Introduction to Fertilizer

Fertilizer Definition

Fertilizers are substances, usually mixtures of elements minerals, intended to provide you with the plant nutrient supplements, as a way to enhance their growth and increase yield and crop quality. In Indonesian crop is known as pupuk. The experience to produce a fertilizer or pupuk is known as fertilization. Fertilizers are part, with amendments, of fertilizer products. Fertilization comes about in agriculture along with the actions of gardening. Fertilizers were chosen from your antiquity, which were combined with the floor, empirically, the phosphates of bones, calcined or otherwise, the nitrogen in manure human and animal, the potassium of ashes.

Organic Fertilizer

The organic fertilizers are often from animal or vegetable waste. The previous are normal of business wastes, for example slaughterhouse waste: dried blood, horn roasted, fish waste, sludge from waste water. They're interesting because of their nitrogen supply towards the relatively slow decomposition, as well as their work promoting the rapid development of the microflora with the soil, however, not much enrich the soil humus stable. The latter could be of vegetable waste: green waste, composted or otherwise not, and so they comprise of as specially cultivated plants as green manure , or ready for this purpose, for example nettle manure , or algae. Fortunately they are by-products of farming, like manure, composed mostly of plant litter and manure; they're not animal, however the plants approximately digested: manure, droppings , etc.

The principle from the green manure or fertilizer takes the ancient practice that is certainly to bury the weeds. It relies on an intercrop, buried on-page. With regards to legumes for example alfalfa or clover, we have, furthermore, an enrichment in the soil available nitrogen, since their system root associates of bacteria, genus Rhizobium, effective at fixing atmospheric nitrogen. To create this method far better, seeds are sown previously from the bacteria.

Fertilizer for Crop

Crop is cultivated plants or agricultural produce, like grain, vegetables, or fruit, considered as an organization. In Indonesian crop is called tanaman. Managing soil fertility and nutrients for crop (tanaman) production involves many factors. Soil test-based recommendations provide more knowledge about whether supplemental nutrients may, or may not, be of use in growing plants with a particular soil. Fertilizer or pupuk costs have increased substantially over the past 10 years, and there is more interest in using organic fertilizers. Furthermore, there's increased manager and societal desire for managing plant nutrients to lower any negative effects inside agriculture-environment interface.

Fertilizer Application

Generally, fertilizers are integrated into the soil, but they can also be supplied by water from irrigation. The latter method is used for both soil cultivation, traditional, that above ground, on the more or less inert substrate, including compost, peat, rockwool, perlite, vermiculite, etc.. Another technique, the hydroponics, helps feed the plants without or with substrate. The roots grow in the nutrient solution, water plus fertilizer, which flows at their store. The composition and power of the nutrient solution should be constantly readjusted.

Sometimes, part of fertilization can be achieved by foliar spray. Indeed, the foliage is capable to absorb fertilizers, if they are soluble, and if the top of leaf stays wet long enough. This absorption remains limited in quantity. It is therefore rather the trace elements that could be so made, given the small quantities required by plants.

On acid soils, we can go on to liming to increase pH. This measure increases fertilizer efficiency your clients' needs plant uptake of nutrients in the soil.

Fertilizers must be used with caution. It's generally suggested for :

- to prevent excesses, because beyond certain thresholds additional contributions, not merely will no longer have economic interest, however, might be toxic to plants, particularly in trace elements, and also to harm the environment.

- to regulate their effects on soil acidity

- take into account possible interactions involving the chemical elements

- to take into consideration the restrictions imposed by additional factors of production.

NPK Fertilizer

NPK fertilizer is often a compound fertilizer containing primary nutrients a lot more than two types. In Indonesian NPK fertilizer is called pupuk NPK. Using the nutrient content of 15percents Nitrogen in the form of NH3, 15percents phosphorus by means of P2O5, and 15percents potassium in the form of K2O. Properties of nitrogen (nitrogen carrier) mainly as ammonia will increase the acidity of the soil that will support plant growth. It's explanation about NPK fertilizer or pupuk NPK.
