Well that's kind of an easy question some disadvantages to organic fertilizer is that

1.)its way to expensive to buy

2.)it takes along time to start to work in the soil that it has been put in

3.)the organic fertilizers release the nutrients in a very very very very VERY s.....l......o.....wmanner(way).

Palm fertilizer is what is best for cabbage palm trees (Sago palmetto).

Specifically, cabbage palm trees benefit from specialty fertilizers. They do not need heavy nitrogen nutrient inputs. Instead, they have to have fertilizers with a higher percentage nutrient weight in phosphorus. They also like their fertilizers to include magnesium and manganese, nutrients in which they easily become deficient.

An acidifying fertilizer or compost are the best fertilizers for gardenia shrubs (Gardenia spp).

Specifically, gardenias appreciate soils that are more acidic than neutral. They therefore benefit from acidifying fertilizers that keep the soil pH below the neutral range of 6.5-7.0 on the 1-14 scale. They get the same benefits when compost is applied at fertilizer along the drip line or as mulch. Additionally, compost as mulch controls weedy competitors, favors drainage, increases soil fertility and keeps temperatures even.

Dilution and supplemental irrigation are precautions that a gardener can take so that chemical fertilizers stimulate plant growth without damaging plant roots when the concentration is too high.

Specifically, a too high concentration can be corrected by diluting the fertilizer to its correct concentration. A supplemental watering schedule can be put into effect. Adequate soil moisture levels help plant roots take in too highly concentrated fertilizers.

A fertilizer with chelated iron is the best fertilizer for evergreens with yellow needles.

Specifically, yellowed needles indicate chlorosis. Chlorosis is a chlorophyll deficiency whereby needles do not turn the expected green in color. It may be corrected by chelated iron treatments in addition to any fertilizing schedule already in effect.

A lime fertilizer is what is used to fertilize little cedar trees (Cedrus spp).

Specifically, cedar trees favor neutral to slightly acidic soils. Lime-based fertilizers help lower the soil pH to between the 5.5 to 6.5 range beneficial to cedar tree growth. But fertilizer must be applied only in the case of poor quality soils. Otherwise, young cedar trees need most a space that is clear of such shallow-rooted competitors as ferns, grasses and weeds; that is 3 feet (0.9144 meters) away from water bodies; and that receives full sunlight.

Compost or leaf litter are the best fertilizers for maple trees (Acer spp).

Specifically, maple trees benefit from ground cover that is most like their native habitat. Compost can be applied as a fertilizer along the drip line or as a mulch from about 5 inches (12.5 centimeters) from the trunk out to the drip line. Leaf litter also is a natural fertilizer option.

Otherwise, maple trees need no fertilization schedules if they grow in grass, lawn or turf that is on a regular fertilizer application schedule.

Typically fertilizer recommendations for field crops are made in lbs of the fertilizer per acre. Example - 200lbs/ac of 12-12-12 (this would supply 20 lbs N, 20 lbs P, and 20 lbs K per acre).

The Analysis (X-X-X) shows us what PERCENTAGE of each nutrient is available by weight. Example; 100lb bag of 20-20-20 spread out over an acre will provide 20lbs Nitrogen, 20% lbs Phosphorus, & 20lbs Potash (PER AREA) of the total weight of the bag, therefore an acre would receive 20lbs of each nutrient.

Respectfully, the above (answer) would yield 24lbs/acre of each. If the analysis were 10-25-50, the amount of ACTUAL AVAILABLE NUTRIENT per bag (in a 100lb bag) would yield 10lbs N, 25lbs P, & 50lbs K. Keep in mind that the pellets are composed of fillers & binders.

Compost is the best fertilizer for barberry bushes (Berberis spp).

Specifically, barberry bushes can handle a variety of environmental and soil conditions. They do not need special fertilizer attention when they grow in grass, ground cover, lawn or turf that regularly is treated with fertilizer. But for those who feel more comfortable doing so, compost is a wise choice. It provides a slow but direct and steady release of nutrients back into the soil for intake for the barberry's roots.

Reasonable prices year round and regular sales pricestend to be the norm in terms of how much artificial fertilizers cost.

Specifically, artificial fertilizers are much better known and much more widely distributed than organic equivalents. They benefit from being provided by established local businesses and multistate corporations. They can be offered at competitive and special prices.

Encourage above-ground growth is what nitrogen in plant fertilizers does to plants.

Specifically, nitrogen is one of the main nutrients that plants need in order to grow. It helps the plant to grow strong, healthy stems, stalks and leaves. But too much of it can cause lush growth of the above-mentioned body parts at the expense of fruiting and flowering.

Rapid growth of body parts may be a response to increased amounts of fertilizer to a plant. Nitrogen, phosphorus and potassium tend to be the main ingredients of artificial, chemical, inorganic, synthetic fertilizers. The three nutrients work together to quicken the pace of plant growth. Specifically, they target roots below ground and shoots above ground.

But the buds that produce fruits and flowers may get lost in the mad race for body parts to develop faster than naturally. It's easy for leaf and stem growth to take the lead. It equally becomes easy for budding and blooming to take a back seat. So flowers and fruits may be minimal, or even non-existent.
