best fertilizer for plants?

Answer 1

Good old homemade compost can't be beat. In how-to guides you often see expensive containers but those are entirely unnecessary.

Answer 2

John,
The reason there are hundreds of different fertilizers is because different plant have different needs. There is no correct answer for this question without knowing the plant.

Answer 3

Do not use human doodoo because it will kill them. Too much bacteria. Especially do not use it on vegetables or you will poison yourself when eating. Miracle Grow or Peters brand fertilizer both have the same ingredients. Peters brand is cheaper.

Answer 4

Any organic fertilizer is best such as simple compost or even compost tea.

Answer 5

It has to be "Miracle Grow". It comes in different forms, powder, liquid, granules, etc. and it works great.

Answer 6

I find that urine, as long as its not left out for too many days, is ideal. Not only do you produce it everyday, but it has a micronutrient balance that is unbeatable by modern chemistry. If you have a family, wow...you don't need to put anything else on your garden. Studies show that everyone puts out enough urine to feed all of their garden for the year. It can't sit for long though and for annuals it must be mixed with water at 5 parts water to 1 part urine. If it sits to long it starts exuding nitrogen as a gas into the atmosphere.
Its worked for me and mine for the last 6 years. Though I do add, every 4 years, a fine spray of sea water. Sea water is lacking in nitrogen.Necessary Nutrients
Sixteen elements are essential for plant growth. These are divided into two groups based on the amount of each needed by plants. The nine macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, carbon, hydrogen, and oxygen) are required in relatively large amounts. Of these, nitrogen, phosphorus, and potassium are the elements most commonly added as fertilizer.
The seven micronutrients (iron, manganese, zinc, boron, molybdenum, copper, and chlorine) are required in smaller amounts. Iron and manganese are the micro- nutrients most often deficient in landscape plants. An adjustment in soil pH usually corrects deficiencies of the micronutrients .

Each of these 16 elements has a specific role in plant growth. A deficiency or an excess of any one will impair plant growth until the problem is corrected.
Types of Ferlilizer
The analysis, or grade, of a fertilizer refers to the minimum amounts of nitrogen (N), phosphorus (in the form P2Os), and potassium (in the form K2O) in the fertilizer. The analysis is always printed on the fertilizer label. A fertilizer with a 10-10-10 analysis contains 10 percent nitrogen, 10 percent P2Os, and 10 percent K2O. For example, in 100 pounds of 4-8-12, there are 4 pounds of N, 8 pounds of P2Os, and 12 pounds of K2O. Conversion equations for the amounts of phosphorus and potassium are given for quantities of P2Os and K2O and are shown in Table 2.
Fertilizers may be divided into two broad categories, natural and synthetic. Natural fertilizers generally originate from unprocessed organism sources such as plants or animals. Synthetic fertilizers are man-made or processed. Synthetic fertilizers can be organic (for example, urea) or inorganic (for example, superphosphate).

Natural fertilizers commonly misnamed "organic" can also contain inorganic ores such as rock phosphate. Most nutrients from living or once-living organisms are not readily available for plant growth because they are bound in organic molecules such as proteins and amino acids and in structures such as cell walls. These nutrients are released only by microorganisms decomposing the organic matter.

Slow-release fertilizers may be synthetic or natural. Because nutrients are released over an extended period of time, slow-release fertilizers do not have to be applied as frequently as other fertilizer types. Also, higher amounts of slow-release fertilizer can be added at each application without risking injury to plant roots. Slowly released nitrogen is used more efflciently because a higher percentage is absorbed by plants. The higher efficiency of slow-release fertilizers means less nitrogen is available to contribute to pollution of streams and subsurface water The primary disadvantage of slow-release fertilizers is higher cost. When an analysis is done to determine the cost of nitrogen that is actually absorbed by the plant, however, the unit cost is actually less for slow-release materials. Several categories of slow-release nitrogen fertilizers are available in garden centers. Water-soluble or liquid fertilizers are applied either to the soil or foliage. Many water-soluble formulations are available for almost any specific need, from plant starter, high-nitrogen fertilizers to minor element formulations. Chelated iron is used extensively for prevention and control of iron deficiency in azalea, rhododendron, and other popular ornamentals.

Answer 7

Miracle gro, its fantastic, your plants will thank you :)

Answer 8

anything organically based

Answer 9

your doodoo
