Topic: Chemical fertilizers


In the News (Thu 17 Dec 09)

  
 INTRODUCTION TO FISH POND FERTILIZATION
If sufficient light and proper temperature are present, the nutrients in chemical fertilizers (nitrogen, phosphorous and potassium) are readily assimilated by phytoplankton and their abundance increases.
Chemical fertilizers are concentrated nutrients for green plants.
Two disadvantages of chemical fertilizers, especially for isolated farms operated on a limited budget, are that they are usually expensive and available only from commercial suppliers.

 Fertilizers   (Site not responding. Last check: 2007-10-25)
Fertilizers are expensive to manufacture, and in the U.S., approximately 2% of the natural gas consumed is used to make nitrogen fertilizer.
Fertilizers often produce plants quickly and in large quantities, but over time they become less and less effective and eventually leaving the land collapsed and the soil depleted.
Ontario's guidelines require that each field on which sludge fertilizer is to be spread must be approved and monitored to ensure the mandated nitrogen to heavy metal ratio is not exceeded.

Organic fertilizers and amendments are meant to develop a healthy and vital population of the organisms that make nutrients available to plants.
Natural fertilizers may be more expensive, but they will improve the ability of the soil to retain and release nutrients that will reduce a garden's overall fertilizer needs.
(chemical fertilizers are by definition salt-based) Furthermore, many of the less expensive forms of these products utilize sources or raw materials that are very high in chloride, also toxic to microbial life.

 Fertilizers
Chemical fertilizers are usually manufactured and have the advantage of low cost.
Thus, the inorganic fertilizers are "fast," while the organic fertilizers tend to be more "time- release." A potential drawback of organic fertilizers is that they may not release enough of their principal nutrient at a time to give the plant what it needs for best growth.
Because organic fertilizers depend on soil organisms to break them down to release nutrients, most of them are effective only when soil is moist and the soil temperature is warm enough for the soil organisms to be active.

 The TRUTH About CHEMICAL FARMING
They believe that without water-soluble chemical fertilizers they would produce very little, and that without insecticides, the little they grew would be consumed by the insects driven to their farms by their neighbors' insecticides.
This type of fertilizer is not dissolved by water -- it is gradually changed into plant food by the action of carbonic acid, nitric acid, and other organic acids that are formed by the decomposition of organic matter.
When sulphate of ammonia is used as a fertilizer, the ammonia is taken into the plant while the sulphate, left free, joins itself to hydrogen in the soil and becomes sulphuric acid, a poison that is deadly to the natural organisms in the soil.

 Fertilizer - Wikipedia, the free encyclopedia
Fertilizers (British English, also fertilisers) are compounds given to plants to promote growth; they are usually applied either via the soil, for uptake by plant roots, or by foliar feeding, for uptake through leaves.
There are six macronutrients: nitrogen, potassium, and phosphorus, often termed 'primary macronutrients' because their availability is often managed with NPK fertilizers, and the 'secondary macronutrient', and calcium, magnesium, and sulfur, which are required in similar quantities but whose availability is often managed as part of liming and manuring practices rather than fertilizers.
Horticultural fertilizers may be water-soluble (instant release) or relatively insoluble (controlled release).

Unlike chemical fertilizers, that tend to evaporate and leach into the ground water, these micro-organism's literally retain the nutrients in their own "Food Bank" and allow the plants to use what is needed now, while storing the rest for future seasons.

 The Use of Humates with Chemical Fertilizers
Intensive agricultural systems demand the use of large quantities of mineral fertilizers in order to supply the plants with basic micro-elements, such as nitrogen, phosphorus, and potassium.
The higher the amount of mineral fertilizer used, the more intensive is the erosion of the soil, the poorer the soil’s humus content, and the environment is more polluted.
The difficulty of its solution lies in the fact that water soluble potassium and nitrogen fertilizers are easily washed out of the soil, while phosphorus fertilizers, on the contrary, bond with ions of Ca, Mg, Al, and Fe that are present in soil and form inert compounds, which are inaccessible to plants.
