natural and includes things such as bat, compost, peat moss, wood ash and manure. These are general changes in land. They do not or damage plants and may have long -term positive effects on the soil without damaging groundwater. However, organic fertilizer generally has lower nutrient concentrations than inorganic -nose.

Inorganic

Inorganic HNThe pelvis is created by man and usually comes like powder, pellets, granules or liquid. Examples of inorganic fertilizers are chemical additives that are intended for direct absorption of plants such as nitrogen (n), phosphorus (P) and potassium (K). These three basic elementary nutrients should naturally occur in healthy soil, but some plants require more of them. Other chemicals that could be included in inorganic fertilizers include calcium, sulfur, iron, zinc and magnesium.

NPK ratios

The most inorganic, concentrated fertilizer is evaluated on the basis of the percentage of nitrogen, phosphorus and potassium using a section called NPK. The amount of nitrogen will support the growth of stems and leaves by supporting protein and chlorophyll. More flowers, larger fruits and healthier roots and tubers will result from added phosphorus, which also helps the plants resist some disease. Finally, the potassium thickens and the sheets by supportinga protein. For example, this means that vegetables would be better with the ratio of NPK, which differs from what is best for roses or orange trees.

Acidical or alkaline soil

different plants will require soil that has different hydrogen levels (PH), which is measurement of how acidic or alkaline is the soil. In order to move the soil pH towards the acid side, it was possible to use inorganic fertilizer, such as aluminum sulphate or ammonium sulfate. Lime changes soil chemistry to make it more alkaline. Blood food or other organic matter can sometimes also affect acid levels in the soil.
