Over the years a huge mythology has grown around the magic of fertilisers. Head gardeners of the action properties have their own secret potions. Today are the feeds that are solid, that is perfect for everything in the garden.
The truth is much less exciting. All service-food ingredients must be reduced to one and the same simple compounds before the roots are able to absorb them. This means that food items in a slurry containing organic salts may be immediately available to the roots of plants, on the other hand, plant food, locked in a mixed organic wholesale land may have to wait months before release.
There is no good or bad here, desired speed of release and the perfect balance of nutrients will depend on the type of soil, the seasons and the plant. Not one manure may be the best in all situations.
Every gardening expert agrees that nitrogen, phosphates and potash should be added to the soil. Fertilisers, which provide these nutrients are described as "organic" or "inorganic". Most authorities agree that the two types of it important, but rather different projects.
Organic fertilizers:
These materials are of animal or vegetable origin. Most of them provide nitrogen, and organic nitrogen must be transformed into simple inorganic form before it can be absorbed by the roots. This allocation shall be carried out by the soil bacteria. It is important to remember that these organisms are not active in the cold, acidic or waterlogged soils, so that the speed of the action depends on the conditions of the soil.
Inorganic fertilisers:
Some of these fertilizers are minerals extracted from the ground-Chilean nitrate is every bit as naturally as bone meal. Others are produced and have earned the titles of "synthetic" or "artificial fertilisers. The plants are not in a position to tell the difference between plant food from natural or synthetic sources-the breakdown of one and the same nutrients is observed before the takeover of the enterprise.
Inorganics are usually quick to act, security installations, fitted with it, when used as top dressing. They are usually cheaper than organic and become much more popular than old favourites. Only one organic fertilisers, bone meal, has retained his place among the best-selling plant foods.
SOLID FERTILISERS.
Garden shops display a wide range of solid fertilisers, powder or granules, which are sprinkled on the soil with hand or applied by the Distributor. Powder are dustier to be used by the granules, but usually gives the Act. Bars concentrated fertilizer for inclusion in the soil are available.
FLUID FERTILISERS.
Liquid food means the application of fertilisers which are diluted with water around the plants. It begins with soaking bags of fertiliser in the barrel of water bottles with concentrated liquid manure then became popular and in recent years, soluble powders have taken pride of place. All applied by watering can or hose end with diluent.
SERIES.
Straight fertiliser is based on a single active ingredient. It almost always contains only one main plant nutrient, although several (e.g. bone meal) contain a small amount of the second.
COMPOUNDS.
Compound fertilizers shall be based on a mixture of active ingredients. It almost always contains all three major plant nutrients although some only contain nitrogen and phosphates.
FOLIAR FERTILISERS.
Several leaves channels are solid, or fertilizers feeding sheets or blended with pesticides, such as multiple-use products. When sprayed on leaves nutrients enter the sap flow in several hours, even when root action is limited by poor soil conditions. Useful technique especially for roses and diseased plants. For maximum effect shall ensure that there is enough leaves and in the evening, when it is not provided for rain.
SUSTAINABLE RELEASE FERTILISERS.
Many popular compound fertilizers contain quickly and easily slow release sources of nutrients, so that feeding goes for some time. Truly sustainable relief manure, however, is a complex chemical, which provides a continuous supply of nutrients, it explodes in the soil, or as external coverage dissolved. The most famous example is urea-formaldehyde.
An incredible amount of my time is spent in my garden, but I am age and things become more difficult to make. So, I have decided to use a company called London landscape gardener. As far as they have given me help and advice, which I have requested. I do still just pottering around my own garden.
