CULTIVATORS ADVICE FOR THE USE OF FERTILIZERS ZEOPROFIT HELLAS

CULTURAL ADVICE ON CEREALS, CRITIC, HARD, SALT WITH NEW ZEOPROFIT HELLAS FERTILIZERS.

New varieties of wheat can yield over 1000 kg per acre if all conditions are favorable. Of course, we need to be concerned not only with performance but also with quality, especially since wheat is used for human nutrition. The quality of the wheat, among other things, depends mainly on the good and balanced nourishment of the plant.
So fertilization should aim to enrich the soil with nutrients in such proportion that wheat needs to be the plant nourishment.

Setting soil pH with acidification (acidic soils) is required, while organic fertilization (with manure) is not necessary. The stalk of the reed requires the addition of nitrogen (N) in a quantity of 1% of the weight of the straw.
In soils with neutral to alkaline pH (which require cereals), traces of trace elements, especially manganese, copper and zinc, which are corrected by local acidification of the soil (N-fertilizers) or foliar lubrication with these elements, can often occur.
The phosphorus fertilizer 0-15 (5) kg P205 / acre and potassium 0-20 (10) kg K20 / acre must be done before or during sowing. Wheat needs the most potassium in the early stages (sagittarius).
Problem is nitrogen fertilization. Nitrogen is the "key lever" to increase performance and improve quality. That's why it is important to meet the plant's nitrogen needs, especially at its most critical stages of growth (sultry, start of staffing, appearance of the spike, flowering, fruiting).
Taking into account the soil reserves in N and in particular the fact that N fertilizers are immediately and for a short period of time accessible to the plant, we divide N-lubrication in doses so as to meet the plant's needs in the critical stages.
If the N-lubrication is not broken in doses and all N is given at the beginning, then, among other things (loss of N-contamination, etc.), we will have a high consumption, so that the nourishment of the plant is not balanced. Temporary deficiencies of other elements may then occur and the plants may be affected by diseases, "lean" and generally lose their resistance to adverse environmental conditions.

In general, N-lubrication of winter wheat can be done as follows:

Α) In the autumn with sowing: 0-2 kg / acre, depending on the stock of the soil in N (previous cultivation, fertilization, etc.)
Β) First dose of surface lubrication at the start of vegetation (before sowing): 3-10 kg N / ha depending on the soil reserves in nitrate NO3
C) Second dose between fracture and stem (plant height 10-20cm): 1-4 kg / acre, as surface or foliar lubrication (possibly together herbicides, CCC = strain stabilizer, etc.).
D) Third dose at the end of staffing or prior to the appearance of the spike : 4-7 kg N / acre. This dose increases the protein content of the fruit and thus improves quality.

In Dose Lubrication, there is always the risk that, due to drought, the plant will not be able to use the fertilizer - but we added it at the right time - or burn our plants (salts).
Research data of recent years show that wheat cultivation - on average and for a fairly wide area of ​​soil and climate conditions - reacts to the lubricant combination: 9 (+9) - 8 or 6 (6) -8-8
The plants responded to both nitrogen and phosphorus and potassium. We had better results when the nitrogen was given: ½ to the basic with ammonia fertilizers and the rest to the surface (before tillering ) with nitrate fertilizers.

BARLEY - OATS - RYE

Oats and rye are less demanding plants and can be grown in the poorer soils. But when they are grown on fertile soils they can yield as much as wheat. Lubrication is like wheat.
Barley used for animal feed is lubricated like wheat, since it is desirable to have a high starch content (60-85%) and protein (13-20%). When used in the brewery we want to contain a low protein content (11%) and a lot of starch and extracts. Then the last dose of nitrogen is counteracted, but the total amount of nitrogen must not exceed 4-5 kg ​​/ acre.
