Greenhouses are helps in the plants farming. They are very efficient in extending the planting seasons of specific plants as well as in defending the crops from various negative conditions which might be brought about by weather conditions and predators. They enhance the capabilities of nature and of man to develop plants.

Really, greenhouses have become efficient tools for man to properly cultivate vegetation. However, the proper development and growth of the crops remain in the hands of the cultivator. There are numerous factors that need to be considered to maintain a greenhouse. The heat, wetness, ventilation and shading are a few of the factors that need consideration while managing a greenhouse.

Just about the most important factors to maintain crops inside a greenhouse is fertilization. Sustaining the acceptable quantity of nutrition is required to effectively sustain the growth and development of the plants inside a greenhouse.

More often than not, greenhouse plants are categorized as heavy feeders. Heavy feeders are usually defined as crops which require considerable amounts of fertilizers. Nevertheless, knowing that the plants are heavy feeders is not enough. Knowing the ratio if the components that go into the fertilizers is as important as knowing the amount to be applied to the vegetation.

Current studies have proven that the nitrate, nitrogen and ammonium balance will impact the growth of plants. In the State of Texas, cultivators are advised to use less than 50% of nitrogen in the form of ammonium. High amounts of ammonium in turn might cause foliage burn due to toxicity.

Application

The majority of the greenhouse crop cultivators today use a liquid feeding program to be able to provide nutrients to the plants. This kind of nutrient supply program can be supplemented by slow release of granular fertilizers to the vegetation.

The frequency of the fertilizers application can have an effect on the growing of the crops also. Frequently, it is deemed important to be able to supply numerous nutrients during the peaking periods of the vegetative growing or reproductive growing of the crops. It is normally accepted that the best application system for fertilizers is a constant one. Constant feeding may be modified to be able to match the crops needs. High soluble salts may be feed to the plants every other application.

The balance among nutrients should be maintained by the cultivator so as to avoid the occurrence of deficiencies and toxicities in the crops.

Selection

There are various fertilizers which offer full nutrients needed by the vegetation. These fertilizers include nitrogen, potassium and phosphorus which are one of the most essential components required by growing vegetation. There are also fertilizers which are custom made for various crops.

Nutrients

Here are some key facts about the various fundamental elements required by greenhouse vegetation:

Nitrogen – There are numerous various sources of nitrogen which can be used to provide the nutrient to the vegetation. Ammonium nitrate, potassium nitrate and calcium nitrate are some of the nitrogen sources. If one is to provide nitrogen to the crops, he should not supply more than 50% of it in ammonium form.

Potassium – This is an essential component in the water usage of the vegetation. One of the most common sources of potassium for plants is the potassium nitrate.

Phosphorus- Phosphorus is needed by the vegetation for their growth. It is usually supplied in large amounts. However, one need to always be aware in supplying phosphorus in large amounts for it may make other nutrients insoluble. This will make these nutrients difficult for plant absorption. One of the most common ways of supplying phosphorus is through phosphoric acid or super phosphate.

Other nutrients

There are other nutrients required to be able to provide full nutrition to the crops. Plants need calcium, magnesium, sulfur, iron, zinc, copper, manganese, boron, molybdenum and chloride. Some of these are supplied through the growing medium but the others are supplied through supplemental application.

Both the primary and secondary nutrients should be incorporated to the feeding program. There are commercial blends which can suit the needs of the crops being cultivated in the greenhouse.

One must be able to check the amount and the balance of the various nutrients supplied to the crops in the greenhouse. Only through proper nutrition will the vegetation achieve their optimum growth and development potential. Quality plants can be harvested if one knows how to get around the nutritional requirements of the vegetation.
