QGood practicesGive purmers for good practices for sustainable agriculture in the Dobrudzha region
Expert answer

Answered by: Експерт по земеделие

In short: Mostoften, flexible sowing according to moisture, conservation treatments and rootless farming, precise disease forecasting and cooperation are applied.
Southern Dobrudzha is thedriest region of Bulgaria and production is mostly irrigable.
Therefore, good practices are aimed at preserving moisture and moreprudent use of fertilizers and detergents.
Flexible sowing norm.
ET "Agro-Svetlozar Dichevski" (Varna) has switched from fixed to flexible sowing norms according to soil moisture, with drought-resistant varieties.
The result is a morestable drought yield and less seed costs.
Rootless farming and minimal cultivation.
The technology has developed in Bulgaria since 2000, mainly in Dobrudzha: first in small areas, then with the gradual exclusion of ploughing.
Fewer passes in the field.
Bomar Trade combines operations in one pass, which protects the structure and moisture of the soil.
Disease prognosis.
"Agromate" (Yambol) uses a weather station and a disease model to spray at the right moment.
This reduces the use of pesticides by up to 30%.
Cooperation.
Motor 93 Insurance Company (Babuk) shows how sharing equipment gives access to technology without much investment.
The Help Center can connect you to these farms for hands-on experience.

Frequently asked questions

QCrops & sowingDo shelterbelts and mixed cropping have a place on an arable farm?
Expert answer
In short: Yes, but they need planning — shelterbelts protect against wind and erosion, and mixtures should be tested on a small area first.

They do, but they need planning. Shelterbelts limit wind and erosion — important for the open fields of Dobrudzha — but they take up land, and next to them there may be competition for water, light and nutrients. Layout and species are matched to the terrain and machinery.

With mixed cropping, first be clear about the purpose: a mix for fodder has different requirements from a mix for grain. Check ripening times, harvesting, separation and marketing, and test the combination on a small area.

QFertilisationHow should I fertilise wheat during the season?
Expert answer
In short: All phosphorus in autumn, nitrogen split — main top-dressing at tillering, extra at stem elongation only if needed.
Stage Nitrogen, N (kg/daa a.i.) Phosphorus, P₂O₅ (kg/daa) Potassium, K₂O (kg/daa) Note
Pre-sowing (autumn) 2–4 6–8 (full amount) 0–6 Nitrogen only with early sowing or poor soil
Early spring (tillering) 5–6 — — Main top dressing
Stem elongation (if needed) 2–4 — — In a wetter year; for protein

Guide spring top dressing: 20–25 kg/daa ammonium nitrate (34%) or 18–22 kg/daa UAN. Potassium is usually not essential on chernozems; on lighter soils apply 4–6 kg/daa.

Material: Brochure 1, section 13.

QFertilisationAnd for barley and rye?
Expert answer
In short: Same principle as wheat: phosphorus in autumn, nitrogen split, 8–12 kg/daa in total; rye needs less.
  • Barley: phosphorus 6–8 kg/daa pre-sowing; potassium 4–6 kg/daa on lighter soils; nitrogen 3–4 kg/daa pre-sowing (30–40%) and 5–8 kg/daa in early spring (60–70%).
  • Rye: less demanding for nutrients; phosphorus 6–8 kg/daa in autumn; nitrogen 8–12 kg/daa in total (autumn 2–4, spring 6–8).

Material: Brochure 1, section 13.

QFertilisationWhy does my wheat lodge or have low protein?
Expert answer
In short: Lodging comes from excess or late nitrogen; protein depends on nitrogen at stem elongation when there is moisture.

Too much nitrogen causes lodging and yield loss. Applying fertiliser too late lowers quality. For protein, nitrogen at stem elongation, when there is moisture, is decisive. Copper (Cu) supports gluten and protein; on calcareous soils apply manganese (Mn), and with slow growth zinc (Zn), as a foliar spray between tillering and stem elongation.

Material: Brochure 1, section 13; Literature review, sections 4.2.3 and 4.2.6.

QFertilisationWhat yield can I expect with balanced fertilisation?
Expert answer
In short: For wheat, balanced fertilisation gives about twice as much as unfertilised (350–500 kg/daa), but more fertiliser is not better.
OptionIndicative wheat yield, kg/daa
No fertiliser150–250
Balanced fertilisation350–500
Balanced fertilisation in a good yearup to 550

The difference between an unfertilised and a balanced-fertilised field is roughly twofold. But more is not better: excess nitrogen causes lodging and yield loss, and late nitrogen leads to poor grain quality.

The preceding crop matters as much as fertilisation: in cereals, much of the yield increase comes from the preceding crop, especially in unfavourable years. After pea, wheat protein is higher than after maize.

QFertilisationThe field is uneven — in some places the crop is good, in others it lags behind. Should I add more fertiliser?
Expert answer
In short: First find the cause — drought, compaction, acidity or disease; more fertiliser will not help if nutrition is not the problem.

First find the cause. A weak crop may be due to a lack of nutrients, but also to drought, waterlogging, compaction, unsuitable pH, disease or poor emergence.

Take separate soil samples from the good and weak areas — if you mix them, the result may hide the differences. Compare the roots too. When the cause is compaction or lack of water, extra fertiliser will not solve the problem.

QFertilisationDoes it make sense to fertilise different parts of one field differently?
Expert answer
In short: Yes, when differences are lasting and the cause has been confirmed with analyses and observations over more than one season.

It does, when the differences are lasting and their causes are known. Use soil analyses, yield history and observations over more than one season to define zones with different needs and potential.

A weak zone does not automatically get more fertiliser. If the limit is shallow soil or lack of water, a higher rate may be a wasted cost. Variable-rate fertilisation is useful when the map is turned into a sound agronomic recommendation.

QGetting startedEveryone talks about sustainable farming. What should I actually change on my farm?
Expert answer
In short: Start with the problem that costs you most and change one practice at a time on a limited area.

Start with the problem that causes you the biggest losses. If it is drought, focus on keeping moisture in the soil, suitable varieties and better crop rotation. If your fertiliser costs are high, the first step is a soil analysis and checking whether you fertilise according to the needs of the field.

You do not need to change your whole technology at once. Choose one change, apply it on a limited area, and compare the yield, the costs and the final result. A sustainable practice must protect the soil and water, but it must also make sense for the farm.

Material: Brochure 1, "Sustainable farmer checklist" (section 16).

QGetting startedHow do I know whether a new practice helps me or just creates more work?
Expert answer
In short: Keep a control area with the old method, record costs and compare yield and margin — over more than one year.

Keep a comparable area under your current technology and record what you put into both: seed, fertilisers, plant protection products, fuel, labour and services. At harvest, compare the yield and quality, and then what is left after costs.

Also watch for problems: emergence, weeds, compaction, moisture retention. Lower costs are not an advantage if they lead to a bigger crop loss. One year can show whether a practice is workable, but a more reliable assessment needs observations under different conditions.

QFundingI want to buy a direct seeding drill or GPS navigation. Is there funding?
Expert answer
In short: Yes — up to 50% grant under intervention II.D.1.1, but only when a call is open; there was none as of 07.10.2026.

Yes — the main option is intervention II.Г.1.1 of the CAP Strategic Plan: up to 50% as a grant, ceiling up to €1 million. Investments focused on environmental protection and digitalisation get priority. You apply during an open call at SFA with a business plan and your own co-financing. As of 07.10.2026 there is no open call (see the young farmers' questions below).
