The practice of applying fertilizers

August 12, 2017 17:52 | General Information About Plants

In the practice of applying fertilizers distinguish basic fertilizer, which should compensate for the natural removal of nutrients eeschestv, to restore the level of their content in the soil and lay a reserve of valuable elements for the entire growing season, and dressing, ie intermediate introductioncertain elements in powdered or liquid form in periods of vegetation, the plant when its consumption increases and they become particularly necessary.The main fertilizer is usually paid by the fall and spring tillage, fertilization is carried out at certain stages of the growing period of the plants for the season.The main task in fertilizer is the choice of the type of fertilizer and determination of the required number.It depends on the type of soil and plant needs certain nutrients.Plant Fertilizer need different, but there are some patterns: luxuriantly flowering herbaceous perennials, fruit trees and bushes in the flowering period, vegetables are more likely to need more nutrients than ornamen

tal shrubs, plants, rock gardens or green and spicy flavoring plants, as plantson poor soils should be fertilized more frequently than in the more fertile.

problem of nitrates

One of the main causes of excessive accumulation of nitrates in plants and fruits is the incorporation into the soil unnecessarily high doses of nitrogen fertilizers / Plants do not have time to absorb and process all incoming therein nitrogen to create organic matter, and his izt surpluses accumulatedin plant tissues in the form of nitrate deposits, the situation is aggravated by the unbalanced content of potassium, phosphorus and trace elements of plant nutrition, water shortages and the lack of sunlight.To avoid nitrate accumulation, the excess dose that becomes dangerous for health, should be very carefully fertilize all crops, especially those that have a high ability to accumulate nitrates: celery, all kinds of cabbage, watercress, spinach, Chinese cabbage, all kinds of lettuce,radish, parsley, radishes

rules applying fertilizers

Fertilize be targeted, which means that fertilizer application is necessary to know exactly what substance deficit occurs in the soil, the stocks of which elements need to be filled.To do this on a regular basis to do chemical analysis of the soil, at least once in 2-3 years.

Sprinkle dry fertilizer is better on rainy days or after a rain, when high levels of soil moisture and fertilizer can be quickly mastered the soil environment.

If the soil analysis showed abnormally high content of nutrients in it, you should take measures for its depletion.This action should be carried out during the site preparation for the culture, not carrying the fatty soil.These crops are primarily herbs, aromatic plants and garden herbs.For depletion of soil nutrients needed to plant strong consumers, but it is advisable not to vegetables, as most of them has the property accumulate nitrates.

Dry fertilizer should be scattered on the surface of the soil with gloved hands, avoiding windy weather.

Before making spring fertilizer should be removed last year's mulch layer after application to mulch the soil surface again.Ensure that the liquid fertilizers such as manure, fertilizers and dissolved salts do not fall on the leaves of plants, it can cause corrosive burns and tissue.After applying fertilizers as possible to spray the plants with water.In order to prevent leaching of nutrients from the soil to fertilize the composition should be calculated by the amount of fertilizer into the soil fractional throughout the season in accordance with the needs of plants Adding nitrogen-containing fertilizers for fruit trees and perennial shrubs should be stopped no later than the beginning of August.This is due to the fact that nitrogen stimulates the growth of vegetative organs of plants that do not have time to get stronger before winter and will not hardy.Under

fall tillage usually of manure, lime, or potassium phosphate fertilizers, depending on in which the soil nutrient needs element.In the spring before planting make preplant fertilization, often compost in combination with mineral fertilizers;:. - During the growing period, especially in a phase of growth, flowering and formation of ovaries produce surface fertilizer quick mineral forms of fertilizer to the plants can quickly absorb necessary for them at thissubstance development stage.As such an intermediate fertilizer suitable variety of herbal infusions.& Gt;Do not abuse the mineral fertilizers, their main purpose - to maintain the necessary for the normal development and fruiting plants the levels of certain nutrients in the soil.When introducing

unnecessarily high doses of fertilizers starting regressive processes in the soil, its microflora is disturbed, the accumulation of salts and metals, which results in soil and slagging inevitably affect the quality of plants and fruits.

Compliance fertilizer application

Perhaps the easiest and most often overlooked rule is mandatory compliance dosage fertilizers listed on their packaging.Actions on the principle of "the more - the better" absolutely unacceptable.The relevant rules of the most upotrebimykh fertilizer in a weight ratio,

main methods of processing and preparation of the soil

under natural conditions, soil structure breaks down mainly as a result of vital activity of worms and other inhabitants of the land, the gardener is usually necessary to work the land on which it isgrowing plants.Processing is necessary for weed control, land application of manure, compost and fertilizers, loosening, seal and improve soil structure.It provides seed germination, growth of young roots, as well as favorable air regime, accelerating the decomposition of organic matter introduced and the transfer of nutrients in assimilable form.Tillage should realize the two main objectives: loosen the soil, that is, give it a granular-lumpy structure, to create a favorable environment for the future

plant rooting, facilitate root system development in the thickness of the soil and keep the soil moisture, that is, to achieve such a state of the soil,where it will be able to accept and retain the maximum amount of water.

Mechanical processing stage, we keep it in good condition, and in some cases achieve improvement.To tillage brought the desired results, all activities must be carried out on time and with the proper tools.Late or incorrect handling can cause loss of lumpy structure of the natural characteristic of the fertile soil.The soil can be processed only in the physical state of ripeness.Strong destroys the structure of the processing of dry soil, structural units while spraying, gradually deteriorating in such soil aeration and water permeability, decreases biological activity.Equally, if not more than the harmful effects of having treatment too wet soil.Soil structure becomes lumpy, compacted soil surface underfoot and tools, and the result is the same: the water permeability deteriorates, the root system of the plants lack of moisture and oxygen, and when processing is necessary to spend additional forces to overcome the resistance of the soil.There are basic base and surface tillage.

Physical maturity soil

Under physical ripeness of the soil to understand the soil condition in the range of the optimum moisture content when it is completely ready for processing.There are a number of proven ways to determine the ripeness of the soil To do this, take in hand a lump of earth and compress it strongly, if the water does not seep through his fingers, and only appears on the surface and slightly spoils hand earthen manure, so the soil is ready for processing.You can also drop a lump of soil from the height of human growth, if someone on the ground when struck crumble, then gained ground state of physical maturity, it is optimal for further processing.
